Overloading Operation: If the operator discovered the handle overheating or the revolutions plunging
rapidly while fastening, it means that the screwdriver is overloaded. Please change to a torque
screwdriver with higher power or reduce the frequency of fastening to prolong the lifespan of the
screwdriver.

If the screwdriver has operated for a long period, or if excessive current surges are experienced, the
screwdriver may overheat. In this case it will switch off automatically. When the heat has dispersed,
normal operation can be resumed.
