Assembly
Before any work on the power tool itself, pull
the mains plug.
Auxiliary Handle
Operate your power tool only with the auxil-
iary handle 14.
Rotating the Auxiliary Handle (see figure A)
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 coun-
terclockwise 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.
Pay attention that the clamping band of the auxiliary
handle is positioned in the groove on the housing as
intended for.
Adjusting the Drilling Depth (see figure B)
The required drilling depth X can be set with the depth
stop 13.
Press the button for the depth stop adjustment 12 and
insert the depth stop into the auxiliary handle 14.
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 movability of the
SDS-plus drilling tool can lead to incorrect adjustment
of the drilling depth.
Pull out the depth stop until the distance between the
tip of the drill bit and the tip of the depth stop corre-
spond with the desired drilling depth X.
Selecting Drill Chucks and Tools
For hammer drilling and chiseling, SDS-plus tools are
required that are inserted in the SDS-plus drill chuck.
For drilling without impact in wood, metal, ceramic and
plastic as well as for screwdriving and thread cutting,
tools without SDS-plus are used (e.g., drills with cylin-
drical shank). For these tools, a keyless chuck or a key
type drill chuck are required.
Note: Do not use tools without SDS-plus for hammer
drilling or chiseling! Tools without SDS-plus and their
drill chucks are damaged by hammer drilling or chiseling.
GBH 2-26 DFR: The SDS-plus quick change chuck 2
can easily be replaced against the quick change key-
less chuck 1 provided.

sories).
Mounting the Key Type Drill Chuck
