INTENDED USE
Your rotary hammer has been designed for
professional hammerdrilling and light chipping,
chiselling and demolition applications.
DO NOT use under wet conditions or in presence of
flammable liquids or gases.
These hammers are professional power tools.
DO NOT let children come into contact with the
tool. Supervision is required when inexperienced
operators use this tool.
Soft Start Feature
The soft start feature allows to build up speed
slowly, thus preventing the drill bit from walking off
the intended hole position when starting. The soft
start feature also reduces the immediate torque
reaction transmitted to the gearing and the operator
if the hammer is started with the drill bit in an
existing hole.
Electronic Speed and Impact Control
(fi g. 2)
The electronic speed and impact control (c) offers
the following advantages:
– use of smaller accessories without risk of
breakage;
– minimised break-out when chiselling or drilling in
soft or brittle materials;
– optimal tool control for precise chiselling.
Torque Limiting Clutch
The torque limiting clutch reduces the maximum
torque reaction transmitted to the operator in case of
jamming of a drill bit. This feature also prevents the
gearing and electric motor from stalling. The torque
limiting clutch has been factory-set and cannot be
adjusted.
Complete Torque Control
D25701, D25730
The clutch torque can be switched between high
and low depending on the application. In normal
operation, the clutch is set in low torque which
has adequate torque for the majority of drilling
applications. If the bit jams in low torque, the clutch
activates much quicker than conventional hammer
clutches. Where low torque is not enough, the tool
can be switched into high torque providing a torque
setting similar to conventional machines. Every time
the tool is plugged in, the clutch will automatically
reset to low torque.
