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 connected to the battery of the vehicle, press the CHARGE START button until the ENGINE START LED is lit. Only the

ENGINE START, CHARGING, CON- NECTED and VOLTAGE LEDs should be lit.

2.Crank the engine for no more than 5 seconds. If engine does not start, wait at least 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 65 amps for engine start. The charger delivers charge at a rate of up to 10 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 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 65A) 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.
