Replacing the Drill Chuck
f Do not carry the power tool by the quick
change chuck.
To work with drilling tools without SDS-plus, a
keyless quick change chuck must be mounted.
Removing the Quick Change Chuck
(see figure C)
–
Grasp the lock ring of the quick change
chuck
8 and pull it firmly in the direction of
the arrow. The quick change chuck is re-
leased and can be removed toward the front.
Inserting the Quick Change Chuck
(see figure D)
–
Grasp the SDS-plus quick change chuck 4 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
20 until a distinct latching noise is
heard.
–
Check the latching by pulling the tool.
Changing the Tool
The dust protection cap 6 largely prevents the
entry of drilling dust into the tool holder during
operation. When inserting the tool, take care
that the dust protection cap
6 is not damaged.
f
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 E)
The SDS-plus drill chuck allows for simple and
convenient changing of drilling tools without the
use of additional tools.
–
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 F)
–
Push back the locking sleeve 7 and remove
the tool.
Inserting Screwdriver Bits in a SDS-plus Quick
Change Chuck (see figure G)
To insert screwdriver bits, the SDS-plus adapter
21 must be used.
PBH 220 RE:
Inserting Drilling Tools without SDS-plus
(see figures H–I)
To work with tools without SDS-plus (e.g., drills
with cylindrical shank), a suitable drill chuck
must be mounted (key type drill chuck or key-
less chuck, accessories).
–
Screw the SDS-plus adapter shank 24 into a
key type drill chuck 23 . Secure the key type
drill chuck 23 with the securing screw 22 .
Please observe that the securing screw has
a left-hand thread.
–
Slide the quick change chuck with a turning
motion onto the drill chuck mounting
20 until
a distinct latching noise is heard.
–
Check the latching by pulling the tool.
PBH 240 RE:
Inserting Drilling Tools without SDS-plus
(see figure K)
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.
–
Insert a quick change chuck. (see Inserting
the Quick Change Chuck, page 22)
–
Hold the retaining ring 3 of the quick change
keyless chuck. Open the tool holder by turn-
ing the front sleeve
2 until the drill bit can be
inserted.
–
Insert the drill bit.
–
Hold the retaining ring 3 and firmly turn the
front sleeve 2 in the direction of the arrow un-
til a latching noise can clearly be heard.
–
Check the tight seating by pulling the tool.
