Harbor Freight Tools 66783 operating instructions Charger Location

d. Add distilled water in each cell until battery acid reaches level specified by battery manufacturer. This helps purge excessive gas from cells. Do not overfill. For a battery without cell caps, carefully follow manufacturer’s recharging instructions.

e. Study all battery manufacturer’s specific precautions such as removing or not removing cell caps while charging and recommended rates of charge.

f.Determinate voltage of battery by referring to car owner’s manual and make sure that output voltage selector switch is set at correct voltage. If charger has adjustable charge rate, charge battery initially at lowest rate.

13.CHARGER LOCATION

a.Locate charger as far away from battery as the DC cable permits.

b.Never place charger directly above battery being charged; gases from battery will corrode and damage charger.

c.Never allow battery acid to drip on charger when reading gravity or filling battery.

d.Do not operate charger in a closed-in area or restrict ventilation in any way.

e.Do not set a battery on top of charger.

14.DC CONNECTION PRECAUTIONS

a.Connect and disconnect DC output clips only after removing AC cord from electric outlet. Never allow clips to touch each other.

b.Attach clips to battery and chassis as indicated in 15 (e), 15 (f), 16 (b), and 16 (d).

15.Follow these steps when battery is installed in vehicle. A spark near battery may cause battery explosion. To reduce risk of a spark near battery:

a.Position AC and DC cords to reduce the risk of damage by hood, door, or moving engine parts.

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

c.Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger diameter than NEGATIVE (NEG, N, -) post.

d.Determine which battery post is grounded (connected) to the chassis. If negative post is grounded to chassis (as in most vehicles), see (e). If the positive post is grounded to the chassis, see (f).

e.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. Do not connect clip to the carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy gauge metal part of the frame or engine block.

f.For positive-grounded vehicle, only 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. Do not
