Generally, the wider the spray angle of the nozzle, the lower the spray impact produced. Select the appropriate nozzle for the job based on the following table: FIG05948 3. Release the collar, making sure it springs back and re-seats to its original (non-retracted) position. Check the connection by pulling on the nozzle to ensure a tight connection -- if correctly inserted, nozzle will rotate but not pull out. 19 Prime the Water Supply Turn on water supply and squeeze the trigger CAUTION: Water Pressure Never run the pump without the water supply connected and turned on. Operating the pressure washer without a sufficient incoming flow of water will damage the pump. · Turn on the water supply. Make sure the water supply is steady and flowing at a rate 20% over the rated flow of your pump. (Reference the flow rate table under the "Connect Hoses, Water Supply, and Nozzle" section). · Purge air from the water supply hose by squeezing the trigger until a steady stream of water flows out of the nozzle at low pressure. (Air in the hoses can cause damage to the pump, so always make sure all the air is out of the hoses before starting the pressure washer engine.) · Make sure the water supply hose is not kinked. A kinked hose will provide insufficient water supply to the pump and reduce its life. Make sure the hose remains unkinked after moving the pressure washer. Set Up for Chemical Spray (if desired) Using the proper cleaning chemical for the application can speed up cleaning jobs tremendously. Your pressure washer is equipped with a chemical injection point on the downstream side of the pump for introducing cleaning chemicals into the water stream. A braided chemical hose is provided to connect at this point. Suction pressure at this connection automatically draws the chemical solution in through the hose, mixing in 1 part chemical to 15 parts water. Adequate suction pressure is created only when the low pressure (black) spray nozzle is used. The introduction of cleaning chemicals via the chemical injection point affords the following advantages: CAUTION: Chemicals Containing Muriatic Acid Certain chemicals, such as bleach or those containing muriatic acid, will cause pump damage if introduced upstream through the pump's water inlet. It mixes the cleaning chemical into a low pressure spray. Cleaning chemicals applied under low pressure adhere better to the surface being cleaned, allowing the formula time to react and remove dirt more effectively. Note: An external chemical injector pump is not recommended for use with this pressure washer, and if used would obviously alter the 15-to-1 dilution ratio. WARNING: Chemical Spraying · Never spray acids, corrosives, or abrasive or flammable liquids. Breathing hazards, surface burns/corrosion, or fire/explosion could result. · Follow the chemical manufacturer's label instructions for proper use and handling of the chemical. Understand all safety hazards and first aid for all chemicals being used. Always wear protective gloves when handling and cleaning with chemicals, and wear other protective gear as directed by chemical manufacturer. Always dispose of hazardous fluids per local, state, and national guidelines. Acquire Cleaning Chemical Use only approved pressure washer chemicals designed for high-pressure use. CAUTION: Non-approved Chemicals Non-approved chemicals can damage pressure washer components (seals, wand, hoses, pump, etc.) and be harmful to the environment. Prepare for Chemical Spray (If Planning to Use) Prepare the pressure washer for chemical spraying using the following steps: 1. Prepare (dilute) chemical cleaning solution as required for the job. (Note: the chemical solution will be automatically mixed with the water at a ratio of 15 parts water to 1 part chemical solution.) 2. Ensure that the braided chemical hose is pressed onto the chemical injector on the pump. · It protects the pump from damage because no chemical passes through the pump. 20 Start-Up Procedures Start the Engine to Power the Pump. 1. Make sure water supply is connected and primed. CAUTION: Warranty Void Running the pump dry will cause damage and void the warranty. Pump Components 2. To prevent accidental spraying, engage the safety latch on spray gun trigger by rotating it to the FIG05949 locked position. 3. Follow the instructions in the "Engine Manual" section of this manual for starting the engine. - If the engine doesn't start on the first try, pressure may build up in the pump. Relieve pressure by squeezing the spray gun trigger before attempting to start engine again. This will make starting easier. DANGER: Engine Exhaust Do not inhale engine exhaust. It contains dangerous carbon monoxide that can kill you. Apply Cleaning Chemical (If Desired) 1. Make sure the chemical injector is properly set up according to the instructions. Reference "Set Up for Chemical Spray" on the previous page. 2. Make sure the low pressure BLACK nozzle is attached before beginning to spray chemicals -Only the low pressure black nozzle will allow chemicals to be drawn through the chemical injector into the water stream. 3. Apply chemicals by squeezing the spray gun trigger. The chemical injector will draw the chemical into the water stream. 4. Apply chemicals evenly to the cleaning surface. Never use more chemical than is necessary to clean the surface. 5. Allow the chemicals time to react with the dirt before rinsing. 6. Prepare to rinse by changing to a high-pressure nozzle. Changing the nozzle from the low-pressure black nozzle to a high-pressure nozzle will stop the flow of chemicals into the water stream. Instructions for selecting a nozzle can be referenced in the "Connect Hoses, Water Supply, and Spray Nozzle" section. Also see the subsection "Select Nozzle for Spray Gun". Begin High Pressure Spray WARNING: High Pressure Spraying Safety · Keep spray away from people. Never direct discharge stream at or near any person. Do not allow any part of the body to come in contact with the fluid stream. High-pressure spray can cause serious skin, eye, or falling injuries. Injection injury will occur if high-pressure spray pierces the skin, injecting liquid under the skin. Injection injury can result in blood poisoning and/or severe tissue damage leading to infection, gangrene and possibly amputation. Seek medical attention. · Do not secure trigger open. To reduce risk of injury, do not attempt to secure the spray gun open by blocking or tying the spray gun in the open position. · Prevent slips / loss of balance. High-pressure spray could cause you to lose balance from kickback forces, and wet surfaces can be slippery. - Keep good footing and balance at all times. Do not overreach. - Do not stand on unstable support when spraying. - If spraying from an elevated surface, use fall protection because spray gun kickback can propel you off the elevated surface. When spraying from a ladder or scaffolding, ensure it is firmly anchored from sway or tip-over. - Be aware of puddles and slippery surfaces. Ensure there is adequate drainage to prevent pooling of water. · Prevent surface damage & flying debris Surfaces being sprayed must be strong enough to withstand high-pressure spray or damage may result. In addition, high-pressure spray will dislodge unsecured objects as well as surface chips and debris, resulting in hazardous flying objects that can cause personal injury or property damage. Do not spray brittle surfaces or breakable, fragile, or unsecured objects such as: o stucco or laminar flagstone o some painted surfaces o windows or glass doors (because they may break) o light fixtures, flowerbeds, mailboxes o unsecured, lightweight objects 7. Rinse with high-pressure spray as instructed below. 21 Procedure: 1. Install one of the high-pressure spray nozzle (always relieve system pressure first and follow instructions for attaching a nozzle). 2. Clear the cleaning area of all persons. Keep children and pets away. 3. Hold the spray gun firmly with two hands and a sturdy stance -- Gun kicks back when triggered. 4. Wash from the bottom to the top, using side-toside motions. This washes away heavy dirt and allows the detergent to soak as you work toward the top. 5. Use the width of the spray pattern to wash a wide path. Overlap spray paths for complete coverage. 6. The nozzle should be 12" to 24" from the work, closer for tough areas. 7. Small parts should be washed in a basket so the pressure does not push them away. Larger, lightweight parts should be clamped down. 8. The pressure washer is set and locked to the maximum rated pressure when it leaves the factory. To reduce the pressure, turn the unloader knob counterclockwise. To return to maximum pressure turn unloader knob clockwise. Pressure Adjustment (Unloader) FIG05956 Spray Gun Safety Lock When not spraying, use the spray gun safety lock to prevent accidental high pressure discharge. Spray Gun FIG05950 Safety Lock 10. Always turn off the engine and activate spray gun trigger to relieve system pressure when: · the sprayer is unattended · disconnecting hoses, installing/cleaning nozzles, or servicing the pump. WARNING: High Pressure Fluid Hazard Always turn off the engine and relieve system pressure when finished spraying or when leaving sprayer unattended. Serious injury could result from unintentional release of highpressure spray. Shutdown Stop the engine using the following steps: WARNING: High Pressure Fluid Hazard Never disconnect the high-pressure hose from the pump or spray gun while the system is pressurized. Relieve pressure by squeezing the spray gun trigger after the engine is turned OFF. WARNING: High Pressure Fluid Hazard Do not attempt to alter the unloader valve's maximum pressure. Excess pressure could cause serious injury from escaping highpressure fluids and/or pump damage. Any alteration other than turning the adjustment knob will void your warranty. 9. If temporarily interrupting spraying, rotate trigger safety latch downward to the locked position to guard against accidental trigger release. 1. Turn engine OFF. 2. Turn water supply OFF. 3. Actuate spray gun trigger to relieve system pressure. 4. Remove garden hose. 5. Remove pressure hose. 6. Remove nozzle from spray gun. 7. Turn gasoline line valve to the OFF position. 8.

(2) These items should be serviced by an authorized generator service center, unless the owner has the proper tools and is mechanically proficient. CAUTION: Engine damage The pressure washer has been shipped WITHOUT oil. Any attempt to start pressure washer without oil may result in engine damage and failure. · Engine oil is a key factor in deciding the engine's performance. DO NOT use engine oil with additives or 2-stroke gasoline oil, as they do not lubricate properly, which may shorten the engine's service life. · Check the engine oil level with the generator stopped on a level ground. · Due to viscosity variances with regions and temperatures select the correct type of oil using the chart below. Engine oil recommended: SAE10W-30 Capacity: 0.63 US quarts (0.6L) 38 Oil draining and checking oil level WARNING: Burn hazard Never open oil port while engine is running. Hot oil can spray over face and body. 1. Operate the pressure washer for 3 to 5 minutes to thin oil for easier draining. 2. Ensure that the engine is stopped and on a level surface. 3. Remove the drain bolt and washer; drain the oil into an approved container. Spark plug removal, cleaning and replacement 4. Reinstall washer and drain bolt. 5. Remove the dipstick and clean it. 6. Fill crankcase with oil to the bottom lip of the oil filler neck, approximately 0.63 US quarts (0.6L). 7. Reinsert the dipstick into the oil filler without threading in, and check oil level. If the oil level is too low, add recommended engine oil to the oil filler neck. 8. Reinstall the dipstick. Proper spark plug clearance ensures the engine's normal running. a) Remove the spark plug cap. b) Remove the spark plug using a spark plug wrench. WARNING Be careful not to touch the muffler during or just after the engine has been running. c) Clean the spark plug with a steel brush. If the insulator is damaged, replace the spark plug. d) Measure the spark plug clearance with a feeler. The clearance should be 0.7-0.8mm. If adjustment is necessary, bend the side electrode carefully. e) Check if the spark plug gasket is in good conditions, or replace with a new one. Screw on the spark plug to the bottom first by hand and then tighten it up by a using spark plug wrench. If a new spark plug is used, twist 1/2 more turns after impacting the gasket; if reinstall the original one, just twist 1/8-1/4 more turns. 39 Clean air filter WARNING Never run the pressure washer without the air filter. Rapid engine wear will result. 1. Remove the air cleaner outside cover (A). Be careful to prevent dirt and debris from falling into the air cleaner assembly. 2. Separate the Air Filter (A) from the Air Filter Housing (B). 3. Inspect the air filter. Clean dirty air filter with warm water and mild soap. Allow air filter to dry thoroughly before re-installation. 4. Install the air filter assembly onto the carburetor and secure with screws. A Note: Do not use pressurized air or solvents to clean the filter. Pressurized air can damage the filter and solvents will dissolve the filter. B Prepare engine for long term storage if needed If you will not be able to exercise the pressure washer regularly, you must prepare the engine for long term storage to prevent gum deposits from forming and causing malfunction of the engine. Prepare engine for long term storage by: Removing all gasoline from the tank and carburetor. Draining steps: 1. Position a UL-listed fuel container below the carburetor drain bolt. 2. Turn fuel valve to the OFF position. 3. Remove the drain bolt and gasket. 4. Turn fuel valve to the ON position and drain fuel from carburetor and tank. 5. Reinstall and tighten the drain bolt and gasket. OR Adding fuel stabilizer to the gasoline (following manufacturer's instructions). Fuel stabilizer steps: 1. Ensure gasoline tank is full. 2. Add fuel stabilizer to fuel tank. 3. Run engine at least 10 minutes after adding stabilizer to allow it to enter the fuel system. 4. Shut off engine. 5. Disconnect spark plug wire and remove spark plug using a spark plug wrench. 6. Add one teaspoon oil through spark plug hole. 7. Place rag over spark plug hole and turn starter (or pull the recoil) a few times to lubricate the combustion chamber. 8. Replace spark plug, but do NOT reconnect the spark plug wire. 40 Removal WARNING from storage Gasoline is highly flammable and explosive, and you can be burned or seriously injured when handling fuel.
