5. Operating Instructions
5.1 Adjusting the Handle
The red handle can be adjusted to optimize grip and leverage for various applications:
- Loosen the red handle by unscrewing it a few turns.
- To pivot the handle: Tilt the handle towards the chuck end (past 90 degrees) to unlock the rotating collar.
- Rotate the handle/collar assembly around the body of the attachment to the desired position (there are 12 detents for precise positioning).
- Tilt the handle back to lock the collar in place.
- Tighten the red handle securely.
5.2 General Operation
- Always select the appropriate accessory for the task (e.g., drill bit for drilling, screwdriver bit for driving).
- Ensure the drill is set to a suitable speed and torque setting for the material and accessory being used. The attachment has a maximum RPM of 1750.
- When drilling, apply steady, even pressure. Avoid excessive force, which can cause the bit to bind or the tool to kick back.
- For driving screws, ensure the bit is fully engaged with the screw head to prevent stripping.
- The compact design allows access to spaces as narrow as 2 inches.

- Storage: Store the attachment in a dry, clean place, away from extreme temperatures and moisture.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Accessory (bit) does not stay in chuck. | Chuck collar not fully released or bit not fully inserted. | Ensure the chuck collar is pulled forward, insert the 1/4-inch hex bit completely, then release the collar. Pull on the bit to confirm it is secure. Only use 1/4-inch hex quick-release shank bits. |
| Attachment feels stiff or makes unusual noise. | Lack of lubrication or internal wear/damage. | Apply light oil or lithium grease to the lubrication port. If the issue persists, discontinue use and have the unit inspected by a qualified technician. |
| Reduced performance or excessive heat. | Exceeding torque/RPM limits, or internal damage. | Ensure you are not exceeding the maximum torque (235 in.-lbs.) or RPM (1750). Check for binding. If the problem continues, professional inspection is recommended. |
