Designated use
The TRUMPF Nibbler N 200-5 is a pneumatic hand
tool used for:
•splitting plate-shaped workpieces made of a
punchable material such as steel, aluminum, non-
ferrous heavy metals, and plastic;
•splitting tubes as well as machining sectional
sheets (damaged sheets);
•nibbling straight or curved exterior and interior
cutouts;
•nibbling from scribed lines or templates.
The nibbling process produces cutting edges free of
deformations.
Because of the hollow round punch, the nibbler can
be rotated at any position such that processing can
continue in any direction.

For your safety
Safe operation of the appliance is only
possible when the operator's manual and the
supplied safety information (red print,
TRUMPF order no. 125699) have been
completely read and the instructions
contained within have been strictly adhered
to.
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 swarf box to collect the ejected chips.
Always wear safety glasses, hearing
protection, protective gloves, and hard
shoes when operating.
•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 putting the machine into
service
1. Read the chapter on safety.
For your safety
2. Replace blunt tools.
Tool changes
3. The flow pressure of the compressed air must be
6 bar at the point of extraction.
4. Oil lubrication must take place for the
compressed-air motor.
Maintenance
Operating istructions
Damage to the machine!
Check the tools for wear and the oil
lubrication of the compressed-air motor
every hour.
Never work with blunt tools!
(the compressed-air motor may stop).
Switching on and off
Fig. 26691
Turning on the unit:
•Press lever 1.
Turning off the unit:
•Release lever 1
(the lever springs back into initial position and the
flow of compressed air is interrupted).

E415EN1_2.DOC N 200-5 GB 3
Damage to the machine!
Do not begin machining the workpiece until
after the device has been switched on and
has reached maximum speed!
For cutting tracks which end in the work-
piece, the unit must never be turned off as
long as the punch is in contact with the
workpiece. In such cases, guide the device
back along the freshly cut track a few
millimeters before switching it off.
Cooling and lubrication
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.
Recommended for steel:
Punching and nibbling oil, order no. 103387
Recommended for aluminum:
Wisura oil, order no. 125874
Changing the cutting direction in 5° increments
For right/left-hand operation or if a sectional sheet is
to be machined, the tool and cutting direction can be
turned to the right or left.
Fig. 25666
•Push the sleeve (1) up until it stops.
•Turn the tool (2) to the desired direction.
•Release the sleeve (1) and turn the tool (2)
slightly such that it locks into the next index
position.
Interior cutouts
Interior cutouts require a start hole of at least 16 mm Ø.

Tool changes
Risk of injury!
Always disconnect the compressed-air
tube from the machine before beginning
any work on the machine!
If the punch or die becomes blunt, change the tool.
Removing the punch Fig. 25655
a) Pull grip (2) back.
b) Pull out tool (6) from housing (1).
c) Remove punch (5).
Mounting the punch Fig. 25655
Lightly lubricate punch (5) and boring in tool (6) with
lubricating grease "G1".
See "F" in Fig. 25655
•Insert punch (5) into slot on punch adapter (4) and
align cutting direction forward.
•Align cutting direction of tool (6) forward and insert
it into housing (1).
•Pushing back the grip (2) secures the tool in the
housing (6).
Changing the die Fig. 25655
•Push cover ring (7) upward out of slot.
•Push out cylindrical pin (9) using a drift punch.
•Pull off die (8) from the carrier pin and replace it
with a new die.

Compressed-air motor l u b r i c a t i o n
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 lubrica-
tion):
•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 327 every 10 operating hours in order
to prevent throttling or power loss.
See the spare parts list for a diagram of filter
327.
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 (4) on the rotor of the compressed-
air motor. See Item 315 in the spare parts list
for corresponding diagram.
Repairs
Risk of injury
Pneumatic tools must comply with the
relevant safety regulations. Repairs must
only be carried out by a qualified
professional; otherwise operational
accidents may occur.
Only use original spare parts.
Please note the specifications on the rating plate.
You will find a list of TRUMPF representatives
at the back of this operator's manual.
