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 qualied
serviceman.
Do not disassemble charger; take it to a qualied 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.
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 specied in Table I below:
