3. Setup

3.1 Initial Charging

Before first use, fully charge the electric screwdriver. The magnetic case features an innovative contact charging system. Simply place the screwdriver into its designated slot within the charging dock. Connect the provided USB-C cable to the case and a suitable power source (e.g., USB wall adapter, computer USB port).

3.2 Attaching Bits

Select the appropriate S2 steel precision bit for your task. The bits are magnetically held in place within the screwdriver's chuck for quick and easy changes. Simply insert the desired bit firmly into the opening at the tip of the screwdriver.

3.3 Using the Anti-static Wrist Strap

For sensitive electronic components, use the anti-static wrist strap to prevent electrostatic discharge (ESD) damage. Attach the wrist strap to your wrist and clip the other end to a grounded metal object or the anti-static mat provided in some workstation setups.

4. Operating Instructions

4.1 Power On/Off and Direction Control

The electric screwdriver features a one-press switch-on button. Use the arrow buttons (up/down) to control the rotation direction (forward for tightening, reverse for loosening). The LED light will illuminate automatically when the screwdriver is in operation, providing shadow-free illumination.

4.2 Torque Settings

The screwdriver offers two torque settings for precision control:

• Low Torque (I): 0.05 N·m (±0.03 N·m) - Ideal for very delicate components.
• High Torque (II): 0.2 N·m (±0.08 N·m) - For slightly more resistant screws.

Select the appropriate torque level by rotating the collar at the base of the screwdriver. Always start with the lower torque setting and increase if necessary to avoid damaging components.

4.3 Using Auxiliary Tools

The kit includes various tools for specific tasks:

• Spudgers and Pry Knife: Use these non-marring tools to safely open electronic device casings without causing damage.
• Opening Picks: Thin plastic picks for separating tight seams and clips.
• Tweezers: For handling small components and wires with precision.
• Suction Cup: To assist in lifting screens or panels.

5. Maintenance

5.1 Cleaning

Wipe the screwdriver and bits with a dry, soft cloth after each use to remove dust and debris. Avoid using liquid cleaners or solvents, as these may damage the tool or its components.

5.2 Bit Storage and Organization

Always return bits to their designated slots in the magnetic storage case to prevent loss and maintain organization. The magnetic pad within the case can also be used to temporarily hold screws and small parts during repair.

5.3 Magnetizing/Demagnetizing Bits

The magnetic case includes dedicated zones for magnetizing and demagnetizing screwdriver bits. If a bit loses its magnetic strength, rub it against the "magnetize" zone. To demagnetize, rub it against the "demagnetize" zone.

6. Troubleshooting

• Screwdriver not turning on: Ensure the screwdriver is fully charged. If the issue persists, contact customer support.
• Bits slipping: Ensure the correct bit size and type are used for the screw. Verify the bit is fully inserted into the chuck. If the bit is worn, replace it.
• Screws not holding to bit: Use the magnetizing zone in the case to re-magnetize the bit.
• Difficulty opening device casing: Ensure you are using the correct spudger or pry tool for the specific device. Apply gentle, even pressure.
