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. A Twistingthe nozzle adjusts the spray pattem from a narrow pattern to a fan pattern. WARNING NEVER adjust spray pattern when spraying. NEVER put hands in front of spray nozzle to adjust spray pattern. You could be injured. HOW TO ADJUST PRESSURE AND SPRAY PATrERN On the end of yourspray gun is a nozzle that you can slide forward and backward and that you can also twist from side to side. With the adjustable nozzle you can adjust the spray pattern to be either high pressure or low pressure. You can also adjust the spray so it is concentrated in a stream pattern or expanded into a fan pattern. • TWIST NOZZLE FOR FAN SPRAY PATTERN Located on the front of the pump is the pressure control knob. You can increase the pressure of the spray by turning the knob clockwise or decrease the pressure by turning the knob counterclockwise, i TWIST NOZZLE FOR NARROW SPRAY PATTERN between 8 to 24 inches away from cleaning surface. For most effective cleaning, keep spray nozzle If you get spray nozzle too close, especially using high pressure mode, you may damage the cleaning surface. APPLYING DETERGENT AND CLEANING WITH ADJUSTABLE NOZZLE IMPORTANT: Use soaps designed specificallyfor pressure washers. Household detergents could damage the pump. Slide the nozzle forward when you wish to adjust the spray to low pressure mode. Slide the nozzle backward to achieve high pressure (see "Adjusting the Spray Pattern in figure below). 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. Note: The first step involves applying an appropriate detergent/solvent solution to penetrate and loosen grime. The detergent is applied at low pressure to avoid splashing, overspraying and waste. Leave the solutionon surface for 3 to 5 minutes to allow solution to work. Note: The second step involves cleaning the surface you have prepared with the pressure washe r and then rinsing it clean. NOZZLE IN HIGH PRESSURE MODE SLIDE NOZZLE FORWARD FOR LOW PRESSURE MODE AND DETERGENT APPLICATION Toapplydetergent followthesesteps: • Prepare the detergent solution as required by the job. • Hang the detergent solution on the "J" hook on the wire form on the guide handle. RINSING WITH THE PRESSURE WASHER A WARNING Be extremely careful if you must use the pressure washer from ladder, scaffolding or any other relatively unstable location. Pressure in a running washer builds in the wand as you climb. When you press the trigger, the recoil from the initial spray could force you to fall, or if you are too close to the cleaning surface, high pressure could force you off a climbing apparatus. • Hook up the water supply and start your pressure washer (see "TO START THE PRESSURE WASHER" on page 10). • Slide adjustable nozzle rearward to high pressure position and wait for detergent to clear. Detergent will not flow when in the high pressure mode. When detergent has cleared you may want to expand the spray pattem for a more gentle rinsing action. Start at top of area to be rinsed, working down with same action as for cleaning, • Place small filter of the clear, chemical injection tube into the detergent container. • Slide the adjustable nozzle forward to low pressure mode. Detergent cannot be applied with nozzle in high pressure position. • You can also stop detergent from flowing by simply removingsiphonfrom bottle. HOW TO STOP YOUR PRESSURE • Review the use of the adjustable nozzle on Page 7. WASHER First, move the engine Throttle Control Lever to STOP position, Connect garden hose to water inlet (see "TO START PRESSURE WASHER" on page 10), check that high pressure hose is connected to spray gun and pump (see "ASSEMBLY" on page 5), and start engine.. • Apply detergent to a dry surface, starting from the bottom and working up. • Allow the detergent to soak in between 3-5 minutes before washing and rinsing. Note: To adjust the concentration of the mixture of cleaning chemical and water, turn the smaller black knob next to the pressure regulator. CHOKE Position • Simply shuttting OFF the engine will not release pressure in the system. 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. BEFORE STARTINGTHE PRESSUREWASHER ADD GASOUNE To operatethe engine you will need to do the following: A ENGINE OIL A 20 oz. bottle of SAE 30 weight oil is included in the parts carton. Fill engine crankcase with recommended oil until oil level is at FULL point on dipstick. Do not fill above that mark. About 20 ounces is required. POUR SLOWLY. Note: When adding oil to the engine crankcase in the future, use only high quality detergent oil rated with API service classification SF and SG rated SAE 30 weight. Use no special additives. Select the oil's viscosity grade according to your expected operating temperature. I I colder 5W30 _ 32°F _ warmer SAE 30 Although multi-viscosity oils (5W30, 10W30, etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible damage from running low on oil. Oil sump capacity is 20 ounces. • Place pressure washer on a level surface • Clean area around oil fill and remove oil dipstick. • Wipe dipstick clean. Pour oil from the enclosed bottle into the oil fill opening until oil reaches FULL mark on the dipstick.DO NOT OVERFILL. • Install oil dipstick, hand tighten securely. A • WARNING NEVER fill fuel tank Indoors. NEVER fill fuel tank when engine is running or hot. DO NOT light a cigarette or smoke when filling the fuel tank. CAUTION: Do not overfill the fuel tank. Always leave room for expansion. Use regular UNLEADED gasoline with the pressure washer engine. Regular leaded gasoline may also be used if UNLEADED is not available. Fuel tank capacity is 1 U.S. quart. IMPORTANT: It is importantto prevent gum deposits from forming in essential fuel system parts such as the carburetor,fuel filter, fuel hose or tank during storage. Also, experience indicatesthat 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. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. See "Storage" on page 15. Never use engine or carburetorcleaner productsin the fuel tank or permanent damage may occur. • Clean area around fuel fill cap, remove cap. • Add "UNLEADED" regular gasoline, slowly, to fuel tank. • Install fuel cap and wipe up any spilled gasoline. TO START YOUR PRESSURE • WASHER You have assembled your high pressure washer and have prepared the engine for starting. You are now ready to clean your car, boat or the outside of a buildingor whatever you plan to clean: Reconnect the wand extension Note: After reconnectingthe wand extension, you may need to squeeze trigger again on pressure washer wand to relieve the air pressure caused by water inlet supply. Water will spew out of the gun in a thin stream. This will make it easier to pull start the engine. The best way to start your engine-powered pressure washer for the first time is to follow these instructions step-by-step. This starting informationalso applies whenever you start the engine after you have let the pressure washer sit idle for at least a day. • Engage safety latch on spray gun to the ON position. This disables the trigger so you cannot inadvertently actuate a high pressure spray. Place the pressure washer in an area close enough to an outside water source that can flow at a rate of 3 gallons per minute. Connect a garden hose to the water spout. ON __ • Check that the high pressure hose is tightly connected to the spray gun and to the pump. See ASSEMBLY section for illustrations. • Connect the garden hose to water inlet opening on the pressure washer pump and turn ON the water. WATER INLET • Turn the pressure control knob counterclockwisetwo turnsfrom maximum pressure (see Page 7). • Grasp the starter grip and pull slowly until you feel resistance. Then pull rapidly up to two (2) times. • When engine starts, move the Throttle Control Lever to the FAST position. If engine fails to start, press the trigger to relieve the pressure, set the Throttle Control Lever to FAST position,then pull starter handle slowly until you again feel resistance and then pull up to two (2) times rapidly. • Allow engine to run for two minutes before using. Check inlet screen If screen is damaged DO not connect water. • Set THROTTLE CONTROL LEVER to CHOKE position (see Page 8). • Remove the wand extension and squeeze the trigger to purge pump system of air and impurities. OFF • Once engine has started, place Safety Latch in the OFF position. IMPORTANT: An internalthermal relief valve has a maximum temperature setting of 140°F (60°C). If you run the pump for 5 minuteswithout pressingthe trigger on the spray gun, 1/2 to I ounce of water is released through the valve to cool the unit. The small amount of water will drip out the bottom of pump. SIPHONING we recommend that you DO NOT siphon-yourwater supply. Connect only to householdwater supply. TIPS • Never use the garden hose inlet to siphon detergent or wax. • I0 If you have the spray nozzle too far away, the cleaning will not be as effective.

Turn wand to stream spray and move nozzle from low to high pressure while flushing. 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 sensation during use. This generally is not a pump related problem, but rather a clogged or partiallyrestricted nozzle. ! If the nozzle becomes clogged or partially restricted, immediately clean the nozzle with the kit includedwith your pressure washer by followingthese instructions: Shut off the engine and turn off the water supply. Separate the wand from the gun. Rotate to stream setting. Remove nozzle from the end of the wand using a 2mm or 5/64 allen wrench (like the one includedin the kit). Insertwire intonozzle and turn back and forth to clear obstruction. • Reinstall nozzle into wand. DO NOT overtighten. • Reconnect wand extension to spray gun. • Reconnect the water supply, turn ON the water, and start the engine. • Test the pressure washer by operating with nozzle in the high and the low pressure positions. AFTER EACH USE Water should not remain in the unit for long periods of time. Sediments of mineralscan deposit on pump parts and "freeze" pump action. Follow these procedures after every Use: • • Flush detergent hose by placing the injector filter into a pail of clear water while running Pressure Washer with nozzle in low pressure mode. Flush until you can see clear water running through the tube. Shut off the engine and let it cool, then remove all hoses. A CAUTION: Be sure throttle lever is in "STOP" position before you continue. If you start engine without the proper water supply connected, you can damage the pump. 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. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Follow these instructions: PROTECT FUEL SYSTEM • _1_ Empty the pump of all pumped 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 of it 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 on the guide handle. Note: To protect the unit from freezing temperatures, you can draw windshieldwasher fluid into the pump by pouring the washer fluid into a 3-foot section of garden hose connected to the inlet adaptor and pullingthe recoil handle twice. • Remove all gasoline from the fuel tank to prevent gum deposits from forming on these parts and causing possible malfunction of engine. • WARNING: Drain fuel into approved container outdoors, away from open flame. Be sure engine is cool. Do not smoke. Run engine until engine stops from lack of fuel. Make sure you have water supply to pump inlet connected and turned ON. CHANGE OIL While engine is still warm, drain oil from crankcase. Refill with recommended grade. OIL CYLINDER BORE • Remove spark plug and pour about 1/2 ounce (15ml) of engine oil into the cylinder. Cover spark plug hole with rag. Crank slowly to distribute oil. I A • Install spark plug. Do not connect spark plug wire. CAUTION!
