WARNING:
Allow only qualified personnel to handle the
accumulator.
High-pressure nitrogen gas is enclosed in the
accumulator. Caution is required to prevent fires
from occurring.
Never strike the accumulator. Keep the accumulator
away from sparks and/or flames.
Do not directly heat the accumulator. Do not weld
the accumulator housing.
Be sure to release pressure before starting to work
on the pipe lines.
Let the machine travel with the ride control switch turned
AUTO and OFF to compare the machine's vertical vibration
during travel. Travel the machine at a speed faster than "Ride
Control Drive Speed Setting" displayed on the multi-monitor. If
the machine's vertical vibration is not dampened when letting
the machine travel with the ride control function activated, the
accumulator may be faulty. Consult your authorized Hitachi
dealer for check and repair.

Check the gas pressure at a regular interval. Ask your
authorized Hitachi dealer for checking.
Check Gas Pressure in Steering Accumulator

is not smooth when the steering wheel is operated. Consult
your authorized Hitachi dealer for checking the gas pressure.
