Manual Charging Mode

When you select the 40 Amp Manual Mode charge rate, you will be charging in manual mode. You must set the timer to the proper time (see Timer section). If you want to charge more than 2¼ hours, then set the timer in the 24H position. Be sure to monitor the charging procedure and stop it when the battery is charged. Not doing so may cause damage to your battery or result in other property damage or personal injury.

Aborted Charge

If charging can not be completed normally, charging will abort. When charging aborts, the charger’s output is shut off. To reset after an aborted charge, either disconnect the battery or unplug the charger.

Completion of Charge

Charge completion is indicated by the CHARGED (green) LED. When lit, the charger has switched to the Maintain Mode of operation.

Maintain Mode (Float-Mode Monitoring)

When the CHARGED (green) LED is lit, the charger has started Maintain Mode. In this mode, the charger keeps the battery fully charged by delivering a small current when necessary. If the battery voltage drops below a preset level, the charger will go back into Charge Mode until the battery voltage returns to the full charge level, at which point the charger will return to Maintain Mode.

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.

This product is rated for 3 seconds of engine cranking.

WARNING 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.

IMPORTANT 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.

IMPORTANT Do not leave the charger in ENGINE START Mode for more than ten minutes at a time; this may damage the charger.

1.Set the charge rate switch and the timer to the OFF position.

2.With the charger unplugged from the AC outlet, connect the charger to the battery following the instructions given in Section 5 (FOLLOW THESE STEPS WHEN THE BATTERY IS INSTALLED IN A VEHICLE).

3.Plug the charger AC power cord into the AC outlet, and then move the timer switch from OFF to the 24H position.

4.With the charger plugged in and connected to the battery of the vehicle, set the charge rate selector switch to the engine start position.

5.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.

6.If the engine fails to start, charge the battery for 5 more minutes before attempting to crank the engine again.

7.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.

8.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.
