HOW TO USEYOUR

PRESSURE WASH ER

If you haveanyproblems operating your pressurewasher,

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 have let 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 and to the pump. See"Preparing Pressure

Washer for Use" for illustrations.

• Makesure unit isin a level position.

• Connect the garden hose to the water inleton the
pressure washer pump.Turn ON the water.

SafetyLatch

• Rotate the fuel shut-off valve to the "On" position (fully
counter-clockwise) (Figure 13).

• Move the variable pressure control lever to "High"
position, shown on engineas a rabbit (Figure 14).

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 havea steady

"Choke" position, then to the "Run" position.

• Ifengine fails to start after six pulls,move choke leverto
the "Run" position. Ifengine fires, but does not continue
to run, move choke leverto the "Run" position.

NOTE: If the recoil starter ishard to pull, it may be
necessary to squeezethe guntrigger to relieve internal
pump pressure.

How to Use Accessory Tray

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 spray tips 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,keepthe 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 engine without 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.

• Preparethe 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.

• Makesure the blackspray tip is installed.
NOTE: Detergent cannot be applied with the high

pressure spray tips (White, Green,Yellow, or Red).

• Makesure 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.Reapplyas needed 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 placingthe filter into a bucket of
clean water, then run the pressure washer in low pressure

for I-2 minutes.

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.

• Keepthe spray gun a safedistance from the area you

plan to spray.

• Adjust the spraypressure by slidingthe variablepressure
contol lever left or right, as shown in Figure 14on page8.

_ AUTION! Firmly grasp spray gun with both

handswhen usinghigh pressure spray to avoid
injury if gun kicks back.

• Apply a high pressure spray to a small area and then
check the surface for damage.If no damage is found, you
can assume it is okay to continue rinsing.

• Start at the top of the areato be rinsed, working down
with same overlapping strokes as you usedfor cleaning.

Pressure Washer Rinsing

_ ARNING! Beextremely careful if you must use

the pressure washer 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 closeto 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:

Pressure Low to High
Duty Light Medium Heavy

Application Auto Concrete Paint removal

Boat Driveway Degreasing
Furniture Deck

Automatic Cool Down System

(Thermal Relief)

If you run the engine on 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.
