Working Advice
Before any work on the machine itself, pull
the mains plug.
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.
Apply the power tool to the workpiece only
when switched on.
Hold the power tool inclined in an angle of 15°
to the surface of the steel sheet and do not tilt
it laterally.
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.
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.
When cutting curves, make sure not to tilt the
power tool laterally and work with low feed rate
only.
For internal cuts a pilot hole of 15 mm (blade for
straight cuts) or 8 mm (blade for curved cuts) is
necessary.

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:
15˚
Lubricating/Cooling the Cutters
In order to extend the lives of blade and cutter
bar you should use a lubricant with a good cool-
ing capacity (e.g. cutting oil).
Apply a trail of lubricant beads onto the top side
of the metal sheet alongside the intended cut-
ting line. For long periods of continual use or for
work with high frictional wear (e.g. when cut-
ting aluminium), the cutting head should be im-
mersed into a container with lubricant in regular
intervals.
