USER’S MANUAL
2. PERSONAL PRECAUTIONS
(CONTINUED)
2.8 When working with a lead-acid battery, remove personal metal items such as rings, bracelets, necklaces, watches, etc.
A lead-acid battery can produce a short-circuit current high enough to weld a ring or the like to metal, causing a severe burn.
2.9 Use charger for charging a 12 Volt Lead-Acid Battery. The rated capacity of the battery should be 30AH maximum.
The charger can charge LEAD ACID battery only. It is not intended to supply power to a low voltage electrical system other
than in a power supply application. Do not use battery charger for recharging dry-cell or non-rechargeable batteries that are
commonly used with home appliances. These batteries may burst and cause injury to persons and damage to property.
While charging wrong type of battery, it will cause battery serious damage.
2.10
NEVER charge a frozen battery.
2.11
NEVER charge the wrong type of battery.
2.12
NEVER charge the wrong voltage of battery.
3. PREPARING TO CHARGE
3.1 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. Be sure area around battery is well ventilated
while battery is being charged. Gas can be forcefully blown away by using a piece of cardboard or other non-metallic
material as a fan.
3.2 Clean battery terminals. Be careful to keep corrosion from coming into contact with eyes. 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 caps, carefully follow manufacturer's recharging instructions.
3.3 Study all battery manufacturers’ specific precautions such as removing or not removing cell caps while charging and
recommended rates of charge.
3.4 Determine voltage of battery by contacting battery manufacturer and make sure it matches output rating of battery charger.
4. CHARGER LOCATION
4.1 Locate charger as far away from battery as dc cables permit.
4.2 Never place charger directly above battery being charged; gases from battery will corrode and damage charger.
4.3 Never allow battery acid to drip on charger when reading gravity or filling battery.
4.4 Do not operate charger in a closed-in area or restrict ventilation in any way.
4.5 Do not set a battery on top of charger.
5. DC CONNECTION PRECAUTIONS
5.1 Connect and disconnect DC output terminals only after removing charger from AC outlet.
5.2 Never allow DC output terminals to touch each other.
5.3 If problems arise connecting the output leads, solicit the aid of your Dealer from whom you purchased this product
or the charger manufacturer for finding a suitable connection device for your application.
Attach clips to battery and chassis as indicated in 6.5 through 6.7 and 7.2 through 7.4
6. 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:
6.1 Position AC and DC cords to reduce risk of damage by hood, door or moving engine part.
6.2 Stay clear of fan blades, belts, pulleys, and any other parts that can cause injury to persons.
6.3 Check polarity of battery posts POSITIVE (POS., P, +) post usually has larger diameter than NEGATIVE - (NEG., N, -).
6.4 Determine which post of battery is grounded (connected) to chassis. If negative post is grounded (as in most vehicles),
see paragraph 6.5 If positive post is grounded, see paragraph 6.6.
6.5 For negative-grounded vehicle, first connect POSITIVE (RED) clip from charger to POSITIVE (POS., P, +) ungrounded post
of battery. Then connect NEGATIVE (BLACK) terminal to vehicle chassis or engine block away from battery.
6.6 For positive-grounded vehicle, connect NEGATIVE (BLACK) clip from charger to NEGATIVE (NEG., N, -) ungrounded post
of battery. Connect POSITIVE (RED) clip to vehicle chassis or engine block away from battery keeping the battery terminal
well removed there from.
6.7 Do not connect any charger clips to carburetor, fuel lines, or sheet-metal body parts.
Connect to a heavy gauge metal part of the frame or engine block.
