ENGLISH 3 IMPORTANT SAFEGUARDS HAZARD: HAZARDOUS VAPORS Paint, stain and solvents, insecticides, varnishes, and other materials may be harmful if inhaled, causing severe nausea, fainting, or poisoning. • Use a mask or respirator when spraying when there is a chance of inhaling vapors. • Use protective eyewear. GROUNDING INSTRUCTIONS The product must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electrical shock by providing an escape wire for the electric current. This product is equipped with a cord having a grounding wire with an appropriate grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances. EXTENSION CORDS Use only a three-pronged extension cord that has a 3-blade grounding plug and a 3-slot receptacle that will accept the plug on the product. Make sure your extension cord is UL/ETL/CSA listed and is in good condition. When using an extension cord, be sure to use one heavy enough for the current - for lengths less than 18 feet, use a No. 18 AWG. or heavier; for lengths more than 18 feet, use No. 16 AWG. If in doubt, use a heavier gauge. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. STORAGE Make sure unit is clean and dry before storing. Store in a dry location. To prevent damage, the electrical cord should not be crimped during storage. WARNING DANGER - Improper use of the grounding plug can result in a risk of electric shock. If repair or replacement of the cord or plug is necessary, do not connect the grounding wire to either flat blade terminal. The grounding wire has green insulation, with or without yellow stripes. Check with a qualified electrician or serviceman if the grounding instructions are not completely understood or if in doubt as to whether the product is properly grounded. Do not modify the plug provided. If it will not fit the outlet, have a qualified electrician install a proper outlet. This product is for use on a nominal 120 volt circuit and has a grounding plug that looks like the plug illustrated in Figure A. Make sure the product is connected to an outlet having the same configuration as the plug. A temporary adapter which looks like the adapter illustrated in Figures B and C may be used to connect the plug to a two-pole receptacle as shown in Figure B if a properly grounded outlet is not available. The temporary adapter should only be used until a properly grounded outlet (Figure A) can be installed by a qualified electrician. The green colored rigid ear lug or the like extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box cover. Whenever the adapter is used, it must be held in place by a metal screw. AIRLESS SPRAYERS PRO 6.8, PRO 6.8 PLUS Grounding Method Attention: The temporary adapter shown in sketch B and C is not for use in Canada. Use only a grounded outlet with this unit.

This will give you the feel of the sprayer and all of its features. Follow the instructions for adjusting to the proper spray pattern. 1. Check the following: (See Figure A.) • Spray tip is screwed on tightly. • Remove container from cylinder housing. • Pick-up tube inserted tightly into the longer port of the cylinder housing. 2. Fill container with water. Refasten container to cylinder housing. 3. Plug in the sprayer. 4. Press switch. Allow a few seconds for the unit to spray water. 5. As you spray, adjust the volume control knob and notice the difference in spray volume and spray pattern. Adjust the volume control knob until you get the best possible spray pattern. NOTE: The best distance for spraying is 10 in. to 12 in. Too far away may cause excessive overspraying and too close may cause excessive spray build-up (runs). See Figure B. 6. Keep a stiff wrist. Do not arch your wrist at the beginning or the end of the stroke. Do not stop the motion of the unit while spraying. The path of the sprayer must pass beyond the area being sprayed, and the switch must be triggered on and off as the sprayer passes into and out of the spraying area. See Figure C. NOTE: Stopping the motion of the sprayer or swinging into a new stroke pattern while spray is being delivered will result in heavy spray build-up at the edges of the stroke. THINNING MATERIALS In order for your sprayer to operate properly it is important to make sure the stain or paint is thin enough to be sprayed. Thinning should be followed per the stain or paint manufacturer’s guidelines. Because materials differ from brand to brand, this guide can offer only general information. The final guide to correctly thinned stain or paint is achieving the proper spray pattern as shown in Figure D. Always follow the coverage rate recommended by the manufacturer regardless of the thinning required. Because there is a variance in viscosity between paint and stain brands, it might be necessary to thin five to 15 percent to achieve optimum spray pattern. NOTES: • Use the correct spray tip for the material being used. (See spray tip selection chart below.) • Be sure pick-up tube is tightly inserted in correct intake port. • Thin material to proper viscosity, per manufacturer’s requirements. • Before each use, check spray tip and atomizer valve for wear. • Always thoroughly clean and oil the sprayer after each use. • If you hear a low humming sound, immediately stop pressing the trigger. See TROUBLESHOOTING. • Thin material may spray better at low power setting. • Old stain or paint should be strained before using. • Stir stain or paint slowly. To prevent air bubbles, do not shake stain or paint.

The “High” setting sprays more paint, so use this to quickly paint larger, more open areas. (See Figure E.) SPRAYING INSTRUCTIONS Caution: Do not twist electrical cord. Make sure heavy objects are not placed on it. Keep electrical cord away from heat and sharp objects. To avoid a tripping hazard, make sure cord is not in a heavy traffic area. Do not use the cord if it is damaged. Use appropriate breathing protection, eye protection, gloves and clothing. 1. Empty container thoroughly and ensure the container is dry. 2. Deposit the stain or paint material into container. 3. Begin spraying by pressing the switch. Adjust the volume control knob to get the best spray pattern. A pattern with heavy spray in center (Figure F1) means the pressure is too low. Adjust the volume control knob by turning counterclockwise to increase pressure. A correct spray pattern looks like the one shown in Figure F2. The stain or paint should be evenly spread over the surface. 4. If the spray pattern is still not correct, refer to TROUBLESHOOTING. 5. Hold the sprayer 10 to 12 inches from the surface to be stained or painted. Keep the sprayer parallel to the ground without pointing it up or down. See Figure G. NOTE: TILTING THE SPRAYER IS NOT RECOMMENDED. NOTE: TO AVOID RUNS AND SAGS, DO NOT SPEED UP OR SLOW DOWN WHILE MOVING THE SPRAYER. 6. Overlap each stroke about 1/3 of the spray pattern. 7. To spray inside corners, spray the adjoining walls or surface first. The overspray will stain or paint the corner. 8. When you spray an outside corner, point the spray tip of the sprayer towards the surface. This will prevent stain or paint from being sprayed past the corner and onto surfaces you do not want stained or painted. IMPORTANT Should a low humming sound and/or irregular spray pattern occur while spraying, immediately remove plug from electrical source and thoroughly clean the sprayer. This will prevent the motor from overheating and causing damage to the sprayer. See CLEAN UP INSTRUCTIONS. NOTE: If you stop spraying for 30 minutes or longer; before continuing, retest the spray pattern by spraying on newspaper or cardboard. If you are unable to adjust the spray pattern properly, it is possible the stain or paint material has started to dry. If this happens, clean the sprayer. See CLEAN UP INSTRUCTIONS. NOTE: The small vent hole on the top of the cylinder housing must be kept clean. If the stain or paint material should dry and clog the hole in the cylinder housing, your sprayer will not function properly. See CLEAN UP INSTRUCTIONS. NOTE: If the spray pattern is still not correct, a thorough cleaning of the spray tip, atomizer valve assembly, and pick-up tube may be required. To maintain correct spraying, it may be necessary to clean the unit after dispensing five to nine gallons of paint or stain. After cleaning, reassemble the parts. AIRLESS SPRAYERS PRO 6.8, PRO 6.8 PLUS E F1 F2 Correct Incorrect G ENGLISH 8 USING THE BACKPACK USING THE BACKPACK NOTE: First, if it is not already installed, install the o-ring in the channel in the backpack lid. (See Figure H). NOTE: To maximize performance when using the backpack, some thicker latex paints may require thinning of five to 15 percent. 1. Connect the hose to the backpack with the clamp and relief spring provided (Figure I). 2. Assemble the Inlet Kit as shown in Figure J and connect to the sprayer. 3. Attach the other end of the hose to the Inlet Kit (Figure K). 4. Attached the straps to both sides of the backpack. 5. Pour up to one gallon of paint in the backpack. Do not overfill. 6. Strap on the backpack. 7. Follow the earlier instructions to begin painting. H CLEANING THE BACKPACK 1. Disassemble all sprayer parts and clean as described earlier. (See Clean Up Instructions on page 10.) 2. Pour any remaining paint from the backpack back into the can. 3. Disconnect the hose from the backpack. Clean both with water or mineral spirits, depending on the paint or stain you’ve used. See the manufacturer’s instructions on the can. I J K AIRLESS SPRAYERS PRO 6.8, PRO 6.8 PLUS ENGLISH 9 QUICK RELEASE CLEAN UP, LUBRICATION, & MAINTENANCE STEP ONE: CLEAN UP INSTRUCTIONS NOTE: Proper clean up is essential to keep your sprayer in optimum working condition. Dried by-products act like glue and will cause moving parts to stick. Failure to properly clean your sprayer will damage the unit. Taking the time to clean your sprayer immediately after use will help your sprayer last longer and work correctly. If you are finished with the project or are not going to use the sprayer within the day, you must follow these instructions for proper clean up. Never store the sprayer longer than 30 minutes without cleaning. 1. Unplug your sprayer from the electrical outlet. 2. Empty any remaining (stain or paint) material from the container. 3. Fill container approximately 1/2 full with appropriate cleaning solution. For latex, use warm soapy water; for oil-based, use a cleaning solution recommended by the material manufacturer. See Figure L. 4. Plug sprayer into an electrical outlet. 5. Press the switch of the sprayer until the cleaning solution passes through the spray nozzle for several seconds. 6. Remove container and properly discard the cleaning solution. 7. Unplug the sprayer from the electrical outlet. L STEP TWO: CLEAN UP INSTRUCTIONS FOR THE CYLINDER HOUSING 1. Unplug your sprayer from the electrical outlet. 2. Press the QUICK RELEASE buttons on both sides of the sprayer. Grasp the container with one hand and, with the other hand, slide out the QUICK RELEASE cartridge. See Figure M. 3. Pull out pick-up tube. 4. Remove all the parts from the QUICK RELEASE pump housing cartridge. See Figure N. 5. Depending on the material used, some residue may remain on the sprayer parts. Remove any remaining residue with the cleaning brush. See Figure O. 6. Lubricate all moving parts with lightweight oil. (Included, or use WD40®, 3-in-One® oil, or similar product.) 7. Reassemble the QUICK RELEASE pump housing cartridge parts. 8. Reinsert the cylinder housing into the housing. You will hear a click when the cylinder housing is engaged into the housing. See Figure P. 9. Reassemble the pick-up tube and the container. M N LUBRICATION INSTRUCTIONS Lubricating the sprayer prior to storage is extremely important to maximize the life of the cylinder housing and its components. 1. Unplug your sprayer from the electrical outlet. 2. Empty any remaining (stain or paint) material from the container, remove the pick-up tube and clean. 3. Plug the sprayer into the electrical outlet. 4. Turn the sprayer upside down. 5. Squeeze a small amount of petroleum oil into the pick-up tube port and on the cylinder pump housing, See Figure Q. 6. Press the switch of the sprayer for three to five seconds while the sprayer is still turned upside down. This will force the petroleum oil onto the piston and will protect the sprayer from drying and the piston from seizing. 7. Turn the sprayer right side up and reinstall the pick-up tube and container. 8. Unplug your sprayer from the electrical outlet. Store the unit.
