DO NOT use under wet conditions or in presence of
flammable liquids or gases.
These rotary 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.
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.
Electronic Speed and Impact
Control (fi g. 2)
The electronic speed and impact control (b) 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
Service Indicator LED (fi g. 2)
The red service indicator LED (c) lights up when the
carbon brushes are nearly worn out to indicate that
the tool needs servicing. After a further 8 hours of
use the motor will automatically be shut off.
The carbon brushes are not user-serviceable.
