Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy
enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting
in loss of power and overheating. The following table shows the correct size to use depending on cord length
and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the
heavier the cord.

• 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.

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.
• 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.
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 TO JUMP-START OR 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.
