5. Operating Instructions

Follow these steps for safe and effective operation.

1. Pre-Operation Checks:
   • Verify engine oil and fuel levels.
   • Check all hose connections for tightness.
   • Ensure the water supply is turned on and flowing to the machine.
2. Starting the Engine:
   • Follow the engine manufacturer's instructions for starting (choke, throttle, pull cord/electric start).
   • Allow the engine to warm up for a few minutes.
3. Engaging the Pump:
   • Once the engine is running smoothly, slowly open the water supply valve completely.
   • Ensure water is flowing through the system before engaging the pump to prevent damage.
4. Jetting Procedure:
   • With the engine running and water flowing, slowly feed the jetting hose into the drain opening.
   • Once the nozzle is inside the pipe, activate the high-pressure water flow.
   • Use the Vibra-pulse® feature as needed to help the hose navigate tight bends and obstructions.
   • Advance the hose slowly, allowing the water jet to clear blockages.
   • Retract the hose slowly, ensuring the pipe is thoroughly cleaned.
5. Pressure Washing (Optional):
   • If equipped, switch the control panel knob to the pressure washing setting.
   • Attach the spray wand with trigger to the appropriate outlet.
   • Direct the spray away from people and sensitive surfaces.
6. Shutdown Procedure:
   • Turn off the high-pressure water flow.
   • Turn off the engine.
   • Turn off the main water supply.
   • Relieve any residual pressure in the system by briefly squeezing the trigger on the spray wand or opening a valve.
   • Disconnect hoses and drain water from the system, especially in freezing temperatures.
