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.
