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
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 mounted. 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 im-
mediately 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 operator. If required, press bending steel sheet
parts away from your body using gloves.
– 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
When using the machine as intended for, it cannot be subject
to overload. In case of excessive load or when not within the
permitted battery temperature range of 0–70 °C, the stroke
rate is reduced or the machine switches off. With reduced
stroke rate, the machine will not run at full stroke rate again
until after reaching the permitted battery temperature. In
case of automatic shut-off, switch the machine off, allow the
battery to cool down and then switch the machine on again.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Store the battery only within a temperature range between
0 °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.
