Preventive Maintenance

1. For optimum performance, the system requires
full battery current and voltage. The battery must be
maintained at full capacity.
2. Check the terminals and other connections at the
battery, 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.
