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 work-
bench.
Only work with the chip deflector 2 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 serv-
ice centre for Bosch power tools.
Wear protective gloves while working and
pay particular attention to the mains cable.
Take care that cut sheet parts do not bend
toward your body or the mains cable. Sharp
burrs develop at the cut steel sheet and can
cause injuries to the operator or damage the
mains cable. If required, press bending steel
sheet parts away from your body or the
mains cable 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:

Adjusting Cutter Clearance a
Before any work on the machine itself, pull
the mains plug.
The cutter clearance a (gap be-
tween the cutters) depends on
the sheet thickness d
cut.

0.3–0.6 0.10
0.8–1.2 0.25
1.3–1.6 0.30
For softer or more ductile materials, the
clearance a must be decreased; for harder or
more brittle materials, increased.
Loosen the fastening screw 7 for the bottom
cutter. Adjust the required cutter clearance a
with the adjustment screw 6. The upper cutter 4
and the bottom cutter 5 may not touch each oth-
er. Retighten the fastening screw 7 for the bot-
tom cutter with a tightening torque of 3–4 Nm.
