Setup
- Unpacking: Carefully remove all components from the packaging.
- Assembly:
- Attach the handle to the main unit if it's not pre-assembled.
- Ensure the wheels are securely in place.
- Water Connection:
- Connect a garden hose to the water inlet of the pressure washer. Ensure the water filter is in place.
- Connect the other end of the garden hose to a water tap and turn on the water supply fully.
- High-Pressure Hose Connection:
- Connect one end of the high-pressure hose to the high-pressure outlet on the unit.
- Connect the other end of the high-pressure hose to the spray gun.
- Electrical Connection:
- Plug the power cord into a grounded electrical outlet.
- Priming the Pump:
- Before turning on the power, squeeze the trigger on the spray gun to allow air to escape and water to flow through the system until a steady stream emerges. This helps to prime the pump and prevent damage.
Operating Instructions
- Starting the Unit:
- Once primed, turn the power switch to the "ON" position. The motor will start.
- Allow the motor to run for a few seconds to build pressure.
- Using the Spray Gun:
- Aim the spray gun at the surface to be cleaned.
- Squeeze the trigger to activate the high-pressure spray.
- Release the trigger to stop the spray. The motor may continue to run briefly due to the automatic By-Pass valve.
- Using Detergent (if applicable):
- Fill the integrated detergent tank with an appropriate pressure washer detergent.
- The detergent suction system allows for adjustable mixing. Refer to the detergent manufacturer's instructions for dilution.
- To apply detergent, typically a low-pressure nozzle or the detergent setting on a multi-function nozzle is required.
- Using the Turbo Nozzle:
- The turbo nozzle provides a rotating jet for powerful cleaning of stubborn dirt.
- Use with caution on delicate surfaces as it delivers a very concentrated force.
- Shutting Down:
- Turn the power switch to the "OFF" position.
- Turn off the water supply.
- Squeeze the spray gun trigger to release any remaining pressure in the system.
- Disconnect the high-pressure hose and garden hose.
- Unplug the power cord.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your pressure washer.
After Each Use
- Clean the Unit: Wipe down the exterior of the pressure washer with a damp cloth.
- Flush Detergent System: If detergent was used, flush the system by running clean water through it for a few minutes.
- Drain Water: Ensure all water is drained from the pump, hoses, and spray gun, especially before storing in freezing temperatures.
- Hose and Cord Storage: Neatly wind the high-pressure hose onto the integrated reel and coil the power cord.
Periodic Maintenance
- Water Filter Cleaning: Regularly check and clean the water inlet filter to prevent debris from entering the pump.
- Nozzle Cleaning: Clear any blockages from the nozzles using the provided nozzle cleaning tool (if included) or a thin wire.
- Pump Care: For long-term storage, especially in cold climates, consider using a pump protector solution.
