5.Connecting to a negative-grounded system: Connect the red (POSITIVE) output clamp to the POSITIVE post of the battery. Rock and twist the clamp back and forth to be sure a solid electrical connection is made. Then connect the black (NEGATIVE) output clamp to a heavy, unpainted metal part of the chassis or engine block, away from the battery (see figure).

NEGATIVE GROUNDED SYSTEM

DO NOT connect clamp to negative battery post, carburetor, fuel line or sheet metal part.

Connecting to a positive-grounded system: Connect the black (NEGA- TIVE) output clamp to the NEGATIVE post of the battery. Rock and twist the clamp back and forth to be sure a solid electrical connection is made. Then connect the red (POSITIVE) output clamp to a heavy, unpainted metal part of the chassis or engine block, away from the battery. DO NOT connect clamp to positive battery post, carburetor, fuel line or sheet metal part.

6.Plug power cord into a 120V AC

2-prong wall outlet. The charger will be set to the default state of 12V REGULAR battery type, no charge rate (tester mode). The CONNECTED

LED should be lit. If the CONNECTED LED is not lit, check for correct cable connections.

7.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.

8.To disconnect the charger, unplug its power cord before attempting to disconnect the output clamps. Then, standing away from the battery, re- move the output clamp from the chas- sis or engine block. Finally, remove the output clamp from the battery post.

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

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-prong wall outlet. The charger will be set to the default state of 12V REGULAR batterytype,nochargerate(testermode).
