HOW TO USE YOUR

PRESSURE WASH ER

If you haveanyproblems operating your pressurewasher,

pleasecatl 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 instructionsstep-by-step.This starting information
also applies ifyou havelet the pressurewasher sit idle for
at leasta day.

• Placethe pressure washer in an area close enough to an
outside water source capable of supplying water at a flow

rate greater than 2.8gallons per minute.

• Check that the high pressure hose isconnected to the
spray gun andto the pump. See"Preparing Pressure

Washer for Use" for illustrations.

• Make sure unit is in a level position.

• Grasp starter grip and pull slowly until you feel some
resistance.Then pull cord out with rapid full arm stroke.
Let rope return slowly. Do Not let rope "snap back"
againststarter.

• If the enginefails to start repeat above steps or refer to
the engine owner's manual.

• If the choke was pulled to the CLOSED position to start
the engine, slowly push it to the OPEN position as the
engine runs smoother.

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

How to use Accessory Tray

The unit is equipped with an accessory tray with placesto
store your nozzle extension and quick connect nozzles,and
slots to hold the cleaningsolution bottle and the detergent
siphoning filter. There are also two hooks at the ends of
the handle to hold your spray gun 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

included with your pressure washer. You can buy these

items as optional accessories.

• Placethe nozzle extension through the hole on the
accessory tray, asshown in Figure 16.

How to Stop Pressure Washer

• Move Throttle Control lever to the 'Stop' position.

• Simply shutting off the enginewill 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
squeezethe trigger.

/

• Hang your chemical solution bottle on the "J"hook and
place the detergent siphoning filter inthe lastslot on the

left (Figure 16).

• Placethe spray gun on the hook attached to the
accessory tray on the right side of the unit (Figure 16).

• Hang the high pressure hose on the hook attached to
the accessory tray on the left side of the unit asshown
on page4.

How to Use the Nozzles

_ AUTION! 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 nozzlesvary the
spray pattern as shown below (Figure 17).

Follow these instructions to change nozzles:

• Engagethe safety latch on the spray gun.

• Pull 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.

• Pull back on the collar,insertthe new nozzle and release
the collar.Tugon the nozzle to make sure it is securely

in place.

• For most effective cleaning, keepthe spraynozzle
between 8 to 24 inchesawayfrom 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 engine without all the hoses
connected andwithout the water turned ON willdamage

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 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 blacknozzle 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 highpressure hose is connected to

the spraygun andthe pump and start the engine.

• Apply the detergent to a dry surface, starting at lower
portion of area to be washed andwork 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 abucket of
clean water, then run the pressure washer in low pressure

for I-2 minutes.

• Remove the black chemical nozzle from the nozzle
extension.

• Select and installthe desired high pressure nozzle
following the instructions "How to Use the Nozzles" on

page 10.

• Keep the spray gun a safedistance from the area you

plan to spray.

• Apply ahigh pressure spray to a small area and then
check the surface for damage.If no damageis found, you
can assumeit isokay to continue rinsing.

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

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°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.

Pressure Washer Rinsing

_ ARNING! Be extremely careful if you must

use the pressure washer from a ladder,scaffolding
or anyother relatively unstable location. Hose
water pressure builds as you climb. When you press
the trigger, the recoil from the initial spraycanbe
very strong. The high pressure spray could cause
you to fall if you are too close to the cleaning

surface.

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

• Apply safetylatchto spray gun.
