Preparing the Sailrite Apprentice for Use Unpackaging the Machine and Case Inserting the Needle © Sailrite Enterprises, Inc. The Sailrite Apprentice is shipped in one box. This makes setting the machine up easy. Pull the machine and case out of the shipping box. To do so, carefully turn the box over on the floor with the box flaps open and then pull the box off. Since there is no handle on the top of the case this is the easiest way to remove the machine. The machine will be upside down (as apparent by the rubber feet on the case bottom). Turn the machine upright. Unlatch the case hinges and lift the top of the case off. Remove the foam insert inside the case top. Also remove the thread stand and cone of thread packaged between the foam and case top. At the right forward corner of the machine there is a plastic latch which pivots to hold the machine base down in the case cutout. Pivot this latch out of the way. Cut the plastic band holding the machine to the case and remove the protective paper pads. Next lift the machine and it will pivot back on the case hinges. In the bottom of the case is another foam cushion. Carefully pull this cushion out. Slowly lower the machine back down and you are ready to follow “Plugging in the Foot Control". We recommend that you save all packaging materials. These items were designed to protect the machine and case from damage and must be used if the machine is sent in for service. Carriers will not pay insurance claims on improperly packaged machines even if they are insured. System 130 Needle Flat side of needle shank should be inserted to the right or towards the balance wheel. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. The Needles © Sailrite Enterprises, Inc. Plugging in the Foot Control System 130 (15x1) needles sizes 12 to 20 are recommended for this machine. A size 18 to 20 needle is used for most medium to heavy sewing. These needles are available in Sailrite's catalog. (See "Inserting the Needle" this page.) Note that these needles have one distinct flat side. When the needle is installed, this flat side should be facing to the right or towards the balance wheel as you face the machine. If the needle is inserted the wrong way the Sailrite Apprentice will skip stitches and break thread. © Sailrite Enterprises, Inc. 1. 2. Select the proper needle size for the fabric to be sewn. Turn balance wheel toward you until the needle is at its highest position. Loosen the needle clamp screw by turning it counter clockwise. Remove old needle from the clamp. Insert new needle into the clamp with its flat side facing toward the right (towards the balance wheel). Push the needle up into the needle clamp as far as it will go. Tighten the needle clamp screw firmly. © Sailrite Enterprises, Inc. 3. 4. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. 5. 5 © Sailrite Enterprises, Inc. Machine Lubrication The machine was thoroughly oiled prior to shipment. It should be oiled frequently (at least prior to each major project). Oil all metal to metal working parts as shown in the photographs which follow. Apply one or two drops of sewing machine oil in each area. After oiling, sew briefly with some scrap material to prevent the possibility of staining on your fabric. © Sailrite Enterprises, Inc. Open cover behind the machine and oil all moving parts. © Sailrite Enterprises, Inc. Arrows indicate lubrication points.

Preparing to Sew © Sailrite Enterprises, Inc. The Balance Wheel When sewing, winding bobbins, or changing needles it is important to always turn the balance wheel towards you from the top (counter clockwise). Loosening the balance wheel allows for the winding of bobbins without needle movement. To loosen the wheel, hold it tight with your right hand and with your left hand turn the clutch knob counter clockwise until it stops. (Fig. 1) To tighten and reengage the needle drive, reverse the procedure. Winding the Bobbin Loosen the balance wheel as explained above. Place an empty bobbin on the bobbinwinder spindle and push it to the end of the spindle. Make sure that the spring on the spindle engages the notch on the bobbin. Now press the flat chrome lever toward the machine until the bobbin is held in place by the metal finger that fits between both flanges of the bobbin (Fig. 2) Thread the bobbin as shown and hold the short thread tail that is led through one of the holes in the side of the bobbin. To fill the bobbin press the machine's foot pedal down gently operating the machine. Continue holding the short tail until the bobbin is about 10% full. Stop and cut the thread flush with the side of the bobbin and once again apply power to finish filling the bobbin. The bobbin will automatically stop and release when full. Cut the thread and remove the bobbin from the spindle. Tighten the balance wheel's clutch knob in preparation for sewing. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. Note: If the thread is wound unevenly on the bobbin, adjust the bobbin winder thread guide on the bed of the machine. Loosen the screw and slide the tension thread guide left or right as needed. © Sailrite Enterprises, Inc. Fig 1 — Loosening the balance wheel If the bobbin does not fill full enough or overfills an adjustment is necessary. At the top of the chrome lever which engages the bobbin there is a thumb adjustment screw. Turning the screw counter clockwise will increase the amount of thread on the bobbin and turning it clockwise will decrease the amount. © Sailrite Enterprises, Inc. Push here to engage © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. Fig 2 — Bobbin on spool pin with thread started 7 © Sailrite Enterprises, Inc. The Thread For sail and canvas work we recommend using V-30, V-46, V-69, V-92 and V-138 Dacron® sailmaker's thread or Tenara M1000 thread. These threads are available in the Sailrite Catalog. © Sailrite Enterprises, Inc. Choose from 5 Dacron thread weights: V-30 with a No. 12 needle and fabric less than 1 1/2 ounces. V-46 with No. 14 or 16 needle and fabric less than five ounces. V-69 with No. 18 needle. Best for fabrics up to eight ounces and with 9.5 acrylic cover fabrics. V-92 with 20 needle, fabric up to ten ounces. Also used for 9.5 acrylic cover fabric. V-138 with No. a 20 or 22 needle and fabric over 10 ounces. Note: this heavy thread requires frequent bobbin changes. © Sailrite Enterprises, Inc. Continuous filament, spun and monofilament threads can be used in the Apprentice. Nylon and polyester continuous filament threads have a wide variety of uses from the sheerest lingerie to the heaviest canvas, leather and automotive applications. They feature superior strength, stretch and recovery properties and excellent resistance to chemicals, bacteria, mildew, wear and abrasion. Polyester continuous filament thread stands up to the weather better than nylon and is many times better than natural fibers for outdoor applications. It is highly recommended for marine use. Spun thread which is sold in home sewing centers is not as durable as continuous filament thread. It is best used for sewing clothing. Spun thread sewability is very good because the soft surface tends to make tension adjustment easy and consistent. Monofilament thread is often used in upholstery because of its clear color. © Sailrite Enterprises, Inc.

Pull out about a six inch tail of thread Finger 1. Spring loaded lever 4. Snap thread under tension plate to this position 2. To remove the bobbin case grasp and lift the spring loaded lever and pull the bobbin case out. With the lever held open the bobbin is captive in the bobbin case. Release the lever and the bobbin will fall out. To install the bobbin case pull and hold outward its spring loaded lever (this keeps the bobbin from falling out) and push the case onto the axle of the gib hook. The finger of the bobbin case should be pointing upward. NOTE: if you hold onto the spring loaded lever until the bobbin case is completely installed, upon releasing the lever there will be no clicking noise. It will simply lock onto the axle. If you release the spring loaded lever before the bobbin case is pushed completely in place, you will hear a click as you push it all the way on. © Sailrite Enterprises, Inc. 3.

Figure 2 Figure 1 Threading the Machine © Sailrite Enterprises, Inc. 1. 2. 3. Turn the balance wheel toward you until the take up lever (E) is raised to its highest position. Place a spool of thread on the thread stand and pull the thread up off the top of the cone to the arm loop of the thread stand. Pass the thread through thread guide (A) at the top back corner of the face plate. Continue down to the thread tension regulator and place the thread between the two tension discs (B), bring the thread under and then up the right side (to your right when looking at the needle end of the machine) of the regulator. Next pass the thread over the metal thread guide (C), and down into the loop of fine wire called the "take-up" or "check" spring (D). Continue up to the take-up lever (E) and thread it through the hole from left to right. Pull the thread into the guide in the face plate (F) (Figure 1), through the thread guide at the lower end of the needle bar (G) and then from left to right, through the eye of the needle. (Figure 2) As you sit in front of the machine ready to sew, left to right is the correct threading. Picking Up the Bobbin Thread After the machine is threaded and the bobbin/ bobbin case is installed, it is time to pick up the bobbin thread: 1. Hold the needle thread loosely in your hand and rotate the balance wheel toward you until the needle moves down and then up to its highest point. Now pull the needle thread gently. The bobbin thread should come up with it in the form of a loop through the throat plate needle hole. Grasp this loop and pull until the end of the bobbin thread appears. If the bobbin thread does not appear when the needle is lowered and raised, check to be sure that at least 5 or 6 inches of bobbin thread is hanging loosely from the bobbin case and go through the procedure again. When the bobbin thread is exposed, run the needle thread through the opening in the center of the presser foot and lay it back on the throat plate. © Sailrite Enterprises, Inc. 4. 2. 3. © Sailrite Enterprises, Inc. 5. 6. 4. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. 9 © Sailrite Enterprises, Inc. Starting to Sew 1. 2. 3. Place the material to be sewn under the presser foot and use the hand lever to lower the presser foot onto the material (see "Hand Lever" previous page). The thread from the needle and the bobbin should be behind the foot as you start to sew. Hold them down with your finger. Press the foot control pedal to begin sewing and release the trapped threads after the first couple of stitches are made. set the lever at 12 and then loosen the thumb screw and move the screw up until the restricting cam hits the lever. Tighten the screw and the lever cannot be moved down any further than 12. By the same token the lever can only be moved up enough to produce a stitch roughly the same size in reverse. The numbers on the plate indicates the number of stitches per inch: ex.: 12 = 12 stitches in 1 inch. See photo this page. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. Always turn the balance wheel of the machine toward you to reduce the possibility of a thread jam in the lower mechanism. And never operate the machine (when threaded) without material under the presser foot. If you do, the machine will most likely "lock up" and be inoperable until the thread jam is cleared (see "Removing the Hook to Clean the Race and Free Jams" pp. 13-14). Sewing in Reverse To sew in reverse: 1. Raise the stitch length lever above the center line. The higher you place the lever above the center line, the longer the reverse stitch. Note: When switching to reverse be sure the needle is either all the way down or all the way up before pushing the lever up. To return the lever to the forward position follow the above notation. © Sailrite Enterprises, Inc. Regulating the Stitch Length Stitch length is adjusted by moving the stitch length lever up and down. All the way down is full stitch length in forward and up is full length in reverse. For outdoor canvas work it is normal to work with the longest stitch possible. Additional needle penetrations can cause material puckering (called needle pucker). To the left of the lever is a thumb screw. For the lever to move the full range of stitch length the thumb screw should be tightened at the bottom of its travel. The thumb screw moves a restricting cam which allows for holding a limited range of stitch length. In other words, if you don't want to sew more than 12 stitches per inch you can 2. Tension Adjustment Understanding the tension adjustment on a sewing machine is very important. Tension adjustment refers to the combination of tension on both the upper thread and the bobbin thread. The correct combination of thread tension (upper and bobbin) results in a stitch that looks identical on both sides of the material. That is, the knots of the stitches are pulled into the fabric and are no more visible on the top than on the bottom. The primary problem when using a heavy thread is incorrect upper thread tension. When stitch tension is a problem, it is usually a consequence of too much or too little tension on the upper thread. Tension changes to the bobbin thread should only be made if adjustment to upper tension still leaves room for improvement (see p. 12). Note: in general bobbin tension requires just a two ounce or so drag on the thread (a drag similar to the one you feel when you pull dental floss off a spool). The Apprentice has a thread regulator through which the upper thread runs (see "Adjusting Thread Tension" p. 12 and photo below). The tension knob of the regulator can be turned through a range of about six revolutions to compress a spring that squeezes two disks together. Note that when the presser foot is lifted the upper tension disks are pushed apart. This is to release the top © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. 10 © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. thread tension so that fabric can be removed from under the machine foot without fighting thread tension. embroidery work. At this setting the feed dog no longer touches the fabric. Decrease the upper thread tension and, if necessary, the bobbin tension. Too much thread tension will cause puckering of the fabric. Place home sewing machine thread spools on the thread post on the top of the machine and be sure the thread spool is turning in a clockwise manner (if you have not already installed the spool pin, it is in the plastic parts box which comes with the machine. The pin simply threads into a hole on the top of the machine). This will insure that the post that it rides on is tightened as opposed to loosened. See photo below. 5. © Sailrite Enterprises, Inc. Removing Material from Under the Presser Foot 1. 6. Stop the machine with the needle at its upward most position. Lift the hand lever to raise the presser foot. Pull the material straight back to remove it from under the foot. Note: it sometimes helps to rock the balance wheel forward and back to free the thread from the tension assembly. © Sailrite Enterprises, Inc. 2. 3. © Sailrite Enterprises, Inc. Understanding and using these techniques will enable you to use and enjoy your Sailrite Apprentice machine to its fullest potential. Doing upholstery and canvas work has advantages far beyond the money saved — it also provides a confidence and satisfaction that comes from self-reliance. And it is surprisingly easy to move from simple repair work to full fledged fabrication of the most ambitious projects. Each step in this progression is an important step on the way to becoming a better canvas worker. © Sailrite Enterprises, Inc. Using the Sailrite Apprentice for General Sewing 7. Wind thread bobbins by placing the thread spool on the spike shown in Photo A and leading the thread to the bobbin winder shown in Photo B. See pages 7 & 18 for all other instructions on winding bobbins. © Sailrite Enterprises, Inc. A. B. When sewing in light to moderate weight fabrics, be sure to: 1. Use an appropriate thread. Home sewing machine thread should be used for making clothing or items for the home. Nylon thread is often prefered for interior upholstery. Select an appropriately sized needle, i.e. match the fabric and thread weight to the needle size (see Fabric, Thread, Needle Chart). And, be sure to use the same thread for both the needle and the bobbin. Decrease pressure on the foot. In heavy fabrics a great deal of pressure aids in feeding. In lighter fabrics too much foot pressure may scuff the fabric. On page 9 see the location of the screw to adjust the foot pressure. Do not be afraid of loosening the screw too much. If it comes out, just screw it back in a few turns. Use the appropriate feed dog position. Three are available: "Normal" for canvas and upholstery weight materials, "Silk"and "Embroidery" (see photo). Use Silk (a reduced feed dog height) when sewing delicate fabrics. Use Embroidery when darning and doing © Sailrite Enterprises, Inc. 2. 3.

Fine Tuning the Sailrite Apprentice The more we understand our machines, the better they work for us. It is surprising that sewing machine companies do not make information concerning their machines' mechanical needs available. Their handbooks are written as though companies expect that mechanical skills are completely beyond the user. The fact is that sewing machines are relatively simple. Their adjustment is easy for the average user willing to acquire a little knowledge. The following will help in this regard. this task is completed, the oscillating hook reverses its direction and returns to its original location. This movement is created by a simple yoke and cam arrangement on the top shaft of the machine. It is a relatively inexpensive design but quite reliable and wholly satisfactory for canvas work. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. Needle The Class 15 Machine © Sailrite Enterprises, Inc. The Apprentice has a class 15 shuttle hook system. The gib hook in the bottom of the machine moves around the bobbin case back and forth (see Illustration) It oscillates half way round and then back the other way a half turn. The purpose of the hook is to pick up the upper thread at the needle and carry it down around the bottom of the bobbin case where the upper thread loop is pulled up and tight by the take up arm above the needle bar.

Common Sewing Machine Problems © Sailrite Enterprises, Inc. No matter how good the machine is there will be times when adjustments are necessary. When this happens just pick up these instructions and let us help. Skipped stitches, for example, are an indication that something needs adjustment. There are a number of mechanical adjustments that can overcome this problem. In order to utilize them properly, let us review the fundamental operation of a lock stitch sewing machine. A sharp "hook" (the gib hook) rotates around the cage that holds the bobbin thread under the machine. This hook passes right next to the rising needle and catches a loop formed in the upper thread by the needle as it comes up. After catching this loop, the hook pulls it down until it circles around the entire bobbin of lower thread. The two threads are thus interlocked and a stitch is formed. As the needle continues to rise, a "take up arm" also rises to pull the excess thread up from the bottom of the fabric. The thread comes up out of the cloth because of the tension disks that tightly clamp the thread on the spool side of the take up arm. with adhesive if you are using basting tape or sewing insignia cloth. In either case, the new needle will resolve these problems. Also make sure that the needle is in correctly (see p. 5). And, check the upper thread path. At the needle the thread should pass from left to right through the needle eye. © Sailrite Enterprises, Inc. 2) Adjust the Foot Pressure Next check for adequate foot pressure. Heavy, closely-woven materials like sailcloth and canvas can make the withdrawal of the needle from the fabric difficult. If the presser foot is lifting as the needle comes out of the cloth the effect is the same as if the needle were not going far enough into the cloth — the loop that it forms will be too small. To solve this problem more downward pressure must be placed on the center presser foot. The presser foot is spring loaded and it is adjustable. There is a roughly 1 inch threaded screw that protrudes out of the top of the machine just above the presser foot. Turn the knurled head clockwise to increase presser foot pressure by compressing the spring underneath. Most sail and canvas work will benefit from a good deal of pressure. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. Skipped Stitches If your machine is skipping stitches we know from the discussion above that the hook is not catching the thread consistently. It is usually because either the thread is not being held down by the fabric as the needle is withdrawn and, thus, a loop of thread is not formed for the hook as it passes the needle. Or the hook may not be passing the needle at the proper time, i.e., it may be passing the needle before a loop is formed or, at the opposite extreme, after the thread has been pulled upward out of the path of the hook. 3) Reset the Needle Bar: If skipped stitches continue to be a problem, it is almost certainly a matter of the machine's having gone out of time. The timing of a class 15 machine is checked by determining the relationship of the needle to the gib hook point. The "height" of the needle bar should be checked and adjusted first. Lower the needle bar to its lowest position by turning the balance wheel toward you. To determine the proper height of the needle bar measure the distance between the top of the needle eye and the gib hook when the gib hook is directly behind the needle and the needle is on its way up. This distance should be about 1/32 of an inch as illustrated on page 16. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. Five Ways to Eliminate Skipped Stitches 1) Change the Needle The first thing to do is simply change the needle. A bent needle will cause skipped stitches because the loop is not where the hook "expects" it to be. The needle could also have become fouled © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. 15 © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. The needle bar is locked into its drive collar with a single screw accessible through a hole on the inside of the machine arm when the bar is at the bottom of its travel. The screw has a slotted head (see Illustration 2nd column — end cover plate is removed). Five Step Review of Setting the Needle Bar: © Sailrite Enterprises, Inc. a. Remove left end cover of sewing machine. b. Turn balance wheel to lower needle bar to lowest position. c. Rotate the balance wheel a little further until the gib hook point is right behind the needle. Determine if the top of the needle eye is about 1/32" below the gib hook. If not make a judgement as to which direction the bar must move. d. Turn the balance wheel again to set the needle at its lowest position. Unlock the drive collar by loosening a single screw accessible through a hole on the inside of the machine arm (See Illustration above). e. Gently twist the needle bar up or down as needed. After moving the bar be sure to twist it so that the thumb screw which secures the needle is facing the inside of the sewing machine arm. Now tighten the drive collar set screw. Remember that you must have the needle bar at the lowest point of its travel prior to resetting the bar. f. Go back to step "c" to confirm that the setting is correct. © Sailrite Enterprises, Inc. 1/32" © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. 16 © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. TROUBLE SHOOTING 1. The machine does not seem to be getting any electrical power. Is it plugged in!!! © Sailrite Enterprises, Inc. 2. The thread is balling at the needle or breaking. To troubleshoot this problem start with "a" below and stop as soon as the problem is solved. a. First check for the most common problem—incorrect needle insertion (see p. 5). Also be sure the needle is not twisted. When viewed from the top of the machine, the eye of the needle should be on the axis from 3 o'clock to 9 o'clock. b. If the needle is inserted correctly, be sure the needle size and thread weight are compatible. (Use the thread selection guide found on p. 8 or see the thread section of your Sailrite Catalog.) c. If you have been sewing through one of the double sided basting tapes, gumming of the needle may have occurred. Clean the needle with rubbing alcohol. d. Be sure that there is not too much thread tension. To check—sew in two layers of the material being used and loosen the upper thread tension until the thread knots become visible on the bottom side of the fabric. Now tighten the upper thread tension just enough to draw the knots into the material. Go back to the sewing project and test to see if the problem is solved. e. Check for a bur on the gib hook. Look for burs on the pointed hook which catches the thread. Smooth any burred areas with an emery board. f. Check your needle bar height (see pp. 15 and 16). Sewing in heavy materials can pound the needle bar upward. Reposition the needle bar and test the machine to see if the problem is solved. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. 4. There are loops on the underside of the fabric. If there is a tangle on the bottom side of the fabric, there is not enough upper tension. More than likely the thread has not been pulled snugly between the tension disks on the upper tension assembly or it is not between them at all. Lift the presser foot (this will push the two disks apart) and firmly pull the thread against the center shaft between the disks. Now, when the presser foot is dropped, you should see the disks close on the thread and there should be a good deal of tension on the thread when you pull on it. If this does not solve the problem, check to make sure that the tension knob has been tightened sufficiently. © Sailrite Enterprises, Inc. 5. How does the thread stand go together? See illustration this page. 6. When starting to sew the thread pulls out through the needle. Simply pull out a longer thread tail and trap it with your finger. Also confirm you are threading the needle form left to right. © Sailrite Enterprises, Inc. 7. A rat's nest is formed in the first few inches of sewing and then it clears itself. This can be eliminated by trapping the thread tails from the needle and the bobbin as you start to sew. © Sailrite Enterprises, Inc. 8. When stopping to turn a corner even with the needle buried the machine skips a stitch at the turn. Bury only the needle tip in the cloth. This allows the machine to create the appropriately sized loop for the hook to pickup. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. 9. The needle hits the needle throat plate when reversing sewing directions. To eliminate this problem, be sure to change sewing direction, i.e., forward or reverse, when the machine is stopped with the needle either out of the material or in the fully down position in the material, i.e., at the bottom of its stroke. 17 © Sailrite Enterprises, Inc. In the needle up position, the foot moves the material but it cannot bend the needle which may cause it to hit the throat plate. In the needle fully down position, the outer portion of the walking presser foot is up and, thus, does not move the fabric which would bend the needle and cause it to hit the throat plate. © Sailrite Enterprises, Inc. 10. When using Tenara (Gore-Tex) thread the machine skips stitches. Tenara thread is very slippery and often requires the use of a smaller needle. We recommend using a No. 14 needle with Tenara M1000. The problem which occurs with a too large needle is that the shaft of the needle does not hold the slippery thread firmly enough against the fabric to enable the formation of a proper loop and, so, the hook cannot catch it and form a stitch. If all else fails, lower the needle bar slightly. This will also have a tendency to increase the size of the loop. © Sailrite Enterprises, Inc. 11. There is no penetration power. The flywheel rotates but the needle does not penetrate the fabric. The problem is that the clutch is not engaging with sufficient authority and, as a result, the needle has little penetration power. To solve this problem follow the instructions below. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. If the clutch does not engage with enough authority, test for the source of the problem and resolve it as follows: 1. Remove the clutch stop screw. 2. Tighten the hand clutch screw as tight as possible. 3. Does that solve the problem? If so, the clutch washer must be rotated 180 degrees to permit further tightening of the hand clutch screw when the stop screw is in place. 4. If the problem remains, the clutch washer may be worn down and require replacement (a temporary fix can be accomplished by bending the inner prongs out three or four more degrees with a pair of vise grip pliers). Or the clutch washer could simply be installed backwards so the inner prongs are bent towards the machine (wrong) instead of away from the machine (right). © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. 12. The bobbin is not filling evenly—there is too much thread on the left or on the right. Turn to p. 7 "Winding Bobbins" and locate the "bobbin tensioner". If the bobbin is filling with too much thread on the left move the tensioner right by loosening its securing screw. If there is too much thread on the right, move the tensioner left. Tighten the screw once the correct position is found. 14. When removing fabric from under the machine it pulls hard and three strands of thread come up through the throat plate. This happens when removal is attempted with a partial stitch in process. The hook under the machine has a loop of thread round it. To solve the problem be sure to turn the machine forward by hand after stopping until the take up arm has just passed the top of its travel. At this point the hook will have released its last loop of thread and proper upper tension will have been applied, finishing the stitch. 18 © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. © Sailrite Enterprises, Inc. OPTIONAL ACCESSORIES FOR THE SAILRITE APPRENTICE A Binder Attachments Note: this photo shows the binder from the back to make the feeder ledge more visible. Feeder Plate © Sailrite Enterprises, Inc. Two different styles of binders are available. One is stationary and must be removed to continue normal sewing. The other is a “swing away” style that can be left attached to the machine at all times and swung into position to apply binding tape to a Bracket Slot fabric edge. Two binder sizes are available. One is used with 3/4" binding tape and the other with 1" binding tape. A 1” binder can also be used to apply 7/8” centerfold acrylic binding tape. © Sailrite Enterprises, Inc. Installing and Using the Binder Two screws are used to attach the binder to the bed of the machine. Line up the binder's bracket slot (see Photo A) with the two predrilled holes in the bed of the machine shown in Photo B. Place a washer (for the “swing away” binder a single rectangular washer with two holes is used) on each of the attachment screws, insert the screws into the bracket slot and then into the holes in the bed of the machine Tighten the screws. In general a binder should be installed so that the “feeder ledge” (see ledge in photo A) is positioned close to the right toe of the feed dog or right outside of the presser foot. Angle the binder slightly toward the presser foot before it is tightened down to better feed the binding under the foot. For the “swing away” binder final left and right adjustment can be fine tuned by loosening the large thumb screw and sliding the binder head into position. Tighten the thumb screw when satisfied with the positioning. The two screws found near the feeder plate can be used to slide the plate back and forth. The mouth of the feeder must be very close to the feed dogs in order to keep stitch placement consistent. Now feed proper sized binding tape into the “wide” end of the slot on the feeder plate. Push it in as far as you can. Finish the insertion by using a screwdriver blade to push the binding completely through the slot. Push the raw edge of the material requiring binding into the crease of the binding as it exits the binder mouth and start sewing. As long as the material is feed tightly into the crease of the binding the result will be a perfectly finished edge. Feeder Ledge © Sailrite Enterprises, Inc.
