BRAKE ACCUMULATOR MAINTENANCE - CONTINUED
CHARGING - CONTINUED
Operate service brakes several times.
N OT E
If brake accumulator has less than half of required amount of precharge pressure, accumulator should be
charged. Then charge accumulator again after applying service brakes repeatedly to prevent trapping oil in
accumulator. Oil in accumulator will give inaccurate precharge reading.
Charge accumulator again.
Apply service brakes 20 to 30 times. This will release any pressure that may be in brake accumulators.
Remove cover (15) from brake accumulator. Remove cap (16) from valve assembly on brake accumulator.
