Ejecting the Saw Blade (see figure B)
 When ejecting the saw blade, hold the ma-
chine in such a manner that no persons or an-
imals can be injured by the ejected saw blade.
Turn the SDS lever 21 forward towards the contact
protector 22 to the stop. The saw blade is released
and ejected.
Dust/Chip Extraction
 Dust 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 dust can cause allergic reac-
tions and/or lead to respiratory infections of the
user or bystanders.
Certain dust, such as oak or beech dust, is con-
sidered 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 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.
Dust can easily ignite.
Connecting the Dust Extraction
(see figures C – E)
Insert the vacuum connection 18 into the opening
of base plate 9.
Place a vacuum hose 23 (accessory) onto the vac-
uum connection 18. Connect the vacuum hose 23
with a vacuum cleaner (accessory).
To enable optimum dust extraction, use the splin-
ter guard 15 if possible.
The vacuum cleaner must be suitable for the mate-
rial being worked.
When vacuuming dry dust that is especially detri-
mental to health or carcinogenic, use a special vac-
uum cleaner.
Place the extraction hood 16 onto the contact pro-
tector 22.
Splinter Guard (see figure E)
The splinter guard 15 can prevent fraying of the
surface while sawing wood. The splinter guard can
only be used with certain saw blade types and only
at a cutting angle of 0 °.
Insert the splinter guard 15 into base plate 9 from
the front.
The splinter guard 15 can also be fitted with the
mounted plastic sliding shoe 12.

Sliding Shoe (see figure F)
When working with sensitive surfaces, use the
plastic sliding shoe 12.
To put on the plastic sliding shoe 12, place the
front edge of the base plate 9 under the nose of the
plastic sliding shoe 20. Then press the power tool
onto the plastic sliding shoe 12 until it engages.
When using the plastic sliding shoe 12, the splinter
guard 15 is inserted not into the base plate 9, but
rather the sliding shoe.
Operation
Operating Modes
 Before any work on the machine itself (e. g.
maintenance, tool change, etc.) as well as dur-
ing 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 adjustable orbital action allows for optimal ad-
aptation of cutting speed, cutting capacity and cut-
ting pattern to the material being worked.
The orbital action can be adjusted with the adjust-
ing lever 8, even during operation.
Orbital action switched off
(level 0):
Orbital action level I:
Orbital action level II:
The optimal orbital action setting for the respective
application can be determined through practical
testing. The following recommendations 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 direc-
tion of the grain, work with maximum orbital ac-
tion.
Adjusting the Cutting Angle (see figure G)
The base plate 9 can be swivelled by 45° to the left
or right for mitre cuts.
Remove the vacuum connection 18.
In mitre angle 0 ° there is a pin in a corresponding
recess.
Loosen the screw 24 with the hex key 25 until you
can slide the base plate 9 in toward the battery 1.
Let the pin slide into the guide groove.
No orbital action
Small orbital action
Large orbital action
