OPERATING INSTRUCTIONS READ THIS OWNER’S MANUAL AND SAFETY RULES BEFORE OPERATING YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with the location of various controls and adjustments. Save this manual for future reference. Quick Connect Nozzles Engine Quick Connect Spray Wand Spray Gun High Pressure Hose High Pressure Pump Surface Cleaning Guide BASIC ELEMENTS OF A PRESSURE WASHER High Pressure Pump: Increases the pressure of the water supply.
BASIC ELEMENTS OF ENGINE Refer to the engine manual for location and operation of engine controls. Choke Control: Opens and closes carburetor choke valve Starter Grip: Pulling starter grip operates recoil starter to crank engine. Engine Switch: Enables and disables ignition system. PRESSURE WASHER TERMINOLOGY 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.
TO USE SPRAY WAND Your pressure washer is equipped with five spray nozzles. Each nozzle is color coded and delivers a specific spray pattern for a particular cleaning purpose. The size of the nozzle determines the size of the fan spray and the pressure out of the nozzle. The 0º, 15º, 25º, and 40º nozzles are high pressure nozzles. The chemical nozzle is a low pressure nozzle. The nozzles are housed in receptacles on the panel of the pressure washer handle.
HOW TO APPLY CHEMICALS AND CLEANING SOLVENTS Applying chemicals or cleaning solvents is a low pressure operation. NOTE: Use only soaps and chemicals designed for pressure washer use. Do not use bleach. To Apply chemicals: 1. Press chemical hose onto barbed fitting located near high pressure hose connection of pump as shown. Barb fitting 2. Place other end of chemical hose with filter on it into container holding chemical/cleaning solution.
STARTING Prior to starting, refer to your engine manual for proper starting procedures for your engine type. 1. In a well ventilated outdoor area add fresh, high quality, unleaded gasoline with a pump octane rating of 86 or higher. Do not overfill. Wipe up spilled fuel before starting the engine. Refer to Engine Owners Manual for correct procedure. 2. Check engine oil level. See Engine Owners Manual for correct procedure. NOTE: There will be a slight amount of oil in the engine from factory testing. 3.
MAINTENANCE When performing maintenance, you may be exposed to hot surfaces, water pressure, or moving parts that can cause serious injury or death! Before performing any maintenance or repair, disconnect spark plug wire, let engine cool and release all water pressure. The engine contains flammable fuel. DO NOT smoke or work near open flames while performing maintenance. To ensure efficient operation and longer life of your pressure washer, a routine maintenance schedule should be prepared and followed.
HOW TO CLEAN THE WATER INLET FILTER This screen filter should be checked periodically and cleaned if necessary. 1. 2. Remove filter by grasping end and removing it from water inlet of pump as shown. Filter Screen Clean filter by flushing it with water on both sides. 3. Re-insert filter into water inlet of pump. NOTE: Cone side faces out. NOTE: Do not operate pressure washer without filter properly installed.
STORAGE ENGINE Consult the Engine Owners Manual for the manufacturer's recommendations for storage. PUMP 1. Drain all water from high pressure hose, coil it, and store it in cradle of the pressure washer handle. 2. Drain all water from spray gun and spray wand by holding spray gun in a vertical position with nozzle end pointing down and squeezing trigger. Store in gun/hose holder. 3.
TROUBLE SHOOTING GUIDE PROBLEM Engine will not start (see Engine Manual for further engine troubleshooting) No or low pressure (initial use) CAUSE CORRECTION No fuel. Add Fuel. 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) 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 chemical Ensure end of chemical hose is fully submerged into chemical. Chemical too thick. Dilute chemical. Chemical should be the same consistency as water. Pressure hose is too long Lengthen water supply hose instead of high pressure hose.
