Maintenance and User Guide 1. Cleaning
Normal operation causes dust, lint, and dirt to build up around the moving parts of your CB3200/CB105. Periodically clean around all the moving parts of the machine. Pay special attention to keeping the shuttle, shuttle race, and throat plate area clean. Use compressed air or a cloth or small brush to clean off any debris.
!
2. Lubrication
Your new Cowboy CB3200/CB105 was lubricated at our factory; however re-‐ lubricate before using it. Use gun oil or high quality machine oil -‐ not WD 40. The CB3200/CB105 requires lubrication in all holes painted red (see arrows in Fig 2-‐1 and Fig 2-‐2) on a regular basis. After oiling the red painted holes, remove cover plates 2, 6, 7, 8 and 9 as shown on page 16 and do a light aerosol spray of cine gun oil. Leave it over night so the next work day any excess oil along with dirt and lint can be wiped off before use. Cowboy recommends that the machine be oiled about every 7 to 12 hours of actual usage with the best time to oil the machine at the end of the day.

How to Install the Bobbin
Fig 6-‐1
Fig 6-‐2
1. Hold the bobbin between the thumb and index cinger. Pull approximately 3-‐4” of thread off the bobbin. The bobbin should spin counter-‐clockwise from this position. If it does not then simply turn the bobbin around in your cingers and it will be oriented properly. 2. Pass the thread through the slot (A)of the bobbin case (see Fig 6-‐2) and pull the thread until the thread passes under the bobbin thread tension adjusting spring and rests in the groove on the tension adjusting spring (Fig 6-‐1). 3. Leave at least 3 to 5” of thread remaining and hanging out beyond the bobbin case. 4. Make sure the sewing machine needle is threaded. Holding the top thread of the needle taut and off to the right hand side at about the 2 o'clock position, turn the top of the hand wheel toward the operator one revolution allowing the needle to go all the way down and all the way back up. This will pull the bobbin thread up through the needle plate. The machine is now ready to sew.
7. How to Thread the CB3200/CB105
1. Place a spool of thread on the Thread Stand. 2. Pull the thread through the eyelet on the Thread Stand arm. Fig 7-‐1 3. Pass the thread through one of the holes of the chrome post on the top arm of the CB3200/CB105 (A)(Fig 7-‐1). G 4. Pass the thread through the eyelet (B), and pull the thread over the top of the tension disks (C) and down between them. 5. Continue the thread down behind the primary tension disks (D) and loop counter-‐clockwise with 1 1/2 turns bringing it from the inside over the bar (E) then through the eyelet (F) up to and through the eye on the “take-‐up lever” (G). 6. From (G) go through the eyelet at (H). 7. Make sure the needle is in its uppermost position. 8. Pass the thread through the small hole in the black collar where the needle attaches to the needle bar. 9. Thread the eye of the needle from left to right. 10. Thread the hole in the inside presser foot (I) which the needle passes through as the machine sews. 11. Pull 6 inches of thread through the eye of the needle. 12. Hold the needle thread off to the right at the 2 o’clock position. Rotate the top of the hand wheel toward the operator one full revolution to pick up the bobbin thread and pull 6 inches of thread out of the bobbin. The CB3200/CB105 is now ready to sew.

8. Adjusting the Stitch Length and Reverse Stitching
!! !! !!
! !
Fig 8-‐1
Fig 8-‐2
! To adjust the stitch length:
!
1. Turn the adjuster nut (A) (Fig 8-‐2) counter clockwise and push the handle in a downward direction for a longer stitch length. 2. Turn the adjuster nut (A) (Fig 8-‐2) clockwise and lift the handle upward for a shorter stitch length. 3. A zero stitch length is in the middle of the slot. The longest stitch length is at the bottom of the slot. 4. Pull the handle upwards to stitch in reverse. When the forward stitch length and the adjuster nut are set correctly, the machine will sew in an equal distant reverse stitch length. 5. To correctly back stitch on the same needle penetration holes; stop the machine with the needle down, then raise the needle approximately ¼” upwards, pull the reverse handle all the way up, then make several stitches in reverse. 6. To sew forward, push the handle all the way down and sew. 7. Examples of stitch lengths (Fig 8-‐1). Note these examples are thru two to four thicknesses of 7-‐8 oz. leathers.
9.
How to Adjust Thread Tension
Adjusting the needle thread tension: a. Turn the nut on the end of the aux. tension shaft (1) (Fig. 9-‐1)in a clockwise direction to increase thread tension in small amounts (A) (Fig. 9-‐1). b. Rotate the nut counter-‐clockwise to decrease the thread tension (B) (Fig. 9-‐1). c. For a greater amount of thread tension, rotate the nut on the main tension device (Fig 9-‐3) in a clockwise direction. To loosen, rotate the nut counter-‐clockwise. If you have thread loops on the bottom side of your work, tighten the main tension (Fig. 9-‐3). If the thread knot is on the top side of the work, loosen the main tension. For minor adjustments, adjust with the Aux. tension.

10. How to Adjust Thread Take–Up Spring
Fig 10-‐1
! !
The standard stroke of the thread take up spring commonly called the check spring (1) (Fig. 10-‐1) is about 3/8”. Normally the stroke or spring tension does not require re-‐adjustment.
! ! ! !
11. Adjusting The Presser Foot Pressure
1. The outside presser foot pressure is adjusted by loosening nut (3) (Fig. 11-‐1). 2. To increase the holding capacity of the outside presser foot, turn the regulator (1) clockwise. 3. To reduce the holding pressure, turn the regulator counter-‐clockwise. Be careful not to fully unscrew the regulator. It is spring loaded and will “Pop” out. If it pops out just reinsert it downward with enough pressure to depress the spring and re-‐screw it clockwise to reseat. 4. Tighten the locking nut (3) (Fig 11-‐1). The standard height of the presser foot regulator (1) from the casting to the top of the regulator screw is about 5/8” to 3/4” Fig 1 1-‐1 9

COWBOY strongly recommends replacing your needle every 8 to 10 hours of actual s=tching! Leather point needles are like knives. They get dull and require replacement.
!
CuDng point needles create significant heat going through heavy leather. Needles lose their temper (hardening) with heat which leads to bent or broken needles. A broken needle may cause damage to your machine and should be immediately replaced.
