4. Operating Instructions
Follow these steps for safe and effective operation of your pressure washer.
- Pre-Operation Check: Verify all fluid levels (gasoline, engine oil, burner fuel). Ensure all hoses are securely connected and free from leaks. Check the water inlet filter for cleanliness.
- Water Supply: Turn on the water supply completely to the pressure washer. Squeeze the trigger on the spray gun to purge air from the system until a steady stream of water flows out.
- Starting the Engine: Ensure the engine throttle is set to the 'FAST' position. Turn the ignition key to start the 13 HP Honda engine. Allow the engine to warm up for a few minutes.
- Engaging Hot Water (Burner): To activate the hot water function, ensure the burner fuel tank is adequately filled. Flip the burner switch to the 'ON' position. The burner will ignite, and hot water will be produced after a short delay.
- Using the Wand and Nozzles: Select the appropriate nozzle for your cleaning task. Start cleaning from a distance and gradually move closer to the surface, maintaining a safe distance to avoid damage.
- Chemical Injection: For chemical application, attach the soap nozzle and ensure the downstream chemical injection system is properly connected to your detergent container. The system will draw detergent at low pressure.
- Shutting Down: First, turn off the burner switch. Allow the system to cool down by running cold water through it for a few minutes. Then, turn off the engine ignition. Finally, turn off the water supply and squeeze the trigger to relieve any remaining pressure in the system.

5. Maintenance
Regular maintenance ensures optimal performance and extends the life of your pressure washer.
- Engine Oil: Check engine oil before each use. Change oil every 50 hours of operation or seasonally. Refer to the Honda engine manual for specifics.
- Pump Oil: Check pump oil level regularly. Change pump oil every 200 hours of operation or annually. Use non-detergent pump oil.
- Fuel Filter: Inspect and clean or replace the fuel filter as needed, especially if fuel delivery issues occur.
- Water Inlet Filter: Clean the water inlet filter screen before each use to prevent debris from entering the pump.
- Nozzle Cleaning: Clean clogged nozzles using the provided nozzle cleaning tool.
- Burner Maintenance: Periodically inspect the burner coil for soot buildup. Consult a qualified technician for burner nozzle and ignition system maintenance.
- Winterization: In freezing temperatures, drain all water from the pump, hoses, and heating coil. Use a pump saver or antifreeze solution to protect internal components from freezing damage.
