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.
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 di-
rection 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.
Precise cuts are only possible when the guide
roller 7 faces closely but not too tight against
the back of the saw blade (the saw blade 8 may
not be bent by the guide roller). If required,
loosen screw 12 and move the holder 11 of the
guide roller in such a manner that the guide roll-
er faces closely against the back of the saw
blade. Tighten screw 12 again.
Check the tight seating of the saw blade. A
loose saw blade can fall out and lead to inju-
ries.
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.

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.
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.
– Use dust extraction whenever possible.
– 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.
Connecting the Dust Extraction
Place a vacuum hose 3 (accessory) onto the vac-
uum connection 4. Connect the vacuum hose 3
with a vacuum cleaner (accessory). An overview
for the connection of various vacuum cleaners
can be found at the end of these instructions.
