Trumpf F 125-3 is a pneumatic hand machine for finishing offset standing seams and angled standing seams on properly premachined workpieces, e.g. ducts, housings, containers, etc. The seam can be locked onto straight or curved contours, and in corners and angles. It can also be used for compressing metal edges for rubber, textile or plastic workpieces. The machine has a maximum sheet thickness of 1.25 mm, a maximum seam thickness of 5 mm, a working speed of 5-6 m/min, and a weight of 2.2 kg. It requires an operating pressure (flow pressure) of 6 bar and an air consumption of 0.4 m³/min.

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.
• 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. The flow pressure of the compressed air
must be 6 bar at the point of extraction.
3. Oil lubrication must take place for the com-
pressed-air motor.
Maintenance
Operating instructions
Damage to property
Check the oil lubrication of the compressed-
air motor every hour.
Turning the unit on and off
Fig. 11417
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 com-
pressed air is interrupted).
Damage to property
Be careful that the machine should firstly be
fed to the workpiece when it is switched on
and full speed has been reached!
If you notice that the seam can no longer be properly
sealed, especially with thin plates, the cause could be
a worn plastic buffer. In this case, a new plastic buffer
must be installed.
Refer to the spare parts list for plastic buffer
(41).

Hammer adjustment
The distance between the upper and lower hammer
must be set according to plate thickness or seam
thickness.
Refer to figs. 11400 and 11401
Hammer adjustment for standing seam
a) Release the small fastening screw (46).
b) With the motor running, set the hammer opening
to the desired seam thickness using the knurled
nut (43).
c) Arrest the small knurled screw (46).
d) Fold the seam.
Hammer adjustment for angled standing seams
a) Release the small knurled screw (46).
b) Set the maximum hammer opening with the large
knurled nut (43).
c) Arrest the small knurled screw (46).
d) Prefold the seam.
e) Release the small knurled screw (46) again.
f) With the motor running, set the hammer opening
to the desired seam thickness using the large
knurled nut (43).
g) Arrest the small knurled screw (46).
h) Fold the seam.
Overload protection
Minor variations in the seam thickness are
compensated for by the plastic buffer.

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
lubrication):
• 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 (set of 4) on the rotor of the
compressed-air motor. See Item 315 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.
Use only o r i g i n a l s p a r e p a r t s.
Please note the specifications on the output plate.
