HANDLING OF ACCUMULATOR
Release pilot accumulator pressure using the following
procedure:
1.
Park machine on firm, level ground. Lower the front
attachment to the ground and shut down engine.
2.
Set safety lever on "RELEASED" position.
3.
Turn starter switch to the "I" (ON) position.
4.
Fully stroke work and travel levers in all directions.
5.
Set safety lever on "LOCK" position.
6.
Turn key to "O" (OFF) position and remove from starter
switch.
7.
Remove accumulator by unscrewing it slowly.
WARNING!
Even though the engine is stopped, the hydraulic
accumulators for the pilot system are still charged. Do
not disconnect any pilot system hoses until accumulator
pressure has been released from the circuit. To release
pressure, turn the starter switch to the "I" (ON) position
and operate all hydraulic control levers and forward/
reverse travel levers. Even though the engine is
shutdown hydraulic actuated components may move
while releasing pilot pressure. Keep all personnel away
from excavator while performing this operation.
•
Set safety lever on "LOCK" position after
stopping engine.
•
DO NOT mishandle accumulator (s). They are
very dangerous because they contain
high-pressure nitrogen gas.
•
DO NOT punch a hole or apply heat or fire to
an accumulator.
•
DO NOT weld on accumulator, or try attaching
anything to it.
•
When replacing an accumulator, contact a
DOOSAN
distributor or sales agency so the
gas can be properly released.
•
Wear safety goggles and protective gloves
when working on an accumulator. Hydraulic oil
under pressure can penetrate the skin and
cause serious injuries.
