USING ENGINE START

Your battery charger can be used to jump
start your car if the battery is low. Fol-
low these instructions on how to use the
ENGINE START feature.
IMPORTANT: Follow all safety instructions
and precautions when charging your bat-
tery. Wear complete eye protection and
clothing protection. Charge your battery
in a well-ventilated area.
IMPORTANT: Using the ENGINE START
feature WITHOUT a battery installed in
the vehicle could cause damage to the
vehicle's electrical system.
1. For battery connections, see page 6
and follow instructions 1 – 6 of CHARG-
ING BATTERY IN THE VEHICLE.
With the charger plugged in and con-
nected to the battery of the vehicle,
press the CHARGE START button
until the ENGINE START LED is lit.
Only the ENGINE START, CHARG-
ING, CONNECTED, and VOLTAGE
LEDs should be lit, unless the 6V
REGULAR battery type has been se-
lected. In that case, the 6V REGULAR
LED will also be lit.
2. Crank the engine for no more than 5
seconds. If engine does not start, wait
3 minutes before cranking again.
3. After the engine starts, unplug the power
cord before disconnecting the output
clamps from the battery.
4. Clean and store the charger in a dry
location.
NOTE: During the starting sequence listed
above, the charger is set to one of three
states.
1. Wait for cranking - The charger
waits until the engine is actually being
cranked before delivering 120 amps
for engine start. The charger delivers
charge at a rate of up to 15 amps while
waiting and will reset if the engine
is not cranked within 15 minutes. (If
the charger resets, it sets itself for a
SMALL BATTERY charge and 12V
REGULAR BATTERY type.) While
waiting for cranking, the digital display
shows the battery voltage (it can't be
set to percent).
2. Cranking - When cranking is detected,
the charger will automatically deliver up
to its maximum output (at least 120A)
as required by the starting system for
up to 5 seconds or until the engine
cranking stops. The digital display
shows a countdown of the remaining
crank time in seconds. It starts at 5 and
counts down to 0.
3. Cool Down - After cranking, the char-
ger enters a mandatory 3-minute (180
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 180 and counts
down to 0. The ENGINE START LED
blinks once every second. During the
cool down period, no current is deliv-
ered to the battery. After 3 minutes, the
ENGINE START LED will stop blinking
and will light continuously, indicating that
another crank cycle can be started. The
digital display will change from display-
ing the countdown back to displaying
the battery voltage. The CHARGING
LED will then be lit.
ENGINE STARTING NOTES:
• If the battery is disconnected during
the cool down period, the charger will
reset.
