unless otherwise indicated elsewhere in this instruction manual before further use.
• Do not operate the battery charger near flammable liquids or in gaseous or explosive atmospheres. Motors may spark, and the
sparks might ignite fumes.
WARNING: TO REDUCE THE RISK OF ELECTRIC SHOCK:
• Never immerse the battery charger in water or any other liquid, or use when wet.
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 battery maintainer 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.

WARNING: TO REDUCE THE RISK OF FIRE:
• Do not operate near flammable materials, fumes or gases.
• Do not expose to extreme heat or flames.
• If the vehicle accessory outlet fuse opens (blows) when plugging in this battery charger, do not use this battery charger with this
vehicle accessory outlet:
Do not repeatedly replace the fuse.
Do not replace the vehicle accessory outlet fuse with one of a higher amperage rating.
Never attempt to patch the fuse with tin foil or wire.
Any of these actions may cause serious electrical damage and/or a fire.
CAUTION: TO REDUCE THE RISK OF INJURY OR PROPERTY DAMAGE:
• NEVER ATTEMPT CHARGE A FROZEN BATTERY.

• Do not charge the battery while the engine is operating.
• Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
• Vehicles that have on-board computerized systems may be damaged if vehicle battery is jump-started. Before jump-starting, 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 battery maintainer.
• 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 similar metal object, to skin 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.
• Always turn the battery charger off by unplugging it when not in use.
• DO NOT OPEN THE BATTERY CHARGER — there are no user-serviceable parts inside. Opening the battery charger will void
manufacturer' s warranty.
• Operate battery charger only as described in this Instruction Manual.
• Check battery charger and components periodically for wear and tear. Return to manufacturer for replacement of worn or
defective parts immediately.
Connection precautions
• Connect and disconnect output clamps or vehicle accessory plug only after removing AC cord from electric outlet.
• Never allow clamps to touch each other.
• Attach clamps only as indicated in "Charging Using the Supplied Battery Clips. "
• 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

engine.
INTRODUCTION
Congratulations on purchasing your new battery charger. Read this Instruction Manual and follow the instructions
carefully before using your new battery charger.
OpERATINg INSTRUCTIONS
preparing to Charge
1. Remove battery completely from boat/airplane or any confined area before charging.
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, taking care to avoid getting corrosive material in 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.
Charger Location
• 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.
• Never operate charger in a closed-in area or restrict ventilation in any way.
