IMPORTANT SAFETY INFORMATION, SAVE THESE
TO REDUCE THE RISK OF INJURY, USER MUST READ AND UNDERSTAND
THIS INSTRUCTIONAL MANUAL. THIS MANUAL CONTAINS IMPORTANT
INFORMATION REGARDING THE OPERATION AND WARRANTY OF THIS
PRODUCT. PLEASE RETAIN FOR FUTURE REFERENCE.
I M P O RTANT SAFETY INSTRUCTIONS
1. RISK OF EXPLOSIVE GAS MIXTURES — WORKING IN VICINITY OF A LEAD-
ACID BATTERY IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES
DURING NORMAL 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.
2 . To reduce risk of battery explosion, follow these instructions and those published
by the battery manufacturer and manufacturer of any equipment you intend to use
in vicinity of battery. Review cautionary markings on these products and on
e n g i n e .
3 . This equipment employs parts (switches, relays, etc.) that produce arcs or sparks.
Therefore, if used in a garage or enclosed area, the unit MUST be placed not less
than 18 inches above the floor.
1. Use of an attachment not recommended or sold by the battery charger manufacturer
may result in a risk of fire, electric shock, or injury to persons.
2. To reduce risk of damage to electric plug and cord, pull by plug rather than cord when
3. An extension cord should not be used unless absolutely necessary. Use of an improper
extension cord could result in a risk of fire and electric shock, and will void warranty.
If an extension cord must be used, make sure:
a. that pins on plug of extension cord are the same number, size, and shape as those
of plug on charger;
b. that extension cord is properly wired and in good electrical condition; and
c. that wire size is AWG#16 (16 gauge) for 100 feet and AWG#14 for distances over
4. Do not operate charger with damaged cord or plug — take to a qualified technician for
replacement of the plug or cord immediately.
5. Do not operate charger if it has received a sharp blow, been dropped, or otherwise
damaged in any way; take it to a qualified service technician.
6. Do not disassemble charger; take it to a qualified service technician when service or
repair is required. Incorrect re-assembly may result in a risk of electric shock or fire,
and will void warranty.
7. To reduce risk of electric shock, unplug charger from outlet before attempting any
maintenance or cleaning. Turning off controls without unplugging will not reduce this
8. Do not expose charger to rain, snow or use when wet.
1. Another person should be within range of your voice or close enough to come to your
aid when you work near a lead-acid battery.
2. Fresh water and soap should be nearby in case battery acid contacts skin, clothing, or
3. Wear complete eye protection and clothing protection. Avoid touching eyes while
working with a battery. Acid, acid particles or corrosion may get into eyes. Immediately
flood eye with cold water (Eye Wash Station) for at least 15 minutes and seek medical
4. If battery acid contacts skin or clothing, wash immediately with soap and water. If
redness, pain or irritation occurs, seek immediate medical attention.
NEVER smoke or allow a spark or flame in vicinity of battery or engine.
6. Be extra cautious to reduce the risk of dropping a metal tool onto battery. This might
cause sparks or short-circuit the battery or other electrical part, which can cause an
7. Remove personal metal items such as rings, bracelets, necklaces and watches when
working with a lead-acid battery. A lead-acid battery can produce a short-circuit current
high enough to cause a severe burn.
8. Use charger for charging a LEAD-ACID battery only. It is not intended to supply power
to a low-voltage electrical system other than in a starter-motor application. Do not use
the battery charger for charging dry-cell batteries that are commonly used with home
appliances. These batteries may burst and cause injury to persons and damage
9. NEVER ATTEMPT TO CHARGE A FROZEN BATTERY.
Power Cord Safety
This appliance has a polarized plug (one blade is wider than the other) as a safety feature.
This plug will fit into a polarized outlet only one way. If the plug does not fit fully into the outlet,
reverse the plug. If it still does not fit, contact a qualified electrician. Do not attempt to defeat
this safety feature.
Preparing to Charge
1. Determine voltage of battery to be charged by referring to the vehicle manual.
2. 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.
3. Clean battery terminals. Do not allow corrosion to come in contact with eyes.
4. 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
5. Study all battery manufacturer's specific precautions, such as removing or not
removing cell caps while charging, and recommended rates of charge.
6. Area around battery should be well ventilated while battery is being charged. Gas can
be forcefully blown away by using a piece of cardboard or other nonmetallic material
as a fan.
7. Make sure the initial charging rate does not exceed battery manufacturer's
1. Locate charger as far away from battery as cables permit.
2. NEVER place charger directly above battery being charged; gases from battery will
corrode and damage charger.
3. NEVER allow battery acid to drip on charger when reading gravity or filling battery.
4. NEVER operate charger in a closed-in area or restrict ventilation in any way.
5. Marine batteries must be removed and charged on shore.
6. Do not set a battery on top of charger.
DC Connection Precautions
1. Connect and disconnect DC output clamps only after removing AC cord from electric
2. Never allow clamps to touch each other.
3. Attach clamps to battery chassis as indicated in "Battery Installed in Vehicle" steps 5
and 6, and in "Battery Outside of Vehicle" steps 2, 4 and 5.
Follow these steps when the battery is installed in a vehicle. A spark near the battery
may cause an explosion. To reduce risk of a spark near the battery:
1. Position AC and DC cords to reduce risk of damage by hood, door, or moving engine
2. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to
3. Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has larger
diameter than NEGATIVE (NEG, N, –) post.
