PRECAUTIONS FOR BREAKER OPERATION
d
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
breaker to lower faster.
Take care not to hit any objects with breaker. Doing so
will result in damage to the breaker, the front attachment,
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
abnormally. 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
happens.
