The service brakes on this machine are backed up by
accumulators. In the event of accumulator failure, the foot
brakes would be inoperative with the engine stopped.
It is essential that the operation of the accumulators is
checked regularly, using the following procedure:
1 Park the machine on firm level ground, lower the
attachments to the ground, apply the park brake, stop
the engine and exhaust the brake system by
operating the foot brake repeatedly.
2 Start the engine and run at high rpm for 1 minute.
3 Stop the engine, apply the foot brake, count the
number of operations of the brake pedal until the
system is exhausted.
If less than 6 or the brake failure warning light illuminates
immediately then one or more of the accumulators may
have failed and need immediate replacement.
