Pay attention to the seams of the crawler
Rubber tracks have seams. When adjusting the
crawler, make sure the seam is in the upper
central position. If a machine has an upper

will not be obtained and the track will be too
slack, thus having to be adjusted again.
How to use rubber track skillfully
1. In the turn, please try to avoid turning in
place to slowly rotate the turn. This will reduce
track flange wear and rock entrapment.
2. When turning, do not forcibly turn the
overflow valve when the crawler card enters the
soil and sand. Receding in a straight line before
turning after sand removal.
3. Please never drive on river beach, gravel lot
and steel bar and iron scrap. Otherwise it will
damage the rubber part and shorten the service
life of the track.
