Setup
1. Inserting and Changing Bits
- To access stored bits, gently pull the end cap of the handle. The handle can store up to 6 double-ended bits.
- Select the appropriate double-ended bit for your task.
- Insert one end of the chosen bit into the extended locking bit holder until it clicks securely into place. Ensure the bit is fully seated to prevent slippage during use.
- To remove a bit, pull it firmly from the bit holder.
2. Adjusting the Ratcheting Mechanism
The screwdriver features a three-position selector ring located near the bit holder:
- F (Forward): For driving screws. The bit will turn clockwise when the handle is rotated clockwise, and ratchet freely counter-clockwise.
- R (Reverse): For removing screws. The bit will turn counter-clockwise when the handle is rotated counter-clockwise, and ratchet freely clockwise.
- L (Locked): For fixed operation, similar to a standard screwdriver. The bit will not ratchet in either direction.
Rotate the selector ring to the desired position (F, R, or L) before beginning your task.
Operating Instructions
1. Using SpeedDrive Technology
The SpeedDrive feature allows for rapid screw driving or removal. To engage SpeedDrive:
- Set the ratcheting mechanism to either F (Forward) for driving or R (Reverse) for removing.
- Place the bit into the screw head.
- With one hand, firmly grip the black knurled collar located just below the ratcheting selector.
- With your other hand, rotate the main handle back and forth. The SpeedDrive mechanism will ensure the bit continues to turn in the selected direction (clockwise for F, counter-clockwise for R) with each rotation of the handle, regardless of the direction of your hand movement on the handle. This eliminates the need to reposition your grip.

2. Driving and Removing Screws
- Select the correct bit and insert it into the bit holder.
- Set the ratcheting mechanism to F (Forward) for driving screws or R (Reverse) for removing screws. For tasks requiring maximum torque or precise control, set it to L (Locked).
- Place the bit firmly into the screw head, ensuring a snug fit to prevent cam-out.
- Apply downward pressure and rotate the handle in the appropriate direction. For SpeedDrive operation, follow the instructions above.
- Continue until the screw is fully driven or removed.

Maintenance
- Cleaning: Wipe the screwdriver and bits with a clean, dry cloth after each use to remove dirt, grease, and debris. Do not use harsh chemicals or abrasive cleaners.
- Lubrication: The internal ratcheting mechanism is factory-lubricated and generally does not require additional lubrication under normal use. If the mechanism feels stiff, a small amount of light machine oil can be applied sparingly to the moving parts.
- Storage: Store the screwdriver and bits in a dry environment to prevent rust. The in-handle bit storage helps keep bits organized and protected.
- Inspection: Regularly inspect bits for wear or damage. Replace worn or damaged bits to ensure optimal performance and prevent damage to screw heads.
