Safety Clutch
If the tool insert becomes caught or jammed,
the drive to the drill spindle is interrupted.
Because of the forces that occur, always hold
the power tool firmly with both hands and
provide for a secure stance.
If the power tool jams, switch the machine off
and loosen the tool insert. When switching
the machine on with the drilling tool jammed,
high reaction torques can occur.
Changing the Chiselling Position (Vario-Lock)
The chisel can be locked in 12 positions. In this man-
ner, the optimum working position can be set for each
application.
Insert the chisel into the tool holder.
Press and hold the unlocking button 3 and turn the
mode selector switch 4 to "Changing the chiselling
position (Vario-lock)".
Turn the tool holder to the desired chiselling position.
Press and hold the unlocking button 3 and turn the
mode selector switch 4 to the "Chiselling" position.
The tool holder is locked in this position.
The mode selector switch 4 must always be
locked in the "Chiselling" position when chis-
elling.
Maintenance and Service
Maintenance and Cleaning
Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep the
machine and ventilation slots clean.
A damaged dust protection cap should be
changed immediately. We recommend having
this carried out by an after-sales service.

Service Indicator 7
When the carbon brushes are worn out, the machine
switches itself off. This is indicated approx. 8 hours
beforehand by the lighting or blinking of the service
indicator 7. The machine must then be sent to an after-
sales service agent.
If the machine should fail despite the care taken in man-
ufacturing and testing procedures, repair should be
carried out by an after-sales service centre for BTI
power tools.
In all correspondence and spare parts orders, please
always include the 7-digit order number given on the
nameplate of the machine.
Disposal
The machine, accessories and packaging should be
sorted for environmental-friendly recycling.
Only for EC countries:
Do not dispose of power tools into
household waste!
According the European Guideline
2002/96/EC for Waste Electrical and
Electronic Equipment and its implemen-
tation into national right, power tools
that are no longer usable must be collected separately
and disposed of in an environmentally correct manner.
Subject to change without notice.
