The auxiliary handle 14 can be set to any position for a secure
and low-fatigue working posture.
– Turn the bottom part of the auxiliary handle 14 in counter-
clockwise direction and swivel the auxiliary handle 14 to
the desired position. Then retighten the bottom part of the
auxiliary handle 14 by turning in clockwise direction.

Selecting Drill Chucks and Tools
For hammer drilling and chiselling, SDS-plus tools are re-
quired that are inserted in the SDS-plus drill chuck.
For drilling without impact in wood, metal, ceramic and plas-
tic as well as for screwdriving, tools without SDS-plus are
used (e.g., drills with cylindrical shank). For these tools, a
keyless chuck or a key type drill chuck are required.
GBH 2-26 DFR: The SDS-plus quick change chuck 2 can easi-
ly be replaced against the quick change keyless chuck 1 pro-
vided.
Changing the Key Type Drill Chuck
(GBH 2-26 E/RE/DE/DRE)
To work with tools without SDS-plus (e.g., drills with cylindri-
cal shank), a suitable drill chuck must be mounted (key type
drill chuck or keyless chuck, accessories).
Mounting the Key Type Drill Chuck (see figure C)
– Screw the SDS-plus adapter shank 20 into a key type drill
chuck 19. Secure the key type drill chuck 19 with the se-
curing screw 18. Please observe that the securing
screw has a left-hand thread.
Inserting the Key Type Drill Chuck (see figure C)
– Clean the shank end of the adapter shank and apply a light
coat of grease.
– Insert the key type drill chuck with the adapter shank into
the tool holder with a turning motion until it automatically
locks.
– Check the locking effect by pulling the key type drill chuck.
Removing the Key Type Drill Chuck
– Push the locking sleeve 5 toward the rear and pull out the
key type drill chuck 19.
Removing/Inserting the Quick Change Chuck
(GBH 2-26 DFR)
Removing the Quick Change Chuck (see figure D)
– Pull the lock ring for the quick change chuck 6 toward the
rear, hold it in this position and pull off the SDS-plus quick
change chuck 2 or the quick change keyless chuck 1 to-
ward the front.
– After removing, protect the replacement chuck against
contamination.
Inserting the Quick Change Chuck (see figure E)
– Before inserting, clean the quick change chuck and apply a
light coat of grease to the shank end.
– Grasp the SDS-plus quick change chuck 2 or the quick
change keyless chuck 1 completely with your hand. Slide
the quick change chuck with a turning motion onto the drill
chuck mounting 21 until a distinct latching noise is heard.
– The quick change chuck is automatically locked. Check the
locking effect by pulling the quick change chuck.
