Noise/Vibration Information
Measured sound values determined according
to EN 60745.
Typically the A-weighted noise levels of the
product are: Sound pressure level 95 dB(A);
Sound power level 106 dB(A). Uncertainty
K =3 dB.
Wear hearing protection!
Vibration total values (triax vector sum) deter-
mined according to EN 60745:
Vibration emission value a
h
<2.5 m/s 2 , Uncer-
tainty K =1.5 m/s 2 .
The vibration emission level given in this infor-
mation sheet has been measured in accordance
with a standardised test given in EN 60745 and
may be used to compare one tool with another.
It may be used for a preliminary assessment of
exposure.
The declared vibration emission level repre-
sents the main applications of the tool. However
if the tool is used for different applications, with
different accessories or poorly maintained, the
vibration emission may differ. This may signifi-
cantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibra-
tion should also take into account the times
when the tool is switched off or when it is run-
ning but not actually doing the job. This may sig-
nificantly reduce the exposure level over the to-
tal working period.
Identify additional safety measures to protect
the operator from the effects of vibration such
as: maintain the tool and the accessories, keep
the hands warm, organisation of work patterns.

the mains plug.
f When mounting the saw blade, wear protec-
tive gloves. Danger of injury when touching
the saw blade.
f Only use saw blades that correspond with
the characteristic data given in the operat-
ing instructions.
f Do not under any circumstances use grind-
ing discs as the cutting tool.
Selecting a Saw Blade
An overview of recommended saw blades can
be found at the end of this manual.
Removal of the Saw Blade (see figure A)
For changing the cutting tool, it is best to place
the machine on the face side of the motor hous-
ing.
– Press the spindle lock button 4 and keep it
pressed.
f The spindle lock button 4 may be actuated
only when the saw spindle is at a standstill.
Otherwise, the power tool can be damaged.
– With the Allen key 6, unscrew the clamping
bolt 19 turning in rotation direction n.
– Tilt back the retracting blade guard 12 and
hold firmly.
– Remove the clamping flange 20 and the saw
blade 21 from the saw spindle 23.
