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 the speed faster than
5 km/h (3.1 mph). 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 nearest authorized dealer for check and repair.
Check Gas Pressure in Ride Control Accumulator
(Optional)
--- every 2000 hours
Check the gas pressure at a regular interval. Ask your nearest
authorized dealer for checking.
