OPERATING INSTRUCTIONS Compare the illustrations with your unit to familiarize yourself with the location of various controls and adjustments. Save this manual for future reference. Engine High Pressure Pump Spray Gun High Pressure Hose Quick Connect Spray Wand BASIC ELEMENTS OF A PRESSURE WASHER BASIC ELEMENTS OF AN ENGINE High Pressure Pump: Increases the pressure of the water supply. Refer to the engine manual for location and operation of engine controls.
PRESSURE WASHER TERMINOLOGY (continued) PRESSURE WASHER OPERATING FEATURES Bypass Mode: Allows water to re-circulate within pump when the gun trigger is not pulled. Allowing the unit to run for more than two minutes without the gun trigger pulled could cause overheating and damage to the pump. Thermal Thermal Relief Valve: Relief When the temperature Valve inside the pump rises too high the valve will open and release a gush of water in an effort to lower the temperature inside the pump.
READ AND UNDERSTAND ALL WARNINGS BEFORE STARTING UNIT When using the high pressure setting, DO NOT allow the high pressure spray to come in contact with unprotected skin, eyes, or with any pets or 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 injury. Leaks caused by loose fittings or worn or damaged hoses can result in injection injuries.
Changing Nozzles on Spray Wand 2. DO NOT attempt to change nozzles while pressure washer is running. Turn engine off before changing nozzles. 1. Pull quick connect coupler back and insert nozzle. 2. Release quick connect coupler and twist nozzle to make sure it is secure in coupler. Risk Of Injury. Ensure nozzle is completely inserted in QC socket, and QC snap ring is fully engaged (forward) before squeezing gun trigger. Risk of injection or injury to person.
STARTING (continued) 4. 5. 9. Depress trigger on gun to start water flow. NOTE: Stand on a stable surface and grip gun/spray wand firmly with both hands. Expect the gun to kick when triggered. 10. Release trigger to stop water flow. 11. Adjust spray for the task being performed by changing quick connect nozzle. See How To Use Spray Wand instructions in this section. Connect water source to pump inlet. NOTE: Water source must provide a minimum of 5 gallons per minute at 20 PSI.
PUMP 4. Remove the high-pressure nozzle from the spray wand. Remove any obstructions with the nozzle cleaning tool provided and backflush with clean water. 5. Direct water supply into spray wand to backflush loosened particles for 30 seconds. Reassemble the nozzle to the wand. Reconnect spray wand to gun and turn on water supply. Start pressure washer and place spray wand into high pressure setting to test. NOTE: The pump was filled with oil at the factory. 1.
STORAGE 5. ENGINE Consult the Engine Owners Manual for the manufacturer's recommendations for storage. PUMP The manufacturer recommends using a pump protector/winterizer when storing the unit for more than 30 days and/or when freezing temperatures are expected. If a pump protector/winterizer is not available, *RV antifreeze needs to be run through the pump as outlined in the steps below.
TROUBLE SHOOTING GUIDE CAUSE PROBLEM Engine will not start (see Engine Manual for further engine troubleshooting) No or low pressure (initial use) CORRECTION No fuel. Add Fuel. Low oil Add required amount of oil. Pressure builds up after two pulls on the recoil starter or after initial use. Squeeze gun trigger to relieve pressure. Choke lever in the “No Choke” position. Move choke to the “Choke” position. Spark plug wire not attached. Attach spark plug wire.
PROBLEM Will not draw chemicals No or low pressure (after period of normal use) Water leaking at gun/spray wand connection Water leaking at pump Oil leaking at pump CAUSE CORRECTION Spray wand not in low pressure. See How to Use Spray Wand paragraph in the Operation Section. Chemical filter clogged. Clean filter. Chemical screen not in cleaning solution. Make sure end of chemical hose is fully submerged into cleaning solution. Chemical too thick. Dilute chemical.
