2.1 Intended use
Warning
Risk of injury.
¾Only use the machine for the work and materials described
under "Intended use".
The TRUMPF Nibbler N 700 is a hand-held device powered by
compressed air used for the following applications:
•Slitting plate-shaped workpieces made of a punchable material
such as steel, aluminum, non-ferrous heavy metals and plastic.
•Slitting tubes and processing edged sheet profiles and press
brake bendings, e.g. for tanks, crash barriers, troughs, etc.
•Nibbling straight or curved exterior and interior cutouts.
•Nibbling along scribed lines or templates.
Note
The nibbling process produces cutting edges free of deformations.

3.1 Choosing a dieen
One of 3 types of dies can be selected for the machining process
according to material thickness, tensile strength and type of
workpiece.
Make sure that the clearance (X) is as small as possible so that the
machine is well clamped and does not hammer.

This is caused by using an unsuitable die, and can result in
excessive tool wear and increase the load on the machine.

E Penetration depth
Penetration depth of the punch
The penetration depth of the punch into the die should be 1 to
3 mm.
1. Rotate the eccentric shaft (21) until the punch (9) has reached
its maximum penetration depth.
2. Loosen the clamping screw (36).
3. Rotate the die carrier (7) by 360° as often as needed until the
punch penetration depth of 1-3 mm has been achieved. One
rotation (360°) corresponds to a height adjustment of 1.75 mm.
4. Tighten clamping screw (36).

4.1 Working with TruTool N 700
Warning
Risk of injury due to improper handling.
¾Make sure the machine is always in a stable position when
operating it.
¾Never touch the tool while the machine is running.
¾Always operate the machine away from your body.
¾Do not operate the machine above your head.
1 Bracket 2 Lever
1. Push the bracket (1) forwards.
2. Push the lever (2) against the motor housing.
1. Do not move the machine towards the workpiece until full
speed has been reached.
2. Machine the material.
–Machine the desired nibbling line
3. If the cutting track accidentally runs into the sheet, keep the
machine running and pull it a few millimeters back towards
where the cutting track has already been cut open.
4. Switch off the machine.
Note
The cutting result is improved and the service life of the punch
increased if the cutting track is coated with oil before machining the
workpiece.

¾Release the lever (2).
The lever springs back to the initial position and the compressed
air is interrupted.
4.2 Changing the cutting direction
In situations where space is limited, the tool can be mounted so it
has a different cutting direction:
•Mount the tool at an angle of 90° to the right or to the left
(cutting profiles).
•Mount the tool at a 180° rotation (nibbling backwards).
1. Loosen clamping screw (36).
2. Turn the die carrier (7) in the desired direction.
3. Retighten the clamping screw (36).
4.3 Nibbling with templates
The following requirements must be met when nibbling with tem-
plates:
•The template must be at least 5 mm thick.
•There must be a clearance of 11 mm between the contour of
the template and the contour to be nibbled out.
•Guide the nibbler so that the exterior cutout of the punch guide
(5) rests against the template for the enitirety of the nibbling
process.
•Observe a minimum radius of 135 mm.
4.4 Making interior cutouts
Interior cutouts require a start hole at least 60 mm in diameter.

5. Maintenance
Warning
Risk of injury due to uncontrolled machine movements.
¾Remove the compressed air hose when changing tools and
before performing any maintenance work on the machine.
Warning
Risk of injury due to repair work not being carried out
properly.
Machine does not work properly.
¾Repair work may only be carried out by a qualified technician.
Caution
Damage to property caused by blunt tools.
Machine overload.
¾Check the cutting edge of the punch for wear every hour.

There are two ways of lubricating the compressed-air motor:
1. For short operating times or if frequently changing the
operation site, use the internal oil chamber.
–Before start-up, always check whether the oil chamber is
filled to the top (see Fig. 10776, p. 19).
–Refill the oil via the screw plug opening (313) once every
operating hour.
Notes
The oil level in the machine must not exceed the maximum
height (max.).
If the oil level exceeds this height, oil will overflow from the
vent in the motor housing.
2. For long periods of use, install an oil mist lubrication device
in the compressed air line (e. g. Atlas Copco DIM 25).

¾Lubricate the speed limiter (324) and ball bearings with
lubricating grease during the regular maintenance of the
machine (see replacement parts list).
Note
Handle the speed limiter (324) especially carefully, as damage can
lead to excessive rotation speed.
¾Relubricate the ball bearings in the motor flange via the grease
nipple (312) every 10 operating hours using a grease gun (see
Fig. 10776, p. 19).
Recommended lubricant:
•BP Energol RD 80 (-15° to +10 °C/+5° to +50°F).
•BP Energol RD-E80 (+10° to +30 °C/+50° to +86°F).
•Shell Tellus Oil 15 (-15° to +10 °C/+5° to +50°F).
•Torculla 33 (+10° to +30 °C/+50° to +86°F).
5.5 Replacing fins
Worn fins decrease machine power.
¾Have the fin set checked and replaced as needed by a
qualified technician.
Note
Only use original replacement parts and observe the information
on the rating plate.
5.6 Cleaning the filter
In order to avoid reduction in speed and power:
¾Clean the filter (355) every 10 operating hours (see Fig. 10776,
p. 19).
