Active Vibration Control
D25901, D25941
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
D25901 ONLY (FIG. 1)
The electronic impact energy control dial (C) offers optimal 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.
