ROK Power Washer Instructions: Set Up, Prime, Use & Troubleshoot

1. Know Your Machine

A ROK washer has no motor or battery. It uses hydraulic pressure generated by stepping on a foot pedal. Key parts:

• Ensure you are using a low-pressure nozzle.
• Place the detergent suction tube (small hose usually located at the back) into your cleaning solution bottle.
• Spray the surface with detergent.
• Allow the detergent to sit for a few minutes (do not let it dry on the surface).
• Switch back to a high-pressure nozzle to rinse.

Rok Power Washer – Quick Start & Safety Instructions

1. Assembly (if new)

1. Connect to a Water Source: Attach the water inlet to a standard garden hose (not included). Ensure the hose is securely connected to prevent leaks.
2. Plug in the Power Cord: Insert the power cord into a grounded outlet. Make sure the outlet is rated for the power washer's specifications (check your user manual).
3. Turn On the Power Washer: Press the power button to start the machine. The Rok Power Washer will begin to build pressure.
4. Adjust the Pressure: Use the pressure control dial to adjust the pressure to your desired level. Be cautious not to exceed the recommended pressure for your surface.
5. Spray Nozzle Tips: Choose the correct nozzle tip for your cleaning task:

   Part 1: The "First Start" Ritual (The Air Demon)

   The Manual Says: "Connect water, turn on, squeeze trigger." The Reality: The pump screams like a dying banshee for 15 seconds. The Fix (Not in the manual): Before connecting the high-pressure hose, run water through the gun without the nozzle attached. This purges the "air lock" that plagues 70% of Rok units out of the box. Think of it as giving the machine a glass of water before asking it to run a marathon. rok power washer instructions

   Lance & Nozzle: Insert the lance into the spray gun and twist 1/4 turn to lock. Attach your chosen nozzle (e.g., green for general cleaning, red for high-intensity) until it clicks. ROK Power Washer Instructions: Set Up, Prime, Use
