Initial Set-Up Elevating or lowering your pressure washer • To reduce risk of injury, it is recommended that two adults lift the pressure washer. • Only lift the pressure washer by the bumper and handle. Do not use the pump or engine as a lifting point. inside RVs or other vehicles, on boats, or on pick-up truck beds. Positioning: 1. The pressure washer should be positioned on a firm, level (less than 3 degree slope), heatresistant surface with good drainage and a nearby water supply. 2.
Initial Set-Up 3. Keep a fire extinguisher rated "ABC" nearby. Keep it properly charged and be familiar with its use. 4. Place the unit so that the exhaust fumes will not be directed towards people or building air intakes. DANGER: Carbon monoxide hazard Exhaust fumes from the engine contain carbon monoxide (CO), a poisonous gas you cannot see, smell, or taste.
Operation Follow Safety Rules for Operation set-up and operation. Do not allow anyone to operate the pressure washer who has not read the Owner's Manual and been instructed on its safe use. Adult control only. Only trained adults should set up and operate the pressure washer. Do not let children operate. Pressure washers can generate forces greater than children can control and require judgment beyond what can be expected of children. Under the influence.
Operation Preparing for Operation Never pull by hose. Do not move this machine by pulling on the hose. Hose or connections could fail and result in catastrophic high pressure release of fluid as well as hose whipping. Avoid sharp objects. Keep hose away from sharp objects. Bursting hoses may cause injury. No load bearing. Do not use the pump to support other items of equipment that impose unacceptable loads on the pump. Do not attempt to use this machine as a prop.
Operation Always follow these general safety rules when fueling: 1) Turn pressure washer off and allow to cool for at least two minutes before removing any fuel cap. Note: A running or still-hot engine is hot enough to ignite fuel. - Do NOT overfill the gasoline tank. Allow at least 1/2" of empty space below the fill neck to allow for fuel expansion. 3) Replace gas cap securely before starting engine. 4) Store extra gasoline in a cool, dry place in a UL approved tightly sealed container.
Operation WARNING: High Pressure Fluid Injection Hazard 3.) The water supply garden hose must have an inside diameter of at least 5/8”. If the hose is more than 100 ft. long, the diameter must be at least 3/4”. 4.) The water source pressure must not exceed the pressure listed below. High-pressure fluid discharge from leaks (even pinsized) or ruptured components can pierce skin and inject fluid into the body.
Operation Nozzle for Spray Gun 3. Connect one end of the ¾” hose to the water tank. 4. Connect the other end of the ¾” hose to the pump. Make sure the connection hose will not kink. 5. Fill the tank to desired level. Your pressure washer is equipped with four highpressure nozzles and one low-pressure nozzle. Generally, the wider the spray angle of the nozzle, the lower the spray impact produced.
Operation 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. CAUTION: Chemicals Containing Muriatic Acid • 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.
Operation Apply Cleaning Chemical (If Desired) Pump 1. Make sure the chemical injector is properly set up according to the instructions in Step 2, "Set Up for Chemical Spraying". 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.
Operation 3. Hold the spray gun firmly with two hands and a sturdy stance -- Gun kicks back when triggered. 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.
Operation Shutdown Stop the engine using the following steps: WARNING: Injury 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. Unloader 9. If temporarily interrupting spraying, rotate trigger safety latch downward to the locked position to guard against accidental trigger release.
Storage When you are finished using the pressure washer, you must prepare the sprayer for storage and store it in a proper location. 1. Drain the water from the high pressure hose and spray gun by depressing the trigger on the spray gun until all water drains out. 2. Disconnect the plumbing that connects to the pump outlet. 3. Obtain the materials you will need: • 12" piece of garden hose or equivalent • funnel • approximately 6 oz. of RV antifreeze. 4.
Storage • Add fuel stabilizer to the gasoline (following manufacturer's instructions) Fuel stabilizer steps: a. Ensure gas tank is full. b. Add fuel stabilizer to fuel tank. c. Run pressure washer with high pressure hose at least 5 minutes after adding stabilizer to allow it to enter the fuel system. d. Shut off engine 2. Lubricate cylinder and piston: a. Disconnect spark plug wire and remove spark plug b. Add one teaspoon oil through spark plug hole c.
Maintenance & Repair WARNING: Maintenance Hazards ALWAYS shut off water supply, bleed water pressure, turn off engine and disconnect the spark plug wire before cleaning, adjusting, or servicing the pressure washer. After servicing, make sure all guards and cover shields are replaced before using.
Maintenance & Repair WARNING: High Pressure Fluid Injection Hazard Clean Inlet Filter Clean the inlet filter before each use. High pressure fluid discharge from leaks (even pin-sized) or ruptured components can pierce skin and inject fluid into the body. Injection injury can result in blood poisoning and/or severe tissue damage leading to infection, gangrene, and possibly amputation.
Maintenance & Repair NOTICE: Perform Engine Maintenance Dispose of used motor and pump oil in a manner that is compatible with the environment and in accordance with local, state, and federal laws and regulations. -As specified in the engine owner's manual. Engine maintenance items include: 1. Changing oil and oil filter 2. Air filter check/replacement 3. Spark plug cleaning and replacement 4. Fuel filter check/replacement 5.
Maintenance & Repair Note: Some general rules of belt tension are: • The ideal tension is the lowest tension without belt slippage • Over tightening decreases belt and bearing life. • Keep belts clean and free of foreign material that may cause slippage • Do not apply belt dressing, which can cause damage and early belt failure. 6) Ensure all belts are the same tension. 7) Re-tighten pump mounting bolts. Torque to 29.4 ftlbs. 8) Replace belt guard.
