A. IMPORTANT SAFETY INSTRUCTIONS
1. SAVE THESE INSTRUCTIONS -This manual contains
important safety and operating instructions for battery charger Model SE-1072.
A BATTERY CHARGER RECEIVES AC POWER FROM THE ELECTRIC OUTLET, AND
DELIVERS DC CURRENT TO THE BATTERY.
2. Before using battery charger, read all instructions and cautionary markings on (1)
battery charger, (2) battery, and (3) product using battery.
3. CAUTION - To reduce risk of injury, charge only lead acid type rechargeable batteries.
Other types of batteries may burst, causing personal Injury and damage.
4. Use of an attachment not recommended or sold by the battery charger manufacturer
may result in a risk of fire, electric shock, or injury to persons.
5. To reduce risk of damage to electric plug and cord, pull by plug rather than cord when
disconnecting charger.
6. Make sure cord is located so that it will not be stepped on, tripped over, or otherwise
subjected to damage or stress.
7. An extension cord should not be used unless absolutely necessary. Use of improper
extension cord could result in a risk of fire and electric shock. If extension cord must be
used, make sure:
(a) That pins on plug of extension cord are the same number, size and shape as those
of plug on charger;
(b) That extension cord is properly wired and In good electrical condition; and
