ATTACHMENTS AND OPTIONS
Accumulator
The accumulator is charged with high-pressure nitrogen gas, so mistaken operation may cause an explosion, which will lead to
serious injury or damage. When handling the accumulator, always do as follows.
The pressure in the hydraulic circuit cannot be completely removed. When removing the hydraulic equipment, do not stand
in the direction that the oil spurts out when carrying out the operation. In addition, loosen the bolts slowly when carrying out
the operation.
Do not disassemble the accumulator.
Do not bring it near flame or dispose of it in fire.
Do not make holes in it or weld it.
Do not hit it, roll it, or subject it to any impact.
When disposing of the accumulator, the gas must be released. Please contact your Komatsu distributor to have this work
carried out.
These accumulators (6) and (7) are installed to reduce the peak
pressure in the hydraulic circuit when the breaker is being used.
Normally, do not touch them.
NOTICE
On machines equipped with a breaker, it is necessary to install an accumulator to the breaker piping to match the model number
of the breaker manufacturer. If no accumulator is installed and the breaker is operated, the service life of the machine will be
reduced. For questions about the breaker, please contact your Komatsu distributor.
For details, see "CHECK NITROGEN GAS CHARGE PRESSURE IN ACCUMULATOR (for breaker) (PAGE 4-76)" or "CHECKING
CHARGE PRESSURE OF NITROGEN GAS IN ACCUMULATOR (FOR CONTROL CIRCUIT) (PAGE 4-79)".
