The specifications apply to a rated voltage [U] of 230 V. These specifications may vary at different voltages and in country-
specific models.

Noise/vibration information

Noise emission values determined according to
EN 62841-2-5.
Typically, the A-weighted noise level of the power tool is:
Sound pressure level 94 dB(A); sound power level
105 dB(A). Uncertainty K = 3 dB.
Wear hearing protection!
Vibration total values a (triax vector sum) and uncertainty K
h
determined according to EN 62841-2-5:
2
Sawing wood: a = 3.0 m/s , K = 1.5 m/s
h
The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure and may be used to com-
pare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value repres-
ent the main applications of the power tool. However, if the
power tool is used for other applications, with different ap-
plication tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the

and organising workflows correctly.
Fitting
Only use saw blades the maximum permitted speed of
u
which is higher than the no-load speed of the power
tool.

Inserting/changing the circular saw blade

2
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Wear protective gloves when fitting the saw blade.
u
Danger of injury when touching the saw blade.
Do not use abrasive wheels as the application tool un-
u
der any circumstances.
Only use saw blades that match the specifications
u
given in this operating manual and that are tested and
marked in accordance with EN 847-1
Selecting the saw blade
You will find an overview of recommended saw blades at the
end of these operating instructions.
Removing the saw blade (see figure A)
To change tools, we recommend that you place the power
tool down on the front side of the motor housing.
– Press and hold the spindle lock button (5).
Do not press the spindle lock button (5) while the saw
u
spindle is moving. The power tool may become damaged
if this happens.
