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.

With the charger plugged in and connected to the battery and chassis (see

section 6), press the CHARGE RATE button until the ENGINE START LED

is lit. The display mode will be automatically set to VOLTAGE.

Crank the engine until it starts or 3 seconds pass. If the engine does not

start, wait 3 minutes 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.

If the engine fails to start, charge the battery for 5 more minutes before

attempting to crank the engine again.
After the engine starts, move the charge rate selector switch to the off

position and unplug the AC power cord before disconnecting the battery

clips from the vehicle.
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.
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 amps for engine start. The charger delivers a

charge at the slow charge rate 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 rdy.
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 in seconds.
Cool Down – After cranking, the charger 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 delivered 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 displaying the countdown to

displaying rdy. The CHARGING LED

will then be lit.
