Noise/Vibration Information
Measured sound values determined according to EN 60745.
Typically the A-weighted noise levels of the product are:
Sound pressure level 95 dB(A); Sound power level
106 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values a (triax vector sum) and uncertainty K
h
determined according to EN 60745:

The vibration emission level given in this information 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 represents the main ap-
plications 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 significantly in-
crease the exposure level over the total working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may signif-
icantly 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 hands warm, organise work patterns.

Assembly
Replacing/Inserting the Saw Blade
 Before any work on the machine itself, pull the mains
plug.
 When mounting the saw blade, wear protective 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
An overview of recommended saw blades can be found at the
beginning of these instructions. Use only ½" universal shank
saw blades. 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 locking sleeve 4 approx. 90° in the direction of the
2
,
arrow and hold. Push the saw blade 1 into the saw blade hold-
2 2
, K=1.5 m/s .
er 3. Release the locking sleeve 4 again.
 Check the tight seating of the saw blade. A loose saw
blade can fall out and lead to injuries.
For certain work, the saw blade 1 can also be turned through
180° (with the teeth pointed upwards) and re-inserted again.
Removing the Saw Blade (see figure B)
 Before removing, allow the saw blade to cool down.
Danger of injury when touching the hot saw blade.
Turn the locking sleeve 4 approx. 90° in the direction of the
arrow and hold. Remove the saw blade 1.
Dust/Chip Extraction
 Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Operation
Operating Modes
 Before any work on the machine itself, pull the mains
plug.
Pivoting and Retractable Footplate (see figure C)
Due to its movability, the adjustable footplate 2 adapts to the
required angular position of the surface.
Depending on the saw blade being used and the application,
the footplate 2 can be moved in lengthway direction in three
steps. Press the release button for the footplate 9 and slide
the footplate 2 to the required position. Release the footplate
release button 9 and check that the footplate 2 is firmly
latched. Slide the footplate 2 as required until it is firmly
latched.
