USING RUBBER CRAWLER
Rubber crawlers are designed to allow the machine to
travel without damaging road surfaces such as paved
road surfaces. Avoid damage to the rubber crawlers by
following the precautions below:
Forbidden Operations
1. Do not operate or steer the machine on or near
river-terrace, boulder and boulder mixed ground,
crushed-stone ground, uneven hardpan surfaces,
stumps, reinforcing bars, scraps, and steel plate
edges. Failure to do so may shorten the service life of
the rubber crawlers to a great extent.
2. Do not leave engine oil, fuel, and other kinds of
lubricants remaining on the rubber crawlers, and
avoid traveling on road surface covered with oil to
reduce the danger of sliding.
3. Do not travel the machine while raising one side
crawler off the ground with the front attachment.
Shear or damage to the rubber crawler may result.
Precautions for Using Rubber Crawlers
WARNING: The rubber crawler machine is less
stable than the steel crawler machine, as the edge
of the rubber crawler is easier to deform more
than steel crawler. Pay attention when operating
the machine at an angle to the tracks.
1. Do not store the rubber crawlers in a place where
they will be exposed to direct sunlight for a period of
more than three months.
2. Avoid unnecessary steering operations on concrete
roads, possibly resulting in premature wear of shoe
lugs and core metals. Also, avoid operating the
machine on high temperature [over 60°C (140°F)]
road surfaces during asphalt pavement work, possibly
causing premature wear of the rubber crawlers as
well as damage to the road surface.
