8.Regulating the number of rotations and hammering (Fig. 4)
This Rotary Hammer is equipped with a built- in electronic control circuit that can adjust and regulate the number of rotations and times of hammering. This Rotary Hammer can be used by adjusting the dial, depending upon the contents of operation, such as boring holes into fragile materials, chipping, centering, etc.
The scale ‘1’ of the dial is designed for a minimum speed with the number of 240 rotations per minute and 1320 times of blow per minute. The scale ‘6’ is designed for a maximum speed with the number of 480 rotations per minute and 2650 times of blow per minute.
CAUTION:
