6. Troubleshooting
If the screwdriver does not work properly, check the list below. If you cannot solve the problem do not open
the unit. Contact our customer service as soon as possible.
If the screwdriver does not run
- Check the outputting power.
- Check whether the plug is inserted properly and the outlet has power.
- Check for open or short circuit in AC wire. If an open or short circuit is found, replace the AC wire.
- Check if the carbon brush is damaged or worn out.
Inspect method: open the carbon brush cover and use an insulated rod to gently press the brush. If the
screwdriver resumes rotating, the carbon brush has reached the end of its service life and must be replaced
immediately.
If the screwdriver is not rotating normally
- Long-term usage causes the motor’s commutator to wear down. In this case, it must be replaced. (Please
contact our customer service)
If the bit falls out easily or wobbles
- Check that the bit matches our specifications. If not, change the bit to one that does.
- Check that the bit is inserted tightly into two guide channels within the bit shaft. If not, remove the bit and
re-insert it tightly.
- If the bit tends to wobble, remove the bit, rotate it 60 or 180 degrees and re-insert it.
7. After Use
- Storage and maintenance: when the unit is to be stored for a long period, remove the power supply and bit,
open the carbon brush cover and blow out any accumulated carbon brush dust with compressed air, and
wipe the exterior clean. Store the screwdriver carefully in a dry, dust-free place away from direct sunlight.
Store the bit in grease. To ensure continued serviceability, periodically check and maintain the screwdriver.
