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:
Do not adjust the dial during operation. Doing so can result in injury because the
Rotary Hammer must be held by only one hand, disabling the steady control of the
Rotary Hammer.
