2. Use a voltmeter to check the voltage of each battery with the scrub and drive motors running. The battery with the
dead cell will read 1 or 2 volts lower than the other batteries in the system.
If the batteries in the machine are more than one year old, it's usually best to replace the whole set, rather than
replacing just one battery.

battery pack and actuator motor for setting
the drive nut limit settings.
1. Open the machine battery compartment
and disconnect the battery connector.
The battery pack is needed to power the
lift actuator motor to correctly set the IN
and OUT limit switches.
2. Connect the actuator motor to be tested
