1. position the AC and DC cords so they cannot be damaged by the hood, a door or a moving engine part.
2. stay clear of fan blades, belts, pulleys, and other parts that can cause personal injuries.
3. check the polarity of the battery posts. A positive (pos, p+) battery post usually has a larger diameter than the
negative (neg., n-) post.
4. determine which battery post is connected to the chassis (in other words, which battery post is grounded). If
the negative post is grounded (as in most vehicles), see item 5. If the positive post is grounded, see item 6.
5. for a negative-grounded vehicle, connect the positive (red) clip from the battery charger to the positive
ungrounded post of the battery first. Then connect the negative (black) clip to the vehicle chassis of the engine
block but stay clear of the battery and fuel line. Do not connect the clip to the carburettor, fuel lines or any
sheet metal parts. Connect it to a heavy gauge metal part of the frame or engine block.
6. for a positive-grounded vehicle, connect the negative (black) clip from the battery charger to the negative (neg,
n.-) ungrounded post of the battery first. Connect the positive (red) clip to the vehicle chassis or engine block
but stay clear of of the battery and fuel line. Do not connect the clip to the carburettor, fuel lines or any sheet
metal parts. Connect it to a heavy gauge metal part of the frame or engine block.
7. connect the charger to an electric outlet with the supplied power cord.
8. when disconnecting the charger, disconnect the AC cord, remove the clip from the vehicle chassis and then
remove the clip from the battery terminal.
b. Follow these steps when the battery is outside the vehicle:
A spark near the battery may cause battery explosion. To reduce the risk of a spark near the battery:
1. check the polarity of the battery posts. A positive (pos, p+) battery post usually has a larger diameter than the
negative (neg., n-) post.
2. connect an insulated battery output cable of at least 1.8m and 0.75mm³ from the charger to the negative (neg.
n.-) battery post.
3. connect the positive (red) charger clip to the positive (pos, p.+) post of the battery.
4. hold the free end of the cable as far away from battery as possible, then connect the negative (black) charger
clip to the free end of the cable.
5. do not face the battery when making the final connection.
6. connect the charger to an electric outlet with the supplied power cord.
7. when disconnecting the charger, always proceed in reverse order of connection and sever the first connection
while standing as far away from the battery as possible.
7. User instructions
a. Automatic monitoring
Your new battery charging system is completely automatic and can be left on whenever there is input power
available. The charger output depends on the condition of the battery it is charging. When the battery is fully charged,
the indicating light will turn green and the charger will automatically switch to storage charge mode and monitor and
maintain the battery at full charge.
b. Cable connections
The battery charging system is equipped with two output leads, a red positive lead and a black negative lead. Only
connect or disconnect the output leads before plugging into an AC power outlet.
For all battery types: connect the red positive (+) lead to the positive terminal of the battery. Connect the black
negative lead (-) to the negative terminal of the battery.
If the charger is connected to a battery for long periods of time, check the water levels as directed by the battery
manufacturer as to ensure they remain at the proper level.
