Check Accumulator Function, Gas Leakage,
Looseness, and Damage
--- every 500 hours
d
WARNING: Allow only qualified personnel to
service the accumulator.
High-pressure nitrogen gas is enclosed in the
accumulator. (N
2
is inert, and will not burn.)
Never strike the accumulator. Keep the
accumulator away from heat sources.
Do not weld the accumulator housing.
Be sure to release oil pressure before starting to
work on the brake circuit.
1. Check that alarm function is activated:
Check that when the brake pedal is strongly stepped
more than 5 strokes with the key switch ON and the
engine stopping, the monitor indicators come ON.
2. Note that alarm function is deactivated:
Start the engine. Run the engine at 1,200 RPM (min
-1
)
to pressurize the accumulator. Check that when the
pressure builds in the accumulator, the alarm buzzer
stops sounding and the brake oil pressure indicator
goes OFF.
3. Note how many times the brake pedal is stepped:
Check that the brake pedal can be stepped more
than 3 strokes before the monitor indicators come
ON with the key switch ON, the engine stopping, and
brake oil pressure gauge in the right of the monitor
display indicates the maximum level.
Three points described above must be confirmed
as operational. Besides the above points, check the
accumulator for gas leakage, looseness, and damage. If any
abnormality is found, immediately consult your nearest
authorized dealer.
