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

The best way to start your engine-powered pressure

washer for the first time is to 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

2.2 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 5) 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.

_ AUTION: 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.

• Choose the nozzle you want to use and insert it

into the nozzle extension. See "How to Use the

Nozzles".

• Move the choke knob to the "Choke" position.

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

in the "Run" position.

• Engage the safety latch to the spray gun trigger.

Latch

Move throttle lever to "Fast" position, shown here

as a rabbit.

• Pull the starter grip handle lightly until you feel

some resistance, then pull briskly.

• Return the starter grip handle slowly. Do Not let

rope "snap back" against starter.

• If the engine fails to start, disengage safety latch

and squeeze trigger on gun to release pump

pressure. Engage safety latch and repeat previous

two steps.

• If the choke knob was placed in the "Choke"

position to start the engine, move it slowly to the

"Run" position as the engine warms up enough to

run smoothly.

How to Stop Your Pressure Washer

• Move throttle lever on engine to "Stop" 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 Nozzles

_ DANGER! Never exchange nozzles without

locking the safety latch on the trigger.

The quick-connect on the nozzle extension allows you

to switch between four different nozzles. The nozzles

vary the spray pattern as shown below.

40°

White

Yellow

25°

ow Pressure

se to apply

chemical

_ Red

To change nozzles:

• Engage the 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 control panel.

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

nozzle. To scour the surface, select yellow 15° or red

0° nozzle. To apply chemical, select black low

pressure nozzle.

• Pull back on the collar, insert the new nozzle and

release the collar. Pull on the nozzle to make sure

it is securely in place.

• For most effective cleaning, keep the spray nozzle

between 8 to 24 inches away from the cleaning

surface. If you get the spray nozzle too close, you

may damage the cleaning surface.

Cleaning and Applying Chemical

_ ARNING! 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.

IMPORTANT: Use soaps designed specifically for

pressure washers. Household detergents could

damage the pump.

To apply detergent follow these steps:

• Review the use of the nozzles.

• Prepare the detergent solution as required by the

manufacturer.

• Hang the detergent solution container on the hook

at the rear of the pressure washer.

• Place the small filter of the chemical injection tube

into the detergent container.

_ AUTION! Keep the chemical injection tube

from coming in contact with the hot muffler. This

will damage the chemical injection tube. When

inserting the filter into a chemical bottle, route

the tube so as to keep it from inadvertently

contacting the hot muffler.

• Make sure the black nozzle is installed on the

nozzle extension.

NOTE: Detergent cannot be applied with the high

pressure nozzles (White, Yellow, or Red).

• Make sure the garden hose is connected to the

water inlet. Check that high pressure hose is

connected to spray gun and pump, then start

engine.

• Apply the detergent to a dry surface, starting at

lower portion of area to be washed and work

upward, using long, even, overlapping strokes. Do

Not allow the detergent to dry on. Allowing

detergent to dry on surface may cause streaking.

• Allow the detergent to soak between 3-5 minutes

before washing and rinsing. Reapply as needed to

prevent surface from drying.

Pressure Washer Rinsing

_ ARNING! Be extremely careful if you must

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.

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 and install the desired high pressure nozzle

following the instructions "How to Use the Nozzles"

on page 7.

• Keep the spray gun a safe distance from the area

you plan to spray.

• Apply a high pressure spray to an small area and

then check the surface for damage. If no damage

is found, you can assume it is okay to continue

cleaning.

• Start at the top of the area to be rinsed, working

down with same overlapping strokes used for

cleaning.

• The use of a brush may be helpful on some hard to

clean surfaces.

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 a

temperature between 140-145°F. When the water

reaches this temperature, the automatic cool down

system engages and cools the pump by discharging

the warm water onto the ground. This system prevents

internal damage to the pump. Once the pump has

cooled, it will stop discharging.

NOTE: This is not a leak. Do Not return the pressure

washer.

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. Put safety

latch in UP position 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:

1. Detach gun and lance from high pressure hose.

Detach lance from gun and remove o-ring and

screen from lance. Flush the screen, gun, and

lance with clean water to clear debris.

In-line Filter

Lance

O-ring

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 lance. 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

• Replace if screen is damaged.

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. 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 3 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.

• Drain water from hose and properly hang it on the

wire support provided.

• Reconnect spark plug wire to spark plug.

• Store unit in a clean, dry area.

,_ DANGER: 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

,_ CAUTION: 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. 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 3 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.

• Properly dispose of leftover antifreeze.

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 additive:

If adding a fuel additive, fill the fuel tank with fresh

gasoline. If only partially filled, air in the tank will

promote fuel deterioration during storage. Engine and

fuel can be stored up to 24 months with additive.

• Add fuel additive 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.

If fuel additive is not used, remove all fuel from tank

and run engine until it stops from lack of fuel.

Change Oil

While engine is still warm, not hot, drain oil from

crankcase. Refill with recommended grade. See

"Changing Oil" on page 11.

Oil Cylinder Bore

• Remove spark plug. Squirt about 1/2 ounce 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.

IMPORTANT: NEVER cover your pressure washer

while engine and exhaust area are warm.
