2.1 Correct use
Warning
Risk of injury!
¾For processing and materials, only use machines which are
named in "Correct use".
The TRUMPF Fold closer 300-2 is an electric hand tool used for
the following applications:
•Closing of Pittsburgh lock joints on correspondingly pre-
machined workpieces, e.g. ventilation ducts, housings,
containers, etc.
•Machining of all lock seam elevations.
Notes
•The lock seam can be closed on straight or curved contours.
•The machine adjusts itself automatically to the sheet thickness
to be processed.

3.1 Setting the tool
The clearance between the rollers and the guide rails can be
locked into place in order to be able to place the machine at the
desired position of the channel (and) to be able to remove it from
the machining position at the end of the channel:
•Adjustment lever (1) in position against the direction of feed:
Tool open.
•Adjustment lever (1) in end position in direction of feed:
•Tool in work position.

4. Operation
Caution
Damage to property possible due to too-high network
voltage!
Damage to the motor.
¾Check the power supply. The power supply must correspond
to the information on the machine type plate.
Warning
Danger of injury possible due to improper handling!
¾When working with the machine, always ensure that it has a
secure base.
¾Never touch the tool while the machine is running.
¾Always guide the machine away from the body while working.
¾Do not work holding the machine above your head.
4.1 Working with the F 300-2
¾Move the On/Off switch downwards.
In order to improve work results, lightly oil the rollers or the sheet
with universal oil (Order No. 138648).
Depending on the construction type of the channel to be machined,
a distinction is made between 2 possible ways of commencing
work:
•Channel open.
•Flange at the beginning of the channel.

V
V Advance direction 1 Lever
1. Move lever (1) in direction of feed in end position (tool in work
position).
2. Switch on machine and place against the beginning of the
channel.
–The curved guide rail ensures a simple placement of the
machine at the beginning of the machining process.
3. The machine is drawn through the driving rollers in the feed
direction, meaning that lock seam closure takes place.

1. Move lever (1) into position against the direction of feed (Tool
open).
2. Set machine up against desired (prepared) position on the
channel.
3. Position lever (1) in direction of feed. (Tool in work position).
–The working direction (direction of feed) of the machine is
determined by its design.
4. Switch on the machine.
5. Close the lock seam.
6. Move lever (1) into tool open position.
7. Switch off machine and remove from the machining position.

16 Operation E517EN_03.DOC
Notes
•A minor refinishing operation (length approximately 130 mm)
must be carried out manually at the end of the channel
following the use of the lock seam closer.
•For small sheet thicknesses (0.75-1 mm), the suspension lug
can be pre-formed by 30° without a moulding to a length of
approximately 80 mm.
¾Move the On/Off switch upwards. Switching off
