WARNING HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY. FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS. Read and understand all instruction manuals before operating equipment. FLUID INJECTION HAZARD General Safety This pressure washer generates very high fluid pressure. Spray from the gun, leaks or ruptured components can inject fluid through your skin and into your body and cause extremely serious bodily injury including the need for amputation.
GROUNDING INSTRUCTIONS This product must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This equipment is equipped with a cord having an equipment–grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
HOSE SAFETY High pressure fluid in the hoses can be very dangerous. If the hose develops a leak, split or rupture due to any kind of wear , damage or misuse, the high pressure spray emitted from it can cause a fluid injection injury or other serious bodily injury or property damage. ALL FLUID HOSES MUST HA VE STRAIN RELIEFS ON BOTH ENDS. The strain reliefs help protect the hose from kinks or bends at or close to the coupling, which can result in hose rupture.
INSTALLATION HIGH PRESSURE HOSE CONNECTION 2 x 1/2” NPT(f) PUMP OIL LEVEL INDICATOR WINDOW PUMP DIPSTICK WATER CONNECTION 2 x 1” NPT(f) Water supply tank, gun & wand assembly, hose assembly and motor starter are not included. Figure 1 Check for Shipping Damage Check the unit for any damage that may have occurred in shipping. Notify the carrier immediately if there is any damage.
STARTUP Use this procedure whenever starting the pressure washer to help insure that the unit is ready to operate and starting is done safely. 6. ALWAYS observe the following CAUTIONS to avoid costly damage to the pressure washer. 1. Check the oil level. Pump: Add SAE 20 or 30 weight non–detergent oil as necessary. 2. Turn on the water supply. CAUTION Never run the unit dry . Costly damage to the pump will result. Always be sure the water supply is completely turned on before operating. 3.
Trigger Safety Latch WARNING To reduce the risk of serious bodily injury , including fluid injection, splashing in the eyes or on the skin, ALWAYS engage the trigger safety latch whenever spraying stops, even for a moment. In the engaged position, the trigger safety latch prevents the gun from being triggered accidentally by hand or if it is dropped or bumped. Be sure the latch is pushed fully down when engaging it or it cannot prevent the gun from being triggered. See Figure 2.
SHUTDOWN, FLUSHING AND STORAGE WARNING PRESSURE RELIEF PROCEDURE To reduce the risk of serious bodily injury , including fluid injection and splashing in the eyes, or on the skin, always follow this procedure whenever you stop spraying for more than 10 minutes, when shutting down, and before checking or repairing any part of the system. 1.
