HOW TO USE YOUR PRESSURE

WASHER

If you have any problems operating your pressure

washer, please call the pressure washer helpline at

1-800-222-3136.

To Start Your Pressure Washer

To start your engine-powered pressure washer for the
first time, follow these instructions step-by-step. This
starting information also applies whenever you start
the engine after you have let the pressure washer sit

idle for at least a day.

• Place the pressure washer in an area close
enough to an outside water source capable of
supplying water at a flow rate greater than

2.4 gallons per minute.

• Check that the high pressure hose is tightly
connected to the spray gun and to the pump. See
"Assembling Your Pressure Washer" (page 6) for

illustrations.

• Make sure 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 and turned on. You

must follow this caution or the pump will be

damaged.

• Squeeze trigger on gun to purge pump system of
air and impurities.

• Attach nozzle extension to spray gun. Tighten by

hand.

• Position the nozzle in the low pressure mode (slide

nozzle forward) and squeeze the trigger on the
spray gun to relieve pressure caused by turning
ON the water. Water will flow out of the gun in a
thin stream. Continue to hold trigger until there is a
steady stream of water and no air remains in the
system. Release the trigger.

• Engage the safety latch to the spray gun trigger.

Safety Latch

\

If the choke lever was placed in the "Closed"
position to start the engine, move it slowly to the

"Open" position as the engine warms up enough to
run smoothly.

How to Stop Your Pressure Washer

• Move throttle lever to "Stop" position.

• Rotate the fuel valve lever to the "Off" position.

• Squeeze trigger on the spray gun to relieve

pressure in the hose.

NOTE: A small amount of water will squirt out when

you release the pressure.

How To Use the Adjustable Nozzle

You now should know how to START your pressure
washer and how to STOP it. The information in this

section will tell you how to adjust the spray pattern
and apply detergent or other cleaning chemicals.

_ DANGER! Never adjust spray pattern when

spraying. Never put hands in front of nozzle to

adjust spray pattern.

On the end of your spray gun is a nozzle handle that
you can slide forward and backward to adjust the
spray pattern to be either high or low pressure.

Slide nozzle backward for
high pressure mode.

You can also adjust the spray so it is concentrated in
a stream pattern or expanded into a fan pattern by
twisting it.

Slide nozzle forward for
low pressure mode and
detergent application.

• Twisting the nozzle adjusts the spray pattern from
a narrow pattern to a fan pattern.

• For most effective cleaning, keep the spray nozzle
between 8 to 24 inches away from cleaning
surface.

• If you get the spray nozzle too close, especially
using high pressure mode, you may damage the

surface being cleaned.

• Do Not get closer than 8 inches when cleaning
tires.

Applying Detergent with the Adjustable
Nozzle

IMPORTANT: Use chemicals designed specifically
for 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.

To apply detergent, follow these steps:

• Review the use of the adjustable nozzle.

• Prepare the detergent solution as required by the

job.

• Hang the detergent solution container on the hook
of the wireform attached to the handle.

• Place the filter end of the detergent siphoning tube
into the detergent container.

q

Twist nozzle counter-
clockwise for fan pattern.

• Point the nozzle toward the ground, disengage the
safety latch, and press the trigger to test the

pattern.

Twist nozzle clockwise for

narrow spray pattern.

_ AUTION: When inserting the filter into the

detergent container, route the tube so as to keep it
from inadvertently contacting the hot muffler.

• Slide the adjustable nozzle forward to low pressure
mode. Detergent cannot be applied with the nozzle
in high pressure position.

• Make sure the garden hose is connected to the
water inlet. Check that the high pressure hose is
connected to the spray gun and the pump. Start
the engine.

• Apply detergent to a dry surface, starting from the
bottom and working up.

• Allow the detergent to "soak in" for 3-5 minutes
before rinsing.

• For washing, start at lower portion of area to be
washed and work upward, using long, even,
overlapping strokes.

Pressure Washer Rinsing

_ ARNING: Be extremely careful if you use the

pressure washer from a ladder, scaffolding or

any other relatively unstable location. Pressure

in a running washer builds as you climb. When
you press the trigger, the recoil from the initial
spray could force you to fall. The high pressure
spray could also force you to fall if you are too
close to the cleaning surface.

ForRinsing:

• Slidethenozzlebackwardtohighpressure,press

Automatic Cool Down System

(Thermal Relief)

If you run the engine on your pressure washer for
3-5 minutes without pressing the trigger on the spray
gun, circulating water in the pump can reach
temperatures between 140-145°F. The automatic cool
down system engages at this temperature and cools
the pump by discharging the warm water onto the
ground, preventing internal pump damage.

How to Use the Hose Reel

Your pressure washer is equipped with a hose reel
that is designed to store your hose when unit is not in

use. These instructions are for short term storage
only. For long term storage see "Storage" on page 15.

After each use:

• Disconnect hose from gun and high pressure outlet
on pump.

• Drain water from hose.

• Slide one end of the hose into the hole on the hose
reel. Turn the hose reel with the handle to coil the
hose onto the reel.

• Push the other end of the hose into the clip on the
side of your unit.

IMPORTANT: Do Not use your pressure washer with
the hose coiled onto the hose reel. The hose reel is for

storage purposes only.

• Purge pump of air and contaminants.

PRESSURE WASHER
MAINTENANCE

Check and Clean Inlet Screen

Examine garden hose inlet screen. Clean if it is
clogged or replace if it is torn.

Check High Pressure Hose

High pressure hoses can develop leaks from wear,
kinking, or abuse. Inspect hose before each use.
Check for cuts, leaks, abrasions, bulging of cover, or
damage or movement of couplings. If any of these
conditions exist, replace hose immediately.

_ ANGER: Never repair a high pressure hose.

Replace with hose that meets the minimum
pressure rating of your pressure washer.

Check Gun and Nozzle Extension

Examine hose connection to gun and make sure it is

secure. Test trigger by pressing it and making sure it
springs back into place when you release it. Engage
safety latch and test trigger. You should not be able to
press trigger. Replace gun immediately if it fails any of

these tests.

Check In-Line Filter

Refer to the illustrationand service the in-line filter if it
becomes clogged, as follows:

In-line Filter

Nozzle extension

O-ring

.

Detach gun and nozzle extension from high
pressure hose. Detach nozzle extension from gun
and remove o-ring and screen from nozzle
extension. Flush the screen, gun, and nozzle

extension with clean water to clear debris.

.

If the screen is damaged, the o-ring kit contains a
replacement in-line filter screen and an o-ring. If
undamaged, reuse screen.

.

Place the in-line filter screen into the threaded end
of the nozzle extension. Direction does not matter.

Push the screen in with the eraser end of a pencil
until it rests flat at the bottom of the opening. Take

care to not bend the screen.

4. Place the o-ring into the recess. Push the o-ring
snugly against the in-line filter screen.

5. Assemble the nozzle extension to the spray gun,
as described earlier in this manual.

Purge Pump of Air and Contaminants

To remove the air from the pump, follow these steps:

• Set up the pressure washer as described in the

ASSEMBLY section and connect the water supply.

• Remove the nozzle extension extension from the

gun.

• Pull the trigger on the gun and hold until a steady

stream of water appears.

To remove the contaminants from the pump, follow
these steps:

• Set up the pressure washer as described in the

ASSEMBLY section, and connect the water supply.

• Remove the nozzle extension from the gun.

• Start the engine according to instructions in

OPERATION section.

• Pull the trigger on the gun and hold.

engage the safety latch and refasten the nozzle
extension.

Nozzle Maintenance

If the nozzle becomes restricted or clogged with
foreign materials such as dirt, excessive pump
pressure may develop. A partially clogged nozzle can
cause a pulsing condition during use. This generally is
not a pump related problem, but rather a clogged or
partially restricted nozzle.

If the nozzle becomes clogged or partially restricted,
immediately clean the nozzle with the kit included with
your pressure washer by following these instructions:

• Shut off the engine and turn off the water supply.

• Separate the nozzle extension from the gun.

• Rotate to stream setting.

• Remove nozzle from the end of the nozzle

extension using a 2 mm or 5/64 allen wrench.

• Tip your pressure washer to drain oil from the oil
dipstick into a suitable container. When crankcase
is empty, return the pressure washer to upright
position. Wipe up spilled oil.

• Slowly pour oil into oil fill opening until oil reaches
"UPPER LIMIT" mark on the dipstick. Stop
occasionally to check oil level.

• If the oil level is near or below the lower limit mark
on the dipstick, fill with the recommended oil to the

upper limit mark. DO NOT OVERFILL.

• Install oil dipstick, hand tighten securely.

• Wipe up any remaining oil.

Service Air Cleaner

Your engine will not run properly and may be
damaged if you run itwith a dirty air cleaner.

Replace the air cleaner once every 200 hours of
operation or once each year, whichever comes first.
Replace more often if operating under dirty or dusty

conditions. Replacements are available at your local
Sears service center.

To replace the air cleaner, follow these steps:

• Press the latch tabs on the top of the air cleaner
cover, and remove the cover.

AIR CLEANER BODY

• Check electrode gap with wire feeler gauge and set
gap at 0.028 inches-0.031 inches
(0.70mm-0.80mm), if necessary.

• Install spark plug, tighten securely.

Carburetor

If you think your carburetor needs adjusting, see your
nearest Sears service center. Engine performance
may be affected at altitudes above 4000 feet. For
operation at higher elevations, contact your nearest

Sears service center.

Spark Arrester Service

Your engine is not factory-equipped with a spark
arrester. In some areas, it is illegal to operate an
engine without a spark arrester. Check local laws and
regulations. A spark arrestor is available from your

nearest Sears service center.
The spark arrester must be serviced every 100 hours

to keep it functioning as designed.

If the engine has been running, the muffler will be very
hot. Allow the muffler to cool before servicing the
spark arrestor.

• Remove the three 6 mm bolts from the muffler

protector, and remove the muffler protector.

SPARK ARRESTER

• Remove dirty air filter element carefully to prevent
debris from falling into carburetor. Discard.

• Clean inside of filter case, using a moist rag.

• Reinstall new air filter element and cover.

Clean / Replace Spark Plug

Check and clean the spark plug every 100 hours of
operation. Replace the spark plug yearly or every

200 hours of operation.

,_ CAUTION: Disconnect spark plug wire from

spark plug and keep wire away from spark plug

while servicing engine.

• Clean area around spark plug.

• Remove and inspect spark plug.

• Replace spark plug if the electrodes are worn, or if
the insulator is cracked or chipped. For
replacement use BPR6ES (NGK) or equivalent.

MUFFLER PROTECTOR

/J

SPECIAL SCREWS

6 mm BOLTS

MUFFLER

• Remove the two special screws from the spark
arrester, and remove the spark arrester from the

muffler.

• Use a brush to remove carbon deposits from the
spark arrester screen. Be careful to avoid
damaging the screen. The spark arrester must be
free of breaks and holes. Replace the spark
arrester if it is damaged.

• Install the spark arrester and muffler protector in
the reverse order of disassembly.

AFTER EACH USE

Water should not remain in the unit for long periods of

time. Sediments or minerals can deposit on pump

parts and "freeze" pump action. Follow these
procedures after every use:

• Flush detergent siphoning tube by placing the filter
into a pail of clean water while running pressure

washer in low pressure mode (adjustable nozzle in
the forward position). Flush for one to two minutes.

• Shut off the engine and let it cool, then remove all
hoses.

• Disconnect spark plug wire from spark plug.

• Empty the pump of all liquids by pulling recoil
handle about 6 times. This should remove most of

the liquid in the pump.

• Coil the high pressure hose and inspect it for

damage. Cuts in the hose or fraying could result in

leaks and loss of pressure. Should any damage be

found, replace the hose. Do Not attempt to repair a
damaged hose. Replace the hose with the genuine

Craftsman part.

• Disconnect hose from gun and high pressure outlet

on pump. Drain water from hose and wipe off the

hose with a rag.

• Slide one end of the hose into the hole on the hose

reel. Turn the hose reel with the handle to coil the

hose onto the reel. Push the other end of the hose
into the clip on the side of you unit.

• Reconnect spark plug wire to spark plug.

• Store unit in a clean, dry area.

_ ANGER: Never store the engine with fuel in

the gas tank indoors or in enclosed, poorly
ventilated areas where fumes may reach an
open flame, a spark, or pilot light.

WINTER STORAGE

_ AUTION: You must protect your unit from

freezing temperatures. Failure to do so will

permanently damage your pump and render

your unit inoperable.

To protect the unit from freezing temperatures:

• Flush detergent siphoning tube by placing the filter
into a pail of clean water while running pressure

washer in low pressure mode (adjustable nozzle in
the forward position). Flush for one to two minutes.

• Disconnect hose connected to chemical inject

fitting on the pump.

• Empty the pump of all pumped liquids by pulling

recoil handle about 6 times. This should remove

most of the liquid in the pump.

• Connect a 3-foot section of garden hose to the

water inlet adapter. Pour RV-antifreeze (antifreeze
without alcohol) into the hose. Pull the recoil handle

twice. Disconnect 3-foot hose.

LONG TERM STORAGE

If you do not plan to use the pressure washer for more

than 30 days, you must prepare the engine for long
term storage.

It is important to prevent gum deposits from forming in
essential fuel system parts such as the carburetor, fuel
filter, fuel hose or tank during storage. Also,
experience indicates that alcohol-blended fuels (called
gasohol, ethanol 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.

Protect Fuel System

Fuel Stabilizer:
If adding a fuel stabilizer, fill the fuel tank with fresh

gasoline. If only partially filled, air in the tank will
promote fuel deterioration during storage.

• Add fuel stabilizer following manufacturer's
instructions.

• Make sure you have water supply to pump inlet
connected and turned ON.

• Run the engine outdoors for 10 minutes to be sure
that treated gasoline has replaced the untreated
gasoline in the carburetor.

Change Oil

While engine is still warm, drain oil from crankcase.
Refill with recommended grade. See "Changing Oil" on
page 13.

Oil Cylinder Bore

• Remove spark plug. Squirt about 1 tablespoon of
clean engine oil into the cylinder. Cover spark plug
hole with rag. Pull recoil handle slowly to distribute
oil. Avoid spray from spark plug hole.

• Install spark plug. Do Not connect spark plug wire.

OTHER

• Do Not store gasoline from one season to another.

• If possible, store your unit indoors and cover it to
give protection from dust and dirt. BE SURE TO

EMPTY THE FUEL TANK.

Draining Fuel Tank:

_ ANGER: Drain fuel, using a funnel, into

approved container outdoors, away from open
flame. Be sure engine is cool. Do Not smoke.

• Remove the float bowl bolt, then rotate the fuel
valve lever to the "ON" position.

• After all fuel has drained into the container, reinstall
the float bowl bolt while holding the float bowl in

position on the carburetor. Tighten bolt securely.

IMPORTANT: NEVER cover your pressure washer
while engine and exhaust area are warm.
