2. Safety Instructions
Always observe the following safety precautions to reduce the risk of injury or damage.
- Read the Manual: Familiarize yourself with all instructions and warnings before use.
- Personal Protective Equipment: Always wear appropriate eye protection, hearing protection, and other personal protective equipment as required by your work environment.
- Air Pressure: Ensure the air supply pressure does not exceed the maximum recommended pressure for the hose reel and connected tools.
- Secure Mounting: The hose reel must be securely mounted to a stable surface (wall or ceiling) using appropriate fasteners.
- Hose Inspection: Regularly inspect the hose for cuts, abrasions, bulges, or other damage. Replace damaged hoses immediately.
- Connection Integrity: Ensure all connections (hose to reel, hose to tool, air supply to reel) are tight and leak-free before operating.
- Retraction Safety: When retracting the hose, guide it manually to prevent uncontrolled whipping, which can cause injury or damage. Do not release the hose abruptly.
- Children and Bystanders: Keep children and bystanders away from the work area during operation.

4. Setup and Installation
Proper installation is crucial for the safe and effective operation of the hose reel.
4.1 Choosing a Mounting Location
Select a sturdy wall or ceiling location capable of supporting the weight of the hose reel and the forces exerted during hose extension and retraction. Ensure the location allows for full hose extension without obstruction and provides easy access to the air supply.
4.2 Mounting the Hose Reel
- Position the hose reel against the chosen mounting surface.
- Mark the locations for the mounting holes using the integrated brackets as a template.
- Drill appropriate pilot holes for your chosen fasteners (screws, bolts, anchors – not included).
- Securely attach the hose reel to the wall or ceiling using suitable hardware. Ensure all fasteners are tightened to prevent movement.

4.3 Connecting to Air Supply
Connect your compressed air supply line to the inlet fitting on the hose reel. Ensure a tight, leak-free connection. It is recommended to use thread sealant tape for optimal sealing.
5. Operating Instructions
5.1 Extending the Hose
Grasp the hose firmly and pull it out to the desired length. The automatic locking mechanism will engage at various intervals, holding the hose in place. You will hear a click as it locks.
5.2 Connecting Air Tools
The Metabo SA 312 is equipped with a 1/4 inch universal quick connection coupling. To connect an air tool, insert the tool's plug nipple into the coupling until it clicks securely into place.

5.3 Retracting the Hose
To retract the hose, pull it out slightly further until the locking mechanism disengages. Then, slowly guide the hose back into the reel. Do not release the hose abruptly, as this can cause it to whip and potentially cause injury or damage.
5.4 Disconnecting Air Tools
To disconnect an air tool, pull back the collar on the quick connection coupling and remove the tool's plug nipple. Ensure the air supply to the tool is off before disconnecting.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your Metabo SA 312 hose reel.
- Hose Inspection: Periodically inspect the entire length of the PU hose for any signs of wear, cuts, kinks, or damage. Replace the hose if any damage is found.
- Connection Checks: Ensure all air connections are tight and free of leaks. Apply thread sealant as needed.
- Cleaning: Keep the hose reel casing and hose clean from dirt, dust, and debris. Use a damp cloth for cleaning; avoid harsh chemicals.
- Mounting Security: Regularly check the mounting bolts or screws to ensure they remain tight and secure.
- Lubrication: The internal retraction mechanism is generally maintenance-free. Do not attempt to lubricate internal components unless specifically instructed by Metabo service personnel.
7. Troubleshooting
Refer to the following table for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Hose does not retract fully. | Hose is kinked or obstructed. Spring mechanism is weak or damaged. | Check for kinks or obstructions along the hose path. Ensure the hose is clean. If the spring is damaged, contact Metabo service. |
| Hose does not lock in place. | Locking mechanism is dirty or damaged. | Clean the locking mechanism area. If damaged, contact Metabo service. |
| Air leaks from connections. | Loose connections, worn seals, or damaged hose/fittings. | Tighten all connections. Inspect O-rings and seals; replace if worn. Check hose and fittings for damage. |
