Getting Started with Your New ROK Power Washer Setting up a new ROK power washer involves a series of critical steps to ensure both the longevity of the pump and your personal safety. Whether you have an electric or petrol model, the most vital rule is to never run the machine without water
, as this can destroy the internal seals and pistons within minutes. 1. Initial Assembly & Connections
Before powering on, you must properly assemble the high-pressure and water supply lines. Attach the Handle
: If not already attached, secure the handle to the main body using the provided screws or bolts. High-Pressure Hose
: Connect one end to the threaded water outlet on the machine and the other to the spray gun. Ensure these are hand-tight to prevent leaks. Water Supply Keep wand 6–24 inches from surface; closer increases
: Attach a standard garden hose to the water inlet. For some high-capacity petrol models, it is recommended to draw from a large water container rather than a direct tap to ensure adequate flow. Select a Nozzle
: Pull back the collar on the spray wand and insert your chosen nozzle until it clicks into place. 2. Purging Air (Crucial Step)
Trapped air can cause the machine to pulsate or fail to reach pressure. Turn on the water supply tap fully. With the power OFF , squeeze the spray gun trigger.
Hold until a steady stream of water (at normal garden hose pressure) flows from the nozzle, indicating all air has been expelled. 3. Starting the Machine
