The D25901 and D25941 heavy-duty demolition hammers are
designed for professional demolition, chipping and chasing
applications in concrete, brick, stone and other masonry materials.

inexperienced operators use this tool.
Residual Risks
• In spite of the application of the relevant safety regulations and the
implementation of safety devices, certain residual risks cannot be
avoided.
These are:
– Impairment of hearing.
– Risk of dust inhalation.
– Risk of personal injury due to prolonged use.
– Risk of burns due to accessories becoming hot during
operation.
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
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.
