Soft Start Feature
The soft start feature allows the impact rate to build up
more slowly, thus preventing the chisel or point from
"bouncing" around on the masonry when starting up.
Active Vibration Control
The active vibration control neutralizes rebound vibration
from the hammer mechanism. Lowering hand and arm
vibration, it allows more comfortable use for longer periods
of time and extends the life of the unit.
Electronic Impact Energy Control Dial (Fig. A)

The electronic impact energy control dial
tool control for precise chiselling with minimal break‑out
when chiselling soft or brittle materials. It also allows the use
of smaller accessories without risk of breakage.
