Purge air from the water supply hose by squeezing the trigger until a
steady stream of water flows out of the nozzle at low pressure. (Air in
the hoses can cause damage to the pump, so always make sure all the air
is out of the hoses before starting the pressure washer engine.)
Make sure the water supply hose is not kinked. A kinked hose will
provide insufficient water supply to the pump and reduce its life. Make
sure the hose remains unkinked after moving the pressure washer.
If using water feed tank:
Ensure that the tank feed ball valve is OPEN, and the city tap water ball
valve is CLOSED. (The ball valve you are not using must be closed
before starting the engine or pump cavitation could occur.)
Make sure the supply hose from the tank is not kinked. A kinked hose
will provide insufficient water supply to the pump and reduce its life.

Start engine
Start the engine to power the pump.
1. Make sure water supply is connected and primed.
CAUTION: Running the pump dry will cause damage and void the
warranty.
2. To prevent accidental spraying, engage the safety latch on spray gun
trigger by rotating it to the locked position.
3. Follow the instructions in the Engine Manual for starting the engine.
- If the engine doesn't start on the first try, pressure may build up in
the pump. Relieve pressure by squeezing the spray gun trigger
before attempting to start engine again. This will make starting
easier.
DANGER:
Do not inhale engine exhaust. It contains dangerous carbon monoxide
that can kill you.
Apply cleaning
chemical
(if desired)
If desired, spray cleaning chemical at low pressure (with or without
heated water).
1. Make sure the chemical injector is properly set up according to the
instructions in Step 2, "Set Up for Chemical Spraying".
2. Make sure the low pressure BLACK nozzle is attached before
beginning to spray chemicals -- Only the low pressure black nozzle will
allow chemicals to be drawn through the chemical injector into the
water stream.
