7.6 AUXILIARY POWER SYSTEM
The auxiliary power system relies on two 12V batteries
in parallel to provide power for a 12V DC motor which
drives the gear pump to work. When the main power
source fails, the auxiliary power system can be used to
lower the operator in the platform to the ground. The
auxiliary power system cannot be used as the main
power source to drive the travel function, but can be
used to return the machine to the stowed position in a
short time.
