USING THE ENGINE START FEATURE
Your battery charger can be used to jump
start your car if the battery is low. Follow
all safety instructions and precautions for
charging your battery. Wear complete eye
protection and protective clothing.
WARNING: Using the ENGINE START
feature WITHOUT a battery installed in
the vehicle could cause damage to the
vehicle's electrical system.
NOTE: During extremely cold weather, or
if the battery is under 2 volts, boost the
battery for 5 minutes before cranking the
engine.
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.
Have the battery checked.
1. With the charger unplugged from the
AC outlet, connect the charger to the
battery following the instructions given
in Charging a Battery in the Vehicle.
2. Plug the charger AC power cord into
the AC outlet.
3. With the charger plugged in and
connected to the battery and chassis,
select the ENGINE START rate. If
the battery is properly connected, the
yellow/orange 85A Engine Start LED
will light solid and the display will show
"ON". If display shows "0.0", check the
battery connections. If the display
does not show "On", check the battery
connections. When the Engine Start
output is enabled the display will
show "rdy".
4. Crank the engine until it starts or 5
seconds pass. If the engine does not
start, wait a few minutes before cranking
again. This allows the charger and
battery to cool down.
NOTE: After 3 minutes in Engine Start
mode, the charger will enter into a cool-
down period of 180 seconds, to allow the
charger and the battery to cool down.
The digital display indicates the remaining
cool down time in seconds. It starts at 180
and counts down to 0. After 3 minutes, the
digital display will change from displaying
the countdown to displaying "rdy".
5. If the engine fails to start, use the 30A
Booster rate for 5 more minutes before
attempting to crank the engine again.
6. After the engine starts, unplug the AC
power cord before disconnecting the
battery clamps from the vehicle.
7. 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.
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. 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.
6V Battery
Voltage Reading
6.4 or more
6.1 to 6.3
Less than 6.1
TESTER AND CHARGER
When first turned on, the unit operates
only as a tester, not as a charger.
Selecting a charge rate activates the
battery charger and deactivates the
tester. Pressing the RATE SELECTION
button when the ENGINE START LED
is lit (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 Charging/Maintaining rate
and AGM battery type.
TESTING AFTER CHARGING
After the unit has been changed from
tester to charger (by selecting a desired
rate), it remains a charger. To change the
battery charger back to a tester, press the
RATE SELECTION button until all rate
LEDs are off.
NOTE: The battery tester is only designed
to test batteries. Testing a device with
a rapidly changing voltage could yield
unexpected or inaccurate results.
