- Screwdriver (Phillips head recommended for Euro screws)

- Prepare the Door: Drill a 35mm diameter cup hole into the cabinet door at the specified distance from the edge. The hinge is designed for a 48/6 drilling pattern. Refer to Figure 5 for typical dimensions.
- Attach Hinge to Door: Insert the hinge cup into the drilled hole on the door. Secure the hinge to the door using the provided screws.

4. Operating Instructions
Once installed and adjusted, the Häfele Metalla SM hinges operate automatically. The 110° opening angle allows for ample access to cabinet contents.
- Opening: Gently pull the cabinet door open. The hinge will allow the door to swing open up to 110 degrees.
- Closing: Push the cabinet door towards the closed position. The integrated soft-close mechanism will engage, slowly and quietly pulling the door shut, preventing slamming.
5. Maintenance
The Häfele Metalla SM hinges are designed for durability and require minimal maintenance. Regular care will ensure their longevity and smooth operation.
- Cleaning: Wipe the hinges periodically with a soft, dry cloth to remove dust and grime. Avoid abrasive cleaners or harsh chemicals, as these can damage the nickel-plated finish.
- Lubrication: Under normal use, the hinges do not require lubrication. If you notice any squeaking or stiffness after extended use, a small amount of silicone-based lubricant can be applied to the pivot points.
- Inspection: Periodically check all screws for tightness. Loose screws can affect hinge performance and door alignment. Tighten any loose screws gently to avoid stripping.
