CEN-TECH 63873 Owner's Manual & Safety Instructions page 4

12. PREPARING TO CHARGE
a. If necessary to remove battery from vehicle
to charge, always remove grounded terminal
from battery first. Make sure all accessories in
the vehicle are off, so as not to cause an arc.
b. Be sure area around battery is well
ventilated while battery is being charged.
c. Clean battery terminals. Be careful to keep
corrosion from coming in contact with eyes.
d. Add distilled water in each cell until battery
acid reaches level specified by battery
manufacturer. Do not overfill. For a battery
without removable cell caps, such as valve
regulated lead acid batteries, carefully follow
manufacturer's recharging instructions.
e. Study all battery manufacturer's
specific precautions while charging and
recommended rates of charge.
f. Determine voltage of battery by referring
to vehicle owner's manual and make sure
it matches output rating of battery charger.
If charger has adjustable charge rate,
charge battery initially at lowest rate.
13. CHARGER LOCATION
a. Locate charger as far away from
battery as DC cables permit.
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 electrolyte
specific 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 setting any charger switches to "off" position
and 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), and 16(b) through 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 cables to reduce risk of
damage by hood, door, or moving engine part.
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.
Page 4 For technical questions, please call 1-888-866-5797.
d. Determine which post of battery is
grounded (connected) to the chassis. If
negative post is grounded to chassis (as
in most vehicles), see (e). If 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. Do not connect clip to carburetor,
fuel lines, or sheet-metal body parts.
f. For positive-grounded vehicle, connect
NEGATIVE (BLACK) clip from battery charger
to NEGATIVE (NEG, N, –) ungrounded post
of battery. Do not connect clip to carburetor,
fuel lines, or sheet-metal body parts.
g. When disconnecting charger, turn switches
to off, disconnect AC cord, and then
remove clip from battery terminal.
h. See operating instructions for
length of charge information.
16. FOLLOW THESE STEPS WHEN BATTERY
IS OUTSIDE VEHICLE. A SPARK NEAR THE
BATTERY MAY CAUSE BATTERY EXPLOSION.
TO REDUCE RISK OF A SPARK NEAR BATTERY:
a. Check polarity of battery posts. POSITIVE
(POS, P, +) battery post usually has a larger
diameter than NEGATIVE (NEG, N, –) post.
b. Connect POSITIVE (RED) charger clip to
POSITIVE (POS, P, +) post of battery.
c. Position yourself and free end of cable
as far away from battery as possible
– then connect NEGATIVE (BLACK)
charger clip to free end of cable.
d. Do not face battery when
making final connection.
e. When disconnecting charger, always do so in
reverse sequence of connecting procedure.
f. A marine (boat) battery must be removed and
charged on shore. To charge it on board requires
equipment specially designed for marine use.
17. Wear ANSI-approved splash-resistant
safety goggles and heavy-duty rubber
work gloves whenever connecting,
disconnecting, or working near battery.
Battery acid can cause
permanent blindness.
18. Do not use Start setting to charge
batteries. Use to jump start only.
19. Maintain labels and nameplates on the charger.
These carry important safety information.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.
20. This product is not a toy.
Keep it out of reach of children.
