18 User’s manual - TECO 28 special
• Tool positioning (g.14 - 15)
- Set the mounting bar in work position and let the
mounting head touch the edge of the rim.
- Adjust the position of the operating arm by
turning the handwheel on the pole unit the tool
has moved 2 to 3 mm away from the edge of the
rim.
- Pull the lever placed on the horizontal arm until
the mounting bar is locked; the mounting head
will automatically move 2/3 mm. away from the
edge of the rim, thus protecting it from damage.
DEMOUNTING
- Position the tyre lever between the mounting
head and the tyre bead and lift the bead above the forward portion of the mounting head itself.
- Make the turntable rotate clockwise by pressing the relevant pedal lightly and repeatedly, then
keep the pedal continuously pressed.
- Rotate the wheel through one turn and at the same time press down with a hand on the side of
the tyre opposite to the mounting head, in order to position the bead in the central groove of the
rim.
- If the wheel has an inner tube, remove it after swinging the horizontal arm + mounting bar in
non-work position.
- Repeat the above described procedures to take out the second bead. Then move the horizontal
arm + mounting bar in non-work position and take the tyre off the rim.
