Adjusting Cutter Clearance a
Before any work on the machine itself (e.g.
maintenance, 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
cut.
The cutter clearance a should be
10 % of the sheet thickness d
a
(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, increased.
Loosen the fastening screw 12 for the bottom
cutter. Adjust the required cutter clearance a
with the adjustment screw 11. The upper cutter
9 and the bottom cutter 10 may not touch each
other. Check the clearance with the setting
gauge 13. Retighten the fastening screw 12 for
the bottom cutter with a tightening torque of
3–4 Nm.
Temperature Dependent Overload Protection
When using the machine as intended for, it can-
not 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 re-
duced stroke rate, the machine will not run at
full stroke rate again until after reaching the per-
mitted battery temperature. In case of automat-
ic 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 45 °C. As an example,
do not leave the battery in the car in summer.
A significantly reduced working period after
charging indicates that the battery is used and
must be replaced.

Maintenance and Cleaning
Before any work on the machine itself (e.g.
maintenance, 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.
For safe and proper working, always keep
the machine and ventilation slots clean.
Replacing the blade (see figure A)
The upper cutter 9 and the bottom cutter 10 are
identical, have four cutting edges each, and can
be exchanged with each other.
Turn or replace the cutters in good time. Only
sharp application tools achieve good cutting
capacity and make the machine last longer.
To replace the upper cutter 9, loosen the fasten-
ing screw 8; to replace the bottom cutter 10,
loosen the fastening screw 12.
Turn the cutter by 90° or install a new cutter.
When installing the bottom cutter 10, pay
attention that it faces against the adjustment
screw 11.
Note: Turn the cutter only in the direction indi-
cated in the figure and insert a new cutter only
in the position shown in the figure. Cutting is
not possible with an incorrectly inserted cutter.
