OPERATION
Handling Rubber Crawlers
Cautions
Heed the following cautions when operating
the machine:
¡ Do not turn the undercarriage with the front
of the machine body lifted using the hoe
attachment and the upperstructure left in
this posture. Doing so will twist the crawler
with the load concentrated on a single
point on the crawler belt, rapidly leading
to damage.
¡ Avoid changing course abruptly and
spinning on concrete surfaces whenever
possible.
Doing so may wear or damage the rubber
crawlers.
¡ Avoid drops that may expose the rubber
crawlers to strong shocks.
¡ Salt, potassium chloride, ammonium
sulfate, potassium sulfate, and triple
superphosphate of lime can damage the
crawler belts. If any of these substances
should get on the crawler belts, wash them
off thoroughly with water.
¡ Do not let the sides of the rubber crawlers
rub against concrete or walls.
¡ Do not damage the rubber crawlers by
hitting the bucket against them.
¡ Be especially careful in the winter on
snowy or frozen surfaces as the crawler
belts tend to slip.
¡ Use rubber crawler belts at temperatures
between -25°C to +55°C (-14°F to 131°F).
¡ When storing the rubber crawlers for long
periods of time (3 months or more), do so
indoors in a place not exposed to direct
sunlight or rain.

¡Rubber crawler belts are not as stable as
steel crawler belts since the entire lug is
rubber. Be very careful when slewing and
swinging sideways.
Preventing the Rubber Crawlers from
Slipping Off
Heed the following in order to prevent the
rubber crawlers from slipping off:
¡ Always keep the crawlers at the proper
tension.
¡When traveling up large cobblestone or
rock steps (20 cm (8 in.) or greater), climb
up the step at a direct angle and do not
change course on top of the step.
