Noise/Vibration Information

Measured values determined according to
EN 60745.
Typically the A-weighted noise levels of the prod-
uct are: Sound pressure level 89 dB(A); Sound
power level 100 dB(A). Uncertainty K =1.5 dB.
Wear hearing protection!
Vibration total values (triax vector sum) deter-
mined according to EN 60745:
Cutting wood: Vibration emission value
2
a =10 m/s , uncertainty K=1.5 m/s
h
Cutting sheet metal: Vibration emission value
2
a =11 m/s , uncertainty K=3 m/s
h
The vibration emission level given in this informa-
tion 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 ex-
posure.
The declared vibration emission level represents
the main applications of the tool. However if the
tool is used for different applications, with differ-
ent accessories or poorly maintained, the vibra-
tion emission may differ. This may significantly
increase the exposure level over the total work-
ing 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 total
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.
Selecting a Saw Blade
Use only T-shank saw blades or saw blades with
1/4" universal shank (U-shank). The saw blade
should not be longer than required for the in-
tended cut.
Use a thin saw blade for narrow curve cuts.
Inserting the Saw Blade (see figure A1)
Clean the shank of the saw blade before in-
serting it. An unclean shank cannot be fas-
tened securely.
Push the saw blade holder 9 upward in the direc-
tion of the arrow. Insert the saw blade 8 (teeth in
cutting direction) to the stop into the saw blade
holder.
While inserting the saw blade, pay attention that
the back of the saw blade is positioned in the
groove of the guide roller 7.
Check the tight seating of the saw blade.
A loose saw blade can fall out and lead to
injuries.
Removing the Saw Blade (see figure A2)
Push the saw blade holder 9 upward in the direc-
tion of the arrow and remove the saw blade 8.
