2.1 Intended use
Warning
Can cause injury or damage to health.
Only use the machine for work and materials described in
"Intended use".
Do not process materials containing asbestos.
The TRUMPF jointing press TruTool TF 350 is an electric hand tool
used for the following applications:
•Connecting sheet metal parts in overlapping alignment by
means of a cold forming process.
•This process involved with this mechanical sheet joining
technique is the "displacement jointing" (DIN 8593)
manufacturing method.
•The joint arises during an uninterrupted ram stroke.
•A movable punch and a fixed die together make up the set of
tools for this "one-step displacement jointing".
•The die consists of the fixed anvil, on which two lateral spring-
loaded non-rigid cutting segments are aligned.
•A positive locking connection is created by this process
(without additional connection elements such as screws or
rivets), by means of a combined forming and shearing
sequence with a subsequent cold extrusion procedure.
•Jointing of both uncoated and coated workpieces.
•Jointing without application of heat.
•No zinc vapors with galvanized sheets.
•Jointing of parts made of different sheet materials is possible.
•Jointing of two or three workpieces is possible.
•No preliminary roughing or finishing.
•Work also possible in upside-down position.
Cross-section of the joint
The CLi recharger charges exchangeable batteries of the Li-Ion
Energy 28 V system.

3. Setting work
3.1 Selecting the tool
The TruTool TF 350 jointing press can be equipped with tools in
various ways depending on the particular application.
Five different types of dies are available to make it possible to
utilize tools corresponding to different types of materials and
material thicknesses.
A special tool holder belongs with each type of die (= fixed arm or
tilting arm), which is used as a receptacle for the die.
The following example help for the selection of the tools.

3.2 Selecting tools for ventilation duct
construction
Whether or not the joint faces inwards (optical reasons) or
outwards (fluidic reasons) depends on the respective tool set
selected for application.
The "Plate for channel" makes it possible to have the jointing on
the flange profiles. When doing this, joints are possible in the
depressions of the flange profiles.
Note
The joints with "Plate for channel" are only possible in the
longitudinal direction.
The "Stripper for channel" makes working across the corners
easier.

3.3 Loading the rechargeable battery
Danger
Risk of fatal injury from electric shock.
Line voltage is present at the battery terminals.
Do not touch the electrical contacts (battery terminals) on the
recharger.
The rechargeable battery is partially charged (50%) at the time the
rechargeable battery electric tool is delivered.
Prerequisites
•The electric tool has been switched off for at least 1 minute.
Press the key on the rechargeable battery.
The LEDs on the rechargeable battery show the charging status.
Check charging status on the rechargeable battery
Checking loading status
Fig. 53299

E623EN_01.DOC Setting work 15
Before using the cordless electric tool, a new exchangeable battery
or one that has not been used for a long time needs to be charged.
Note
The full capacity is reached after 2-10 charging cycles.
Insert the exchangeable battery into the insertion well on the
recharger.
The loading time is between 1 min and 60 min, depending on how
far the rechargeable battery had been discharged beforehand. The
rechargeable battery is completely charged after 60 min.
The maximum charging current flows when the temperature of the
rechargeable battery is between 0° and 66°C. If a rechargeable
battery is inserted into the recharger that is too cold or too warm
(red LED flashes), then the charging process will begin
automatically as soon as the rechargeable battery has reached the
correct charging temperature (–10°C to +66°C).

Warning
Risk of injury due to improper handling.
Make sure the machine is always in a stable position when
operating it.
Wear safety glasses, hearing protection, protective gloves
and work shoes when working at the machine.
Never touch the tool while the machine is running.
Always operate the machine away from your body.
Warning
Damage to property due to improper handling.
Machine will be damaged.
Before joining, stand the swivel arm up vertically.
Align the punch and die the same (both lengthwise or both
crosswise).
The motor shuts off with excess load.
Allow the machine to run in idle until it has cooled down.
The machine can be operated again normally after it has cooled
down.
Note
Coat the seam point with oil before machining steel, chromium
steel, and aluminum or aluminum alloys. In this way:
•The joining quality is improved.
•The service life of the punch is increased.

Caution
Damage to property possible as a result of unnecessarily
long engine running times.
Switch the machine off once the processing of the workpiece
has been completed.
Before using the cordless electric tool, a new exchangeable battery
or one that has not been used for a long time needs to be
activated.
Place rechargeable battery briefly on the recharger or charge it
completely.
The LED on the rechargeable battery shows the charging status.
Note
The performance capacity of the rechargeable battery is available
