Please read this entire manual, including all Safety Cautions and
Warnings before operating this charger. Never leave charger
unattended when in use. Adult supervision required for children
under12 years of age.

SAFETY CAUTIONS & W ARNINGS

1. Never leave the charger unattended when in use.

2. Do not connect the unit to the DC power supply while there is a
battery attached to the unit. You should disconnect the battery first
and then connect the unit to DC power supply.

3. Do not leave the battery inside any product while charging.

4. Place the charger and battery on a solid uncarpeted surface with
good ventilation.

5. Do not charge the battery inside the full-size automobile as
damage to interior can result.

6. Battery damage can occur if the charge current (Amps) rate is set
too high. Different capacity batteries may require a higher or lower
charge rate. Follow the “Notes on Charging Batteries” in addition to
battery manufacturer’s instructions.

7. If the battery or the charger becomes extremely hot, immediately
disconnect the charger from the power source and allow the
battery and charger to cool.

8. The charger is designed to charge 1~8 cells nickel cadmium or
nickel metal hydride batteries. It will also charge Lithium, lead-acid/
gel cell batteries. Because of the volatile nature of Lithium
batteries, great care must be taken when charging these cells. If
improperly or over charged, there is the risk that the battery will
explode or catch fire. Please follow instructions/recommendations
from battery manufacturer when selecting proper charge rate.

9. Discontinue use if charger casing becomes damaged or cracked.

10. Do not use the DC power source of a running full-size automobile
engine.

11. Always disconnect charger from the power source and any battery
when not in use.

12. Adult supervision is recommended for ages 12 and under.

13. If at any time the cooling fan should fail, discontinue use and
return for service.
