Noise/Vibration Information
Noise emission values determined according to
EN 60745-2-3.
Typically the A-weighted noise level of the power tool are: 93
dB(A); sound power level 104 dB(A). Uncertainty K = 3 dB.

The vibration level given in these instructions has been
measured in accordance with a standardised measuring pro-
cedure and may be used to compare power tools. It can also
be used for a preliminary estimation of exposure to vibra-
tion.
The stated vibration level applies to the main applications of
the power tool. However, if the power tool is used for differ-
ent applications, with different application tools or poorly
maintained, the vibration level may differ. This can signific-
antly increase the exposure to vibration over the total work-
ing period.
To estimate the exposure to vibration accurately, the times
when the tool is switched off or when it is running but not ac-
tually being used should also be taken into account. This can
significantly reduce the exposure to vibration over the total
working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping the hands warm,
and organising workflows correctly.

Note: If the grinding disc breaks during operation or the

Adjust the position of the protective guard (7) to meet the
requirements of the operation. To do this, push the unlock-
ing lever (1) upward and rotate the protective guard (7) into
the required position.
Always position the protective guard (7) such that the
u
two cams on the unlocking lever (1) engage in the
corresponding openings on the protective guard (7).
Adjust the protective guard (7) such that sparking in
u
the direction of the operator is prevented.
The protective guard (7) must only be adjustable
u
while the unlocking lever (1) is actuated. Otherwise,
the power tool must not be used any more under any
circumstances and must be sent to the after-sales ser-
vice.
Note: The coding cams on the protective guard (7) ensure
that only a protective guard that is suitable for the power
tool can be fitted.
Extraction guard for cutting with a guide block
The extraction guard for cutting with a cutting guide (19) is
fitted in the same way as the protective guard for grinding.
By securing the auxiliary handle (5) with the clip through the
extraction guard on the gearbox housing, the power tool is
firmly attached to the extraction guard. A suitable Bosch
dust extractor can be connected to the extraction guard with
a cutting guide (19). To do so, insert the vacuum hose with
dust extraction adapter into the provided receiving connec-
tion of the extraction guard.
Note: The friction generated by the dust in the vacuum hose
and accessory during extraction causes an electrostatic

Place the protective guard
(7) onto the holder on the
power tool until the coding
cams of the protective guard
are aligned with the holder.
When doing so, press and
hold the unlocking lever (1).
Press the protective guard
(7) onto the spindle collar un-
til the shoulder of the pro-
tective guard is sitting on the
flange of the power tool and
rotate the protective guard
until it audibly clicks into
place.
