Overload Clutch
 If the tool insert becomes caught or jammed,
the drive to the drill spindle is interrupted. Be-
cause 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.

Working Advice

 Before any work on the machine itself, pull the
mains plug.
Changing the Chiselling Position (Vario-Lock)
The chisel can be locked in 36 positions. In this
manner, the optimum working position can be set
for each application.
– Insert the chisel into the tool holder.
– Turn the mode selector switch 11 to the "Vario-
Lock" position (see "", page).
– Turn the tool holder to the desired chiselling po-
sition.
– Turn the mode selector switch 11 to the "chisel-
ling" position. The tool holder is now locked.
– For chiselling, set the rotation direction to right
rotation.
Inserting Screwdriver Bits (see figure J)
 Apply the power tool to the screw/nut only
when it is switched off. Rotating tool inserts can
slip off.
To work with screwdriver bits, a universal bit holder
22 with SDS-plus shank (accessory) is required.
– Clean the shank end of the adapter shank and
apply a light coat of grease.
– Insert the universal bit holder with a turning mo-
tion into the tool holder until it automatically
locks.
– Check the locking effect by pulling the universal
bit holder.
– Insert a screwdriver bit into the universal bit hold-
er. Use only screwdriver bits that match the
screw head.
– To remove the universal bit holder, pull the lock-
ing sleeve 5 toward the rear and remove the uni-
versal bit holder 22 out of the tool holder.

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.
– Clean the tool holder 3 each time after using.
If the replacement of the supply cord is necessary,
this has to be done by BTI or an authorized BTI ser-
vice agent in order to avoid a safety hazard.
In all correspondence and spare parts orders,
please always include the 7-digit order number giv-
en on the nameplate of the machine.

be sorted for environmental-friendly recycling.
