Preventive Maintenance

1.
For optimum performance, the system requires a fully charged battery to maintain required currents
and voltages. Keep battery at full capacity whenever possible.
2.
Check battery terminals and other battery connections, the controller and the jacks for corrosion and
loose or damaged connections.
3. Remove dirt, road debris and grease from jacks as needed. Then lightly lubricate the jack screw and
wipe off any excess lubrication, leaving only a thin coating for protection.
