MAINTENANCE INSTRUCTIONS 13.
After use and before performing maintenance, unplug and disconnect the 13.1
battery charger (see Sections 6, 7 and 8).
Use a dry cloth to wipe all battery corrosion and other dirt or oil from the
13.2
terminals, cords, and the charger case.
Ensure that all of the charger components are in place and in good working
13.3
condition, including the plastic boots on the battery clips.
Servicing does not require opening the unit, as there are no user-serviceable
13.4
parts.
STORAGE INSTRUCTIONS 14.
Store the charger unplugged, in an upright position. The cord will still conduct 14.1
electricity until it is unplugged from the outlet.
Store inside, in a cool, dry place (unless you’re using an on-board Marine
14.2
Charger).
Do not store the clips on the handle, clipped together, on or around metal, or
14.3
