AVOID STRIKING WITH BUCKET
WARNING: The bucket bottom is curved.
Therefore, hammering or piling work with the
bucket is very hazardous. In addition, damage to
the bucket and the front attachment parts may
result.
Hammering or piling work with the bucket may create
hazardous situations. Never attempt to perform hammering
or piling work with the bucket. Damage to the bucket and
the front attachment parts may also result.
AVOID EXCAVATION USING
UPPERSTRUCTURE AND/OR BOOM SWING
POWER
Never attempt to move rocks or excavate a cliff face by
hitting the bucket using upperstructure and/or boom swing
power. Damage to the front attachment, or shortening of
the service life of the swing systems may result.
USE CORRECT TRACK SHOE
Never use rubber crawlers or wide track shoes on rough
terrain with scattered rocks, gravel or boulders. Failure to
do so may cause breakages of rubber crawlers, shoe
bending, looseness of shoe bolts, or damage to track parts
such as track links, or rollers. (Refer to the table for Types
and Applications of Track Shoes in the specification section.
Soil may easily become packed into the crawler during
travel operation on sandy ground. If the machine is driven
without removing the packed soil from the crawlers, the
rubber crawlers will be overloaded, possibly resulting in
breakage of the crawlers. Avoid causing the crawlers to
become packed with soil by removing soil as often as
possible.
