OPERATING
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. Flush detergent siphoning tube by placing the filter into a
pail of clean water while running pressure washer in low
pressure mode. Flush for one to two minutes.
2. Shut off engine, turn off water supply, point gun in a safe
direction, press red button and squeeze trigger to relieve
trapped pressure, and let engine cool.
3. Disconnect hose from spray gun and high pressure outlet
on pump. Drain water from hose, gun, and nozzle
extension. Use a rag to wipe off the hose.
4. Place the spray gun, nozzle extension, spray tips and high
pressure hose on the handle.
5. Empty pump of all pumped liquids by pulling recoil handle
about six times. This should remove most liquid in pump.
6. Store unit in a clean, dry area.
7. If storing for more than 30 days, see Long Term Storage.
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, press red button and
squeeze spray gun trigger, to release high pressure, every time you
stop engine.
WARNING
Fuel and its vapors are extremely flammable and
explosive.
Fire or explosion can cause severe burns or death.
WHEN STORING FUEL OR EQUIPMENT WITH FUEL IN TANK
• Store away from furnaces, stoves, water heaters, clothes dryers, or
other appliances that have pilot light or other ignition source because
they can ignite fuel vapors.
