MOTOR OPERATION

Power/Emergency Stop

The Power/Emergency Stop switch, when pulled out (on),
provides battery power for all machine functions. The switch
should be pushed in (off) when recharging the batteries or
parking the machine overnight.
NOTE: If equipped with the optional on-board generator, the
Emergency Stop switch must be left on (pulled out) to
allow for automatic charging of the batteries.
Within about 2 seconds of pulling the switch out, the
machine will perform a diagnostic check of the various elec-
trical circuits, and if everything is OK, the platform alarm will
beep once. During this time the lights on the indicator panel
will also blink once as a bulb check.
