E.OPERATING INSTRUCTIONS: CHARGING BATTERY IN VEHICLE

When charging battery in the vehicle, take care to determine the battery type and which post is grounded. To reduce risk of a spark near battery, follow these steps when battery is installed in vehicle. WARNING: A spark near battery may cause battery explosion.

1.Position AC power cord and DC charging cords to reduce risk of damage by hood, door, or moving engine parts.

2.Stay clear of fan blades, belts, pulleys, and other parts that can cause injury.

3.Check polarity of battery posts. Battery case will be marked by each post: POSITIVE (POS, P, +) and NEGATIVE (NEG, N, -). NOTE: The positive battery post usually has a larger diameter than the negative post.

4.Determine which post of battery is ground (connected) to chassis.

NOTE: The negative post is normally grounded.

NEGATIVE GROUNDED POST

5A. For negative-grounded vehicle, connect POSITIVE (RED) clip from battery charger to POSITIVE (POS, P, +) ungrounded post of battery. Connect NEGATIVE (BLACK) clip to vehicle chassis or engine block away from battery. Connect to a heavy gauge metal part of the frame or engine block.

POSITIVE GROUNDED POST

5B. For positive-grounded vehicle, connect NEGATIVE (BLACK) clip from battery charger to NEGATIVE (NEG, N, -) ungrounded post of battery. Connect POSITIVE (RED) clip to vehicle chassis or engine block away from battery. Connect to a heavy gauge metal part of the frame or engine block.

WARNING: Do not connect clip to carburetor, fuel lines, or sheet-

metal body parts. NOTE: Attach clips to battery post and twist or rock back and forth several times to make a good connec- tion. This tends to keep clips from slipping off terminals and helps to reduce risk of sparking.

6.Make all desired settings before applying AC power to the charger.

7.Observe the meter for proper response, if something does not look right, refer to the trouble shooting section of this manual.

8.When battery is fully charged, unplug charger from AC outlet.

9.Remove charger clips from (1) chassis and (2) battery post, in that order.

F.OPERATING INSTRUCTIONS: CHARGING BATTERY OUT OF VEHICLE

When charging battery out of vehicle, take care to determine the battery type. To reduce risk of a spark near battery, follow these steps when battery is outside vehicle. WARNING: A spark near the battery may cause battery explosion. WARNING: When removing battery from vehicle or boat, disconnect grounded pole first. When disconnecting, make sure all accessories are off, so as not to cause an arc. (NOTE: A marine (boat) battery must be removed and charged on shore. (To charge on board requires special equipment designed for marine use.) WARNING: When reinstalling battery, attach the ground post first.

1. Check polarity of battery posts. Battery case will be marked

by each post: POSITIVE (POS, P, +) and NEGATIVE (NEG,

N, -). NOTE: The positive battery post usually has a larger

diameter than the negative post.

2.

Attach a 24-inch long (or longer) 6-gauge (AWG) insulated

 

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

3.

Connect POSITIVE (RED) charger clip to POSITIVE (POS,

 

P, +) post battery. Rock clip back and forth to make good

 

connection.

4.

Position yourself and free end of 24 inch cable as far away

 

from battery as possible. Then connect NEGATIVE (BLACK)

 

charger clip to free end of cable.

 

WARNING: Do not face battery when making final

 

connection. Rock clip back and forth to make a good

manual.

7.

When battery is fully charged, unplug charger from AC power

 

source.

8.When battery is fully charged and charger is unplugged,

(1)remove clip from end of Negative end of cable, and

(2)remove clip from Positive battery post, in that order.

9.Clean and store battery charger.

WARNING: Be sure area around battery is well ventilated while battery is being charged. Gas can be forcefully blown

away by using a piece of cardboard or other non-metallic mate- rial as a fan.
