– Pull out the depth stop until the distance between 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 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.
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 2900RE/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/PBH 2900 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 se-
curing screw 20. Please observe that the securing
screw has a left-hand thread.
Inserting the Key Type Drill Chuck or the Keyless Chuck
(see figure D)
– Clean the shank end of the adapter shank and apply a light
coat of grease.
– Insert the key type drill chuck 21 or the keyless chuck 23
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
or the keyless chuck.
Removing the Key Type Drill Chuck or the Keyless Chuck

key type drill chuck 21 or the keyless chuck 23.
Removing/Inserting the Quick Change Chuck
(PBH 3000-2 FRE)

Changing the Tool

The dust protection cap 4 largely prevents the entry of drilling
dust into the tool holder during operation. When inserting the
tool, take care that the dust protection cap 4 is not damaged.
 A damaged dust protection cap should be changed im-
mediately. We recommend having this carried out by
an after-sales service.
Inserting SDS-plus Drilling Tools (see figure G)
The SDS-plus drill chuck allows for simple and convenient
changing of drilling tools without the use of additional tools.
– PBH 3000-2 FRE: Insert the SDS-plus quick change chuck 2.
– Clean and lightly grease the shank end of the tool.
– Insert the tool in a twisting manner into the tool holder until
it latches itself.
– Check the latching by pulling the tool.
As a requirement of the system, the SDS-plus drilling tool can
move freely. This causes a certain radial run-out at no-load,
which has no effect on the accuracy of the drill hole, as the
drill bit centres itself upon drilling.
Removing SDS-plus Drilling Tools (see figure H)
– Push back the locking sleeve 5 and remove the tool.
Inserting Drilling Tools without SDS-plus into the Key
Type Drill Chuck (PBH 2800 RE/PBH 2900 RE)

damaged by hammer drilling or chiselling.
