Air Cooling System
Over time debris may accumulate in cylinder cooling fins and
cannot be observed without partial engine disassembly. For
this reason, we recommend you have a qualified service
dealer clean the cooling system per recommended intervals
(see Maintenance Schedule in beginning of Maintenance
section). Equally important is to keep top of engine free from
debris. See Clean Debris.
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. 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.
2. 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.
3. Place the spray gun, nozzle extension, ProjectPro®
nozzles and high pressure hose in the accessory tray.
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.

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.
Keep areas within heavy line clear of debris.
