3. Operating the machine with rubber crawlers sagging
on uneven surfaces can result in derailment of rubber
crawler, possibly causing the rubber crawlers to be
damaged.
4. When lowering the machine raised above the ground
using the front attachment, slowly lower the machine to
the ground.
5. The new rubber crawler has a thin rubber film (shown in
dotted line) on its roller tread. During operation of a new
machine, or immediately after the rubber crawlers are
replaced, the rubber film may come off due to contact
with the rollers. This is not abnormal. (See the right
illustration.)
6. If the rubber crawler is damaged and the rubber crawler
core wire rusts, the service lifetime of the rubber crawler
will become short. If damaged, the rubber crawler must
be repaired. Contact your authorized dealer.
