Working Advice
Changing the Chiselling Position (Vario-Lock)
(GBH 2-26 DE/DRE/DFR)
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 "Setting the Operating
Mode", page 24).
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 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 29 with SDS-plus shank (accessory) is re-
quired.
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 lock-
ing sleeve 5 toward the rear and remove the uni-
versal bit holder 29 out of the tool holder.
