2. Start Up ALWAYS use this start up procedure to ensure that the unit is started safely and properly. If water has frozen in the pressure washer, thaw the pressure washer in a warm room before starting. DO NOT pour hot water on or into the pump; internal parts will be damaged. 1. Check engine oil levels. Add oil as necessary. 2. Check fuel level. Add unleaded gasoline (rated 86 octane or higher) as required. DO NOT refuel a hot engine. Refueling a hot engine could cause a fire. Use only fresh, clean regular or unleaded gasoline. Close the fuel shutoff valve during refueling. 3. Attach a garden hose to the inlet side of the pump and connect it to the water supply. Use a hose with an internal diameter (I.D.) of 5/8 in. (1.58 cm) and a length of 50 ft. (15 m) or less. Some local plumbing codes require backflow prevention when connecting to a fresh water supply. Install a backflow preventer upstream from the pump if necessary. a. If inlet water pressure is over 100 psi, install a regulating water valve at the garden hose connection. b. Do not exceed 100° F (38° C) inlet water temperature. NOTE: The inlet water supply must have a minimum flow rate of 5 gpm (19 lpm). 4. Turn the water supply ON. Never run the unit dry. Be sure the water supply is completely turned on before operating the unit. 5. Trigger the gun until water sprays from the tip indicating that all air is purged from the system. Set the trigger safety latch. 6. Open the fuel shutoff valve by turning the lever to the right/“ON” position. Close the choke (if the engine is cold) by moving the choke lever fully to the left. Move the throttle fully to the left to the “Run” or “Rabbit” position. Turn the ON/OFF swirch to the “ON” position. Figure 10 - Throttle 6 PW2770, PW3270, and PW4070 Operation (Continued) 7. Start the engine: Unlock the trigger safety latch on the gun. Grasp the starter rope and brace one foot on the chassis. While squeezing the trigger on the gun, pull the starter rope rapidly and firmly. Continue holding the rope as it returns. Repeat these steps until the engine starts. When pulling the starter rope, make sure to keep your hand and arm clear of the engine and cart components. Never let the starter rope return by itself. Doing so could jam the recoil system. 8. If the engine does not start after two or three pulls or if the rope is hard to pull, squeeze the gun trigger to release the pressure that has built up in the high pressure hose. Repeat Steps 7 and 8 until the engine starts. 3. Initial High Pressure Rinse Spray the cleaning surface with water to clear off any dirt or grime that may have collected on the surface. Doing so allows the detergent to attack the deep down dirt that has worked its way into the cleaning surface. After the engine starts, trigger the gun 3 to 5 times to get any trapped air out of the system. After the spray becomes constant, you may need to adjust the pressure. Counterclockwise: Lower pressure Clockwise: Higher pressure Figure 11 - Camshaft pump pressure adjustment PRESSURE ADJUSTMENT Please refer to your CAT pump manual for specific pressure adjustment details. ADJUSTING THE SPRAY FAN ANGLE Five quick connect tips are included with this pressure washer. The tips have a range of spray fan angles, ranging from 0°, narrow high impact, to a 65° wide fan spray. Pressure can also be adjusted by moving closer or further away from the cleaning surface and by adjusting the spray fan angle as shown. Figure 12 - Narrow high impact stream Figure 13 - Wide fan pattern ANGLE TO THE CLEANING SURFACE When spraying water against a surface, you can generate maximum impact by striking the surface head on. However, this type of impact can cause dirt particles to embed in the surface and can prevent the desired cleaning action. The optimum angle for spraying water against a cleaning surface is 45 degrees. Spray water against a surface at a 45 degree angle to achieve the most beneficial impact force and to efficiently remove debris. DISTANCE FROM CLEANING SURFACE The distance between the spray tip and the cleaning surface is another factor that affects the impact force of the water. The impact force of the water increases as the tip is moved closer to the surface. Figure 14 - Optimum angle to cleaning surface HOW TO AVOID DAMAGING SURFACES Damage to cleaning surfaces occurs because the impact force of the water exceeds the durability of the surface. You can vary the impact force by controlling the spray tip angle to the cleaning surface and the distance from the cleaning surface and by changing the spray tip. NEVER use a narrow high impact stream on a surface that is susceptible to damage. Avoid spraying windows with a narrow high impact stream. Doing so may break the window. The most sure way to avoid damaging surfaces is to follow these steps: 1. Before triggering the gun, make sure the quick connect tip you are using is appropriate for the application. 2. Place the spray tip approximately 45 feet (1,22...
