Setup
1. Assembly
- Attach Handles: Secure the dual handles to the main frame using the provided hardware.
- Install Wheels: Attach the pneumatic tires to the axle.
- Connect High-Pressure Hose: Connect one end of the 50-foot non-marking hose to the pump's high-pressure outlet and the other end to the spray gun. Ensure connections are tight.
- Connect Wand: Attach the extension wand to the spray gun.
2. Fuel and Oil
- Engine Oil: Fill the engine crankcase with the recommended engine oil (refer to Honda GX390 engine manual for specific type and capacity). Do not overfill.
- Fuel: Fill the fuel tank with fresh, unleaded gasoline. Do not use E85 or E15 fuel.
3. Water Connection
- Garden Hose: Connect a standard garden hose (minimum 5/8-inch diameter) to the pump's water inlet. Ensure the garden hose is free of kinks and has a steady water supply.
- Inlet Filter: Verify the 50 mesh inlet filter is clean and properly installed to protect the pump from debris.
- Purge Air: Before starting the engine, turn on the water supply and squeeze the spray gun trigger to purge air from the pump and hose until a steady stream of water emerges.
Operating Instructions
1. Pre-Start Checklist
- Check engine oil level.
- Check fuel level.
- Ensure all hose connections are secure.
- Verify water supply is connected and turned on.
- Purge air from the system by squeezing the spray gun trigger.
- Select and attach the desired quick-connect nozzle tip.
2. Starting the Engine
- Turn the engine switch to the "ON" position.
- Open the fuel valve.
- Move the choke lever to the "CLOSED" position (if engine is cold).
- Pull the starter rope slowly until resistance is felt, then pull quickly and firmly.
- Once the engine starts, gradually move the choke lever to the "OPEN" position.
3. Using the Pressure Washer
- Nozzle Selection: Choose the appropriate quick-connect nozzle tip for your task. Narrower angles (e.g., 0°, 15°) provide higher impact for tough stains, while wider angles (e.g., 40°, soap nozzle) are for general cleaning or applying detergent.
- Pressure Adjustment: The unit features an easy-to-adjust pressure unloader. Turn the knob to increase or decrease pressure as needed.
- Operation: Hold the spray gun firmly with both hands. Maintain a safe distance from the surface being cleaned. Always start spraying away from the surface and move towards it.
4. Shutting Down
- Release the spray gun trigger.
- Turn off the engine switch.
- Turn off the water supply.
- Squeeze the spray gun trigger to release any remaining pressure in the system.
- Disconnect the garden hose and high-pressure hose.
