Use Correct Track Shoe - Hitachi ZAXIS 30U-5N Operator's Manual

OPERATING THE MACHINE

Use Correct Track Shoe

Never use rubber crawlers or wide track shoes on rough terrain
with scattered rocks, gravel or boulders. Failure to do so may
cause breakages of rubber crawlers, shoe bending, looseness
of shoe bolts, or damage to shoe track parts such as track
links, or rollers. (Refer to the table for Types and Applications
in the specification chapter.) Soil may easily become packed
into the crawler during travel operation on sandy ground. If
the machine is driven without removing the packed soil from
the crawlers, the rubber crawlers will be overloaded, possibly
resulting in breakage of the crawlers. Avoid causing the
crawlers to become packed with soil by removing soil as often
as possible.
