Inserting the Quick Change Chuck
(see figure F)
– Before inserting, clean the quick change
chuck and apply a light coat of grease to the
shank end.
– Grasp the SDS-plus quick change chuck 2 or
the quick change keyless chuck 1 completely
with your hand. Slide the quick change chuck
with a turning motion onto the drill chuck
mounting 24 until a distinct latching noise is
heard.
– The quick change chuck is automatically
locked. Check the locking effect by pulling
the quick change chuck.
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 immediately. We recommend hav-
ing this carried out by an after-sales serv-
ice.
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 cer-
tain radial run-out at no-load, which has no ef-
fect 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.
