LED FUNCTIONS OF CHARGER

See Figure 6.

LED WILL BE ON TO INDICATE STATUS OF CHARGER AND BATTERY PACK:

Red LED on = Fast charging mode.

Green LED on = Fully charged battery pack.

Yellow and Green LEDs on = Control charge or defective battery pack.

No LED on = Defective charger or battery pack.

CAUTION:

To prevent damage to battery pack, remove battery pack from charger immediately if no LED comes on. Return battery pack and charger to your nearest Homelite Authorized Service Center for checking or replacing. Also, if you are remov- ing battery pack from charger and no LEDs are on, return both battery pack and charger to your nearest Homelite Authorized Service Center. Do not insert another battery pack into charger. A damaged charger may damage a battery pack.

CHARGING YOUR BATTERY PACK

The battery pack for this unit has been shipped in a low charge condition to prevent possible problems. Therefore, you should charge it prior to use.

NOTE: Batteries will not reach full charge the first time they are charged. Allow several cycles (trimming followed by recharging) for them to fully charge.

TO CHARGE

• Charge battery pack only with the charger pro-

vided.

Normally, the yellow and green lights on the charger will come on. This indicates charger is in control charge mode and should switch to fast charge mode within 5 minutes. When charger is in fast charge mode the yellow and green lights will go off and the red light will come on. If after a period of 15 minutes the yellow and green lights remain on, remove the battery pack, wait 1 minute and reinsert battery pack in charger. If the yellow and green lights continue to remain on an additional 15 minutes, the battery pack is damaged and will not accept charge.

When your battery pack becomes fully charged, the red light will turn off and the green light will turn on.

After normal usage, 1 hour of charge time is required to be fully charged. A minimum charge time of 1 to 1-1/2 hours is required to recharge a completely discharged battery pack.

The battery pack will become slightly warm to the touch while charging. This is normal and does not indicate a problem.

DO NOT place charger in an area of extreme heat or cold. It will work best at normal room tempera- ture.
