DO NOT USE EXTENSION CORDS unless absolutely necessary. Using

an improper extension cord could result in a risk of re and electric

shock and may result in property damage, personal injury or death. If
extension cord must be used, make sure that:

1.) The pins on the extension cord plug have the same number, size,
and shape as those of the AC power cord plug on the charger.

2.) The extension cord is properly wired and is in good electrical
condition.

3.) The wire size is as specied in Table I below:

AWG SIZE OF CORD

Length Of Cord, Feet (m)

*If the input rating of a charger is given in watts rather than amperes, the corresponding ampere

rating is to be determined by dividing the wattage rating by the voltage rating - for example:

1250 watts/125 volts = 10 amperes

CAUTION

Use of an attachment not recommended or sold by the battery

charger manufacturer may result in a risk of re, electric shock, or

injury to persons.

To reduce risk of damage to electric plug and cord, pull by plug
rather than cord when disconnecting charger.

Do not operate charger with 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; take it to a qualied

serviceman.

Do not disassemble charger; take it to a qualied serviceman

when service or repair is required. Incorrect reassembly may

result in a risk of electric shock or re.

To reduce risk of electric shock, unplug charger from outlet
before attempting any maintenance or cleaning. Turning off
controls will not reduce this risk.
