Adjusting the Drilling Depth (see figure B)
The required drilling depth X can be set with the
depth stop 18.
– Press the button for the depth stop adjust-
ment 15 and insert the depth stop into the
auxiliary handle 17.
The knurled surface of the depth stop 18
must face downward.
– Insert the SDS-plus drilling tool to the stop

the movability of the SDS-plus drilling tool
can lead to incorrect adjustment of the drill-
ing 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 drill-
ing 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,
tools without SDS-plus are used (e.g., drills
with cylindrical shank). For these tools, a key-
less chuck or a key type drill chuck are required.
PBH 3000-2 FRE: The SDS-plus quick change
chuck 2 can easily be replaced against the quick
change keyless chuck 1 provided.
Replacing the Drill Chuck
(PBH 2800 RE/ PBH 2900 FRE/
PBH 3000 FRE Set)
To work with drilling tools without SDS-plus
(e. g., drill bits with cylindrical shank), the key
type drill chuck or the keyless chuck must be
mounted.
Mounting the Key Type Drill Chuck
(Accessory) (PBH 2800 RE) (see figure C)
– Screw the SDS-plus adapter shank 22 into a
key type drill chuck 21. Secure the key type
drill chuck 21 with the securing screw 20.
Please observe that the securing screw has
a left-hand thread.
