1. With the charger unplugged from the AC outlet, connect the charger to the battery following the
instructions given in Follow These Steps When Battery Is Installed In Vehicle.
2. Connect the charger to a live, grounded 120V AC outlet.
3. With the charger plugged in and connected to the battery and chassis, press the Rate Selection
button until the Engine Start LED is lit.
4. Press the START/STOP button to begin Engine Start. Engine Start will not begin without pressing
the START/STOP button.
5. Wait 2 minutes before cranking the engine.
6. Crank the engine until it starts or 3 seconds pass. If the engine does not start, wait 3 minutes before
cranking again. This allows the charger and battery to cool down. The Engine Start LED will blink during
the 3 minute cool-down. NOTE: During extremely cold weather, or if the battery is under 2 volts,
charge the battery for 5 minutes before cranking the engine.
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.
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 Engine Start LED. After three minutes, the % LEDs will light in
sequence and the Engine Start LED will be lit.
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, clipped to the handle, on or
around metal, or clipped to the cables.
