important safety warnings fire & ventilation precautions: 1. This unit was designed for outdoor use only. NEVER operate this unit in an enclosed area. ALWAYS make certain there is adequate air (oxygen) for combustion as well as ventilation to prevent the presence of poisonous carbon monoxide gases. Beware of poorly ventilated areas or exhaust fans which can cause inadequate combustion or engine overheating. 2. DANGER: Carbon monoxide produced during use CAN KILL in minutes. NEVER use indoors, in a vehicle or in other sheltered areas, EVEN IF doors and windows are open. Only use OUTSIDE and far away from windows, doors and vents. a. Carbon monoxide is an odorless, colorless, poison gas. Breathing carbon monoxide can cause headache, fatigue, dizziness, vomiting, confusion, seizures, nausea, fainting or death. If you start experiencing any of these symptoms, IMMEDIATELY move to fresh air. Seek medical attention. b. Keep exhaust gas from entering confined area through windows, doors ventilation intakes, or other openings. Warn any occupants inside about the symptoms of carbon monoxide so they know to move to fresh air if they begin to feel ill. c. The use of a carbon monoxide detector inside any occupied premise between the power washer and the occupant is recommended. d. Use a respirator or mask whenever there is a chance that harmful gas or vapors may be inhaled. e. Read all instructions with respirator or mask so you are certain the respirator or mask will provide the necessary protection against inhaling harmful gas or vapors.

important safety warnings miscellaneous safety precautions: 1. NEVER ALLOW ChILDREN OR ADOLESCENTS TO OPERATE ThIS UNIT! 2. Read and follow all handling, operations, maintenance and safety instructions listed in this manual and the Engine Operator’s manual that accompanies this unit, and provide such information to ANYONE who will be operating this unit. 3. In freezing temperatures, the unit must always be warm enough to ensure there is no ice formation in the pump. DO NOT start this unit if it has been transported in an open or underheated vehicle without first allowing the pump to thaw. 4. When connecting the water inlet to the water supply mains, local regulations of your water company must be observed. In some areas the unit must not be connected directly to the public drinking water supply. This is to ensure that there is no feedback of the detergents into the water supply. (Direct connection is permitted if a back flow preventer is installed.) 5. DO NOT allow any part of your body or the high pressure hose to make contact with the muffler. Avoid dragging the hose over an abrasive surface such as cement. This causes wear and eventual rupturing. -
Page 7: Adjustment Precautions
1. NEVER alter or modify the equipment, be sure any accessory items and system components being used will withstand the pressure developed. Use ONLY genuine Generac parts for repair of your power washer. Failure to do so can cause hazardous operating conditions and will void warranty. 2. NEVER make adjustments to the machinery while it is connected to the engine without first removing the ignition cable from spark plug. Turning the machinery over by hand during adjustment or cleaning might start the engine and machinery with it, causing serious injury to the operator. 3. Know how to stop the power washer and bleed pressures quickly. Be thoroughly familiar with controls. 4. Before servicing the unit; turn the unit off, relieve the water pressure, and allow the unit to cool down. Do not make repairs while unit is running. Service in a clean, dry, flat area. Block the wheels to prevent the unit from moving. 5. Follow the maintenance instructions specified in this manual. ! save tHese instructions ! -

Page 12: Water Supply
installation & preparation water supply: 1. Select a water supply hose which is a quality grade of garden hose measuring at least 3/4” ID and no longer than 50 feet. 2 Check the water inlet strainer to ensure it is clean and free of any obstructions. Periodic cleaning of the water strainer will help prevent pump problems. As a strainer becomes obstructed, it restricts proper flow of water to the pump. This can result in cavitations which will cause premature failure of pump packings. a. Using a screw driver, remove the screen from the water inlet. b. Clean or replace if necessary. 3. Connect the hoses: a. Connect one end of the water supply hose to the water inlet of the unit. b. Connect the other end of the hose to your pressurized water supply. When connecting the water inlet to the water supply mains, local regulations of your water company must be observed. In some areas, the unit must not be connected directly to the public drinking water supply. This is to ensure that there is no feedback of the detergents into the water supply. (Direct connection is permitted if a back flow preventer is installed.) c. Quick-connect the high pressure discharge hose to the water outlet of the unit. -
