Working Advice

– 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
The maximum steel sheet cutting capacity d
the strength properties of the material to be cut.
The machine allows for cutting of metal sheet to the following
thicknesses:
Material Max. strength property

Aluminium 250
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.
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
ter clearance for 1 mm sheet thickness).
a
For softer or more ductile materials, the
clearance a must be decreased; for harder
or more brittle materials, increased.
– 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
If used in accordance with its intended use, the power tool
cannot be overloaded. If the power tool is overloaded or not
kept within the permitted battery temperature range, the
stroke rate is reduced or the power tool switches off. When
the stroke rate is reduced, the power tool will not run at full
stroke rate again until the permitted battery temperature has
been reached. If it automatically shuts down, switch the pow-
er tool off, allow the battery to cool down, then switch the
power tool back on.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Store the battery only within a temperature range between
–20 °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 upper cutter 10 and the bottom cutter 11 are identical,

have four cutting edges each, and can be exchanged with
each other.
Turn or replace the cutters in good time. Only sharp applica-
tion tools achieve good cutting capacity and make the ma-
chine last longer.
– To replace the upper cutter 10, loosen the fastening screw
9; to replace the bottom cutter 11, loosen the fastening
screw 13.
– Turn the cutter by 90° or install a new cutter. When install-
ing the bottom cutter 11, pay attention that it faces against
the adjustment screw 12.
Note: Turn the cutter only in the direction indicated in the
(e. g. 0.1 mm cut-
max
figure and insert a new cutter only in the position shown in the
figure. Cutting is not possible with an incorrectly inserted
cutter.
– Retighten the fastening screw 9 for the upper cutter and
the fastening screw 13 for the bottom cutter with a tighten-
ing torque of 3–4 Nm. Check the cutter clearance a (see
"Adjusting Cutter Clearance a", page 12).
Upper cutter 10 and bottom cutter 11 may not be reground.
