Noise/Vibration Information

Measured values determined according to
EN 60745.
Typically the A-weighted noise levels of the
product are: Sound pressure level 92 dB(A);
Sound power level 103 dB(A). Uncertainty
K =3 dB.
Wear hearing protection!
Vibration total values (triax vector sum) deter-
mined according to EN 60745:
Cutting wood: Vibration emission value
2
a =16 m/s , Uncertainty K=2.5 m/s
h
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.

Replacing/Inserting the Saw Blade
Before any work on the machine itself, pull
the mains plug.
When mounting the saw blade, wear protec-
tive gloves. Danger of injury when touching
the saw blade.
When changing the saw blade, take care
that the saw blade holder is free of material
residue, e. g. wood or metal shavings.
Selecting a Saw Blade
Use only saw blades suitable for the material be-
ing worked.
An overview of recommended saw blades can
be found at the beginning of these operating in-
structions. Use only saw blades with single-nose
shank. The saw blade should not be longer than
required for the intended cut.
Use a thin saw blade for narrow curve cuts.
Inserting the Saw Blade (see figure A)
Turn the SDS lever 3 approx. 180° in clockwise
direction to the stop and insert the saw blade 1
behind the clamping plate 4. Release the SDS le-
ver 3, checking at the same time that the pin on
the saw blade holder is engaged into the inser-
tion hole of the saw blade.
Check the tight seating of the saw blade. A
loose saw blade can fall out and lead to inju-
ries.
For certain work, the saw blade 1 can also be
turned through 180° (with the teeth pointed up-
wards) and re-inserted again.
