Replacing/Inserting the Saw Blade
 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.
 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. 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 B)
 Clean the shank of the saw blade before
inserting it. An unclean shank cannot be fastened
securely.
Insert the saw blade 13 into the stroke rod 11 until it latches.
The lever 20 automatically snaps to the rear and the saw
blade is locked. Do not manually press the lever 20 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
10.
 Check the tight seating of the saw blade. A
loose saw blade can fall out and lead to injuries.
Ejecting the Saw Blade (see figure C)
 When ejecting the saw blade, hold the
machine in such a manner that no persons or
animals can be injured by the ejected saw
blade.
Turn the lever 20 forward towards the contact protector 21
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
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment addi-
tives (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 D–E)
Insert the vacuum connection 18 into the opening of base
plate 9.
Place a vacuum hose 22 (accessory) onto the vacuum con-
nection 18. Connect the vacuum hose 22 with a vacuum
cleaner (accessory).
To enable optimum dust extraction, use the splinter guard 14
if possible.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Place the extraction hood 15 onto the contact protector 21.
Splinter Guard (see figure F)
The splinter guard 14 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 14 into base plate 9 from the front.
The splinter guard 14 can also be fitted with the mounted
plastic sliding shoe 12.
Sliding Shoe (see figure G)
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 19.
Then press the power tool onto the plastic sliding shoe 12
until it engages.
When using the plastic sliding shoe 12, the splinter guard 14
is inserted not into the base plate 9, but rather the sliding
shoe.
