Inserting the saw blade (see figure A)
Use only clean saw blades. Make sure that the saw
u
blade receptacle is free of chips and sawdust.
Use the locking lever (10) to open the cover (9) of the saw
blade receptacle. Insert the saw blade as shown in the fig-
ure. Make sure that the drive shaft and the end of the saw
blade fit in the recess on the saw blade receptacle (12).
Close the cover of the saw blade receptacle and lock it with
the locking lever. You should hear the locking lever click into
place.
The chain of the saw blade is tensioned automatically.
If the chain slips through or becomes detached from the
guide unit, open and close the cover (9) of the saw blade re-
ceptacle.
Removing the saw blade
Open the locking lever (10) fully open the cover (9) of the
saw blade receptacle. Remove the saw blade.
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.
Operation
Never bend the saw blade

Starting Operation
Inserting the battery
Note: The use of batteries unsuitable for your power tool can
lead to malfunctions or damage to the power tool.
Insert the charged battery (5) into the battery receptacle un-
til you feel it engage and it is securely locked in place.
Switching on/off
To switch on the power tool, press the lock-off button (3) to
the left or right. Then press the on/off switch (4) and keep it
pressed.
Once the power tool is switched on, you can release the lock-
off button (3).
To switch off the power tool, release the on/off switch (4).

Controlling the sawing speed
You can control the speed of the power tool when switched
on by how hard you press the on/off switch (4). The speed is
continuously variable.
The sawing speed required depends on the material and the
working conditions; it can be ascertained through practical
tests.
It is advisable to reduce the sawing speed when placing the
saw blade on the workpiece.
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.
Always use a sturdy support when working on small or
u
thin workpieces.
Make sure you always cut from front to back (see
u
figure C) or from top to bottom (see figure D) when
sawing.
Do not carry the power tool on your wrist. The suspen-
u
sion strap is intended for storage only (see figure F).
Saw with moderate pressure in order to achieve optimal and
precise cutting results. Applying additional pressure in-
creases performance.
Switch the power tool off immediately if the saw blade jams.
Widen the sawing gap slightly with a suitable tool and pull
the power tool out.
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or the permitted bat-
tery temperature is exceeded, the electronics of the power
tool will switch off until the temperature returns to within the
optimum operating temperature range.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of −20 to
50 °C. Do not leave the battery in your car in the summer, for
example.
Occasionally clean the ventilation slots on the battery using a
soft brush that is clean and dry.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.
