HOW TO USEYOUR
PRESSURE WASH ER
If you haveany problems operating your pressure washer,
pleasecall the pressurewasher helpline at 1-800-270-1408.
To StartYour Pressure Washer
To start your pressure washer for the first time, follow
these instructions step-by-step.Thls starting information
also applies if you havelet the pressure washer sit idle for
at leasta day.
• Placethe pressure washer near an outside water source
capableof supplyingwater at a flow rate greater than
3.5gallons per minute and no lessthan 20 PSIat the
pressure washer end of the garden hose.
• Check that the high pressure hose is connected to the
spray gun andto the pump. See"Preparing Pressure
Washer for Use" for illustrations.
• Makesure unit is in a level position.
• Connect the garden hose to the water inlet on the
pressure washer pump.Turn ON the water.
CAUTION! DO NOT run the pump without the water
supply connected andturned on.You must follow this
caution or the pump will be damaged.
• Squeezethe trigger on the gun until you have a steady
stream of water.This purges the pump of air and
impurities.
• Attach the nozzle extension to the spraygun (Figure I I).
Tighten by hand.
Choose the spray tip you want to use and insert it into
the nozzle extension. See"How to Use the SprayTips"
on page 10.
• Engagethe safetylatch to the spraygun trigger (Figure 12).

"Choke" position, then to the "Run" position.
• Ifengine fails to start after six pulls,move choke leverto
the "Run" position. If engine fires, but does not continue
to run, move choke leverto the "Run" position.
NOTE: If the recoil starter is hard to pull, it may be
necessary to squeezethe guntrigger to relieve internal
pump pressure.
How to Stop Your Pressure Washer
• Movevariable pressure control lever to "Stop" position.
• Turn the fuel shut_offvalve to the "Off" position (fully

How to Use the SprayTips
_hL CAUTION! NEVERexchange spray tips without
lockingthe safety latch on the trigger.
The quick-connect on the nozzle extension allows you to
switch between five different spraytips.The spray tips vary
the spray pattern as shown below (Figure 17).
Follow these instructions to change spray tips:
• Engagethe safetylatch on the spray gun.
•Putl back the collar on the quick-connect and putl the
current spray tip off. Store the spraytips in the space
provided on the handlesstorage panel.
NOTE: For a more gentle rinse,select the white 40° or
green 25° spraytip.To scour the surface,select the yellow
15° or red 0° spraytip.To apply chemical,select the black
spray tip.
• Putlback on the collar,insert the new spray tip and
releasethe collar.Tugon the spraytip to make sure it is
securely inplace.
• For most effective cleaning,keep the spray tip from 8 to
24 inchesawayfrom the cleaningsurface.If you get the
spray tip too close, you maydamagethe cleaningsurface.
• DO NOT get closer than 6 incheswhen cleaningtires.
Cleaning and Applying Chemical
CAUTION! You must attach all hoses before you
start the engine.Starting the enginewithout alt the hoses
connected and without the water turned ON witldamage
the pump.
IMPORTANT: Use soaps designed specifically for
pressure washers. Household detergents could damage
the pump.
To apply detergent follow these steps:
• Reviewthe use of the spraytips.
• Prepare the detergent solution as required by the
manufacturer.
• Hangthe detergent solution on the "J"hook attached to
the accessory tray, as shown in Figure 18.

• Place the small filter end of the detergent siphoning tube
into the detergent container.
CAUTION! Keep the chemical injection tube from
coming in contact with the hot muffler.
• Make sure the blackspray tip is installed.
NOTE: Detergent cannot be applied with the high
pressure spray tips (White, Green,Yellow, or Red).
• Make sure the garden hose is connected to the water
inlet. Check that the high pressure hose is connected to
the spraygun and the pump and start the engine.
• Apply the detergent to adry surface, starting at lower
portion of area to be washed and work upward, using
long,even,overlapping strokes.
• Allow the detergent to soak in between 3-5 minutes
before washing and rinsing.Reapplyasneeded to prevent
surface from drying. DO NOT allow the detergent to
dry on (prevents streaking).
IMPORTANT: You must flush the chemical injection
system after each use by placing the filter into a bucket of
clean water, then run the pressure washer in low pressure
for I-2 minutes.
Pressure Washer Rinsing
_ ARNING! Be extremely careful if you must use
the pressurewasher from a ladder,scaffoldingor any
other relatively unstable location.When you press
the trigger,the recoil from the initial spray can be
very strong.The high pressure spray could causeyou
to fall if you are too close to the cleaningsurface.
Wash and Rinse Surface
This pressure washer permits regulation of output water
pressure byvarying the engine speed.The variable pressure
control lever found on the front of the engine maybe set,
as shown in Figure 19:
After you have applied detergent, scour the surface
and rinse it clean as follows:
• Apply safety latch to spray gun.
• Remove the black chemical spray tip from the nozzle
extension.
• Select and installthe desired high pressure spray tip
following the instructions "How to Use the SprayTips"
on page 10.
• Keep the spray gun asafedistance from the area you
plan to spray.
• Adjust the spraypressure by slidingthe variablepressure
contol lever left or right,asshown in Figure 14on page8.
_ AUTION! Firmly grasp spray gun with both
handswhen using high pressure spray to avoid
injury if gun kicks back.
• Apply a high pressure spray to a smallarea and then
check the surface for damage.If no damageis found, you
can assumeit isokay to continue rinsing.
• Start at the top of the areato be rinsed,working down
with same overlapping strokes asyou usedfor cleaning.
Automatic Cool Down System
(Thermal Relief)
If you run the engineon your pressure washer for
3-5 minutes without pressingthe trigger on the spray gun,
circulating water in the pump can reach a temperature
between 125°-155°EAt this temperature, the system
engagesand cools the pump by discharging the warm
water onto the ground. This system prevents internal
damageto the pump.
