Also, the high and low pressure settings can be controlled by moving the nozzle in and out. See Operation section. High Pressure Hose Chemical Hose: Allows cleaners or cleaning solvents to be mixed with the pressurized water stream. See How To Siphon Chemicals/Cleaning Solvents in Operation section of this manual. ENGINE Choke Control: Opens and closes the choke valve in carburetor. Throttle Control Lever: Controls engine speed. Starter Grip: Pulling starter grip operates recoil starter to crank engine. Fuel Valve Lever: Opens and closes connection between fuel tank and carburetor. D25083 10- ENG PRESSURE WASHER TERMINOLOGY NOTE: Become familiar with this terminology before operating. PSI: Pounds per Square Inch. The unit of measure for water pressure. Also used for air pressure, hydraulic pressure, etc. GPM: Gallons Per Minute. The unit of measure for the flow rate of water through the pressure washer. CU: Cleaning Units. GPM multiplied by PSI. 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 (2) minutes, the water temperature will rise to a dangerous level and damage internal components of the pump.Any damage to pump due to these causes will not be covered under warranty. DO NOT allow your 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 damage, pumps are equipped with a thermal relief valve. This valve will open when 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: Feeds cleaning agents into the pump to mix with the pressurized water and help in cleaning. Water Supply: All pressure washers must have a source of water. The minimum requirements for a water supply are 20 PSI and 5 gallons per minute. HOW TO USE IMPORTANT: Read and understand how to use the pressure washer before operating. TO ADJUST PRESSURE The 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. 2. Reduce the speed of the gasoline engine (RPM). Slow the engine down and the water pressure will go down with it. DO NOT attempt to increase pump pressure. A higher pressure setting than the factory set pressure may damage pump. TO USE WAND Your pressure washer is equipped with a multi-reg wand with both high and low pressure settings. The high pressure setting is for cleaning and rinsing, the low pressure setting is for applying chemicals or cleaning solutions to surfaces. Risk of injection or injury to person. Do not direct discharge stream toward persons, unprotected skin, eyes, or towards any pets or animals. Serious injury can occur. For high pressure operation, pull back the nozzle of the multi-reg wand as shown. 11- ENG D25083 The nozzle at the end of the multi-reg wand can be rotated to change the high pressure spray pattern from a narrow jet to a 40. fan shape, as shown. Markings have been placed on the nozzle to help you select the spray pattern. 40. fan spray narrow jet stream For low pressure operation, extend the nozzle of the multi-reg wand as shown. TO SIPHON CHEMICALS/CLEANING SOLVENTS Siphoning chemicals or cleaning solvents is a low pressure operation. NOTE: Use only soaps and chemicals designed for pressure washer use. Do not use bleach. 1. Press chemical hose onto barbed fitting located near high pressure hose connection of pump as shown. 2. Place other end of chemical hose with filter on it into container holding chemical/cleaning solution. 3. Set multi-reg nozzle to low pressure setting, see How To Use Wand paragraph in this section. 4. After use of chemical, siphon clean water through chemical hose to rinse it and pump clean. Chemicals which remain in pump can damage it. Damage to pump due to chemicals will not be covered under warranty. NOTE: Chemicals and soap will not siphon when wand is in the high pressure setting. TO SHUT DOWN IMPORTANT: Read and understand how to shut down the pressure washer before operating. 1. If you have siphoned chemicals, siphon a bucket of clean water through the chemical hose. NOTE: Failure to do so will cause damage to the pump. 2. Turn engine off by placing the throttle control in the OFF position. NOTE: NEVER turn the water off with the engine running. 3. Turn the fuel valve to the OFF position if engine will not be restarted soon. 4. Turn water source off. 5. Pull trigger on spray gun to relieve any water pressure in hose or spray gun. 6. See Storage section in this manual for proper storage procedures. Barb fitting D25083 12- ENG BEFORE STARTING Read and understa...
