Swivelling the auxiliary handle (see figure A)
You can swivel the auxiliary handle (17) to any angle for a
safe work posture that minimises fatigue.
– Loosen the wing bolt (16) of the auxiliary handle (17)
and adjust the auxiliary handle (17) to the required posi-
tion. Then retighten the wing bolt (16) of the auxiliary
handle (17).
Make sure that the clamping ring of the auxiliary handle
slots into the corresponding groove on the housing.
Selecting drill chucks and tools
Hammer drilling and chiselling require SDS-plus application
tools that are inserted into the SDS-plus drill chuck.
For drilling without impact in wood, metal, ceramic and
plastic as well as for screwdriving, tools without SDS‑plus
are used (e.g. cylindrical shank drill bits). For these tools, a
keyless chuck or a keyed chuck are required.
PBH 3000-2 FRE: The SDS plus quick-change chuck (2) can
easily be swapped with the keyless quick-change chuck (1)
supplied.

Changing the Tool

The dust protection cap (4) largely prevents the penetration
of drilling dust into the tool holder during operation. When
inserting the tool, make sure that the dust protection cap (4)
does not become damaged.
Replace a damaged dust protection cap immediately.
u
It is recommended that you have use an after-sales
service for this.
Changing the tool (SDS plus)
Inserting SDS plus application tools (see figure F)
The SDS-plus drill chuck enables you to change the applica-
tion tool easily and conveniently without needing to use ad-
ditional tools.
– PBH 3000-2 FRE: Insert the SDS plus quick-change
chuck (2).
– Clean and lightly grease the shank of the application tool.
– Insert the application tool into the tool holder while turn-
ing it until it locks automatically.
– Check that it is locked by pulling on the tool.
As a requirement of the system, the SDS-plus application
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 application tools (see figure G)
– Push the locking sleeve (5) back and remove the applica-
tion tool.
Changing the keyed chuck
PBH 2800 RE/PBH 2900 RE
Inserting the application tool

be used for hammer drilling or chiselling. Tools without SDS
plus and their drill chucks are damaged by hammer drilling
or chiselling.
– Insert a keyed chuck (21).
– Open the keyed chuck (21) by turning it until the tool can
be inserted. Insert the tool.
– Insert the chuck key into the corresponding holes of the
keyed chuck (21) and clamp the tool evenly.
– Turn the impact/mode selector switch (12) to the
"drilling" position.
Removing the application tool
