OPERATION
CAUTIONS
Observe the following cautions when
operating the machine:
HANDLING RUBBER CRAWLERS
• Do not turn the undercarriage with the front
of the machine body lifted using the hoe
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.
• 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
gets on the crawler belts, wash if 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 on snowy or frozen
surfaces in winter, as the crawler belts tend
to slip in such conditions.
• 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 (three 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 lugs are
made of rubber. Be very careful when
slewing and swinging sideways.
PREVENTING THE RUBBER CRAWLERS
FROM COMING OFF
Observe the following cautions to prevent
the crawler from coming off:
• Always keep the crawlers at the proper
tension.
• When traveling over a large step such as a
cobblestone or rock (20 cm (8 in.) or
deeper), climb up the step at the right
angle and do not change courses on top of
the step.
