HOW TO USE YOUR
PRESSURE WASHER
If you have any problems operating your pressure
washer, please call the pressure washer helpline at
1-800-270-1408.
You have assembled your high pressure washer and
have prepared the engine for starting. You are now
ready to clean your car, boat or the outside of a
building or whatever you plan to clean.
How to Start Your Engine
The best way to start your enginepowered 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 idle for at least a day.
 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 pressurized
container. Place the pressure washer close
enough to an outside water source so that no more
than 50' of garden hose is needed.
 Check that the high pressure hose is tightly
connected to the spray gun and to the pump. See
ASSEMBLY section for illustrations.
 Connect the garden hose to water inlet on the
pressure washer pump and turn the water on all
the way.
IMPORTANT: Do not run 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 to relieve air
pressure caused by turning ON the water. Water
will spew out the gun in a thin stream. Continue to
hold trigger until you have a steady stream of water
and 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 10).
 Move the Throttle Control Lever to the Fast
position.
 Set Choke Lever to Choke position.
Note: This is a multiposition choke.
Note: For a warm engine, be sure the Throttle Control
Lever is in the Fast position and the Choke Lever is
in the Run position.
 Grasp rope handle and pull slowly until you feel
some resistance. Then pull cord rapidly to
overcome compression, prevent kickback and start
the engine. Let rope return to starter slowly.
Note: Always keep the Throttle Control Lever in the
Fast position when operating the pressure washer.
 When the engine starts, gradually move the Choke
Lever from one position to the next until it is in the
Run position.
If after 3 pulls the engine fails to start, disengage the
spray gun safety latch, squeeze the trigger to relive
water pressure, reengage the spray gun safety latch,
move the Choke Lever to the Run position and pull
the recoil starter handle rapidly (Max. 3 pulls).
How to Stop Your Pressure
Washer
 Move the Throttle Control Lever to the Slow position.
 Wait for the engine to idle down.
 Move the Throttle Lever Lever to the Stop position.
 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.
Figure 10  Squeeze trigger to relieve water pressure,
release trigger and turn the safety latch
ON.
