Head of Product
Certification
Insert the SDS-plus drilling tool to the stop into
the SDS-plus tool holder 1. 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.
Retighten the wing bolt for the depth stop ad-
justment 9 again.
The knurled surface of the depth stop 11 must
face upward.
Selecting the Tool Holder
For hammer drilling, SDS-plus drilling tools that
can be inserted into the SDS-plus tool holder 1
are required.
For drilling without impact in wood, metal, ce-
ramic and plastic as well as for screwdriving and
tapping, use non-SDS-plus drilling tools (e. g.,
drill bits with cylindrical shank). A keyless drill
chuck is required for such drilling tools.
Note: Do not use tools without SDS-plus for
hammer drilling or chiselling! Tools without
SDS-plus and their drill chucks are damaged by
hammer drilling or chiselling.
The SDS-plus tool holder 1 can easily be ex-
changed against the quick change keyless chuck
12.
Changing the Tool Holder
Dismounting the SDS-plus Tool Holder or the
Quick change keyless chuck (see figure B)
Turn the mode selector switch 7 temporarily to
the "drilling" position in order to lock the tool
holder.
Firmly turn the locking sleeve 3 in the direction
of the arrow and pull off the tool holder 1 or the
quick change keyless chuck 12 toward the front.
After removing, protect the tool holder 1 or the
quick change keyless chuck 12 against contami-
nation. Lightly lubricate the engaging grooves, if
required.
