13-3-4 Life of the rubber crawler
Check the remaining life of the rubber crawler by the abrasion loss in the rubber crawler
height as shown in the figure below. Note that the life slightly differs depending on the
conditions of site and the operation of the machine.
PRECAUTIONS:
(1) Wipe immediately if fuel or hydraulic oil sticks to rubber crawler.
(2) Check that there are no sharp edges protruding on the ground.
(3) Avoid using on beach. (This may affect the adhesion of the core metal.)
(4) If the machine is going to be stored for a long time, never store it where it will be
directly exposed to sunlight.
