1. With the charger unplugged from the
AC outlet, connect the charger to the
battery, following the instructions given
in sections 6 and 7.
2. With the charger plugged in and
connected to the battery and chassis,
press the RATE SELECTION button
until the display shows ENGINE
START - PRESS FOR BATTERY
TEST. Wait for message to change to
ENGINE START ON. Wait two more
minutes.
3. When the display shows READY,
crank the engine until it starts or 5
seconds pass. If the engine does not
start, wait 3 minutes (until the display
shows READY) 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.
4. If the engine fails to start, charge the
battery for 5 more minutes before
attempting to crank the engine again.
5. After the engine starts, unplug the AC
power cord before disconnecting the
battery clamps from the vehicle.
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, 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 5 seconds or until
the engine cranking stops.
• Cool Down – After cranking, the charger
enters a mandatory 3 minute (180
second) cool down state. The digital
display will show COOL DOWN xxx
SECONDS REMAINING. It starts at 180
and counts down to 0. After 3 minutes,
the digital display will change to READY.
USING THE BATTERY VOLTAGE TESTER
1. With the charger unplugged from the
AC outlet, connect the charger to the
battery following the instructions given
in previous sections.
2. Plug the charger AC power cord into
the AC outlet.
3. If necessary, press the BATTERY TYPE
button until the correct type is indicated.
4. Read the voltage on the digital display.
Keep in mind that this reading is only a
battery voltage reading; a false surface
charge may mislead you. Compare the
reading to the following chart.

TESTER AND CHARGER
When first turned on, the unit operates only
as a tester, not as a charger. Selecting a
mode activates the battery charger and
deactivates the tester. Pressing the RATE
SELECTION button when the Engine Start
mode is active (except during the 180
second cool down) will shut off the charger
and activate the tester.
POWER-UP IDLE TIME LIMIT
If no button is pressed within 10 minutes
after the battery charger is first powered up,
the charger will automatically switch from
tester to charger if a battery is connected.
In that case, the charger will be set to the
6<>2A CHARGE/MAINTAIN mode and
AGM battery type.
TESTING AFTER CHARGING
After the unit has been changed from tester
to charger (by selecting a mode), it remains a
charger. To change the battery charger back
to a tester, press the RATE SELECTION
button until the display shows voltage.
NOTE: The battery tester is only designed
to test batteries. Testing a device with
a rapidly changing voltage could yield
unexpected or inaccurate results.
FAN OPERATION
It is normal for the fan to start and stop when
maintaining a fully charged battery. The fan
does not run in Tester Mode. Keep the area
near the charger clear of obstructions, to
allow the fan to operate efficiently.
RESTART
If the Mode is changed after charging has
started (by pressing the RATE SELECTION
button), the charging process will restart.
