For details of the path of the oil, see "HYDRAULIC CIRCUIT (PAGE 6-8)".
Consult the manufacturer of the breaker to decide if an accumulator for the breaker circuit should be installed on
your machine.
For other precautions when handling the breaker, follow the instruction manual from the breaker manufacturer
and use the breaker correctly.
The deterioration of the hydraulic oil when using the breaker is much faster than for normal operations, so reduce
the maintenance interval for the hydraulic oil and element.
