5. Operating Instructions
Once assembled, your OIMG screwdriver is ready for use. The ratchet mechanism enhances efficiency and reduces strain.
5.1 Changing Bits
To change a bit, simply pull the current bit out of the magnetic interface. Select the new bit and push it firmly into the magnetic interface until it is securely seated.
5.2 Using the Ratchet Function
The main handle features a ratchet switch. This switch allows you to set the direction of rotation (clockwise, counter-clockwise) or lock the handle in a fixed position. Adjust the switch according to whether you are tightening or loosening a screw. The 6.2° ratchet design allows for small, precise turns without repositioning your hand.

6. Maintenance
Proper maintenance will extend the life and performance of your OIMG screwdriver set.
- Cleaning: After each use, wipe down the handle and bits with a clean, dry cloth to remove any dirt, grease, or debris. For stubborn grime, a slightly damp cloth can be used, followed by thorough drying.
- Storage: Always store the screwdriver set in its original protective case when not in use. This prevents loss of bits, protects them from damage, and keeps them organized. Store in a dry environment to prevent rust.
- Inspection: Periodically inspect the bits for wear or damage. Replace any worn or damaged bits to maintain precision and prevent stripping screws. Check the magnetic interface for any debris that might hinder bit retention.

7. Troubleshooting
If you encounter any issues with your screwdriver set, refer to the following common problems and solutions:
- Bit is not holding securely:
- Ensure the bit is fully inserted into the magnetic interface.
- Check the magnetic interface for any metal shavings or debris that might weaken the magnetic hold. Clean if necessary. - Ratchet mechanism feels stiff or is not engaging:
- Ensure the ratchet switch is fully engaged in one of the three positions (clockwise, counter-clockwise, or locked).
- Clean any visible debris around the ratchet switch. - Screws are stripping:
- Ensure you are using the correct size and type of bit for the screw head.
- Apply firm, consistent pressure while turning.
- Avoid excessive force, especially when using the ratchet function.
8. User Tips
- Organize Bits: Utilize the color-coded rings on the bits to quickly identify and select the correct type for your task. Always return bits to their designated slots in the case to maintain organization.
- Leverage the Ratchet: For repetitive tasks, the ratchet function can significantly speed up work and reduce wrist fatigue. Experiment with the T-shaped configuration for extra torque on stubborn fasteners.
- Magnetic Advantage: The magnetic tip not only holds bits securely but also helps to hold screws in place, preventing drops in tight spaces.
