12. MAINTENANCE AND CARE
A minimal amount of care can keep your
battery charger working properly for years.
• Clean the clamps each time you are
finished charging. Wipe off any battery
fluid that may have come in contact with
the clamps to prevent corrosion.
• Occasionally cleaning the case of the
charger with a soft cloth will keep the
finish shiny and help prevent corrosion.
• Coil the input and output cords neatly
when storing the charger. This will help
prevent accidental damage to the cords
and charger.
• Store the charger unplugged from the AC
power outlet in an upright position.
• Store inside, in a cool, dry place. Do not
store the clamps clipped together, on or
around metal, or clipped to the cables.

Troubleshooting
PROBLEM
POSSIBLE CAUSE
SOLUTION
Battery clamps do not
spark when touched
together.
The charger is equipped
with an auto-start feature.
It will not supply current to
the battery clamps until a
battery is properly connected.
The clamps will not spark if
touched together.
No problem; this is a normal
condition.
The charger will not
turn on when properly
connected.
AC outlet is dead.
Poor electrical connection.
Check for open fuse or circuit
breaker supplying AC outlet.
Check power cord and extension
cord for loose fitting plug.
