Automatic Charging Mode

When an Automatic Charge is performed, the charger switches to the Maintain Mode

(see below) automatically after the battery is charged. For a battery with a starting

voltage under 1 volt, use a manual charger to pre-charge the battery for five minutes to

get additional voltage into the battery.
Aborted Charge

If charging cannot be completed normally, charging will abort. When charging aborts,

the charger’s output is shut off and the digital display will blink on and off. The charger

ignores all buttons. To reset after an aborted charge, unplug the charger from the AC

outlet, wait a few moments and plug it back in.
Completion of Charge

Charge completion is indicated by the CHARGED LED. When lit, the charger has

switched to the Maintain Mode of operation.
Maintain Mode (Float-Mode Monitoring)

When the CHARGED LED is lit, the charger has started Maintain Mode. In this

mode, the charger keeps the battery fully charged by delivering a small current when

necessary. The voltage is maintained at a level determined by the BATTERY TYPE

selected.
NOTE: The maintain mode technology utilized in Schumacher chargers allows you to

safely charge and maintain a healthy battery for extended periods of time. However,

problems with the battery, electrical problems in the vehicle, improper connections

or other unanticipated conditions could cause excessive current draws. As such,

occasionally monitoring your battery and the charging process is recommended.
Using the Engine Start feature

Your battery charger can be used to jumpstart your car if the battery is low. Follow these

instructions on how to use the ENGINE START feature.

Follow all safety instructions and precautions for charging your battery.

Wear complete eye protection and clothing protection. Charge your battery in a well-

ventilated area.

Using the ENGINE START feature WITHOUT a battery installed in

the vehicle could cause damage to the vehicle’s electrical system. NOTE: If you have

charged the battery and it still will not start your car, do not use the engine start feature,

or it could damage the vehicle’s electrical system.

With the charger unplugged from the AC outlet, connect the charger to the battery

following the instructions given in section 6 (FOLLOW THESE STEPS WHEN THE

BATTERY IS INSTALLED IN A VEHICLE).
Plug the charger AC power cord into the AC outlet.

With the charger plugged in and connected to the battery of the vehicle, set the

battery size selector switch to the engine start position.
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.

NOTE: During extremely cold weather, or if the battery is under 2 volts, charge the

battery for 5 minutes before cranking the engine.

If the engine fails to start, charge the battery for 5 more minutes before attempting to

crank the engine again.
After the engine starts, move the battery size selector switch to the OFF position by

pressing the Battery Size button until no LEDs are lit in the battery size section and

unplug the AC power cord before disconnecting the battery clips from the vehicle.
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.
