Overload 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 power tool on with the drilling tool
jammed, high reaction torques can occur.

Working Instructions

Changing the Chiselling Position (Vario-Lock)
(GBH 2-26 DE/DRE/DFR)
The chisel can be locked in 36 positions. In this man-
ner, 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 "Setting the Operating Mode", page 11).
Turn the tool holder to the desired chiselling position.
Turn the mode selector switch 11 to the chiseling posi-
tion. The tool holder is now locked.
For chiseling, set the rotation direction to right rotation.
Inserting Screwdriver Bits (see figure L)
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 27
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 motion 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 holder. Use
only screwdriver bits that match the screw head.
To remove the universal bit holder, pull the locking
sleeve 5 toward the rear and remove the universal bit
holder 27 out of the tool holder.

Maintenance and Service

Maintenance and Cleaning

Before any work on the power tool itself, pull
the mains plug.
For safe and proper working, always keep the
power tool and the 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 power tool should fail despite the care taken in
manufacturing and testing procedures, repair should
be carried out by an after-sales service center for
Bosch power tools.
In all correspondence and spare parts orders, please
always include the 10-digit article number given on the
type plate of the power tool.
