4. Setup and Bit Installation
The ANEX No. 3614 screwdriver handle is designed for quick and secure bit changes. Ensure the bit is fully inserted for stable operation.
- Selecting a Bit: Choose the appropriate bit size (+00, +0, +1, or +2) for your task. The bits are color-coded for quick identification.
- Inserting a Bit: Firmly push the hex end of the desired bit into the handle's receiver. Ensure it clicks into place or is securely seated.
- Removing a Bit: Pull the bit straight out from the handle. Some resistance is normal to ensure a secure fit during use.

5. Operation
This precision screwdriver is intended for manual fastening and unfastening of small screws. Always match the bit size to the screw head to prevent damage to both the screw and the bit.
- Bit Selection: Use the correct bit size for the screw. The included bits are JIS (Japanese Industrial Standard) cross-head types.
- Application: Place the tip of the screwdriver bit into the screw head. Apply firm, steady pressure while turning the handle clockwise to tighten or counter-clockwise to loosen.
- Precision Use: For delicate electronics or small components, apply minimal force to avoid stripping screw heads or damaging the workpiece.

6. Maintenance
Proper maintenance ensures the longevity and performance of your ANEX screwdriver set.
- Cleaning: Wipe the handle and bits with a clean, dry cloth after each use to remove dirt, grease, or debris.
- Storage: Store the screwdriver set in a dry environment, away from moisture and corrosive materials. Keep bits organized to prevent loss.
- Inspection: Periodically inspect bits for wear or damage. Worn bits can strip screw heads. Replace damaged bits as needed.
7. Troubleshooting
If you encounter issues while using your ANEX precision screwdriver, consider the following:
- Screw Head Stripping: Ensure you are using the correct bit size for the screw. Apply adequate downward pressure to prevent the bit from camming out.
- Bit Not Holding Securely: Verify that the bit is fully inserted into the handle. If the bit still feels loose, inspect the handle's receiver and the bit's hex shank for damage.
- Difficulty Loosening a Screw: For very tight screws, ensure maximum contact between the bit and the screw head. Avoid excessive force that could damage the tool or fastener.
