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
All Rotary Hammers are equipped with a torque
limiting clutch that 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 (fig. B)
The electronic speed and impact control (2)
offers the following advantages:
- use of smaller drill bits without risk of bit breakage
- drilling into light and brittle materials without
shattering
- optimal tool control for precise chiselling
Service and power-ON indicator LEDs
(fig. B)
The red service indicator LED (3) lights up when
the carbon brushes are nearly worn out to
indicate that the tool needs servicing. After
approx. 8 hours of use the motor will
automatically be shut off.
The carbon brushes are not user-serviceable.
Take the tool to an authorized BTI repair agent.
Electrical safety
The electric motor has been designed for one
voltage only. Always check that the power supply
corresponds to the voltage on the rating plate.
Your BTI tool is double insulated in
accordance with EN 50144; therefore no
earth wire is required.
