MAINTENANCE INSTRUCTIONS 14.
Before performing maintenance, unplug and disconnect the battery charger 14.1
(see Sections 6, 7 and 8).
After use, unplug the charger and use a dry cloth to wipe all battery corrosion
14.2
and other dirt or oil from the terminals, cords, and the charger case.
Ensure that all of the charger components are in place and in good working
14.3
condition, including the plastic boots on the battery clips.
Servicing does not require opening the unit, as there are no user-serviceable
14.4
parts.

electricity until it is unplugged from the outlet.
Store inside, in a cool, dry place (unless you’re using an on-board Marine
15.2
Charger).
Do not store the clips on the handle, clipped together, on or around metal, or
15.3
clipped to cables.
