attachment (the upperstructure is not
turned). Doing so will twist the crawlers
with the load concentrated on a single
point on the crawler belt, causing rapid
damage to the crawlers.
•Avoidchangingcourseabruptlyorspin-
turning on concrete surfaces whenever
possible. Doing so may wear or damage
the rubber crawlers.

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
gets on the crawler belts, wash if off
thoroughly with water.

hitting the bucket against them.

surfaces in winter, as the crawler belts tend
to slip in such conditions.

between –25°C to +55°C (–14°F to 131°F).

storingtherubbercrawlersforlong
periods of time (three months or more), do
so indoors in a place not exposed to direct
sunlight or rain.
