Starting Operation; Working Advice - Bosch Professional GSC 12V-13 Manual

12 | English
The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging process
does not damage the battery.
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
Do not continue to press the On/Off switch after the
u
power tool has automatically switched off. The battery
can be damaged.
Removing the battery
To remove the battery (2), press the battery release
buttons (1) and pull the battery out of the power tool. Do
not use force to do this.
Battery charge indicator
The three green LEDs on the battery charge indicator (4) in-
dicate the battery's state of charge (2). For safety reasons, it
is only possible to check the state of charge when the power
tool is not in operation.
To display the state of charge, press and hold the battery
charge indicator button (3) when the power tool is switched
off.

Operation

Starting Operation

Inserting the Battery
Insert the charged battery (2) into the battery receptacle,
making sure you feel it engage and it is securely locked in
place.
Switching On and Off
To switch on the power tool, slide the on/off switch (5) for-
wards so that I appears on the switch.
To switch off the power tool, slide the on/off switch (5)
backwards so that 0 appears on the switch.

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.
This power tool is not suitable for bench-mounted use.
u
It must not be clamped into a vice or fastened to a work-
bench, for example.
Wear protective gloves during work. Make sure that
u
cut sheet parts are not bent towards your body. Sharp
burrs develop on cut sheets; these can cause injury.
1 609 92A 6N5 | (10.06.2021)
When necessary and while wearing gloves, press bending
sheet parts away from your body.
Apply the machine 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.
Guide the power tool evenly, pushing it gently in the cutting
direction. Applying too much pressure to the power tool will
significantly reduce the service life of application tools and
can damage the power tool.
When cutting curves, make sure not to tilt the power tool lat-
erally and work with low feed rate only.

Adjusting cutter clearance "a"
The clearance a between the cutters should be 10 % of the
maximum sheet thickness (e.g. 0.1 mm cutter clearance for
1 mm sheet thickness).
For softer or more ductile materials, the clearance a must be
decreased; for harder or more brittle materials, it must be in-
creased.
Loosen the fastening screw (12) for the bottom cutter. Ad-
just the requested cutter clearance a with the set screw (11)
for the bottom cutter. The upper cutter (9) and the bottom
cutter (10) may not touch each other.
Check the clearance using the setting gauge (13). Retighten
the fastening screw (12) for the bottom cutter to a tighten-
ing torque of 3–4 Nm.
