Note: Use of batteries not suitable for the machine can lead to
malfunctions of or cause damage to the power tool.
Insert the charged battery 6 into the handle until it can be felt
to engage and faces flush against the handle.
Switching On and Off
To start the machine, push the On/Off switch 4 forward so
that the "I" is indicated on the switch.
To switch off the machine, push the On/Off switch 4 toward
the rear so that the "0" is indicated on the switch.
To save energy, only switch the power tool on when using it.
The lithium-ion battery is protected against deep discharging
by the "Electronic Cell Protection (ECP)". When the battery is
empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.
Note: If the machine should automatically switch off because
of a discharged or overheated battery, make sure to set the
machine's On/Off switch 4 to off. Charge the battery and al-
low it to cool down before restarting the machine. Otherwise
the battery can become damaged.

Working Advice

 Do not strain the machine so heavily that it comes to a
standstill.
 Never touch the blade during operation 10.
The cutting performance of the machine depends on the ma-
terials to be cut and on the charging condition of the battery.
Depending on the charge condition of the battery, excessive
feed considerably reduces the performance capability.
Always keep the blade free and clean of material remainders.
The guide edge 12 may not become wedged during cutting
and must be aligned parallel to the cutting surface.
Improper use of the blade will cause it to become blunt.
Thin materials, such as fabrics, can be pulled into the machine
during cutting and become wedged. Therefore, do not apply
too much pressure with such materials in order to achieve
good cutting results. During cutting, apply sufficient tension
while holding fabrics and cut slowly.
Do not remove drawn in material during operation and switch
the power tool off first with the On/Off switch 4.
Optimum cutting results are best determined through practi-
cal testing.
Adjusting the Blade Guard
 Never operate the machine without the blade guard 3.
For optimal protection of your fingers against injuries, the
blade guard must be adjusted to the material thickness being
cut before each work step.
– Loosen the knurled screw 1.
– Adjust blade guard 3 in such a manner that it faces loosely
against the material to be cut.
– Tighten knurled screw 1 again.
Note: Position the blade guard 3 completely down each time
after using the machine and before carrying out an inspection
or maintenance.

"Cut Control" Cutting-line Mark
The red line on the blade guard ("Cut Control" cutting-line
mark 2) indicates the cutting line of the blade 10.
This allows for precise guiding of the machine alongside the
cutting line marked on the material.
Temperature Dependent Overload Protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or not kept within the
permitted battery temperature range, the speed is reduced or
the power tool switches off. At reduced speed, the power tool
will run again at full speed once the permitted battery temper-
ature is reached or the load is reduced. During automatic
shut-down, switch off the power tool, allow the battery to cool
down, then switch the power tool back on.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Store the battery only within a temperature range between
–20 °C and 50 °C. As an example, do not leave the battery in
the car in summer.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Observe the notes for disposal.

Maintenance and Service

Maintenance and Cleaning

 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
 For safe and proper working, always keep the machine
and ventilation slots clean.
While cutting, material residue can accumulate under the
blade guard.
Clean the blade guard 3 regularly using a brush or lightly mois-
tened cloth.
