Operating Instructions
1. Starting the Unit
Before starting, ensure the water supply is turned on and the high-pressure hose is connected to the spray wand. Squeeze the trigger on the spray wand to purge air from the system until a steady stream of water emerges. Then, turn the power switch to the 'ON' position.
2. Adjusting Spray Pattern and Pressure
The adjustable nozzle allows you to easily switch between an intense jet and a gentle spray. Twist the nozzle at the end of the spray wand to achieve the desired spray pattern and pressure for your cleaning task.
