The abrasions, tears, cuts on the external surface of the track (
that in contact with the
ground
) are in most cases due to contact with sharp stones or cutting materials (
plating,
glass, nails, tile chips
) which cause cuts and complete or partial shredding of parts of the
track.
It is evident that due to the properties of the rubber this is inevitable, even if it depends on
the specific use and on the service conditions.
NB: The integrity of the rubber track and its faster or slower wear mainly depend on how it
is used and the way the machine is operated.

Periodically check tightness of the main parts of the machine:
-
Drive transmission
-
Quick fitting
- Engine fixing supports
- Operator cabin
- Arms and shovel caster retainer
N.B.: The resistance class of the nuts and bolts not specifically indicated is 8.8
To facilitate the fastening operations, the table on the side lists the driving torques according to
the relevant dimension and class of resistance.
