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.

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 150 amps for engine start. The charger delivers charge at a rate of up
to 10 amps while waiting and will reset if the engine is not cranked within 15 minutes.
(If the charger resets, it sets itself to the default start up settings). While waiting for
cranking, the digital display shows
.
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. The digital display shows a countdown of the remaining crank
time. It starts at 10 and counts down to 0.
Cool Down
–
After cranking, the charger enters a mandatory 4 minute (240 second)
cool down state. During this period, no settings can be changed. The buttons are
ignored. The digital display indicates the remaining cool down time in seconds. It
starts at 240 and counts down to 0. After 4 minutes, the digital display will change from
displaying the countdown back to displaying
indicating that another crank cycle can
be started.
