Product Components

- Ergonomic Handle: Designed for comfortable grip and maximum torque transfer.
- Ratchet Mechanism Selector: Allows selection of forward, reverse, or locked positions.
- Speed Drive Collar: Engages the speed drive function for rapid fastening/unfastening.
- Bit Holder: Securely holds standard 1/4-inch hex bits.
- Bit Storage Compartment: Located within the handle for convenient bit access.
Setup
Inserting and Changing Bits
- Select the appropriate 1/4-inch hex bit for your application.
- Insert the bit firmly into the bit holder at the tip of the screwdriver until it clicks into place.
- To remove a bit, pull it straight out from the bit holder.

Operating Instructions
Ratchet Mechanism
The ratchet mechanism allows for continuous turning in one direction without repositioning your hand. The selector ring, located near the bit holder, has three positions:
- "R" (Right/Clockwise): For fastening screws. The screwdriver will turn the bit clockwise when you twist the handle, and freewheel counter-clockwise.
- "L" (Left/Counter-clockwise): For unfastening screws. The screwdriver will turn the bit counter-clockwise when you twist the handle, and freewheel clockwise.
- Center (Locked): For fixed operation, acting as a traditional screwdriver without the ratchet function.

Speed Drive Function
The Speed Drive feature allows for rapid rotation of the bit, significantly increasing fastening or unfastening speed. To engage the Speed Drive:
- Ensure the ratchet mechanism is set to either "R" or "L" depending on your desired direction.
- Grip the main handle firmly with one hand.
- With your other hand, rotate the knurled Speed Drive collar (the part labeled "SPEED DRIVE") while maintaining pressure on the screw. This action will cause the bit to rotate at an accelerated rate.
- Release the collar to disengage the Speed Drive and return to standard ratcheting operation.

Maintenance
- Cleaning: Wipe the screwdriver clean with a dry or slightly damp cloth after each use. Do not use harsh chemicals or abrasive cleaners.
- Lubrication: The internal mechanism is factory-lubricated and generally does not require additional lubrication under normal use. If the ratchet action becomes stiff, a small amount of light machine oil can be applied to the moving parts, but avoid over-lubrication.
- Storage: Store the screwdriver and bits in a dry environment to prevent corrosion. Keep bits organized to prevent loss.
