Proper use
The TRUMPF Nibbler N500-5 is a portable pneumatic
tool used to
• part plate-shaped workpieces made of material
such as steel, aluminium, plastic, etc.
• cut tubes and work sheets with bent profiles or
bent sheets, e.g. tanks, crash barriers, troughs,
etc.
• to nibble straight or curved outer edges and inside
cutouts
• to nibble according to a scribed line or template
• to nibble using a circular or straight line, slot
(optional)
Nibbling produces undistorted cutting edges.

Safety instructions
Hazardless working with this unit is only
feasible if you read the operating manual and
safety instructions (red print with the TRUMPF
identity number 125699) completely and follow
the instructions included therein.
Danger of injury
Check the unit, compressed air tube and
reception coupling before each use.
Have all damaged parts repaired by an
expert.
Danger of injury
Hot chips are ejected from the chip ejector at
extremely high speeds. You should therefore
use a chip bag to collect the ejected chips.
Danger of injury
The machine is supported by the workpiece
as long as they are in contact when the
cutting arrangement is "normal" (workpiece is
horizontal). Remember that the entire weight
of the machine must be supported as soon
as the workpiece is cut, as the machine no
longer has contact to the workpiece. (aid:
hook with balancer or retaining rope).
Always wear safety glasses, ear
protection, protective gloves and
proper footwear when working with
the machine.
• Do not connect the compressed air unless the
machine is turned off.
• Always disconnect the compressed-air tube from
the machine before beginning any work on the
machine!
• Always guide the compressed-air tube back away
from the unit.
• Use only original TRUMPF accessories.
Before initial use
1. Read the chapter on Safety.
Safety instructions
2. Mount the handle (the handle is enclosed
separately with the new machine).
3. Check whether the installed die is suitable for
the sheet thickness that is to be machined.
Die selection
4. Sharpen or replace blunt tools.
Resharpening tools
5. The flow pressure of the compressed air
must be 6 bar at the point of extraction.
6. Oil lubrication must take place for the
compressed-air motor.
Maintenance
E302en1_2.doc N 500 - 5 GB 3
Operating instructions
Check the tools for wear and the oil lubrication of the
compressed-air motor every hour.
Damage to property
Never work with blunt tools!
(The compressed-air motor may stop.)
Turning the unit on and off
Fig. 10332
Turning on the unit:
Press pushbutton 1 (releases compressed-air). Shift
lever 2 (= motor ON). The motor runs as long as the
lever is pressed. Pushbutton 1 can be released.
Turning off the unit:
Release lever 2 (the lever springs back into intial
position and the flow of compressed air is interrupted).
Damage to property
Do not begin machining the workpiece until
after the machine has been turned on and
has reached maximum speed!
The machine must never be turned off while
the punch is in the workpiece when the
cutting tracks end in the workpiece. In this
case, guide the machine back along the
freshly cut track a few millimeters before
turning it off.
Cooling and lubrication
The cutting results are improved and the service life of
the punch is increased if
• before machining the workpiece
the cutting track is coated with oil.
Recommended for steel:
Punching and nibbling oil, order no. 103387
Recommended for aluminium:
Wisura oil, order no. 125874
Changing the cutting direction Fig. 9912
The tool (i.e. the cutting direction) can be turned 90°
to the left or right if necessary, e.g. if space is
restricted.
• Loosen the locking lever (15).
• Turn the die carrier (1) 90° in the desired
direction.
• Close the locking lever (15).
Nibbling with a template
• The template should be at least 5 mm thick.
• The contour of the template should be 8.5 mm
away from the contour that is to be nibbled.
• The nibbler must be guided in such a way that the
outside edge of the punch guide always rests
against the template.
• Ensure that the radius is at least 90 mm!
Inner cutouts
Inner cutouts require a starting hole with a diameter of
at least 41 mm ∅.

Using the highest possible die
Distance between the die and the punch guide Fig. 19883
Extreme up and down movements (wobbling) may
occur during the cutting process if an incorrect die is
used.
Result: • excessive tool wear
• increased load on the machine
Remedy:
•
use the highest die whenever
possible
•
ensure that the distance X
between the sheet surface and
the punch guide (2) is as small
as possible

Punch
The stamp may be sharpened according to the table
below depending on the die used.
• Sharpen the front surface and provide proper
cooling.
• Touch up the cutting edge with a fine oil stone.

Damage to property
Lubrication of the compressed-air motor
is very important. The motor will fail if it is
operated without lubrication even for a
short time.
Install oil lubricating device in the compressed-air
line (e.g. Atlas Copco DIM 25).
Checking the oil supply of the motor
Hold a piece of paper in front of the exhaust opening
in the motor housing while the machine is running.
The oil supply is sufficient if oil stains form.
Recommended oils (compressed-air motor lubri-
cation):
• BP Energol RD 80 (-15 to +10 °C),
• BP Energol RD-E80 (+10 to +30 °C),
• Shell Tellus Oil 15 (-15 to +10 °C),
• Torculla 33 (+10 to +30 °C).
Cleaning
Clean the filter screwed into the connecting piece
(328) every 10 operating hours in order to prevent
throttling or power loss. (Unscrew, blow out with
compressed air and retighten.)
See the spare parts list for a diagram of items
328 (= "connection") and 329 (= "nipple").
Changing vanes
The performance of the machine decreases if the
vanes are excessively worn.
Vane replacement and all other repair work is to be
carried out by an expert!
Vane set (set of 4) on the rotor of the com-
pressed-air motor. See Item 305 in the spare
parts list for corresponding diagram.
Repairs
Danger of injury
Pneumatic tools comply with the relevant
safety regulations. Repairs may only be
carried out by qualified electricians in order to
prevent unnecessary accidents.
If the machine has been disassembled,
ensure that the shaft (11) is tightened with a
tightening torque of 25 Nm when
reassembling the unit.
