Operating Instructions
Using the Ring Magnet
The Wera 887/4 R features a strong ring magnet that holds screws firmly to the bit, preventing them from falling off during positioning and driving. This allows for one-handed operation and improved precision.

Maintenance
- Cleaning: Regularly wipe the bit holder with a clean, dry cloth to remove dust, dirt, and metal shavings. Avoid using harsh chemicals or abrasive materials.
- Lubrication: The internal mechanism is designed for maintenance-free operation. Do not attempt to lubricate or disassemble the unit, as this may affect its performance and void any warranty.
- Storage: Store the bit holder in a dry environment, away from excessive moisture and extreme temperatures, to prevent corrosion and maintain magnetic strength.
Troubleshooting
- Bit not locking securely: Ensure the bit is fully inserted until it clicks. Check for any debris obstructing the locking mechanism.
- Difficulty removing bit: Ensure the collar is pushed fully forward. If the bit is stuck, gently twist it while pushing the collar.
- Screws not holding to magnet: Verify that the screws are made of a ferromagnetic material. Clean any metal shavings or dirt from the ring magnet.
