Figure 3 — Connect the Garden Hose to Water Inlet • Always wear eye protection when using this equipment or in vicinity of where equipment is in use. • Before starting the pressure washer, be sure you are wearing adequate eye protection. High pressure spray can cause paint chips or other particles to become airborne. WARNING CAUTION • Damage to equipment resulting from failure to follow this instruction will void warranty. There MUST be at least ten feet of unrestricted garden hose between the pressure washer inlet and any flow shut off device, such as a ‘Y’ shut-off connector or other convenience-type water shut-off valve. Generac Portable Products 1900 PSI Pressure Washer 8 HOW TO USE PRESSURE WASHER If you have any problems operating your pressure washer, please call the pressure washer helpline at 1-800-270-1408. How To Start Pressure Washer To start your pressure washer for the first time, follow these instructions step-by-step.This starting information also applies if you have let the pressure washer sit idle for at least a day. 1. Place pressure washer near an outside water source capable of supplying water at a flow rate greater than 3.0 gallons per minute and no less than 20 PSI at pressure washer end of garden hose. 2. Check that high pressure hose is tightly connected to spray gun and to pump. See “Preparing Pressure Washer for Use” for illustrations. 3. Make sure unit is in level position. 4. Connect garden hose to water inlet on pressure washer pump. Turn ON the water. 5. Attach adjustable nozzle extension to spray gun (Figure 4).Tighten by hand. 6. Position nozzle in low pressure mode (see “How To Use Adjustable Nozzle”) and squeeze trigger on spray gun to relieve air pressure caused by turning ON water.Water will flow out of spray gun in thin stream. Continue to hold trigger until steady stream of water occurs and no air remains in system.This will make it easier to pull start the engine. Release trigger. 7. Engage safety latch to spray gun trigger (Figure 5). 8. Start engine according to instructions given in engine owner’s manual. NOTE: Always keep the throttle lever in the “Fast” position when operating the pressure washer. How To Stop Pressure Washer • Turn engine off according to instructions given in the engine owner’s manual. • Squeeze trigger on the spray gun to relieve pressure in the hose. NOTE: A small amount of water will squirt out when pressure is released. Figure 4 — Connect Nozzle Extension to Spray Gun Safety Latch Figure 5 — Spray Gun with Safety Latch Engaged CAUTION • Always use handle to lift equipment. • NEVER pull on hoses to move equipment. Avoid fire from equipment tip over. CAUTION • Squeeze trigger on spray gun each time recoil starter is pulled and engine fails to start. Avoid injury from kickback. CAUTION • Damage to equipment resulting from failure to follow this instruction will void warranty. DO NOT run the pump without the water supply connected and turned on. Generac Portable Products 1900 PSI Pressure Washer 9 How To Use Adjustable Nozzle You now should know how to START your pressure washer and how to STOP it.The information in this section will tell you how to adjust the spray pattern and to apply detergent or other cleaning chemicals. 1. Slide nozzle forward to adjust spray to low pressure mode (Figure 6). Slide nozzle backward to achieve high pressure. 2. Point nozzle towards a firm surface and press trigger to test spray pattern (Figure 7). 3. Twisting nozzle adjusts spray pattern from a narrow pattern to a fan pattern (Figure 8). 4. For most effective cleaning, keep spray nozzle between 8 to 24 inches away from cleaning surface. 5. If spray nozzle is held too close to surface, especially using high pressure mode, damage to surface may occur. 6. DO NOT get closer than 6 inches when cleaning tires. Applying Detergent With Adjustable Nozzle IMPORTANT: Use soaps designed specifically for pressure washers. Household detergents could damage the pump. To apply detergent, follow these steps: 1. Review adjustable nozzle use. 2. Prepare detergent solution as required by job. 3. Place filter end of chemical injection hose into detergent container. Slide nozzle backward for High Pressure Mode Slide nozzle forward for low pressure mode and detergent application Figure 6 — Adjusting Nozzle for Pressure Figure 7 — Testing the Spray Pattern Figure 8 — Adjusting the Nozzle for Spray Pattern Rotate nozzle counterclockwise for fan spray pattern Rotate nozzle clockwise for narrow spray pattern CAUTION • Starting the engine without all the hoses connected and without the water turned ON will damage the pump. • Damage to equipment resulting from failure to follow this instruction will void warranty. You must attach all hoses before you start the engine. • NEVER adjust spray pattern when spraying. • NEVER put hands in front of nozzle to adjust spray pattern. A pressure washer produces a high pressure spray which increases risk of injury and damage to unit. CAUTION CAUTION Ke...
