Bypass Mode: In bypass mode, the pump is recirculating water because the trigger of the spray gun is not pulled. If unit is left in bypass mode for more than two minutes.The water pressure will rise to a dangerous level and could damage internal components of the pump. Any damage to pump due to these causes will not be covered under warranty.CAUTION Do not allow unit to operate in bypass mode for more than two minutes at any time. Overheating of pump can cause damage to pump.Thermal Relief Valve: In an effort to prevent extreme damage, pumps are equipped with a thermal relief valve. This valve will open the temperature inside the pump rises too high. This valve will then release a gush of water in an effort to lower the temperature inside the pump. Immediately after this occurs, the valve will close.Chemical Injection System: Mixes cleaners or cleaning solvents with the pressurized water to improve cleaning effectiveness.Water Supply: All pressure washers must have a source of water. The minimum requirement for a water supply is 20PSI and 5 gallon per minute.WASHER PUMP OPERATING FEATURES.PRESSURE REGULATORThe pressure setting is preset at the factory to achieve optimum pressure and cleaning.If you need to lower the pressure,it can be accomplished by these methods.1. Back away from the surface to be cleaned. The further away you are,the less the pressure will be on the surface to be cleaned. CAUTION Do not attempt to increase pump pressure. A higher pressure setting than the factory set pressure may damage pump. 2. Reduce the speed the gasoline engine (RPM). Slow the engine down and the water pressure will go down with it.3. Change to a nozzle , This nozzle delivers a less powerful stream of water and a wider spray pattern.4. Adjust the pressure regulator on the pump . Turn the pressure regulator knob counter-clockwise to lower pressure. Once you have finished using your pressure washer, return the pressure regulator to it's original position by turning it clockwise.CAUTION Do not try to turn pressure regulator knob past the build-in stop or pump may be damaged. How to apply chemicals and cleaning solventsCAUTION Applying chemicals or cleaning solvents is a low pressure operation. Use only soaps and chemicals designed for washer pumps, DO NOT use bleachHOW TO APPLY CHEMICALS AND CLEANING SOLVENTS:Press chemical hose onto barbed fitting located near the high pressure hose connection of the pump.Place other end of chemical hose with filter on it into container holding the chemical solution.NOTE: The chemical/water ratio is 1:7, for every 7 gallons of water pumped, 1 gallon of chemical/ cleaning solution will be used.Change to the low pressure nozzle.After use of chemicals, place chemical hose into container of clean water and draw clean water through chemical injection system to rinse system thoroughly. If chemicals remain in the pump it could be harmful to the pump. Pumps that are damaged due to chemicals will not be covered under warranty.NOTE: Chemicals and soaps will not siphon when lance is in the high pressure setting.WARNINGSCAUTION When using the high pressure setting, DO NOT allow the high pressure spray to come in contact with unprotected skin, eyes, or with any animals. Serious injury can occur.Your washer operates at fluid pressures and velocities high enough to penetrate human and animal flesh, which could result in amputation or other serious injuries. Leaks caused by loose fittings or worn or damaged hoses can result in injection injuries. DO NOT TREAT FLUID INJECTION AS A SIMPLE CUT. See a physician immediately. WARNING NEVER fill fuel tank when engine is running or hot. DO NOT smoke when filling the fuel tank.NEVER fill the fuel tank completely. Fill the tank to 1/2" below the bottom of the filter neck to provide space for fuel expansion. Wipe any fuel spillage from engine and equipment before starting the engine.NEVER run engine indoors or in enclosed, poorly ventilated areas. Engine exhaust contains carbon monoxide, and odorless and deadly gas.NEVER let hoses come in contact with very hot engine muffler during or immediately after use of your washer pump. Damage to hoses from the contact with hot engine surfaces will NOT be covered by warranty.NEVER pull water supply from hose to move washer pump. This could damage hose and pump inlet.NEVER use hot water. COLD WATER ONLY.NEVER turn water supply while washer pump engine is running or damage to pump will result.DO NOT STOP spraying water for more than two minutes at a time. Pump operates in bypass mode when spray gun trigger is not pressed. If pump is left in bypass mode for more than two minutes internal components of the pump can be damaged.STARTINGPrior to starting, refer to your engine manual for proper starting procedures for your engine type.In a well ventilated outdoor area add fresh, high quality, unleaded gasoline with a pump octane rating of 86 or higher.
