HOW TO USE YOUR

PRESSURE WASH ER

If you haveanyproblems operating your pressurewasher,

pleasecall the pressure washer helpline at 1-800-270-1408.

To Start Your Pressure Washer

To start your pressure washer for the first time, follow
these instructions step-by-step. This starting information
also applies if you havelet the pressure washer sit idle for
at least a day.

• Placethe pressure washer in anarea close enoughto an
outside water source capable of supplying water at a flow

rate greater than 2.8gallons per minute.

• Check that the highpressure hose is connected to the
spray gun andto the pump. See"Preparing Pressure

Washer for Use" for illustrations.

• Make sure unit is in a level position.

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

CAUTION! Do Not run the pump without the water
supply connected and turned on. You must follow this
caution or the pump will be damaged.

• Squeezethe trigger on the gun until you havea steady
stream of water. This purges the pump of air and

impurities.

• Attach the nozzle extension to the spray gun (Figure I I).
Tighten by hand.

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

"On" position

• Move the throttle leverto "Fast" position, shown on
engine asa rabbit (Figure 14).

• Move the choke leverto the "Choke" position
(Figure 15).

/

fl

NOTE: For a warm engine,be sure the choke lever is in

the "Run" position.

• Grasp the unit's handle with your left hand. Pull the
starter grip lightlywith your right hand until you feel
some resistance, then pull briskly.

• Return the starter grip handle slowly. Do Not let rope
"snap back" against starter.

• When engine starts, slowly move choke lever to the
"Run" position. If enginefalters, move choke lever to
the "Choke" position, then to the "Run" position.

• If engine fails to start after six pulls, move choke lever to
the "Run" position. If enginefires, but does not continue

to run, move choke lever to the "Choke" position, then
to the "Run" position.

NOTE: If the recoil starter is hard to pull, it may be
necessary to squeezethe gun trigger to relieve internal
pump pressure.

How to Stop Your Pressure Washer

• Move throttle lever to "Stop" position.

• Turn the fuel shut-offvalveto the "Off' position (fully

clockwise).

• Squeeze trigger on the spray gun to relieve

pressure in the hose.

NOTE: A small amount of water will squirt out when you

releasethe pressure.

How to Use Accessory Tray

The unit isequipped with an accessory tray with placesto
store your nozzle extension and quick connect nozzles, and
slots to hold the cleaning solution bottle and the detergent
siphoning filter. There are also two hooks at the ends of
the handle to hold your spraygun and high pressure hose.

NOTE: The extra holes in the tray are for storing a brush
and a turbo wand. The brush and turbo wand are NOT

includedwith your pressure washer.You can buy these
items as optional accessories.

• Placethe nozzleextension through the holeon the
accessorytray, as shown in Figure16.

• Hangyour chemicalsolution bottle on the "J" hook and
placethe detergent siphoning filter in the lastslot on the

left (Figure 16).

• Placethe spraygun on the hook attached to the
accessorytray on the right side of the unit (Figure 16).

• Hangthe high pressure hose on the hook attached to
the accessorytray on the left side of the unitas shown
on page4.

How to Use the Nozzles

_iL CAUTION! Never exchange nozzleswithout

lockingthe safety latch on the trigger.

The quick-connect on the nozzle extension allows you to
switch between five different nozzles.The nozzles vary the
spray pattern asshown below (Figure 17).

Follow these instructions to change nozzles:

• Engagethe safetylatch on the spray gun.

•Putl back the collar on the quick-connect and pull the
current nozzle off. Store the nozzle in the space

provided on the handles storage panel.

NOTE: For a more gentle rinse, select the white 40° or

green 25° nozzle. To scour the surface, select the yellow

15° or red 0° nozzle. To apply chemical, select the black

nozzle.

• Putl back on the collar,insertthe new nozzle and release
the collar. Tugon the nozzle to make sure it issecurely

in place.

• For most effective cleaning,keep the spray nozzle
between 8 to 24 inchesaway from the cleaningsurface. If
you get the spray nozzle too close, you may damagethe

cleaningsurface.

Cleaning and Applying Chemical

CAUTION! You must attach all hoses before you

start the engine. Starting the enginewithout all 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 useof the nozzles.

• Prepare the detergent solution as required by the
manufacturer.

• Hangthe detergent solution on the "J" hook attached to

the accessory tray, asshown in Figure 18.

• Placethe smallfilter 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 black nozzle is installed.
NOTE: Detergent cannot be applied with the high

pressure nozzles (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 soakin 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 flushthe 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

A ARNING! Be extremely careful if you must

usethe pressure washer from a ladder, scaffolding

or any other relatively unstable location.Hose
water pressure builds asyou climb. When you press
the trigger, the recoil from the initialspray canbe
very strong. The high pressure spraycould cause
you to fall ifyou are too close to the cleaning

surface.

Wash and Rinse Surface

This pressure washer permits regulation of output water

pressure by varying the engine speed and by turning the

pressure control knob on the pump. The Pressure
Command TM lever found on the front of the engine may be
set, asshown in Figure 19:

Pressure Low to High
Duty Light Medium Heavy

Application Auto Concrete Paint removal

Boat Driveway Degreasing
Furniture Deck

• Increaseor decrease spray pressure by turning the
pressure control knob counterclockwise or clockwise
respectively (Figure 20).

After you have applied detergent, scour the surface
and rinse it clean as follows:

• Apply safety latch to spray gun.

• Remove the black chemical nozzle from the nozzle

extension.

• Select andinstallthe desired high pressurenozzle

following the instructions"How to Use the Nozzles" on

page 10.

• Keepthe spray gun a safedistance from the areayou
plan to spray.

• Adjust PressureCommandTM lever and pressure control
knob to obtain desired water pressure.

• Apply a high pressure spray to a small area and then

check the surface for damage.If no damageisfound, 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°E At this temperature, the system
engagesand cools the pump by discharging the warm
water onto the ground. This system prevents internal
damageto the pump.
