Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. Refer back to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable. WARNING FIRE AND EXPLOSION HAZARD Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode.
Gun Selection WARNING PRESSURIZED EQUIPMENT HAZARD Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and cause serious injury. • Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment. • Tighten all fluid connections before operating the equipment. • Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
Setup Setup 5. Connect a fluid hose to the fluid inlet fitting. See FIG. 1. At least one hose must provide a static ground to the gun. Connect Air and Fluid Lines 1. Shut off the air supply. 2. Install a shutoff valve (not supplied) downstream of the air regulator to shut off gun air. air inlet FIG. 1 3. Install an inline air filter (not supplied) to clean and dry the gun air supply. 4. Connect a clean, dry, filtered air supply to the air inlet fitting. See FIG. 1. fluid inlet ti11094a 6.
Setup Adjust Spray Pattern 1. Rotate the air cap to achieve desired spray pattern. See FIG. 2. 7. To reduce fluid flow, turn the fluid control valve clockwise. • • ti4839a FIG. 2 If the fluid control valve is turned clockwise all the way, the gun will emit only air. If you cannot achieve the correct fluid flow with the fluid control valve, a different sized nozzle may be necessary. For smaller fluid flow, use the next size smaller nozzle. For a larger fluid flow, use the next size larger nozzle. 8.
Operation Operation Pressure Relief Procedure Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts. 1. Turn off air and fluid supply. 2. Hold a metal part of the gun firmly to a grounded metal pail. Trigger the gun to relieve pressure. Apply Fluid CAUTION Excessive atomizing air pressure can increase overspray, reduce transfer efficiency, and result in a poor quality finish.
Daily Gun Maintenance Daily Gun Maintenance Follow Pressure Relief Procedure, page 9, when you stop spraying and before cleaning, checking, servicing, or transporting equipment. Read Warnings, page 5. General Tasks • Frequently lubricate the gun moving parts with a drop of non-silicone oil. • Do not disassemble the spray gun if you are having a spray pattern problem. See Troubleshooting, page 12, for information on how to correct the problem. • Follow the Pressure Relief Procedure, page 9.
Daily Gun Maintenance Clean Gun CAUTION • Do not submerge gun in solvent. Solvent dissolves lubricant, dries out packings, and clogs air passages. • Do not use metal tools to clean air cap holes as this may scratch them and distort the spray pattern. • Use a compatible solvent. 1. Flush, page 10. 2. Remove air cap. Trigger gun, remove nozzle, and soak both in a compatible solution. CAUTION Trigger the gun whenever you tighten or remove the nozzle.
Troubleshooting Troubleshooting Problem Spray Pattern Right Spray Pattern Cause Solution Normal pattern. No action necessary. Dirty or damaged air cap or fluid nozzle. Rotate air cap (13) 180°. If pattern follows air cap, problem is in air cap. Clean and inspect. If pattern is not corrected, replace air cap. Wrong Heavy top or bottom Spray Pattern If pattern does not follow the air cap, the problem is with the fluid nozzle (11). Clean and inspect the nozzle.
Troubleshooting Problem Gun spitting. Cause Air getting into paint stream. Solution Check if fluid source is empty and fill. Tighten fluid nozzle (11). Check and tighten needle packing nut (9a). Will not spray. Excessive air blowing back. Gun fluid pressure is too high with gun triggered (cannot achieve desired flow rate). Using a low fluid pressure setting, the fluid flow is too high, making it necessary to restrict needle travel to reduce fluid flow.
Repair Repair Follow Pressure Relief Procedure, page 9. See Parts, page 16, for callout references. Disassembly 1. Unscrew retaining ring (14) to remove air cap (13b). Check o-rings (13a and 13c) and replace if necessary. 2. Trigger gun while unscrewing nozzle (11) to prevent needle damage. 3. Check o-ring (19) and replace if necessary. 4. Remove fluid control valve (8), spring (26), needle (9), and nut (7). Inspect. Replace tip (9c), needle (9), and u-cup seal (20) as necessary.
Repair Reassembly 1. Install air control valve assembly (5) with valve turned fully counterclockwise to outermost position. Torque to 85-90 in-lb (9.6-10.2 N•m). 2. Install air inlet valve assembly (27) with valve turned fully counterclockwise to outermost position. Torque to 85-90 in-lb (9.6-10.2 N•m). 3. Lubricate u-cup spreader (15) and u-cup packing (16). Install spreader (15) with tapered end facing rear of gun. Install u-cup packing (16) with open end facing front of gun. Install packing nut (17).
