HOW TO USE YOUR
PRESSURE WASHER
If you have any proble s operating your pressure
washer, please call the pressure washer helpline at
18002701408.
You have asse bled 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 ti e is to follow these instructions
stepbystep. This starting infor ation 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 gallons per inute. 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 ore
than 50' of garden hose is needed.
 Check that the high pressure hose is tightly
connected to the spray gun and to the pu p. See
ASSEMBLY section for illustrations.
 Connect the garden hose to water inlet on the
pressure washer pu p and turn the water on all
the way.
IMPORTANT: Do not run pu p without the water
supply connected and turned on. You ust follow this
caution or the pu p will be da aged.
 Move the Throttle Control Lever to the Fast
position
 Set Choke Lever to Choke position.
Note: This is a ultiposition choke.
Note: For a war engine, be sure the Throttle
Control Lever is in the Fast position and the Choke
Lever is in the Run position.
 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 strea . Continue to
hold trigger until you have a steady strea of water
and no air re ains.This will ake it easier to pull
start the engine. Release the trigger.
 Apply the safety latch to the spray gun trigger
(Figure 10).
 Grasp rope handle and pull slowly until you feel
so e resistance. Then pull cord rapidly to
overco e co pression, 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 ove the Choke
Lever fro 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,
ove 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.
 Si ply shutting off the engine will not release
pressure in the syste . Squeeze trigger on the
spray gun to relieve pressure in the hose.
Note: A s all a ount 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.
