SAFETY RULES

THIS IS THE SAFETY ALERT SYMBOL. IT IS USED TO ALERT YOU TO POTENTIAL PERSONAL INJURY HAZARDS. OBEY ALL SAFETY MESSAGES THAT FOLLOW THIS SYMBOL TO AVOID POSSIBLE INJURY OR DEATH.

• Some chemicals or detergents may be harmful if inhaled or ingested, causing severe nausea, fainting or poisoning. The harmful elements may cause property damage or severe injury.

• Do Not allow CHILDREN to operate the pressure washer at any time.

• Operate engine only at governed speed. Running the engine at excessive speeds increases the hazard of personal injury. Do Not tamper with parts which may increase or decrease the governed speed.

• Do Not wear loose clothing, jewelry or anything that may be caught in the starter or other rotating parts.

• Before starting the pressure washer in cold weather, check all parts of the equipment and be sure ice has not formed there. See “Storage” on page 14 for cold weather protection.

• Never use a spray gun which does not have a trigger lock or trigger guard in place and in working order.

• Keep the hose connected to machine or the spray gun while the system is pressurized. Disconnecting the hose while the unit is pressurized is dangerous.

• Never operate units with broken or missing parts, or without protective housing or covers.

• Check the fuel system for leaks or signs of deterioration, such as chafed or spongy hose, loose or missing clamps, or damaged tank or cap. Correct all defects before operating the pressure washer.

• Do Not spray flammable liquids.

• Use a respirator or mask whenever there is a chance that vapors may be inhaled. Read all instructions with mask so you are certain the mask will provide the necessary protection against inhaling harmful vapors.

• Never aim the spray gun at people, animals or plants. The high pressure stream of water that this equipment produces can pierce skin and its underlying tissues, leading to serious injury and possible amputation.

• Never allow any part of the body to come in contact with the fluid stream. Do Not come in contact with a fluid stream created by a leak in the high pressure hose.

• Always wear eye protection when you use this equipment or when you are in the vicinity where the equipment is in use.

• High pressure spray can cause paint chips or other particles to become airborne.

• Do Not operate the pressure washer above the rated pressure.

• Never move the machine by pulling on the high pressure hose. Use the handle provided on the unit.

• Always be certain the spray gun, nozzles and accessories are correctly attached.

• Do Not secure the spray gun in the (open) position.

• High pressure spray may damage fragile items including glass. Do Not point spray gun at glass when in the jet spray mode.

• Hold the spray gun firmly in your hand before you start the unit. Failure to do so could result in an injury from a whipping spray gun. Do Not leave the spray gun unattended while the machine is running.

• The cleaning area should have adequate slopes and drainage to reduce the possibility of a fall due to slippery surfaces.

• Keep water spray away from electric wiring or fatal electric shock may result.

• Do Not by–pass any safety device on this machine.

• The muffler and engine heat up during operation and remain hot immediately after shutting it down. Avoid contact with a hot muffler or engine as you could be severely burned.

• Operate and store this unit on a stable surface.

• High pressure hose can develop leaks from wear, kinking, abuse, etc. Water spraying from a leak is capable of injecting material into skin. Inspect hose each time before using it. Check all hoses for cuts, leaks, abrasions or bulging of cover, or damage or movement of couplings. If any of these conditions exist, replace hose immediately. Never repair high pressure hose. Replace it with another hose that exceeds maximum pressure rating of your unit.

• The muffler and air cleaner must be installed and in good condition before operating the pressure washer. These components act as spark arresters if the engine backfires.

In the State of California a spark arrester is required by law (Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on federal lands.

NOTE: If you equip the muffler with a spark arrester, it must be maintained in effective working order. You can order a spark arrester through your authorized Sears service center.

ASSEMBLING YOUR PRESSURE WASHER

Your Craftsman high pressure washer was mostly assembled at the factory. However, you will need to perform these tasks before you can operate your pressure washer:

• Add oil to engine crankcase.

• Add fuel to fuel tank.

• Connect pressure hose to spray gun and pump.

• Connect water supply to the pump.

Add Engine Oil

IMPORTANT: Any attempt to crank or start the engine

before it has been properly serviced with the recommended oil may result in an engine failure.

NOTE: When adding oil to the engine crankcase, use only high quality detergent oil rated with API service classification SF, SG, SH, SJ or higher rated SAE 30 weight. Do Not use special additives.

• Choose a viscosity according to the table below.

* The use of multi-viscosity oils (5W-30, 10W-30, etc.)

in temperatures above 40°F (4°C) will result in higher than normal oil consumption. When using a multiviscosity oil, check oil more frequently.

** If using SAE 30 oil in temperatures below 40°F

(4°C), it will result in hard starting and possible engine bore damage due to inadequate lubrication.

• Place pressure washer on a level surface.

• Clean area around oil fill.

• Remove oil fill cap and dipstick.

• Wipe dipstick clean, insert it into oil fill hole and tighten securely, remove dipstick. Add recommended oil up to “Full” mark on dipstick.

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” 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.

• Move the throttle lever to “Fast” position, shown as a rabbit.

• Move the choke knob to the “Choke” position.

NOTE: For a warm engine, be sure the choke knob is in the “Run” position.

• Place your left foot on the lower frame and grasp the handle as shown. Your unit may appear different than that shown.

• Pull the starter grip handle lightly with your right hand until you feel some resistance, then pull briskly.

• Return the starter grip handle slowly. Do Not let rope “snap back” against starter.

• When engine starts, slowly move choke knob to the “Run” position. If engine falters, move choke knob to the “Choke” position, then to the “Run” position.

• If engine fails to start after six pulls, move choke knob to the “Run” position. If engine fires, but does not continue to run, move choke knob to the “Choke” position, then to the “Run” position.

NOTE: If the recoil starter is hard to pull, it may be necessary to squeeze the gun trigger to relieve internal pump pressure.

Throttle Lever in “Fast” Position

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 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.

CAUTION! 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 at the rear of the pressure washer.

• 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.

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

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.

MAINTENANCE

OWNER’S RESPONSIBILITIES

Follow the hourly or calendar intervals, whichever occurs first. More frequent service is required when operating in adverse conditions noted below.

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 125°–155°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.

¹ Clean if clogged. Replace if perforated or torn. ² Change oil after the first (5) operating hours and every 50 hours or every year, whichever occurs first, thereafter.

Change sooner when operating under dirty or dusty conditions.

³ Replace more often under dirty or dusty conditions.

GENERAL RECOMMENDATIONS

The pressure washer’s warranty does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, the operator must maintain pressure washer as instructed in this manual including proper storage as detailed in “Storage” on page 14.

Some adjustments will need to be made periodically to properly maintain your pressure washer.

All service and adjustments should be made at least once each season. Follow the requirements in the “Maintenance Schedule” chart on page 9.

NOTE: Once a year you should clean or replace the spark plug and replace the air filter. A new spark plug and clean air filter assure proper fuel-air mixture and help your engine run better and last longer.

BEFORE EACH USE

• Check engine oil level.

• Check water inlet screen for damage.

• Check high pressure hose for leaks.

• Check chemical filters for damage.

• Check spray gun and nozzle extension assembly

for leaks.

• 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.

CAUTION! Never repair a high pressure hose.

Replace with hose that exceeds the maximum pressure rating of your pressure washer.

Check Gun and Nozzle Extension

Examine hose connection to spray 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 spray gun immediately if it fails any of these tests.

Check In-Line Filter

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

1. Detach spray gun from high pressure hose. Detach nozzle extension from spray gun and remove o-ring and screen from nozzle extension. Flush the screen, spray gun, and nozzle extension with clean water to clear debris.

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

3. 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.

Service the spark plug every 100 hours of operation or yearly, whichever occurs first.

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 either the standard resistor spark plug, Champion RC12YC or the long life platinum spark plug, Champion RC12PYP.

• Check electrode gap with wire feeler gauge and set gap at 0.020 inches (0.50mm), if necessary.

• Install spark plug, tighten securely.

NOTE: You can purchase a new spark plug by calling 1-800-366-PART.

Carburetor

If you think your carburetor needs adjusting, see your nearest Sears service center. Engine performance may be affected at attitudes above 7000 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. If you need to order a spark arrester, please call 1-800-366-PART.

The spark arrester must be serviced every 50 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 spark arrester screen for cleaning and inspection.

• Replace if screen is damaged.

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.

• If storing for more than 30 days see “Long Term Storage” on next page.

• 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 Sears part.

• Disconnect hose from spray gun and high pressure outlet on pump. Drain water from hose, gun, and nozzle extension. Use a rag to wipe off the hose.

• Coil hose and properly hang it on the wire support provided.

• Reconnect spark plug wire to spark plug.

• Store unit in a clean, dry area.

WARNING! 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. Freeze damage is not covered under warranty.

To protect the unit from freezing temperatures:

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

• Use pump saver, available at Sears retail item # 74403, to treat pump. This minimizes freeze damage and lubricates pistons and seals.

• If pump saver is not available, 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.
