Accumulator
The pilot control system is equipped with an accumulator. For a
short period of time after engine has been stopped, accumulator
will store a pressure charge that allow hydraulic controls to be
activated. Activation of any controls will allow selected functions
to operate under force of gravity.
When performing maintenance on pilot control system, release
hydraulic pressure in system as described in "Handling of
Accumulator" on page 4-97.
The accumulator is charged with high-pressure nitrogen gas. If it
is improperly handled it can explode causing death or serious
injury. Always observe the following precautions:
•
Do not drill or punch holes in accumulator or expose it to
any flames, fire or external heat source.
•
Do not weld on accumulator.
•
When performing disassembly or maintenance of
accumulator, or when disposing of accumulator, charged
nitrogen gas must be properly released. Contact your
DOOSAN distributor for assistance.
•
Wear safety goggles and leather gloves when working on
an accumulator. Hydraulic oil under pressure can
penetrate skin and result in death or serious injury. If fluid
enters skin or eyes, get immediate medical attention from a
physician familiar with this injury.
Compressed Air
•
When cleaning filters, radiator or other components with
compressed air, there is a hazard of flying particles that
can result in serious injury.
•
Always wear safety goggles, dust mask, leather gloves,
and other protective devices.
