When you release spray gun trigger and engine is still running, you are in bypass mode. When unit is in bypass mode, water circulating inside the pump begins to heat up. 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. If pressure washer is operated without an adequate water supply or operated for more than two (2) minutes without depressing the spray gun trigger, the pump will overheat and be seriously damaged. Any damage to pump due to these causes will not be covered under warranty. 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. DO NOT allow your unit to operate in bypass mode for more than two minutes at any time. Overheating of pump will cause damage to pump. PRESSURE ADJUSTMENT DO NOT attempt to increase pump pressure. A higher pressure setting than the factory set pressure will damage pump. The pressure output of the pump is preset at the factory to achieve optimum pressure and cleaning. If you need to lower the pressure, it can be accomplished by one of these three methods: 1. Back away from the surface being cleaned. The farther away you are, the less pressure is delivered to the surface being cleaned. 2. Adjust the pressure regulator knob on the pump. a. Turn the pressure regulator knob counterclockwise. b. Once you have finished using your pressure washer, return the pressure regulator knob to its original position by turning it clockwise until it stops. DO NOT try to turn pressure regulator knob past the built-in stop or damage to pump will result Pressure Regulator Knob 3. Reduce the speed of the gasoline engine (RPM). Slow engine down and water pressure will go down with it. SPRAY NOZZLES 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. 9 — ENG D20249 PRESSURE WASHER BASICS OPERATION PRESSURE WASHER BASICS OPERATION The nozzles are housed in receptacles on the panel of To change nozzles on the wand: the pressure washer handle. Color squares on the 1. Pull quick connect coupler back and insert nozzle. panel identify nozzle location and spray pattern. 2. Release quick connect coupler and twist nozzle to make sure it is secure in coupler. Quick Connect Coupler NOTE A nozzle is easier to remove from its receptacle if it is pushed from underneath while it is being pulled from above. RISK OF INJECTION OR INJURY TO PERSON. DO NOT DIRECT DISCHARGE STREAM TOWARD PERSONS. WHEN USING THE HIGH PRESSURE NOZZLES, DO NOT ALLOW THE JET-LIKE SPRAY TO COME IN CONTACT WITH UNPROTECTED SKIN, EYES, OR WITH ANY PETS OR ANIMALS. SERIOUS IN JURY CAN OCCUR. 0O nozzle - Red. This nozzle delivers a pinpoint stream and is extremely powerful. It covers a very small area of cleaning. This nozzle should only be used on surfaces that can withstand this high pressure such as metal or concrete. Do not use on wood. 15O nozzle - Yellow. This nozzle delivers a powerful 15 degree spray pattern for intense cleaning of small areas. This nozzle should only be used on areas that can withstand the high pressure from this nozzle. 25O nozzle - Green. This nozzle delivers a 25 degree spray pattern for intense cleaning of larger areas. This nozzle should only be used on areas that can withstand the pressure from this nozzle. 40O nozzle - White. This nozzle delivers a 40 degree spray pattern and a less powerful stream of water. It covers a wide area of cleaning. This nozzle should be used for most general cleaning jobs. Chemical nozzle - Black. This nozzle is used to apply chemicals or cleaning solutions. It has the least powerful stream. CHANGING NOZZLES DO NOT attempt to change nozzles while pressure washer is running. Turn engine off before changing nozzles. HOW 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. To siphon chemicals: 1. Press chemical hose onto barbed fitting located near high pressure hose connection of pump as shown. Barbed Fitting 2. Place other end of chemical hose with filter on it into container holding chemical/cleaning solution. 3. Install low pressure (black) nozzle into quick connect fitting of wand as shown. Larger Hole 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 t...
