Operation
Starting Operation
Inserting the Battery
Use only original Bosch lithium ion batter-
ies with the voltage listed on the nameplate
of your power tool. Using other batteries can
lead to injuries and pose a fire hazard.
Note: Use of batteries not suitable for the ma-
chine can lead to malfunctions of or cause dam-
age 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 toward the rear so that the "0" is indi-
cated on the switch.
The lithium ion battery is protected against
deep discharging by the "Electronic Cell Protec-
tion (ECP)". When the battery is empty, the ma-
chine 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 bat-
tery, make sure to set the machine's On/Off
switch 5 to off. Charge the battery and allow it to
cool down before restarting the machine. Other-
wise the battery can become damaged.
Working Advice
The power tool is not suitable for stationary
operation. For example, it may not be
clamped in a vice or fastened on a workbench.
Only work with the chip deflector 6 mount-
ed. Take care that the chip deflector is not
damaged or bent. Danger of injury when
working without the chip deflector or when it
is damaged. Have a damaged chip deflector
replaced immediately by an after-sales service
centre for Bosch power tools.

Wear protective gloves while working. Take
care that cut sheet parts do not bend toward
your body. Sharp burrs develop at the cut
steel sheet and can cause injuries to the oper-
ator. If required, press bending steel sheet
parts away from your body using gloves.
Apply the power tool to the workpiece only
when switched on.
80–90
˚
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.
Guide the machine evenly and with light feed in
the cutting direction. Excessive feed significant-
ly 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
The maximum steel sheet cutting capacity d
depends on the strength properties of the mate-
rial to be cut.
The machine allows for cutting of metal sheet to
the following thicknesses:
