After Each Use
Water should not remain in the unit for long periods of time. Sediments or minerals can deposit on pump parts and freeze pump action. Follow these procedures after every use:
1.If the detergent siphoning system was used, clean the tube as described in Cleaning Detergent Siphoning Tube.
2.Shut off engine, turn off water supply, point gun in a safe direction, and squeeze trigger to relieve trapped pressure, and let engine cool.
WARNING
The high pressure stream of water that this equipment produces can cut through skin and its underlying tissues, leading to serious injury and possible amputation.
Spray gun traps high water pressure, even when engine is stopped and water is disconnected, which can cause injury.
•Keep high pressure hose connected to pump and spray gun while system is pressurized.
•ALWAYS point spray gun in safe direction and squeeze spray gun trigger, to release high pressure, every time you stop engine. Engage trigger lock when not in use.
3.Disconnect hose from spray gun and high pressure outlet on pump. Drain water from hose, spray gun, and nozzle extension. Use a rag to wipe off the hose.
4.Empty pump of all pumped liquids by pulling recoil handle about six times. This should remove most liquid in pump.
5.Store unit in a clean, dry area.
6.If storing for more than 30 days, see Long Term Storage on next page.
