data of the tool.
▪ Always check the position of ON/OFF switch. The
power tool must be connected to the power supply
socket only when this switch is in OFF position. If the
plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, which could cause a serious
accident.
▪ Make sure the cord and the plug are in order. If the
replacement of the supply cord is necessary, this has
to be done by the manufacturer or his agent in order
to avoid a safety hazard.
SWITCHING ON - SWITCHING OFF
▪ Switching on - Push the ON/OFF switch (10) forward
to the gear case (7), until its front end will sag, thus
fixing itself (Fig.1a).
▪ Switching off - Press the back lifted end of the ON/
OFF switch (10) and release it to move back in its ini-
tial position (Fig.1b).
OPERATING THE NIBBLER
Mount the fixed and the auxiliary handles.
Fasten the material to be cut to the work table.
During operation hold the fixed handle with one hand,
and the auxiliary handle with the other hand.
Push the slider of the ON/OFF switch (10) forward to
switch the machine on.
WARNING: Never feed the nibbler into the
material being cut if the motor is not rotating.
Hold the tool vertically to the surface of the machined
material during operation. Tilting the machine in any di-
rection is not recommended and it shall decrease the ef-
ficiency, besides the die might be damaged.
To cut flat sheet position the cutting head as shown on
(Fig. 2).
For curve cutting with small arc radius, it is necessary to
rotate the machine gently in order to avoid bending and
deformation of the die.
To begin cutting in the centre of the material, first make
a round opening for the die to be inserted into (Fig. 3).
To cut corrugated material (BN 502), operate the die and
the punch as shown on (Fig. 4). Operation can be facili-
tated by rotating the die at 90o so that the carrier (12) is
parallel to the grooves in the corrugated sheet (Fig. 5).
Coat the cutting line with machine oil to increase the
punch and die service life and cutting speed.
To cut steel sheet, use machine oil, used for machining
metals.
To cut Aluminium and non-ferrous metals, use mixture of
naphtha and turpentine with 7:3 ratio.
Lubricate the die and punch with machine oil every 10
min of operation.
Excessive fast feeding of the nibbler shall result in con-
siderable overloading the die, punch and motor.
Quality cuts can be achieved until the punch cutting edge

is sharp enough. The worn punch shall be replaced with
a new one. Replace the worn die and punch in due time.
WARNING: The die and punch must not be
reground.
WARNING: Disengage the cutting head from
the material while the motor is still running. Otherwise
the punch may be damaged.
Always switch the machine off and wait until the punch
has come to a complete standstill before placing it down.
REPLACING THE DIE AND THE
PUNCH GUIDE
Using the 3mm hex key loosen the inner hex screws (4),
fixing the die (1) and the punch guide (3).
Clean the contact surfaces of the carrier (12).
Install the new die and the new punch guide.
Place the inner hex screws (4) back and tighten them us-
ing the 3mm hex key.
REPLACING THE PUNCH
Using the 3mm hex key loosen the two inner hex screws
(4), fixing the punch guide (3) and remove the guide.
Using the screw sleeve wrench unwind the screw sleeve
(6) and pull out the piston sleeve (5).
Release and take out the worn punch and replace it with
a new one.
Reassemble in reverse order.
ACCESSORIES
Fixed handle, auxiliary handle, 5 mm hex key, 3 mm hex
key, screw sleeve wrench, plastic case.

Maintenance

WARNING: Always ensure that the tool is
switched off and unplugged before attempting to
perform inspection or maintenance.
INSPECTIONS
Inspecting the die and punch
Longer service life and efficiency can be achieved using
only sharp die and punch.
Using worn-out die and punch significantly decreases
the machine performance capability and may result in
failure. When you ascertain signs of wearing replace the
die and punch immediately.
WARNING: The die and punch must not be
reground.
