Assembly

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
An overview of recommended saw blades can
be found at the beginning of these operating in-
structions. Use only saw blades with ½" univer-
sal 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)
Press the SDS clamping lever 5 forward and
guide the saw blade 1 behind the clamping plate
12 into the saw blade holder 3. Release the SDS
clamping lever 5.
Check the tight seating by pulling on the
saw blade. A loose saw blade can fall out and
cause injury.
For certain work, the saw blade 1 can also be
turned through 180° (with the teeth pointed up-
wards) and re-inserted again.
Removing the Saw Blade
Before removing, allow the saw blade to
cool down. Danger of injury when touching
the hot saw blade.
Press the SDS clamping lever 5 forward and pull
out the saw blade 1. Release the SDS clamping
lever 5.

Dust/Chip Extraction

Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
1 609 929 R78 | (29.1.10)
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.

Operation

Operating Modes
Before any work on the machine itself, pull
the mains plug.
Pivoting and Retractable Footplate
(see figure B–C)
Due to its movability, the adjustable footplate 2
adapts to the required angular position of the
surface.
Depending on the application and the saw blade
being used, the footplate 2 can be moved varia-
bly in length direction. Loosen the screws 13
with Allen key 9 and move the footplate 2 to the
requested position. Tighten the screws 13 again
and check if the footplate 2 is tightly seated.
Utility Hook (see figure D)
Your tool is equipped with a utility hook 6 for
hanging it, e. g., to a ladder, etc. Simply fold out
the utility hook 6 to the required position.
When the tool is hanging by the utility hook,
ensure that the saw blade is protected
against unintended contact. Danger of inju-
ry.
Fold the utility hook 6 back in again when you
are ready to continue working.
