PRECAUTIONS FOR BREAKER OPERATION
WARNING: Machine stability is reduced as the breaker
is much heavier than the bucket.
When using a breaker, the machine is more apt to tip
over. Also, flying objects may hit the cab or other part
of the machine. Observe the following precautions
and take any other precautions necessary to prevent
accidents and machine damage from occurring.
• Avoid hitting objects with breaker.
The breaker is heavier than the bucket, causing the break-
er to lower faster.
Take care not to hit any objects with breaker. Doing so
will result in damage to the breaker, the front attach-
ment, and/or the upperstructure. Always move (lower)
the breaker slowly to position the tip of the chisel on the
object to be broken before starting breaker operation.
• Do not use the breaker and/or the swing function to
move objects. Damage to the boom, arm, and/or breaker
may result.
• To prevent cylinder/machine damage, do not operate the
breaker with the hydraulic cylinder rod fully retracted or
fully extended.
• Stop operation if breaker hydraulic hoses jump abnormal
-
ly. Change in breaker accumulator pressure or a damaged
accumulator will cause abnormal hose jumping and may
cause breaker and/or machine damage.
Immediately contact your authorized dealer if this hap-
pens.
