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 2 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 5 forward so
that the "I" is indicated on the switch.
– To switch off the machine, push the On/Off switch 5 to-
ward 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 5 to off. Charge the battery and al-
low it to cool down before restarting the machine. Otherwise
the battery can become damaged.
Working Advice
– Apply the power tool to the workpiece only when switched
on.
– Guide the power tool at an angle of 80 to 90° to the surface
of the sheet metal and do not tilt it to the side.
80–90
˚
– Guide the machine evenly and with light feed in the cutting
direction. Excessive feed significantly reduces the service
life of the saw blade and can cause damage to the power
tool.
– When cutting curves, make sure not to tilt the power tool
laterally and work with low feed rate only.
Maximum Steel Sheet Cutting Capacity

Adjusting Cutter Clearance a
 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.
a
– Loosen the fastening screw 13 for the bottom cutter. Ad-
just the required cutter clearance a with the adjustment
screw 12. The upper cutter 10 and the bottom cutter 11
may not touch each other. Check the clearance with the
setting gauge 14. Retighten the fastening screw 13 for the
bottom cutter with a tightening torque of 3–4 Nm.
Temperature Dependent Overload Protection
If used in accordance with its intended use, the power tool
cannot be overloaded. If the power tool is overloaded or not
kept within the permitted battery temperature range, the
stroke rate is reduced or the power tool switches off. When
the stroke rate is reduced, the power tool will not run at full
stroke rate again until the permitted battery temperature has
been reached. If it automatically shuts down, switch the pow-
er tool off, 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.

The cutter clearance a (gap between the
cutters) depends on the sheet thickness
d
to be cut.
max
The cutter clearance a should be 10 % of
the sheet thickness d
(e. g. 0.1 mm cut-
max
ter clearance for 1 mm sheet thickness).
For softer or more ductile materials, the
clearance a must be decreased; for harder
or more brittle materials, increased.
