Inflation can generate potential danger
situations. The operator has to carry out the
necessary precautions in order to guarantee
operational safety.
!Safety device:
To protect the operator from eventual dangers that
can occur during tire inflating on the locking plate,
the TCE 4225 has been equipped with a valve that
limits operational pressure to 3,5 bar.
5.3.1 Inflation with inflation pipe
1. Screw the valve element.

3. Operate on the inflation pedal to inflate the tire until
it reaches the nominal pressure.
5.3.2 Inflation with tubeless pneumatics devices
1. Insert the inflation pipe in the tire valve.
2. Lift the tire upwards with both hands, allowing the
air (that comes out from the holes in the jaw) to
come in between rim and tire.
3. Press the inflation pedal until end stop, to let the
air come out from the jaws and, in the meantime,
release the tire to allow bead seating.
!If the tire bead doesn't "seat" repeat accurately the
above mentioned operations.
4. Once the tire bead is seated, carry on the inflation
operation by holding the inflation pedal pressed in
