2. T-Handle Mode: For increased leverage, detach one of the handle ends and insert it perpendicularly into the central opening of the main handle. Insert the desired bit into the magnetic tip.
3. Short Handle Mode: For tight spaces, use only one of the main handle pieces with a bit inserted directly.

5. Operating Instructions

To operate the AtuMan Ratchet Screwdriver Set:

1. Select Bit: Choose the appropriate bit for your screw type from the 24 included bits.
2. Insert Bit: Firmly insert the selected bit into the magnetic tip of the handle. The magnetic connection ensures the bit stays securely in place.
3. Configure Handle: Assemble the handle into your desired configuration (straight, T-handle, or short) based on the task and available space.
4. Set Ratchet Direction: Use the small switch on the central ratcheting mechanism to select the desired direction (clockwise for tightening, counter-clockwise for loosening).
5. Apply Torque: Place the bit onto the screw head and apply pressure while rotating the handle. The ratcheting mechanism will allow you to turn the screw without repositioning your hand.

7. Care & Maintenance

To ensure the longevity and optimal performance of your AtuMan Ratchet Screwdriver Set:

• Cleaning: Wipe down the handle and bits with a clean, dry cloth after each use to remove dirt, grease, or debris.

8. Troubleshooting

If you encounter issues with your screwdriver set, consider the following:

• Ratcheting Issue: Verify the direction switch is fully engaged in either the clockwise or counter-clockwise position. Ensure no debris is obstructing the mechanism.
• Handle Connection Loose: Ensure all detachable handle pieces are firmly pushed together until they click or are securely seated.
