electronic control circuit that can adjust and regulate
the num ber of rotations and tim es of ham m ering.
This Rotary Ham m er can be used by adjusting the
dial, depending upon the contents of operation,
such as boring holes into fragile m aterials, chipping,
centering, etc.
The scale '1' of the dial is designed for a m inim um
speed w ith the num ber of 240 rotations per m inute
and 1320 tim es of blow per m inute. The scale '6'
is designed for a m axim um speed w ith the num ber
of 480 rotations per m inute and 2650 tim es of blow
per m inute.
CAUTION:
Do not adjust the dial during operation. Doing so
can result in injury because the Rotary Ham m er
