How To Use the Adjustable Nozzle

Cleaning W'dhThe Adjustable Nozzle

IMPORTANT: Use soaps designed specificallyfor
pressure washers. Household detergents could

damage the pump.
IMPORTANT: You must attach all hoses before you

start the engine. Starting the engine without all the

hoses connected and without the water turned ON will

damage the pump.

,_ WARNING: Never adjust spray pattern whenspraying. Never put hands infront ofthe nozzle

when adjusting the spray.

• Push the nozzle forward for low pressure. Pull the

nozzle backward to achieve high pressure.

Pull nozzle Push nozzle forward
backward for high for low pressure.

pressure.

• Twisting the nozzle adjusts the spray pattern from a
narrowto a "fan" pattern.

Twist nozzle

clockwise for
narrow spray.

• For mosteffective cleaning, keep spray nozzle

between 8 to 24 inches away from cleaning
surface.

• Ifyou get the spray nozzle too close, especially
usinghighpressure mode, you may damage the

surface being cleaned.

Twist nozzle

counterclockwise for
"fan" pattern.

To apply detergent follow these steps:

• Prepare the detergent solution as required bythe

job.

• Hang the detergent solution on the hook on the

handle.

Hang detergent
bottle on this

hook.

• Place small filteron the clear, chemical injection
tube into the detergent container.

• Push the adjustable nozzle forward to low pressure

mode. Detergent cannot be applied with nozzle
in high pressure position.

• Review the use of the adjustable nozzle.

• Connect garden hose to water inlet (see =TO

START PRESSURE WASHER" on page 8), check

that high pressure hose is connected to spray gun
and pump (see"ASSEMBLY on page 4), and start

engine.

Note: The first cleaning step is applying an

appropriate cleaning solutionto penetrate and loosen

gdme. Apply at low pressure. Leave the solutionon
surface for 3 to 5 minutes to allow solution to work.

Reapply as needed to prevent surface from drying.
Note." The second step is cleaning the surface you

have prepared with the pressure washer and then

dnsing it clean.

• For cleaning, start at lower portion of area to be

washed and work upward, using long, even
overlapping strokes.

Allow the detergent to soak inbetween 3-5 minutes
before washing and rinsing. Reapply as needed to

prevent surface from drying.

Rinsing W'dh the Pressure Washer

&WARNING: Be extremely careful if you mustuse the pressure washer from a ladder,

scaffolding or any other relatively unstable
location. When you pressthe trigger, the recoil

from the initialspray couldforce you to fall, or if
you are too close to the cleaning surface, high

pressure could force you off a climbing
appamtus.

• Hook up the water supply and start your pressure
washer (see TO START YOUR PRESSURE

WASHER on page 8).

• Pull adjustable nozzle backward for high pressure

mode. Wait for detergent to clear. Detergent will not
flow when in the high pressuremode.

• When detergent has cleared, you may want to

expand the spray pattern for a more gentle rinsing
action. Start at top of area to be rinsed, working

down with same action as for cleaning.

,_ CAUTION: Test a small area of the surface tobe cleaned. Make sure there is no damage

caused by the high pressure spray.

BEFORE STARTING THE PRESSURE

WASHER

_obe_etbe_giceyou_llneed_the_lowi_:

Add Engine Oil
Only use high quality detergent oil rated with API

service classification SF or SG. Select the oil's SAE
viscosity grade according to your expected operating

temperature:

colder _ 32°F _ warmer

5W30 SAE 30

Although multi-viscosityoils (5W30, 10W30, etc.)

improve starting in cold weather, these muifi-viscosity
oilswill result in increased oil consumptionwhen used

above 32°F, Check your engine oil level more
frequently to avoid possible damage from runninglow

on oil.

Place pressure washer on a level surface

• Clean area around oil fill and remove oildipstick.

Wipe dipstick clean.
Pour oilfrom enclosed bottle into the oilfill opening

until oil reaches full mark on the dipstick. Stop and
check the oil level periodically. Do not overfill.

Install oil dipstick, hand tighten securely.

Add Gasoline

• Use regular unleaded gasoline with the pressure
washer e.ngine. Fuel tank capacity is 1.5 U.S. quart.

,_ DANGER: Never fill fuel tank indoors.Never fillfuel tank when engine is running or hot. Do not

smoke when fillingfueltank.

,i_ CAUTION: Do not overfillthe fuel tank. Alwaysleave roomfor expansion.

,_ CAUTION: Experience indicates that alcohol

• blended fuels (called gasohol or usingethanol
or methanol) can attract moisture which leads to

separation and formation of acids during
storage. Acidic gas can damage the fuel system

of an engine while in storage.

To add fuel to engine:

• Clean area around fuel cap, remove cap.

• Add regular unleaded gasoline, slowly, to the fuel

tank.

Important: Never mix oil with gasoline.

• Install fuel cap e.nd wipe up any spilledgasoline.

TO START YOUR PRESSURE WASHER

• Place the pressure washer in an area close enough

to an outsidewater source that can flow at a rate of
at least 2 gallons per minute. Connect a garden

hose to the water spout.

• Check that the highpressure hose is tightly

connected to the spray gun and to the pump. See
ASSEMBLY section on page 4 for illustrations.

• Check inlet screen on the water inlet. If the screen

isdirty, clean before attaching a garden hose. If the

screen is damaged, do not connect to the garden

hose. Replace with screen provided in maintenance
kit or call 1-800-366-PART to order a replacement

inlet screen.

• Attach the the garden hose to the water inlet.

• Turn on the water.

A ARNING! Do not run pump without the watersupplyconnected and turned on. You must

follow this warning or the pump will be
damaged.

• Remove the adjustable nozzle extension from the

spray gun.

• Pull the triggeron the spray gun and hold until a

steady stream of water appears.

• Engage the safety latch on the spray gun.

• Attach adjustable nozzle extension onto spray gun.

• Move the throttlecontrol lever to the "Fast"

position.

\

Note: For a recently run engine, be sure the throttle

control is in the =Fast" positionand the choke is in the

=Run" position.

• Grasp rope handle and pull slowly until you feel

some resistance. Then pull cord rapidly to
overcome compression, 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 move the Choke
Lever from one position to the next until it isin the
"Run" position.

Note: If'after 3 pulls the engine fails to start, move the

Choke Lever to the 'Run' position, pull triggeron gun
to relieve pressure, reengage safety latch, and pull the

recoil starter handle rapidly (Max. 3 pulls).

HOW TO STOP YOUR PRESSURE
WASHER

• Move the Run/Stop Lever to the 'Stop' position.

• Simply shutting off the engine will not release

pressure in the system. Squeeze tdgger on the
spray gun to relieve pressure inthe hose.

Note: A small amount of water will squid out when
you release the pressure.

•SIPHONING

We recommend that you DO NOT siphon standing
water for your water supply. Contaminated, brackish or
dirty water can damage the pump. Connect only to

household water supply.

TIPS

• Never use the garden hose inlet to siphon
detergent or wax.

• If you have the spray nozzle tee far away, the
cleaning will not be as effective.
