NOTE: During extremely cold weather,

or if the battery is under 2 volts, charge

the battery for 5 minutes before cranking

the engine.

5. If the engine fails to start, use the

60A Boost rate for 5 minutes before

attempting to crank the engine again.

6. After the engine starts, press the ON/

OFF switch to turn OFF, 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 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 the battery charged

percentage (it cannot be set to voltage).

After 5 seconds, the display will change

to ENGINE START READY.

• 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. The

digital display shows a countdown of the

remaining crank time.

• Cool Down – After cranking, the charger

enters a mandatory 3 minute (180 second)

cool down state. The digital display will

show ENGINE START COOL DOWN XXX

SECONDS REMAINING. It starts at 180

and counts down to 0. After 3 minutes,

the digital display will change to ENGINE

START READY. The CHARGING (yellow/

orange) LED will then be lit.

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’s AC power cord into

the AC outlet.

3. Set the ON/OFF switch to Boost/

Charge/Maintain. DO NOT choose a

rate with the Rate Selection button.

4. If necessary, press the BATTERY TYPE

button until the correct type is indicated.

5. 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 rst 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 rst 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 charge at the 6A<>2A charge rate

and Gel battery type.

TESTER WITHOUT TIME LIMIT

If either the DISPLAY MODE or BATTERY

TYPE button is pressed within the rst

10 minutes after the battery charger is

powered up, the unit will remain a tester

(not a charger) indenitely, unless a

charge rate is selected.

TESTING AFTER CHARGING

After the unit has been changed from

tester to charger (by selecting a charge

rate), it remains a charger. To change the

battery charger back to a tester, press the

RATE SELECTION button until all charge

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.
