NOTICE
q
When using the breaker, if the lock pin is set to position (c) and the pedal is depressed in direction (D),
it will cause damage or defective operation of the breaker. To prevent it, when using the breaker,
always set the lock pin to position (b).
q
Before changing the position of the lock pin, stop the engine.
ADDITIONAL FILTER FOR BREAKER
ADDITIONAL FILTER FOR BREAKER:PC220-LGC5-043K00A
This filter (5) prevents deterioration of the hydraulic oil when
using a breaker.
Oil flows only when B mode is selected on the monitor.
NOTICE
Machines are equipped with additional filter (5) as stand-
ard when they are shipped from the factory.
ACCUMULATOR
ACCUMULATOR:PC220-LG25-043K00A

WARNING
The accumulator is charged with high-pressure nitrogen gas, so wrong handling may cause an explosion,
which will lead to serious personal injury or damage. When handling the accumulator, always observe the
following.
q
The pressure in the hydraulic circuit cannot be completely removed. When removing the hydraulic
equipment, do not stand in the direction in which the oil spurts out when carrying out the work. In
addition, loosen the bolts slowly when carrying out the work.
q
Do not disassemble the accumulator.
q
Do not bring it near flame or dispose of it in fire.
q
Do not make holes in it or weld it.
q
Do not hit it, roll it, or subject it to any impact.
q
When disposing of the accumulator, the gas must be released. Ask your Komatsu distributor to have
this work carried out.
These accumulators (6) are installed to reduce the peak pres-
sure in the hydraulic circuit when the breaker is being used.Do
not touch them usually.
NOTICE
On the 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, contact your
Komatsu distributor.
If the pressure of the nitrogen gas charging the accumulator drops, it will be impossible to release the
remaining pressure in the control circuit after the engine has stopped. In addition, if operations are con-
tinued with the nitrogen gas at low pressure, it will cause damage to the hydraulic circuit or machine.
Check the nitrogen charge pressure periodically.
See "CHECK CHARGE PRESSURE OF NITROGEN GAS IN ACCUMULATOR (FOR CONTROL CIRCUIT) (4-
67)".
