Question and answer:
1）Why does the machine not operate after the switch is pressed?
The reversing yoke on the upper part of switch is locked. Turn it to the position where the rotation direction is in need, and then press
the button to rotate the machine.
2） Why is the service life of same kind of battery pack different?
As mentioned above, if a battery pack is left unused for a long time, its service life may be shortened. This is the matter of charging
frequency. Several times of charging and use may improve the situation. In case of heavy work, e.g. when the large bolt is tightened,
the battery pack will run out soon. Do not charge the machine at the temperature below 0° C or above 45° C. Otherwise, the
performance of battery pack will be affected.
Maintenance：
Be sure to pull off the plug before repairing or replacing the machine.
The electric tool does not require additional lubrication or other maintenance. Do not wash the electric tool with water or chemical
cleaner. Wipe it with a dry cloth. Tool shall be stored under the dry conditions and the vent of motor shall be kept clean. Try not to use it
in a dusty environment.
