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.
Press the SDS clamping lever 8 sideward to the
stop. The saw blade 12 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.
– 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.
Splinter Guard (see figure C)
The splinter guard 14 (accessory) can prevent
fraying of the surface while sawing wood. The
splinter guard can only be used for certain saw
blade types and only for cutting angles of 0°.
When sawing with the splinter guard, the base
plate 5 must not be moved back for cuts that are
close to the edge.
Press the splinter guard 14 from the bottom into
the base plate 5.
When using the sliding shoe 15, the splinter
guard 14 is not inserted into the base plate 5,
but into the sliding shoe.

Sliding Shoe
When working surfaces that are easily
scratched, the sliding shoe 15 can be attached
onto the base plate 5 in order to prevent the sur-
face from being scratched.
To attach the sliding shoe 15, insert it at the
front of the base plate 5, push the rear part up-
ward and allow it to latch.
Operation
Operating Modes
Before any work on the machine itself (e. g.
maintenance, tool change, etc.) as well as
during transport and storage, remove the
battery from the power tool. There is danger
of injury when unintentionally actuating the
On/Off switch.
Orbital Action Settings
The four orbital action settings allow for optimal
adaptation of cutting speed, cutting capacity
and cutting pattern to the material being sawed.
The orbital action can be adjusted with the ad-
justing lever 7, even during operation.
Setting 0 No orbital action
Setting I Small orbital action
Setting II Medium orbital action
Setting III Large orbital action
The optimal orbital action setting for the respec-
tive application can be determined through
practical testing. The following recommenda-
tions apply:
– Select a lower orbital action setting (or
switch it off) for a finer and cleaner cutting
edge.
– For thin materials such as sheet metal,
switch the orbital action off.
– For hard materials such as steel, work with
low orbital action.
– For soft materials and when sawing in the di-
rection of the grain, work with maximum or-
bital action.
