Check the pulleys for play, oil leakage, water leakage and drain hole clogging. If any fault is
found, request us or our sales agency for the dismounting and repair.
[2] REPLACING THE ACCUMULATOR
Replace the accumulator every 2 years or 4000 hours of service, whichever falls first.
Since the accumulator is charged with high pressure nitrogen gas, any incorrect
handling of it may cause an explosion and therefore cause a serious accident. Strictly
observe the following for handling:
• The pressure in the hydraulic circuit cannot be totally relieved.
hydraulic unit, stay away from the escaping oil direction. Also, loosen screws slowly.
• Never disassemble them.
• Do not allow fire to come close to them or throw them into a fire.
• Do not attempt drilling, or gas cutting.
• Do not knock them, drop them or give an impact to them.
• When disposing of them, removal of filled gas is required.

a low level of functions will result in failure. It cannot
relieve its residual pressure when the Machine is in
trouble.
