Note: Do not use tools without SDS-plus for ham-
mer drilling or chiselling! Tools without SDS-plus
and their drill chucks are damaged by hammer
drilling or chiselling.
The SDS-plus tool holder 1 can easily be ex-
changed against the quick change keyless chuck
10.
Changing the Tool Holder
Dismounting the SDS-plus Tool Holder or the
Quick change keyless chuck (see figure B)
Turn the mode selector switch 6 temporarily to
the "drilling" position in order to lock the tool
holder.
Firmly turn the locking sleeve 3 in the direction of
the arrow and pull off the tool holder 1 or the
quick change keyless chuck 10 toward the front.
After removing, protect the tool holder 1 or the
quick change keyless chuck 10 against contami-
nation. Lightly lubricate the engaging grooves, if
required.
Mounting the SDS-plus Tool Holder or the Quick
change keyless chuck
Turn the locking sleeve 3 in the direction of the
arrow and pull it back at the same time, until the
tool holder 1 or the quick change keyless chuck
10 engages.
The tool holder 1 or the quick change keyless
chuck 10 is automatically locked. Check the lock-
ing effect by pulling the tool holder.
Changing the Tool
With the SDS-plus tool holder, simple and con-
venient tool changing is possible without addi-
tional aids.
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 effect
on the accuracy of the drill hole, as the drill bit
centres itself upon drilling.
The dust protection cap 2 largely prevents the
entry of drilling dust into the tool holder during
operation. When inserting the tool, take care that
the dust protection cap 2 is not damaged.
Bosch Power Tools
A damaged dust protection cap should be
changed immediately. We recommend hav-
ing this carried out by an after-sales service.
Inserting SDS-plus Drilling Tools (see figure C)
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.
Removing SDS-plus Drilling Tools (see figure D)
