4.2 Inserting Screwdriver Bits

The screwdriver uses standard 1/4-inch hex shank bits. Use the magnetic bit holder for extended reach or to secure bits more firmly.

2. Insert the hex end of the bit directly into the screwdriver's chuck until it clicks into place.
3. To use the magnetic bit holder, insert the bit into the holder first, then insert the holder into the screwdriver's chuck.
4. Ensure the bit is securely seated before operation.

5. Operating Instructions

5.1 Powering On/Off and Direction Control

The screwdriver is activated by pressing the trigger. The direction of rotation is controlled by the 2-side switch.

• For delicate tasks or when starting a screw, begin with light pressure and increase as needed.
• Avoid over-tightening screws, especially in soft materials, to prevent stripping the screw head or damaging the workpiece.
• Monitor the battery level; performance may decrease as the battery drains.
