4. Setup

1. Unpacking and Inspection: Carefully remove the water jet from its packaging. Inspect all components for any signs of shipping damage. Report any damage to your supplier immediately.
2. Wheel Assembly (if required): Attach the wheels to the frame using the provided hardware. Ensure they are securely fastened.
3. Engine Preparation:
   • Fill the engine with the recommended type and amount of oil (refer to the engine manufacturer's manual for specifics).
   • Fill the fuel tank with fresh, unleaded gasoline. Do not overfill.
4. Water Supply Connection: Connect a standard garden hose from a reliable water source to the water inlet fitting on the pump. Ensure the connection is tight to prevent leaks.
5. High-Pressure Hose Connection: Connect one end of the high-pressure hose to the pump's high-pressure outlet. Connect the desired nozzle to the other end of the hose. Ensure all connections are secure.
6. Nozzle Selection: Choose the appropriate nozzle for the task. Different nozzles are designed for various types of blockages and pipe sizes.

5. Operating Instructions

1. Before Starting:
   • Ensure all connections are secure and free of leaks.
   • Open the water supply valve completely to allow water to flow through the pump and hose, purging any air.
   • Check engine oil and fuel levels.
2. Starting the Engine:
   • Set the engine switch to the 'ON' position.
   • Move the choke lever to the 'CHOKE' position (for cold starts).
   • Pull the recoil starter handle firmly until the engine starts.
   • Once the engine starts, gradually move the choke lever to the 'RUN' position.
3. Jetting Operation:
   • Slowly feed the high-pressure hose into the drain or pipe.
   • Maintain a firm grip on the hose and guide it carefully.
   • Do not force the hose. If resistance is met, retract slightly and try again.
   • The rear-facing jets on the nozzle propel it forward and flush debris backward.
4. Shutting Down:
   • Turn off the engine using the engine switch.
   • Close the water supply valve.
   • Relieve any residual pressure in the system by briefly activating the trigger (if applicable) or disconnecting the hose carefully.
   • Drain any remaining water from the pump and hoses, especially in freezing conditions.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your water jet.

• After Each Use:
  • Clean the exterior of the unit.
  • Inspect hoses and nozzles for wear or damage.
  • Drain water from the pump and hoses.
• Engine Maintenance: Refer to the engine manufacturer's manual for specific service intervals for oil changes, air filter cleaning/replacement, and spark plug inspection/replacement.
• Pump Maintenance: Check pump oil levels (if applicable) and change according to manufacturer recommendations. Inspect pump seals and valves periodically.
• Nozzle Cleaning: Use the provided cleaning tool to clear any debris from the nozzle orifices. Clogged nozzles can reduce performance.
• Storage: Store the water jet in a clean, dry, and protected area. If storing for an extended period, follow the engine manufacturer's instructions for long-term storage, which typically includes fuel stabilization and draining.
