HOW TO USE YOUR
PRESSURE WASHER
If you have any problems operating your pressure
washer, please call the pressure washer helpline at
1-800-2 0-1408.
How to Start Your Engine
The best way to start your engine-powere pressure
washer for the first time is to follow these instructions
step-by-step. This starting information also applies
whenever you start the engine after you have let the
pressure washer sit i le for at least a ay.
 This pressure washer requires a water source that
flows at least 2.5 gallons per minute. Do not attempt
to siphon water from a non-pressurize container.
Place the pressure washer close enough to an
outsi e water source so that no more than 50' of
gar en hose is nee e .
 Check that the high pressure hose is tightly
connecte to the spray gun an to the pump. See
ASSEMBLY section for illustrations.
 Connect the gar en hose to water inlet on the
pressure washer pump an turn the water valve on
all the way.
IMPORTANT: Do not run pump without the water
supply connecte an turne on. You must follow this
caution or the pump will be amage .
 Place the Run/Stop switch to Run.
 Press the primer bulb 3 times, waiting 2 secon s
between each push
Note: For a warm engine, o not prime.
 Squeeze the trigger on the spray gun to relieve air
pressure cause by turning on the water. Water will
spew out the gun in a thin stream. Continue to hol
trigger until you have a stea y stream of water an
no air remains.This will make it easier to pull start
the engine. Release the trigger.
 Apply the safety latch to the spray gun trigger
(Figure 11).
 Grasp rope han le an pull slowly until you feel
some resistance. Then pull cor rapi ly to
overcome compression, prevent kickback an start
the engine. Let rope return to starter slowly.
If after 3 pulls the engine fails to start, isengage the
spray gun safety latch, squeeze the trigger to relieve
water pressure, re-engage the spray gun safety latch
an pull the recoil starter han le rapi ly (Max. 3
pulls).
How to Stop Your Pressure
Washer
 Move the Run/Stop switch to Stop.
 Simply shutting off the engine will not release
pressure in the system. Squeeze trigger on the
spray gun to relieve pressure in the hose.
Note: A small amount of water will squirt out when
you release the pressure.
