5. Operating Instructions

Follow these steps for safe and effective operation of your Easy-Kleen pressure washer.

5.1 Starting the Unit

1. Ensure the water supply is turned ON and fully open.
2. Squeeze the spray gun trigger to purge air from the pump and hose until a steady stream of water flows out. Release the trigger.
3. Refer to the engine manufacturer's manual for specific starting procedures (choke, throttle, recoil start).
4. Once the engine starts, allow it to warm up for a few minutes.

5.2 Hot Water Operation

1. With the engine running and water flowing, turn the burner ON/OFF switch to the 'ON' position.
2. Adjust the thermostat to the desired water temperature. The burner will ignite and begin heating the water.
3. Allow a few moments for the water to reach the set temperature before beginning cleaning.

5.3 Applying Detergent (Downstream Injection)

1. Ensure the black soap nozzle is installed on the wand. This nozzle operates at low pressure, allowing the chemical injector to draw detergent.
2. Place the chemical injector hose into a container of pressure washer safe detergent.
3. Squeeze the spray gun trigger. The unit will draw detergent and mix it with the water.
4. Apply detergent to the cleaning surface. Allow it to dwell as recommended by the detergent manufacturer.
5. To rinse, remove the chemical injector hose from the detergent and switch to a high-pressure nozzle (e.g., 15°, 25°, or 40°).

5.4 Shutting Down the Unit

1. If using hot water, turn the burner ON/OFF switch to 'OFF'.
2. Turn off the engine (refer to the engine manual).
3. Turn off the water supply.
4. Squeeze the spray gun trigger to relieve any remaining pressure in the system.
5. Disconnect the garden hose and high-pressure hose.
6. Drain any remaining water from the pump and hoses, especially in freezing conditions.

6. Maintenance

Regular maintenance is crucial for the longevity and optimal performance of your pressure washer.

6.1 After Each Use

• Flush the pump with clean water to remove any chemical residues.
• Clean the exterior of the unit.
• Inspect hoses, connections, and nozzles for wear or damage.

6.2 Engine Maintenance

Refer to the engine manufacturer's manual for detailed maintenance schedules, including:

• Oil changes.
• Air filter cleaning/replacement.
• Spark plug inspection/replacement.
• Fuel system maintenance.

6.3 Pump Maintenance

• Check pump oil level regularly and change as recommended (typically every 50-100 hours of operation). Use non-detergent pump oil.
• Inspect inlet filter for debris and clean if necessary.
• Periodically check for leaks around seals and fittings.

6.4 Burner and Coil Maintenance

• Ensure adequate burner fuel supply.
• Periodically inspect the heating coil for soot buildup. If excessive soot is present, professional cleaning may be required.
• Check the burner nozzle and electrodes for wear or damage.

6.5 Winterization

In freezing climates, proper winterization is essential to prevent damage to the pump and coil:

• Drain all water from the pump, hoses, and coil.
• Introduce an RV antifreeze solution into the pump and coil until it exits the high-pressure outlet.
• Store the unit in a heated area if possible.
