Always check that the size of the tyre is compatible with the size of the wheel before
proceeding with mounting. NEVER attempt to mount tyres on rims where it is not
possible to identify the respective diameters precisely.
Clean the rim if necessary, and inspect it carefully for any damage or start of damage,
deformations or cracks.
If the tyre demounted previously is to be reused, make sure that it is free from cuts and tears
and that the cords of its carcase have not been laid bare.
These checks are very important to avoid risks of damage to the tyre during the bead
insertion and inflation stage.
Before you start with tyre mounting operations, apply a liberal amount of tyre manufacturer
approved rubber lubricant to both beads (Fig.18).
Lubricated beads require less force to mount/seat and are protected against torsional
damage.
IMPORTANT: use only special tyre lubricants approved by the tyre's manufacturer. Never use
hydrocarbon-based lubricants.
Make sure that the tyre is in good condition without any signs of undue wear or damage.
Place the tyre over the wheel and tilt the tower forward. Position the bottom bead (Fig.19)
beneath the right hand side of the mount/demount head.
Press the table top control pedal to turn the table clockwise and mount the bead. Use the
drop centre by pressing the sidewall opposite the head to reduce tensional force on the bead
as the wheel rotates (Fig.19).
During self-centering chuck rotation, keep your hands and other parts of your body well
away from the tool to avoid the risk of crushing.
Once you have mounted the bottom bead, repeat the same steps for the upper bead (Fig.20).
Tilt the tower back
Unclamp the wheel from the table top.
To facilitate mounting/demounting of low-profile tyres, it is advisable to use the bead presser
pliers (optional accessory) (Fig. 20a).
