When using an extension cord, make sure:
1. That pins on the extension cord plug are the same number, size and shape as those of the
charger’s plug;
2. That extension cord meets UL (Underwriters Laboratories, Inc.) acceptance and is in proper
operating condition;
3. That wire size is large enough for the ac ampere rating of charger.
Do not operate charger with a damaged cord or plug—replace the cord or plug immediately.
Do not operate charger if it has received a sharp blow, been dropped or otherwise damaged in any way;
contact our technical support group for assistance (800.742.2740).
Do not disassemble charger; contact technical support when service or repair is required. Incorrect
reassembly may result in risk of electrical shock or fire.
To reduce risk of electrical shock, unplug charger from outlet before attempting any maintenance or
cleaning.
WARNING: RISK OF EXPLOSIVE GASES
1. 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 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 by the manufacturer of any equipment you intend to use in the vicinity of
battery. Review all cautionary markings on any product being utilized in or around the charging
device.
PERSONAL PRECAUTIONS
Someone should be within range of your voice or close enough to come to your aid when you work near a
lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, eyes, or other
surfaces.
Wear complete eye protection and clothing protection. Avoid touching eyes while working near battery.
If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye,
immediately flood eye with running cold water for at least 10 minutes and seek medical attention.
NEVER smoke or allow a spark or flame in the vicinity of a battery or engine.
Be extra cautious to reduce risk of dropping a metal tool onto battery. This might cause a spark or short-
circuit a battery, possibly resulting in an explosion.
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, to metal, causing a severe burn.
Use charger for charging a LEAD-ACID (lead acid, sealed lead acid, gel cell, and AGM) 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 battery charger for charging dry-cell batteries that are commonly used with home appliances.
These dry cell batteries may explode, causing personal injury and damage to property.
