Bead damage caused by fitting machine
Bead damage caused by fitting machine
The following errors which can be made when fitting tyres can lead to severe tyre damage:
t  When rolling the upper bead on the tyre fitting machine, the opposite tyre bead is not seated completely in the rim well.
t  The fitting head was not adjusted correctly.
t  The edge of the fitting roller rolls onto the bead.
t  The guide rollers are worn or have sharp edges.
It is often possible to identify the tracks of the guide roller as it was applied or ran off where the damage occurred.
  Note
Both tyre beads as well as the bead seats must always be coated with assembly paste.
If fitting damage remains undetected, there is a danger that the tyre will fail later during operation.
THEREFORE PLEASE NOTE:
l  Never fit a tyre without using assembly paste.
l  Do not allow the bead seating pressure to exceed 3 bar.
l  Do not allow the tyre inflation pressure to exceed 4 bar.
l  When the tyre has been fitted, reduce the tyre pressure to the specified value.
