7.12 AUXILIARY POWER
NOTICE
• When the emergency power is in use, do not per-
form two or more functions at the same time, be-
cause certain function operation may have no
response due to small flow in the emergency mo-
tor or pump.
• The emergency power switch can only be used for
a short time (to fully lower and retract the platform
from the maximum angle and maximum length)
when the main power source is not working, be-
cause long-time operation may bring damage to
the motor.
In the event of main power source failure, the auxiliary
power can be used to perform the desired function
operation.
Perform operation from the ground:
Move and hold the emergency power switch, activate
the desired movement switch to perform the required
function operation.
Perform operation from the platform:
Depress the foot switch, move and hold the emergency
power switch, and activate the desired movement switch
to perform the required function operation.
