Protection class
The specifications apply to a rated voltage [U] of 230 V. These spe-
cifications may vary at different voltages and in country-specific mod-
els.
Turn-on transients cause brief drops in voltage. Interference with
other tools may occur in the event of unfavourable conditions in the
electricity supply. Malfunctions are not to be expected for system im-
pedances below 1.539 ohm.

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 96 dB(A); sound power level
107 dB(A). Uncertainty K = 3 dB.
Wear hearing protection
Total vibration values a (triax vector sum) and uncertainty K
h
determined according to EN 62841-2-5:
2
Sawing wood: a < 2.5 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

power tool and application tools, keeping their hands warm,
and organising workflows correctly.

To change tools, we recommend that you place the power
tool down on the front side of the motor housing.
– Clean the saw blade (20) and all the clamping elements
– Swing the retracting blade guard (11) back and hold on
– Place the saw blade (20) on the saw spindle with mount-
– Attach the clamping flange (19) and screw in the clamp-
– Press and hold the spindle lock button (4).
– Use the hex key (17) to tighten the clamping bolt (18) in
Only use saw blades the maximum permitted speed of
which is higher than the no-load speed of the power
tool.
Pull the plug out of the socket before carrying out any
work on the power tool.
Wear protective gloves when fitting the saw blade.
Danger of injury when touching the saw blade.
Only use saw blades that match the specifications
given in this operating manual and that are tested and
marked in accordance with EN 847-1
Do not use abrasive wheels as the application tool un-
der any circumstances.
Do not press the spindle lock button (4) while the saw
spindle is moving. The power tool may become damaged
if this happens.
