   Connect one end of the high-pressure hose to the outlet on the pressure washer unit and the other end to the inlet on the high-pressure gun. Ensure all connections are tight to prevent leaks.
3. Attach the Lance: Connect the extension lance to the high-pressure gun. Twist or click into place as per the design.
4. Connect Water Supply: Attach a garden hose (not supplied) to the water inlet on the pressure washer. It is recommended to use the supplied water filter between the garden hose and the pressure washer inlet to protect the pump from debris. Ensure the water supply is turned on fully before starting the unit. The pressure washer requires a continuous and adequate water supply.
5. Connect Power: Plug the power cable into a suitable grounded electrical outlet. Ensure the power switch on the unit is in the "OFF" position before plugging it in.

Operating Instructions

1. Purge Air from the System: Before starting the motor, squeeze the trigger on the high-pressure gun to allow water to flow through the system and expel any trapped air. Continue until a steady stream of water emerges from the nozzle.
2. Start the Pressure Washer: Turn the power switch to the "ON" position. The motor will start.
3. Begin Cleaning: Aim the nozzle at the surface to be cleaned, keeping a safe distance. Squeeze the trigger to start the high-pressure water flow. Adjust the distance and angle for optimal cleaning without damaging the surface.
4. Stopping Operation: To temporarily stop, release the trigger. The motor may continue to run or cycle on/off depending on the model's auto-stop feature. To completely stop, turn the power switch to "OFF" and release the trigger.
5. After Use: Turn off the power switch and disconnect the power cable. Turn off the water supply. Squeeze the trigger on the gun to release any residual pressure in the system. Disconnect the high-pressure hose and garden hose.
