POSSIBLE SOLUTION Add fuel. 2 Low oil. Add required amount of oil. 3 Pressure builds up after two pulls on the recoil starter or after initial use. Squeeze gun trigger to relieve pres sure. 4 Choke lever in the NO CHOKE position. Move choke to the CHOKE po si tion. 5 Spark plug wire not attached. Attach spark plug wire. 6 Engine ON/OFF switch in OFF po si tion. Place engine ON/OFF switch in ON position. 7 Choke lever in the CHOKE position on a hot engine or an engine that has been exposed to thermal heat for a long period of time. Move choke to the NO CHOKE po si tion. 8 Fuel valve closed. Move the fuel valve lever to the OPEN position. 9 Spray wand not in high pressure. See Spray Wand Nozzles under Operation. 10 Low water supply. Water supply must be at least 5 GPM @ 20 PSI. 11 Leak at high-pressure hose fitting. Repair leak. Apply sealant tape if necessary. 12 Nozzle obstructed. See Nozzle Cleaning under Maintenance. 13 Water filter screen clogged. Remove and clean filter. 14 Air in hose. Turn off the engine, then the water source. Disconnect the water source from the pump inlet and turn the water source on to remove all air from the hose. When there is a steady stream of water present, turn water source off. Recon nect water source to pump inlet and turn on water source. Squeeze trigger to re move re main ing air. 15 Choke lever in the CHOKE position. Move choke to the NO CHOKE posi tion. 16 High-pressure hose is too long. Use high-pressure hose under 100 feet (30.48 m). Lengthen water supply hose instead of high-pressure hose. 18 (Troubleshooting Codes cont.) CODE 17 POSSIBLE CAUSE Spray wand not in low pressure. POSSIBLE SOLUTION See Spray Wand Nozzles under Operation. 18 Chemical filter clogged. Clean filter. 19 Chemical screen not in cleaning solution. Make sure end of chemical hose is fully submerged into cleaning solution. 20 Chemical too thick. Dilute chemical. Chemical should be the same consistency as water. 21 Worn seal or packing.
