operating the machine with an
accumulator
Warning
Be sure to handle the high-pressure
nitrogen gas enclosed in the accumulator
with care. If handled incorrectly, it could
explode and cause serious injury. Strictly
observe the following precautions:
• Do not disassemble.
• Do not allow flame near or throw it into
a fire.
• Do not drill, weld or fuse.
• Do not subject it to physical shock such
as hitting, rolling or dropping.
• Before disposing of the unit, the sealed
gas must be drained. Contact a
Takeuchi service agent for help.
For a machine with an accumulator, the
residual pressure in the auxiliary hydraulic
circuit or the working equipment circuit can
be released even after the engine is stopped.

Residual pressure refers to the pressure that
remains in the hydraulic circuit after the
operation. Release the residual pressure as
necessary by using the following steps.

within 10 minutes after the engine stopping.
1. Return the throttle controller to idle the
engine at low speed.
2. Lower the bucket and dozer blade to the
ground.
3. Check that the safety lock lever is in the
released position.
4. Stop the engine.
5. Turn the starter switch to the ON position.
6. Move or press the auxiliary hydraulic
switches several times to release the
residual pressure in the circuitry.
7. Move all the control levers and pedals
several times in all directions to release the
pressure from the working equipment
circuitry.
8. Raise the safety lock lever to engage the
lock.
