Assembly
Before any work on the machine itself, pull
the mains plug.
Replacing/Inserting the Saw Blade
When mounting the saw blade, wear protec-
tive gloves. Danger of injury when touching
the saw blade.
Selecting a Saw Blade
An overview of recommended saw blades can
be found at the end of these instructions. Use
only T-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)
If required, remove the dust cover 12 (see "Dust
Cover").
Insert the saw blade 10 into the stroke rod 14
until it latches. The SDS lever 15 automatically
snaps to the rear and the saw blade is locked.
Do not manually press the lever 15 toward the
rear, otherwise you could damage the machine.
While inserting the saw blade, pay attention that
the back of the saw blade is positioned in the
groove of the guide roller 9.
Check the tight seating of the saw blade. A
loose saw blade can fall out and lead to inju-
ries.
Ejecting the Saw Blade (see figure B)
When ejecting the saw blade, hold the ma-
chine in such a manner that no persons or
animals can be injured by the ejected saw
blade.
Turn the SDS lever 15 forward towards the con-
tact protector 11 to the stop. The saw blade is
released and ejected.

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.
– As far as possible, use a dust extraction
system suitable for the material.
– 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.
Prevent dust accumulation at the work-
place. Dusts can easily ignite.
Dust Cover
Mount the dust cover 12 before connecting the
machine to the dust extraction.
Place the dust cover from the front into the
guide so that it latches.
Remove the dust cover for applications without
dust extraction as well as when performing mi-
tre cuts. For this, lightly push the end of the dust
cover together and pull it off to the front.
Connecting the Dust Extraction
(see figures C–D)
Depending on the machine model, place a vacu-
um hose 16 (accessory) either directly onto the
vacuum connection 5 or cut off the old hose
end, screw the extraction adapter 17 (accesso-
ry) onto the hose end and insert it directly into
the vacuum connection 5. Connect the vacuum
hose 16 with a vacuum cleaner (accessory). An
overview for the connection of various vacuum
cleaners can be found at the end of these in-
structions.
Switch the saw dust blower off when a dust ex-
traction system is connected (see "Sawdust
Blower Device").
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
