Question and answer
1) Why doesn't the machine work after pressing the switch?
There is a steering deflector rod on the upper part of the switch, which is locked. Turn it to the position where rotation is required, press
the knob again, and then the machine will start to rotate.
2) Why does the electric hand drill stop operating before the screw is tightened?
The machine has a low-voltage protection function. In case of insufficient power of the battery pack, the machine cannot work. Please
confirm the power of the battery pack.
This machine has a temperature protection function. When the machine works at full load for a long time, the battery pack can
overheat and the temperature protection system will start and cause the machine to stop operating. Please cool the machine to normal
temperature before continuing to use.
Please adjust the torque adjusting ring between the body and collet. The torque corresponding to position 1 is the minimum, and the torque
corresponding to position 20 is the maximum. The problem can be solved by adjusting the torque adjusting ring to a higher gear.
3) Why are working hours of the same battery pack different?
As mentioned above, if a battery pack has not been used for a long time, its working time shall be shortened, which is the problem of
charging times.
After charging and using for several times, this situation shall be improved. In heavy work, for example, screwing large screws into
hardwood, the power of the battery pack is fast consumed. Do not charge in the environment below 0°C or above 45°C; otherwise, the
performance of the battery pack will also be affected.
