To
switch off
the machine, push the On/Off switch
5
toward the rear so that the
“0”
is indicated on the
switch.
The lithium ion battery is protected against deep dis-
charging by the “Electronic Cell Protection (ECP)”.
When the battery is 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 over-
heated battery, make sure to set the
machine’s On/Off switch
5
to off. Charge the
battery and allow it to cool down before
restarting the machine. Otherwise the battery
can become damaged.
Working Advice
❏
The power tool is not suitable for station-
ary 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 immediately by an after-sales service
centre for Würth 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 oper-
ator. 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.
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 dam-
age 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
max
depends on the strength properties of the material 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
(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
max
to be cut.
The cutter clearance
a
should be
10 % of the sheet thickness d
max
(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 mate-
rials, 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. Retighten the
fastening screw
12
for the bottom cutter with a tight-
ening 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.
