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

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

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.
