battery operation. For this reason, it is of utmost importance that each time before using your charger, you
read this manual and follow the instructions exactly.
WARNING: Handling the cord on this product or cords associated with accessories sold with this product, will expose you to lead, a
chemical known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.

result in fire, electric shock, or injury.
WARNING: Risk of explosive gas.
12. Locate charger as far away from battery as DC charger
cables permit.
4. When disconnecting the battery charger, pull by the plug
not by the cord. Pulling on the cord may cause damage to
cord or plug.
5. Locate battery power cord so it cannot be stepped on, tripped
over, or subjected to damage or stress.

14. NEVER charge a frozen battery. If battery fluid (electrolyte)
is frozen, bring into a warm area to thaw before charging.
15. NEVER allow battery acid to drip on charger when reading
specific gravity or filling battery.
6. Do not operate charger with damaged cord or plug. Have
cord replaced immediately.
16. NEVER set a battery on top of charger.
17. NEVER place charger directly above battery being charged.
Gases from battery will corrode and damage charger.
18. NEVER touch the battery clamps together when the charger
is energized.
19. NEVER crank engine with charger attached to battery.

OPERATING INSTRUCTIONS: CHARGING BATTERY OUT OF THE VEHICLE
When charging battery out of the 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 battery may cause battery explosion. WARNING: When removing battery
from vehicle or boat, disconnect grounded post 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. Perform these steps with the ON/OFF switch in the OFF

OPERATING INSTRUCTIONS: CHARGING BATTERY IN VEHICLE
When charging battery in vehicle, take care to determine the battery type and which pole is grounded. To reduce risk of a spark near
battery, follow these steps when battery is inside vehicle. WARNING: A spark near the battery may cause battery explosion.
1. Perform these steps with the ON/OFF switch in the OFF
GR
(
position.
2. Position AC power cord and DC charging cords to reduce
risk of damage by hood, door, or moving engine parts.
3. Stay clear of fan blades, belts, pulleys, and other parts that
can cause injury.
4. 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.
FIGURE 2: CONNECTION TO NEGATIVE
GROUNDED BATTERY
5. Determine which post of battery is grounded (connected)
POSITIVE GROUNDED POST
to chassis. NOTE: The negative post is normally grounded.
6B. For positive-grounded vehicle, connect NEGATIVE (BLACK)
clamp from battery charger to NEGATIVE (NEG, N, -)
ungrounded post of battery. Connect POSITIVE (RED)
clamp to vehicle chassis or engine block away from battery.
Connect to a heavy-gauge metal part of the frame or engine
block.
NEGATIVE GROUNDED POST
6A. For negative-grounded vehicle, connect POSITIVE (RED)
clamp from battery charger to POSITIVE (POS, P, +)
ungrounded post of battery. Connect NEGATIVE (BLACK)
clamp to vehicle chassis or engine block away from battery.
Connect to a heavy-gage metal part of the frame or engine
block.
7. Plug charger AC cord into a grounded 120 volt outlet.
8. Select the ON position on the ON/OFF switch.
WARNING: Do not connect clamp to carburetor, fuel lines,
or sheet-metal body parts. NOTE: Attach clamps to battery
post and twist or rock back and forth several times to make
a good connection. This tends to keep clamps from slipping
off terminals and helps to reduce risk of sparking.
9. When battery is fully charged, push the ON/OFF switch to
OFF, unplug charger from AC power source.
10. Remove charger clamps from (1) chassis and (2) battery
post, in that order.
