Safety Instructions
WARNING: Always read and understand all safety warnings and instructions provided with your high-pressure cleaner before using this accessory. Failure to follow these instructions may result in electric shock, fire, and/or serious injury.
- Ensure the pipe unblocking set is correctly assembled and securely connected to the high-pressure cleaner before operation.
- Never direct the water jet at people, animals, or electrical equipment.
- Wear appropriate personal protective equipment, including eye protection and gloves.
- Do not use the set if the hose or any part is damaged.
- Always turn off the high-pressure cleaner and release residual pressure before disconnecting the hose or performing any maintenance.
- This product is designed for cold water use up to 60 °C. Do not exceed this temperature.
- Keep children and bystanders away during operation.
Setup
- Compatibility Check: Ensure your high-pressure cleaner is compatible. This set is suitable for Parkside high-pressure cleaners in the PHD 110, PHD 135, PHD 150, and PHD 170 series. An adapter is included for other common high-pressure cleaners (max. 115 bar working/nominal pressure), such as Kärcher models.
- Connect the Hose: Attach the pipe unblocking hose to the high-pressure cleaner's spray gun or outlet. Ensure a secure, leak-free connection. If using the adapter, connect the adapter first, then the hose to the adapter.
- Prepare the Drain: Clear any visible debris from the drain opening.

Operating Instructions
- Insert the Hose: Carefully feed the injection head of the hose into the pipe or drain opening. The continuous marking and marking ring on the hose indicate its progression into the pipe.
- Activate Pressure: Once the injection head is sufficiently inside the pipe, turn on the high-pressure cleaner. The rearward-facing pressure from the injector head will automatically propel the hose further into the pipe, clearing blockages as it advances.
- Advance and Retreat: Guide the hose slowly into the pipe. If resistance is met, gently move the hose back and forth to help dislodge the blockage. Do not force the hose.
- Monitor Progress: Use the markings on the hose to track how far it has entered the pipe.
- Completion: Once the blockage is cleared and water flows freely, turn off the high-pressure cleaner and release any residual pressure before slowly pulling the hose out of the pipe.

Maintenance and Storage
- Cleaning: After each use, thoroughly rinse the hose and injection head with clean water to remove any debris or residue.
- Inspection: Regularly inspect the hose, connections, and injection head for any signs of wear, damage, or blockages. Do not use if damaged.
- Storage: Coil the hose neatly and store it in a dry, frost-free location, away from direct sunlight and extreme temperatures. Ensure it is protected from kinks or sharp bends.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Hose does not advance into the pipe. | Severe blockage; insufficient water pressure; kink in the hose. | Ensure high-pressure cleaner is operating at full power. Gently move the hose back and forth. If blockage persists, consider alternative methods or professional help. Check for kinks in the hose. |
| Water leaks from connections. | Loose connection; damaged O-ring or seal. | Tighten all connections. Inspect and replace any damaged O-rings or seals. |
| No water coming from the injection head. | No water supply to the pressure washer; pressure washer not turned on; nozzle blocked. | Check water supply and pressure washer operation. Turn off the unit, release pressure, and inspect the injection head for blockages. |
