How to Start Your Pressure Washer
To start your pressure washer for the first time, follow these instructions step-by-step. This starting
information also applies if you have let the pressure washer sit for more than 24 hours.
• Make sure unit is in a level position and that the gas and burner fuel tanks have adequate fuel.
• Caution: Do not mix gas and diesel fuel, keep in separate tanks as labeled.
• Check that the high pressure hose is tightly connected to the spray gun and to the pump.
• Check that the garden hose is connected to the water inlet on the pressure washer pump.
Turn the water on to maximum flow.
CAUTION! DO NOT run the pump without the water supply connected and turned on. You must follow
this caution or the pump will be damaged.
• Squeeze the trigger on the spray gun until you have a steady stream of water.
This purges the pump of air and debris.
• Apply the safety latch to the spray gun trigger.
• Start the engine according to the engine owner’s manual.
NOTE: If the recoil starter is hard to pull, release the safety latch, squeeze the spray gun trigger to
relieve internal pump pressure and reset the safety latch before attempting to start again.
WARNING! Motors are factory programmed and tested. Tampering of motor may void warranty.
How to Stop Your Pressure Washer
• Turn engine off according to the engine owner’s manual.
CAUTION: Shutting off the engine will not release pressure in the system. Point the gun away from
objects that can be damaged and squeeze trigger on the spray gun to relieve pressure in the hose.
CAUTION: Do not disconnect hose or gun under pressure. Before disconnecting discharge hose from
water outlet, turn burner off and open spray gun to allow water to cool below 100º before stopping the
machine. Then open the spray gun to relieve pressure. Failure to properly cool down or maintain the
heating coil may result in a steam explosion.
How to Use the Nozzles
CAUTION! NEVER exchange nozzles without locking the safety latch on the trigger (figure 2). The
quick–connect on the nozzle extension allows you to switch between several different nozzles. Each
nozzle provides a unique spray pattern and can work to better clean in different situations:
1) Engage the safety latch on the spray gun.
2) Pull back the collar on the quick–connect and pull the current nozzle off. Store the nozzle in the
space provided on the cart.
