Assembly
Fitting the Dust Extraction Attachment
(see figures A1−A2)
– Put the guide bore (13) of the rotary hammer on the
housing guide (12) of the dust extraction attachment and
slide the dust extraction attachment onto the rotary ham-
mer.
The dust extraction attachment must audibly engage. The
markings on the dust extraction attachment and rotary
hammer must align.
– To disconnect the attachment, press and hold the release
button (8) and pull the dust extraction attachment off the
rotary hammer.
Operation
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.

Working advice

Never use the dust extraction attachment without a
u
filter. If the dust extraction attachment is used without a
filter, larger particles of drilling dust can be flung towards
the user and the power tool can be damaged.
Do not use damaged filters (e.g. no cracks, small
u
holes, etc.). Replace any damaged filters immedi-
ately.
Bosch Power Tools
Never carry the power tool by the dust extraction at-
u
tachment.
During operation, hold the power tool with fitted dust
u
extraction attachment not on the dust extraction at-
tachment, but always on the handle and auxiliary
handle of the power tool.
Note: The guide (5) is spring-loaded. The guide can spring
forward when the button (6) for drill bit length adjustment is
pressed.
Hold the power tool firmly with both hands and make
u
sure you have a stable footing. The power tool is more
securely guided with both hands.
Inserting/removing the drill bit (see figure B)
– Press the button (6) for drilling depth adjustment and pull

the guide (5) all the way out.

Adjusting the Guide Length (see figure C)
To ensure that dust is extracted cleanly and the depth stop is
set correctly, the guide (5) must be adjusted so that the tip
of the drill bit is flush at the front with the dust cap /(3).
Note: To store the dust extraction attachment, press the
button (6) and pull the guide (5) all the way out. This re-
lieves the strain on the guide's spring, which increases the
service life of the spring.
Adjusting the Drilling Depth (see figure D)
The button (4) for depth stop adjustment can be used to set
the required drilling depth X.
– Press the button (4) and slide the button on the guide (5)
so that the distance X shown in the illustration matches
your required drilling depth.
– Release the button (4) again.
