The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging process
does not damage the battery.
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
Do not continue to press the On/Off switch after the
u
power tool has automatically switched off. The battery
can be damaged.
The battery (3) is equipped with two locking levels to pre-
vent the battery from falling out if the battery release button
(4) is pressed unintentionally. The battery is held in place by
a spring when fitted in the power tool.
To remove the battery (3), press the release button (4) and
pull the battery out of the power tool. Do not use force to
do this.
Battery charge indicator
The green LEDs on the battery charge indicator (18) indic-
ate the battery's state of charge (3). For safety reasons, it is
only possible to check the state of charge when the power
tool is not in operation.
Press the button for the battery charge indicator (17) to
show the state of charge. This is also possible when the bat-
tery is removed.
If no LED lights up after pressing the button for the battery
charge indicator (17), then the battery is defective and must
be replaced.

Inserting/changing the saw blade
When fitting or changing the saw blade, wear protect-
u
ive gloves. Blades are sharp and can become hot when
used for prolonged periods of time.
Selecting the saw blade
You will find an overview of recommended saw blades at the
end of these operating instructions. Only use saw blades
1 609 92A 4TM | (04.04.2019)
with single lug shank (T shank). The saw blade should not be
longer than required for the intended cut.
Use a narrow saw blade when sawing tight curves.
Inserting the saw blade (see figure C)
Clean the shaft on the saw blade before inserting it.
u
A dirty shaft cannot be securely fixed in place.
Push the saw blade (10), with the teeth in the cutting direc-
tion, into the saw blade receptacle (19) until it clicks into
place. The SDS lever (11) automatically springs back and
the saw blade is locked in place. Do not push the lever (11)
back by hand as you could damage the power tool.
Make sure when inserting the saw blade that the back of the
saw blade is in the groove on the guide roller (9).
Check that the saw blade is seated securely. A loose
u
saw blade can fall out and lead to injuries.
Ejecting the saw blade (see figure D)
When ejecting the saw blade, hold the power tool in
u
such a manner that no persons or animals can be in-
jured by the ejected saw blade.
Turn the SDS lever (11) as far as it will go in the direction of
the shock protection guard (13). The saw blade is released
and ejected.
Glide shoe (see figure E)
The plastic guide plate (6) of the base plate (7) reduces
scratching on sensitive surfaces. Use the steel glide
shoe (20) when machining metal.
Fit the steel glide shoe (20) by sliding it onto the base
plate (7) from the front.
The plastic guide plate (6) should be replaced if it is worn.
Capacity
60−100 %
Anti-splinter guard (see figure F)
30−60 %
The anti-splinter guard (21) (accessory) can prevent splin-
5−30 %
tering of the surface while sawing wood. The anti-splinter
guard can only be used with certain saw blade types and only
0−5 %
at a cutting angle of 0°. When sawing with the anti-splinter
guard, the base plate (7) must not be moved to the rear for
sawing close to edges.
Capacity
Slide the anti-splinter guard (21) into the base plate (7)
80−100 %
from the front.
60−80 %
40−60 %
Dust/Chip Extraction
20−40 %
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
5−20 %
Touching or breathing in this dust can trigger allergic reac-
0−5 %
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
