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.
CAUTION! Before starting the pressure
washer, be sure you are wearing adequate eye protection.
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” 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.
Rotate the fuel valve lever to the “On“ position.
Move the choke lever to the “Closed” position.
NOTE: For a warm engine, be sure the choke lever is in the “Open” position.
Move the throttle lever to the “Fast” position, shown on the engine as a rabbit. Controls are shown in the desired operating condition.
As shown in the illustration to the right, ensure the nozzle extension is NOT attached to the spray gun. Note that your unit will appear slightly different from the illustration used here. Place the spray gun on the handle storage hook.
Place your left foot on the unit’s lower frame.
Grasp the spray gun with your left hand and squeeze the trigger on the spray gun. Water will flow out of the spray gun in a thin stream. Continue to squeeze the trigger. Your left hand will also serve to steady the unit.
Grasp the recoil starter handle with your right hand, as shown. Pull the starter 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 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.
With engine running, engage the safety latch to the spray gun trigger.
Attach nozzle extension to spray gun. Tighten by hand.

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 an adjustable nozzle that you can use to adjust the spray pattern and the spray pressure.
Slide the nozzle forward for low pressure spray; slide it backward for high pressure spray.
Point the nozzle towards a hard surface, disengage the safety latch, and press the trigger to test the pattern.
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 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.
CAUTION: 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. Reapply as needed to keep the surface wet.
Slide nozzle backward for high pressure mode.
Slide nozzle forward for low pressure mode and detergent application.
Twist nozzle counter­clockwise for fan pattern.
Twist nozzle clockwise for narrow spray pattern.
10
For washing, start at lower portion of area to be washed and work upward, using long, even, overlapping strokes.
Pressure Washer Rinsing
WARNING: 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 cause you to fall. The high pressure spray could also cause you to fall if you are too close to the cleaning surface.
For Rinsing:
Slide the nozzle backward to high pressure, press the trigger and wait for the detergent to clear.
NOTE: You can also stop detergent flow by removing detergent siphoning tube from container.
Keep the spray gun a safe distance from the area you plan to spray.
Apply a high pressure spray to a small area, then check the surface for damage. If no damage is found, it is okay to continue cleaning.
Start at the top of the area to be rinsed, working down with same overlapping strokes as you used for washing and applying detergent.
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 spray 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.
Adjustable Hose Reel Spring Tension
The hose reel is provided with a spring tension adjustment knob, as shown above.
Although the operator can loosen or tighten the knob to achieve the desired reel tension, the manufacturer recommends that the knob be fully hand tightened (clockwise).

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.
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 arrester 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 arrester.
Remove the three 6 mm bolts from the muffler protector, and remove the muffler protector.
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.
STORAGE
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 engine, 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 spray gun and high pressure outlet on pump. Drain water from hose and use a rag to wipe off the 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 you unit.
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 (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:
DANGER: 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.
