Certification
The knurled surface of the depth stop 13 must
face downward.
Insert the SDS-plus drilling tool to the stop into
the SDS-plus tool holder 3. Otherwise, the mov-
ability of the SDS-plus drilling tool can lead to
incorrect adjustment of the drilling depth.
Pull out the depth stop until the distance be-
tween the tip of the drill bit and the tip of the
depth stop correspond with the desired drilling
depth X.
Selecting Drill Chucks and Tools
For hammer drilling and chiselling, SDS-plus
tools are required that are inserted in the SDS-
plus drill chuck.
For drilling without impact in wood, metal, ce-
ramic and plastic as well as for screwdriving and
thread cutting, 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 easily be replaced against the quick
change keyless chuck 1 provided.
Changing the Key Type Drill Chuck
(GBH 2-26 E/RE/DE/DRE)
To work with tools without SDS-plus (e.g., drills
with cylindrical shank), a suitable drill chuck
must be mounted (key type drill chuck or key-
less chuck, accessories).
Mounting the Key Type Drill Chuck
(see figure C)
Screw the SDS-plus adapter shank 19 into a key
type drill chuck 18. Secure the key type drill
chuck 18 with the securing screw 17. 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.
