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 the 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.
Avoid Moving Objects with Breaker.
Do not use the breaker and/or the bracket to move objects.
Damage to the boom, arm, and/or breaker may result.
Do not use the breaker and/or the swing function to move
objects. Damage to the boom, arm, and/or breaker may
result.
Avoid Operating Breaker at Cylinder Stroke End
Always operate the breaker by positioning the cylinder rods
100 mm or longer before the stroke end position.
When operating the breaker with cylinders fully retracted
or extended, hydraulic cylinders, arm or boom may be
damaged.
