3. If it is necessary to remove battery from vehicle to charge, or to clean terminals, always remove
grounded terminal from battery first. Make sure all accessories in the vehicle are off, so as not to
cause an arc.
4. Clean battery terminals, taking care to avoid getting corrosive material in eyes.
5. 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 (maintenance
free), carefully follow manufacturer’s charging instructions.
6. Study all battery manufacturer’s specific precautions, such as removing or not removing cell caps
while charging, and recommended rates of charge.
7. Determine voltage of battery to be charged by referring to the vehicle manual. The unit is for
charging a 12 volt lead-acid battery only.
Charger Location
• IMPORTANT: Only use the unit on a flat, level surface to avoid movement during operation. If it
must be used on a slanting or uneven surface, take proper precautions to secure the wheels to avoid
shifting or movement before use.
• Locate charger as far away from battery as cables permit.
• Never place charger directly above battery being charged; gases from battery will corrode and damage
charger.
• Never allow battery acid to drip on charger when reading gravity or filling battery.
• Never operate charger in a closed-in area or restrict ventilation in any way.
• Marine batteries must be removed and charged on shore.
• Do not set a battery on top of charger.
Connection Precautions
• Connect and disconnect output clamps only after removing AC cord from electric outlet.
• Never allow clamps to touch each other.
• Attach clamps to battery and chassis as indicated in “Battery Installed in Vehicle” steps 5 and 6, or in
“Battery Outside of Vehicle” steps 2 to 5.
Follow these steps when the battery is installed in a vehicle
• WARNING: A spark near the battery may cause an explosion. To reduce risk of a spark near the
battery:
1. Position AC and clamp cords to reduce risk of damage by hood, door, or moving engine part.
2. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
3. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger diameter than
NEGATIVE (NEG, N, –) post.
4. Determine which post of battery is grounded (connected) to the chassis. If negative post is grounded
to chassis (as in most vehicles), see 5. If positive post is grounded to the chassis, see 6.
5. 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. Do not connect clip to carburetor, fuel lines, or sheet-metal body
parts. Connect to heavy gauge metal part of the frame or engine block.
6. 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. Do not connect clip to carburetor, fuel lines or sheet-metal body parts.
Connect to a heavy gauge metal part of the frame or engine block.
7. When disconnecting charger, disconnect AC cord, remove clamp from vehicle chassis, and then
remove clamp from battery terminal.
8. Do not charge the battery while the engine is operating.
9. See operating instructions for length of charge information.
Follow these steps when the battery has been removed from a vehicle
• WARNING: A spark near the battery may cause an explosion. To reduce risk of a spark near the
battery:
1. Check polarity of battery posts. The Positive post (marked POS,P, +) usually has a larger diameter
than the Negative battery post (marked NEG, N, –).
2. Attach a 24-inch (minimum length) AWG #6 insulated battery cable to the Negative battery post
(marked NEG, N, –).
