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 92 dB(A); sound power level
103 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 < 1.4 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 detailed in EN 62841
and may be used to compare power tools. They may also be
used for a preliminary estimation of vibration and noise
emissions.
The given vibration level and noise emission value represent
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 the hands warm,
and organising workflows correctly.

mm 184
given in this operating manual and on the power tool.
mm 184 The permitted speed of the application tool must be at
u
least equal to the maximum speed marked on the
mm 2.0
power tool. If accessories run faster than their rated
mm 15.9
speed, they may break and fly off.

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 (4).
Do not press the spindle lock button (4) while the saw
u
spindle is moving. The power tool may become damaged
if this happens.
– Use the hex key (17) to undo the clamping bolt (18) in ro-
tational direction ➊.
– Swing the retracting blade guard (11) back and hold on
to it firmly.
– Remove the clamping flange (19) and the saw blade (20)
from the saw spindle (22).

Selecting the saw blade
You will find an overview of recommended saw blades at the
end of these operating instructions.
Fitting 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.
– Clean the saw blade (20) and all the clamping elements
to be fitted.
– Swing the retracting blade guard (11) back and hold on
to it firmly.
– Place the saw blade (20) on the mounting flange (21).
The cutting direction of the teeth (direction of the arrow
on the saw blade) must match the rotational direction of
the arrow on the protective guard (11).
– Attach the clamping flange (19) and screw in the clamp-
ing bolt in rotational direction ➋. Ensure that the mount-
ing flange (21) and clamping flange (19) are installed in
the correct position.
– Press and hold the spindle lock button (4).
