Setup

1. Charging the Screwdriver

Before first use, fully charge the screwdriver. Connect the provided Type-C USB charging cable to the charging port located at the base of the screwdriver and to a compatible USB power source (e.g., wall adapter, computer USB port). The LCD screen will display the battery percentage and a lightning bolt icon, indicating it is charging. The lightning bolt icon will stop flashing when fully charged.

2. Installing/Changing Bits

The screwdriver features a magnetic bit holder for easy and secure bit changes.

  1. Select the appropriate S2 metal bit for your task.
  2. Simply push the bit firmly into the magnetic bit holder at the front of the screwdriver until it clicks into place.
  3. To remove, pull the bit straight out.

3. Using the Extension Bar and Slim Shaft Bits

For screws in recessed or hard-to-reach areas, attach the 2.6" magnetic extension bit holder first, then insert the desired bit into the extension. The 2.0" slim shaft bits are designed for very tight spaces.

Operating Instructions

Troubleshooting
