INTENDED USE

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.

DO NOT use under wet conditions or in presence of flammable

liquids or gases.

These demolition hammers are professional power tools. DO NOT let

children come into contact with the tool. Supervision is required when

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.

disconnect tool from power source before installing and
