worn, however, if it is excessively worn, the
rubber track shoe is likely to be slippery and
more travel force is required. If the remaining
lug is less than 5 mm high, replace it with
brand-new one.
2. Exposure of Steel Cords
If steel cord is exposed because of weary
rubber or damage, replace it with brand-new
one.
3. Break of Steel Cords
When break of steel cord is detected, replace
it immediately. If you leave it as it is, the rubber
track shoe can be break without expectation,
which causes a serious accident.
4. Crack of Covering Rubber
If a crack is 30 mm or more long and 8 mm or
more deep, repair the cover immediately. if
Steel cord appears even if a crack is small,
repair it immediately.

rusts steel cords and break the rubber track
