Page 6: Gun Selection
Gun Selection 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. •... -
Page 7: Setup
Setup 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) down- stream of the air regulator to shut off gun air. -
Page 8: Adjust Spray Pattern
Setup Adjust Spray Pattern 1. Rotate the air cap to achieve desired spray pattern. See F . 2. ti4839a 2. To achieve full fan pattern, open the air control valve by turning the knob fully coun- terclockwise. See F . 3. 3. -
Page 9: 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. -

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. •... -
Page 12: Troubleshooting
Troubleshooting Troubleshooting Problem Spray Pattern Right Spray Pattern Wrong Heavy top or bottom Spray Pattern Wrong Split pattern Spray Pattern Wrong Cause Normal pattern. Dirty or damaged air cap or fluid nozzle. Pressure too high for viscosity of material being sprayed. Dirty or distorted air horn holes. - Page 13 Problem Gun spitting. Will not spray. Excessive air blowing back. Excessive air leak behind trigger. Gun fluid pressure is too high with gun triggered (cannot achieve desired flow rate). Using a low fluid pressure set- ting, the fluid flow is too high, making it necessary to restrict needle travel to reduce fluid flow.
