b) the extension cord is properly wired and in good electrical condition,
c) the wire size is large enough for the AC rating of the charger as indicated in the table in the previous
section.
•Do not operate unit with damaged cord or plug; or if the unit has received a sharp blow, been
dropped, or otherwise damaged in any way. Do not disassemble the unit; return it to the manufacturer
when service or repair is required. Opening the unit may result in a risk of electric shock or fire, and
will void warranty.
•Use of an attachment not supplied, recommended or sold by manufacturer specifically for use with
this unit may result in a risk of electrical shock and injury to persons.
•NEVER submerge this unit in water; do not expose it to rain, snow or use when wet.
•To reduce risk of electric shock, disconnect the unit from any power source before attempting
maintenance or cleaning. Turning off controls without disconnecting will not reduce this risk.
WARNING: RISK OF EXPLOSIVE GASES
•Working in the vicinity of a lead acid battery is dangerous. Batteries generate explosive gases during
normal battery operation. For this reason, it is of the utmost importance that each time before using
the charger you read this manual and follow instructions exactly.
•To reduce the risk of battery explosion, follow these instructions and those published by the battery
manufacturer and manufacturer of any equipment you intend to use in the vicinity of the battery.
Review cautionary markings on these products and on the engine.
•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.
•THIS UNIT IS NOT FOR USE BY CHILDREN AND SHOULD ONLY BE OPERATED BY ADULTS.
CAUTION: TO REDUCE THE RISK OF INJURY OR PROPERTY DAMAGE:
•Pull by plug rather than cord when disconnecting the 120V AC power cord from the unit.
•NEVER ATTEMPT TO CHARGE A FROZEN BATTERY.
•Vehicles that have on-board computerized systems may be damaged if vehicle battery is charged.
Before charging, read the vehicle’s owner’s manual to confirm that external-starting assistance is
suitable.
•When working with lead acid batteries, always make sure immediate assistance is available in case of
accident or emergency.
•Always have protective eyewear when using this product: contact with battery acid may cause
blindness and/or severe burns. Be aware of first aid procedures in case of accidental contact with
battery acid.
•Have plenty of fresh water and soap nearby in case battery acid contacts skin.
•If battery acid contacts skin or clothing, wash immediately with soap and water for at least 10 minutes
and get medical attention immediately.
•Never smoke or allow a spark or flame in vicinity of vehicle battery, engine or charger.
•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 weld a ring, or
the like of a metal, causing a severe burn.
•Never allow battery acid to come in contact with this unit.
•Do not operate this unit in a closed area or restrict ventilation in any way.
•
FIRST AID – SKIN: If battery acid comes in contact with skin, rinse immediately with water, then
wash thoroughly with soap and water. If redness, pain, or irritation occurs, seek immediate medical
attention.
EYES: If battery acid comes in contact with eyes, flush eyes immediately, for a minimum of 15
minutes and seek immediate medical attention.
LCD LIQUID CRYSTAL DISPLAY: If liquid crystal comes in contact with your skin: Wash area off
completely with plenty of water. Remove contaminated clothing. If liquid crystal gets into your eye:
Flush the affected eye with clean water and then seek medical attention. If liquid crystal is swallowed:
Flush your mouth thoroughly with water. Drink large quantities of water and induce vomiting. Then
seek medical attention.
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 instructions.
5. Study all battery manufacturer’s specific precautions, such as removing or not removing cell caps
while charging, and recommended rates of charge.
6. Remove battery completely from boat/airplane or any confined area before charging.
Charger Location
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.
Charger Clamp Connection Precautions
1. Connect and disconnect clamps only after removing AC cord from electric outlet.
2. Never allow clamps to touch each other.
3. Attach clamps to battery and chassis as indicated in “Battery Installed in Vehicle” steps 5 and 6, and
in “Battery Outside of Vehicle” steps 2, 4 and 5.
CAUTION: A spark near the battery may cause an explosion. Follow these steps to reduce the
risk of a spark near the battery when the battery is installed in a vehicle:
1. Position AC and clamp cords away from hood, door, or moving engine parts.
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.
CAUTION: A spark near the battery may cause an explosion. Follow these steps to reduce the
risk of a spark near the battery when the battery has been removed from a vehicle:
1. Check polarity of battery posts. 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) #6 AWG insulated battery cable to the Negative battery post
(marked NEG, N, –).
3. Connect the Positive (RED) battery clamp to the Positive battery post (marked POS, P, + or red).
4. Stand as far back from the battery as possible, and do not face battery when making final connection.
5. Carefully connect the NEGATIVE (BLACK) charger clamp to the free end of the battery cable
connected to the negative terminal.
6. When disconnecting charger, always do so in reverse sequence of connecting procedure and break
first connection while as far away from battery as practical.
Note: A marine (boat) battery must be removed and charged on shore. To charge it on board requires equipment specially
designed for marine use. This unit is NOT designed for such use.
•Check unit periodically for wear and tear. Return to manufacturer for replacement of worn or defective
parts immediately.
•Read and Understand This Instruction Manual Before Using This Unit.
