TECO 28 Special - Tyre Inflation Procedures

20 User’s manual - TECO 28 special
• Lower bead mounting
- Place the bottom bead of the tyre underneath the tool and at the same time apply a little pressure to
the tyre by hand while starting to rotate the wheel (pedal 1) for easier bead insertion.
- Rotate until tyre mounting is complete.
• Upper bead positioning (g. 19)
- Position the upper tyre bead.
Take care that the tyre does not slip underneath the tool.
• Upper bead mounting
- Rotate the wheel using pedal 5 to start mounting the upper bead. Press manually the tyre bead to
keep it inserted in the channel until the bead assembly is successfully completed.
- Return the tool into its rest position.
NOTE: for oversized (more than 19’’) or particularly tough wheels, it is recommended the use of the
pneumatic bead presser. In this case the following procedure must be applied:
• Tyre ination
- For ination, see “INFLATION” section.
• Tilt the tower backwards in non-work position.
• Free the wheel from the clamps and remove it from the tyre changer.
INFLATION
WARNING
Ination is well known to be a dangerous operation. It must be carried out in accordance with
the instructions below. Safety goggles with plain lenses and safety footwear must be worn.
CAUTION
During this operation, noise levels assessed at 85 dB(A) may occur. Operators are advised
to wear hearing protection devices.
DANGER
Although the machine limits the pressure, it does not provide sufcient protection if the tyre
bursts during ination.
Failure to comply with the instructions below will render tyre ination dangerous.
DANGER
NEVER exceed the pressure recommended by the tyre manufacturer. Tyres may burst if they
are inated beyond these limits or their structures may incur serious damage not visible at
the time. KEEP YOUR HANDS AND THE WHOLE BODY WELL AWAY FROM THE TYRE DURING
INFLATION. Make sure you are concentrated during this operation and check tyre pressure
continuously to avoid excess ination. A bursting tyre can cause serious injuries or even death.
- Release the wheel from the sliding clamps on the table top.
- Pull the horizontal arm all away out.

- Lock the horizontal and vertical arms in the positions described on Fig.2.4.
- Connect the Doyfe ination chuck (32) on the air hose to the valve stem.
- Inate the tyre by using the inaction gun
