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.
While replacing the saw blade, ensure that the saw
u
blade receptacle is free of material residue, e.g. wood
or metal chips.
Selecting the saw blade
You will find an overview of recommended saw blades at the
end of these operating instructions. Only use saw blades
with a 1/2" universal shank. The saw blade should not be
longer than required for the intended cut.
Inserting the saw blade (see figure C)
Turn the locking sleeve (3) approx. 90° in the direction of
the arrow and hold it firmly. Push the saw blade (1) into the
saw blade receptacle (12). Release the locking sleeve again.
Check that it is seated securely by pulling the saw
u
blade. A loose saw blade can fall out and lead to injuries.
For particular jobs, the saw blade (1) can also be flipped
180° (teeth point upwards) and refitted.
Removing the Saw Blade (see figure D)
Let the saw blade cool down before removing it. There
u
is a risk of injury when touching the hot saw blade.
Turn the locking sleeve (3) approx. 90° in the direction of
the arrow and hold it firmly. Remove the saw blade (1).

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 ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– 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 ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.

Starting Operation

80−100 %
60−80 % Inserting the battery
Note: The use of batteries unsuitable for your power tool can
40−60 %
lead to malfunctions or damage to the power tool.
20−40 %
Press the lock-off button (5) to the right to protect the
5−20 %
power tool from being switched on unintentionally.
0−5 %
Slide the charged battery (4) from below into the foot of the
power tool. Press the battery fully into the base until the bat-
tery is securely locked.
Switching On and Off (see figure E)
To switch on the power tool, press the lock-off switch to the
left (5) first. Then press the on/off switch (6) and keep it
pressed.
The worklight lights up when the on/off switch (6) is lightly
or fully pressed allowing the work area to be illuminated in
poor lighting conditions.
To switch off the power tool, release the on/off switch (6).
Then press the lock-off button (5) to the right again.
Controlling the stroke rate
You can variably adjust the stroke rate of the power tool
when it is on by pressing in the on/off switch (6) to varying
extents.
Applying light pressure to the on/off switch (6) results in a
low stroke rate. Applying increasing pressure to the switch
increases the stroke rate.
The required stroke rate is dependent on the material and
the work conditions and can be determined using practical
tests.
It is recommended that you reduce the stroke rate when
placing the saw blade on the workpiece and when sawing
plastic and aluminium.
During prolonged periods of use at a low stroke rate, the
power tool may heat up significantly. Remove the saw blade
and let the power tool run at the maximum stroke rate for
around three minutes to cool down.

Working Advice

Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
Switch the power tool off immediately if the saw blade
u
becomes blocked.
Tips
When sawing lightweight materials, take into account
u
the statutory provisions and recommendations of the
material manufacturers.
Before sawing into wood, chipboard, building materials,
etc., check for any foreign objects such as nails, screws, etc.
and use a suitable saw blade.
