Safety Warnings for Nibblers
 The power tool is not suitable for stationary operation.
For example, it may not be clamped in a vice or fastened on
a workbench.
 Wear protective gloves while working and pay particu-
lar attention to the mains cable. Sharp burrs develop at
the cut steel sheet and can cause injuries to the operator or
damage the mains cable.
 Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
 Products sold in GB only: Your product is fitted with a
BS 1363/A approved electric plug with internal fuse
(ASTA approved to BS 1362).
If the plug is not suitable for your socket outlets, it should
be cut off and an appropriate plug fitted in its place by an
authorised customer service agent. The replacement plug
should have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible
shock hazard and should never be inserted into a mains
socket elsewhere.
Products sold in AUS and NZ only: Use a residual current
device (RCD) with a rated residual current of 30 mA or
less.

The values given are valid for a nominal voltage [U] of 230 V. For differ-
ent voltages and models for specific countries, these values can vary.
Operation
Starting Operation
 Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Switching On and Off
To start the machine, push the On/Off switch 1 forward so
that the "I" is indicated on the switch.
To switch off the machine, push the On/Off switch 1 toward
the rear so that the "0" is indicated on the switch.
Locking/Loosening the Die
For straight cuts, tighten the locking screw 3 using an hex key
(size 2.5 mm) in order to lock the die 4.
For curved cuts, loosen the locking screw 3. The die 4 can
move freely now and adjusts to the direction of the feed
strength.
Working Advice
 Before any work on the machine itself, pull the mains
plug.
 Wear protective gloves while working and pay particu-
lar attention to the mains cable. Sharp burrs develop at
the cut steel sheet and can cause injuries to the operator or
damage the mains cable.
 Exercise caution when handling the cutting chips. The
chips have sharp tips that can cause injuries.
Apply the machine to the workpiece only when switched on.
Always hold the machine vertical to the surface of the steel
sheet and do not tilt it.
The cut takes place during the upward motion of the punch.
Guide the machine evenly and with moderate feed in the cut-
ting direction. A too high feed rate significantly reduces the
service life of the cutting tools and can damage the machine.
