Check Accumulator Function, Gas Leakage,
Looseness, and Damage
--- every 500 hours
WARNING: Allow only qualified personnel to service
the accumulator.
High-pressure nitrogen gas is enclosed in the
accumulator. (N
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
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. Also, ensure the brake oil pressure gauge on the
monitor indicates the maximum value.
3. Note how many times the brake pedal is stepped:
Check that the brake pedal can be stepped more than
5 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.
