1. Unpacking: Carefully remove the high-pressure washer and all accessories from the packaging. Inspect for any shipping damage.
2. Accessory Connection: Connect the high-pressure hose to the machine's outlet and the EASY!Force high-pressure gun. Utilize the EASY!Lock quick-release fasteners for secure and fast connections.
3. Water Supply: Connect a suitable water supply hose to the machine's inlet. Ensure the water supply is clean and has adequate pressure.
4. Power Connection: Connect the power cord to a grounded electrical outlet that meets the machine's power requirements (three-phase).

Operating Instructions

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

1. Start-up: Turn on the water supply completely. Ensure the high-pressure gun is pointed in a safe direction. Turn on the main power switch of the machine.
2. Priming: Squeeze the trigger on the high-pressure gun to allow air to escape and water to flow steadily. This primes the pump.
3. Operation: Once primed, the machine will build pressure. The EASY!Force high-pressure gun is designed to reduce holding force, making operation less fatiguing. Direct the spray lance at the surface to be cleaned, maintaining an appropriate distance to avoid damage.
4. Adjusting Pressure: If your model features Servo Control, adjust the pressure directly on the spray lance or machine as needed for different cleaning tasks.
5. Detergent Application: If using detergent, activate the detergent function on the machine or lance. Apply detergent evenly and allow it to dwell as per instructions, then rinse with clear water.
6. Shut-down: Release the trigger on the high-pressure gun. Turn off the main power switch. Turn off the water supply. Squeeze the trigger again to release any remaining pressure in the system.

  • Clean the exterior of the machine with a damp cloth.
  • Inspect the high-pressure hose and power cord for any signs of damage.
• Nozzle Cleaning: Regularly check and clean the nozzle to prevent blockages and maintain spray pattern integrity.
• Water Filter: Inspect and clean the water inlet filter periodically to prevent debris from entering the pump.
• Frost Protection: If storing in an area where temperatures may drop below freezing, ensure the machine is completely drained of water or protected with anti-freeze solution to prevent damage.
• Storage: Store the high-pressure washer in a dry, protected area. The upright design and large wheels facilitate easy maneuvering and storage.
