INDICATORS, SYMBOLS AND MEANING

If the indicator lights are “OFF”, the charger is not receiving power from power supply outlet.

If the green indicator light is “ON”, the charger is plugged in but the battery pack is not inserted, or the battery pack is fully charged and is

being trickle charged.

If the green indicator light is “BLINKING”, the battery pack is being fast-charged. Fast-charging will automatically stop when the

battery pack is fully charged.

If the red indicator light is “ON”, the battery pack is too hot or cold for fast-charging. The charger will switch to trickle charge, until a

suitable temperature is reached, at which time the charger will switch automatically to fast-charging.

If the red indicator light is “BLINKING”, an acoustical signal will sound for a period of 2 seconds which indicates the battery pack

cannot accept a charge or the contacts of the charger or battery pack are contaminated. Clean the contacts of the charger or battery pack only as directed in these operating instructions or those supplied with your tool or battery pack.

IMPORTANT CHARGING NOTES

1.The battery pack accepts only about 80% of its maximum capacity with its first few charge cycles. However, after the first few charge cycles, the battery will charge to full capacity.

2.The charger was designed to fast charge the battery only when the battery temperature is between 32˚F (0˚C) and 140˚F (60˚C). If the battery pack is too hot or too cold, the charger will not fast charge the battery. (This may happen if the battery pack is hot from heavy use). When the battery temperature returns to between 32˚F (0˚C) and 140˚F (60˚C), the charger will automatically begin charging.

3.A substantial drop in operating time per charge may mean that the battery pack is

nearing the end of its life and should be replaced.

4.If you anticipate long periods (i.e. a month or more) of non-use of your tool, it is best to run your tool down until it is fully discharged before storing your battery pack. After a long period of storage, the capacity at first recharge will be lower. Normal capacity will be restored in two or three charge/discharge cycles. Remember to unplug charger during storage period.

5.If battery does not charge properly:

a.Check for voltage at outlet by plugging in some other electrical device.

b.Check to see if outlet is connected to a light switch which turns power “off” when lights are turned off.
