1.Note the polarity of the battery posts by checking the identification marks on the battery: POSITIVE (POS, P or +) and NEGATIVE (NEG, N or -). The positive post is usually larger than the negative post.

2.Attach at least a 24-inch-long, 6-gauge

(AWG), insulated battery cable to NEGATIVE (NEG, N or -) battery post.

Rock and twist the clamp back and forth to be sure a solid electrical connection is made.

3.Connect the red (POSITIVE) output clamp to the POSITIVE battery post. Rock and twist the clamp back and forth to be sure a solid electrical connection is made.

4.Position yourself as far away from the battery as possible, and then connect the black (NEGATIVE) output clamp to the free end of the cable.

5.Plug the power cord into a 120V AC 2-prongwalloutlet.Thechargerwillbeset to the default state of 12V REGULAR bat- tery type, no charge rate (tester mode).

6.Press the appropriate control buttons to select the desired charge rate and battery type. Within a few seconds, the

CHARGING (yellow) LED should light and the charging process should start.

If the CHECK (red) LED is on, check for correct cable connections.

7.To disconnect the charger, unplug its power cord before attempting to discon- nect the charger clamps. Then, standing away from the battery, remove the out- put clamp from the NEGATIVE battery post. Finally, remove the output clamp from the POSITIVE battery post.

8.Clean and store the charger in a dry location.

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 CHARGING BATTERY IN THE VEHICLE. With the charger plugged in and connected to the battery of the vehicle, set the CHARGE RATE to 75A START. Only the 75A START, CHARGING, 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 75 amps for engine start. The charger delivers charge at a rate of up to 12 amps while waiting and will reset if the engine is not cranked within 5 minutes. (If the charger resets, it sets itself for a 2A charge and 12V Regular battery.) 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 least75A) as required by the starting system for
