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 doted line) on its roller tread. During operation of a
new machine, or immediately after the rubber crawl-
ers 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 au-
thorized dealer.
