7. If the engine fails to start, charge the
battery for 5 more minutes before
attempting to crank the engine again.
8. After the engine starts, unplug the AC
power cord before disconnecting the
battery clamps from the vehicle.
9. Clean and store the charger in a dry
location.
NOTE: If the engine does turn over but
never starts, there is not a problem with
the starting system; there is a problem
somewhere else with the vehicle. STOP
cranking the engine until the other problem
has been diagnosed and corrected.

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.

ENGINE STARTING NOTES
During the starting sequence listed above,
the charger is set to one of three states:
• Wait for cranking – The charger waits until
the engine is actually being cranked before
delivering the amps for Engine Start.
• Cranking – When cranking is detected,
the charger will automatically deliver up
to its maximum output as required by the
starting system for up to 3 seconds or until
the engine cranking stops.
• Cool Down – After cranking, the
charger enters a mandatory 3 minute
(180 second) cool down state. This is
indicated by the blinking
LED. After three minutes, the
LEDs will light in sequence and the
Engine Start LED will be lit.
• 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, clipped
to the handle, on or around metal, or
clipped to the cables.
