Engage trigger safety latch. 6. If spray tip or hose is completely clogged, or pressure has not been fully relieved after following steps above: Disengage trigger safety latch and trigger gun to relieve pressure. Wrap rag around hose end coupling and VERY SLOWLY loosen coupling to relieve pressure gradually, then loosen completely. Now clear tip or hose. Startup 1. Check oil levels. . Engine: Add SAE 30 or 10W–30 weight detergent oil as necessary. . Pump: Add SAE 20 or 30 weight non–detergent oil. NOTE: This pressure washer is equipped with a low–oil sensor that shuts the engine off if the oil level falls below a certain level. If the unit stops unexpectedly, check both the oil and the fuel levels. Check the oil level each time the unit is refueled. 2. Check fuel level. WARNING FIRE HAZARD Do not refuel a hot engine. Refueling a hot engine could cause a fire. Use only fresh, clean regular or unleaded gaso line. Close fuel shutoff valve during refueling. 3. Turn on the water supply. CAUTION Never run unit dry. Costly damage to pump will result. Always be sure water supply is sufficient before operating. 4. Trigger the gun until water sprays from the tip indicating that the air is purged from the system. 5. Open the fuel shutoff valve. Be sure the spark plug ignition cables are pushed firmly onto the spark plugs. Put the ignition shutoff switch in the “on” position and the throttle in the “run” position. 6. Start the engine. NOTE: For easier starting, have one person start the pressure washer while another person triggers the spray gun. If the engine is cold, completely close the engine choke. Press the start button. In cool weather, the choke may have to be kept closed for 10 to 30 seconds before opening it to keep the engine running. Otherwise, open the choke as soon as the engine starts. If the engine is warm, leave the choke open or partially closed. Start the engine as described in the preceding paragraph. When the engine starts, be sure to open the choke completely. 7. ALWAYS engage the gun’s trigger safety latch whenever you stop spraying, even for a moment, to reduce the risk of fluid injection or splashing in the eyes or on the skin if the gun is bumped or triggered accidentally. 8. ALWAYS observe the following CAUTIONS to avoid costly damage to the pressure washer. 6 308532 Operation CAUTION Pressure washer is equipped with a thermal relief valve. If pressure washer is operated without spraying for an extended period (approximately 10 minutes) the valve will expel hot water. Do not operate pressure washer with inlet water screen removed. Keep screen clean. Screen keeps abrasive sediment out of pump, Abrasive sediment can clog pump or damage cylinders. 04612 Do not pump caustic materials; such materials may corrode pump components. 9. See the chemical injector or sandblaster kit manual for detailed cleaning information if these accessories are used. Trigger Safety Latch WARNING To reduce risk of serious bodily injury, including fluid injection, splashing in eyes or on skin, always engage trigger safety latch when spraying is stopped, even for a moment. In engaged position, trigger safety latch prevents gun from being triggered accidentally by hand or if dropped or bumped. Be sure to push down latch fully to engage it. If latch not fully engaged, gun can accidentally trigger. See Figures 2a and 2b.

Remove the old tip and/or install a new one, and then release the ring. See Figure 3. 4. Be sure the tip is secure before starting to spray again. 5. Tip holding holes are provided on the chassis. CAUTION To avoid blowing o-ring out of quick coupler, due to high pressure in system, never operate pressure washer without tip securely mounted in quick coupler. 04929 Figure 3 A B 8 308532 Shutdown, Flushing, and Storage CAUTION Do not expose pressure washer to freezing temperatures or allow water to freeze in pressure washer components. If water freezes in the pressure washer, thaw it in a warm room before you try to start it. Do not pour hot water on or into the pump; it may crack the ceramic plungers! . Do not store unit outside where it will be exposed to rain, dirt or adverse weather conditions. .
