Setup
1. Initial Charging
Before first use, fully charge the screwdriver. Connect the provided USB charging cable to the charging port located at the base of the handle. Plug the other end into a standard USB power adapter (not included) or a computer USB port. The charging indicator light will illuminate during charging and change color or turn off when fully charged. A full charge typically takes a few hours.
2. Installing Driver Bits
To install a driver bit, pull back the collar on the chuck of the screwdriver. Insert the desired 1/4-inch hex shank driver bit firmly into the chuck until it clicks into place. Release the collar to secure the bit. To remove a bit, pull back the collar and pull the bit out.
3. Attaching the Right-Angle Head (Optional)
For working in tight or awkward spaces, the included right-angle attachment can be used. Align the hex shaft of the right-angle head with the screwdriver's chuck and push it in until it locks. Insert your desired driver bit into the right-angle head as described above.
Operating Instructions
1. Power On/Off and Direction Control
The screwdriver features a slide switch for controlling direction and power. Push the switch forward for tightening (clockwise rotation) and backward for loosening (counter-clockwise rotation). The middle position is the neutral/lock position, which prevents accidental activation and conserves battery life. Always ensure the switch is in the neutral position when not in use or when changing bits.
2. Using the LED Light
The integrated LED light automatically illuminates when the screwdriver is in operation, providing visibility to your work area. Some models may feature a separate switch or a multi-position switch for the LED light, allowing for precise spot lighting or a broader floodlight effect. Refer to the specific markings on your device for detailed light control.
3. Applying Torque
The screwdriver delivers a maximum torque of 4 N.M, suitable for most light to medium fastening applications. Apply steady, even pressure when driving screws. Avoid excessive force, especially with smaller screws or delicate materials, to prevent stripping the screw head or damaging the workpiece.
Maintenance
- Charging: Recharge the battery regularly, even if the screwdriver is not used frequently, to maintain optimal battery health. Avoid completely draining the battery before recharging.
- Storage: Store the screwdriver and its accessories in a dry, cool place, away from direct sunlight and extreme temperatures. Keep the switch in the neutral position during storage.
- Cleaning: Wipe the tool with a clean, damp cloth to remove dust and debris. Do not use harsh chemicals or abrasive cleaners. Ensure the charging port is free of dust and moisture.
