6. Operating Instructions
Once assembled and connected to a water source, your pressure washer is ready for operation.
- Prime the Pump:
- Before turning on, hold the trigger down for a few seconds to allow water to flow through the system and expel any air. This helps prevent damage to the pump.
- Start the Unit:
- Press the power button or pull the trigger to start the motor. The unit will begin to spray water.
- Adjust Spray Pattern:
- Different nozzles provide different spray patterns and pressures. Select the appropriate nozzle for your cleaning task.
- The red nozzle typically provides a concentrated, high-pressure stream for tough dirt.
- The white nozzle typically provides a wider, fan-shaped spray for general cleaning or rinsing.
- Using Detergent:
- Attach the detergent foam bottle filled with a suitable pressure washer detergent.
- The unit will mix the detergent with water and apply it as foam.
- After applying detergent, remove the foam bottle and rinse the surface with clean water using a standard nozzle.
- Stopping Operation:
- Release the trigger to stop the water flow.
- For extended breaks or when finished, remove the battery pack to prevent accidental startup.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your pressure washer.
- Cleaning the Unit: After each use, wipe down the exterior of the pressure washer with a damp cloth. Do not use harsh chemicals.
