General Repair Information General Repair Information SAE O-Ring Installation 1. Unscrew lock nut to touch fitting. To reduce risk of serious injury, do not touch moving parts with fingers or tools while testing repair. Shut off sprayer when repairing. Install all covers, gaskets, screws and washers before operating sprayer 1. Keep all screws, nuts, washers, gaskets, and electrical fittings removed during repair procedures. These parts are not normally provided with replacement assemblies. 2.
Maintenance Maintenance DAILY: Check and fill the gas tank. DAILY: Check that displacement pump is tight. Pressure Relief Procedure The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. Fluid under high pressure can be injected through the skin and cause serious injury.
Troubleshooting Troubleshooting PROBLEM Gas engine pulls hard (won't start) Gas engine does not start Gas engine doesn't work properly Gas engine operates, but displacement pump doesn't operate Displacement pump operates, but output is low on upstroke Displacement pump operates but output is low on downstroke and/or on both strokes Paint leaks and runs over side of wetcup Excessive leakage around hydraulic motor piston rod wiper Fluid delivery is low CAUSE SOLUTION Hydraulic pressure is too high Tur
