Closed faucet. Inlet hose kinked Use larger garden hose; clean inlet water screen. Open faucet. Clogged inlet hose strainer Check plumbing system for leaks. Retape leaks with teflon tape. Faulty or mis-adjusted unloader valve Adjust unloader for proper pressure. Install repair kit when needed. Call local distributor. Worn packing in pump Call Dealer Customer Support. Machine has been stored in freezing temperatures Thaw out machine completely, including hose, spray gun and wand. Slow engine RPM Call local distributor. Worn or dirty pump valves Call local distributor. Nozzle is obstructed Blow out or remove debris with fine needle. Pump sucking air, inlet hose leaking Check that all hoses and fittings are airtight. Turn off machine and trigger spray gun until a steady flow of water emerges through the nozzle. Insufficient water supply Turn water on full force. Check garden hose for kinks, leaks or blockage. PRESSURE LOW AFTER PERIOD OF NORMAL USE Nozzle worn Replace nozzle. Unloader valve worn Replace unloader valve. ENGINE WILL NOT START OR STOPS WHILE OPERATING Low oil shutdown Fill engine with oil. Out of gas Fill fuel tank. Water in gasoline Drain gas tank; fill with clean fuel. ENGINE IS OVERLOADED Nozzle partially blocked Clean nozzle.
