TEMPERATURE INDICATOR LIGHT The red indicator light signals whether the battery or tool (with battery inserted) is in the optimum temperature range. When the temperature is too high, the tool will not operate at full capacity. If the red indicator light illuminates continuously when the battery is inserted into the charger. The battery is outside the charging temperature range and cannot be charged. If the red indicator light blinks when the button or on/off switch (with battery inserted) is pressed, the battery is outside the operating range of -10 ˚C to +60 ˚C. When the temperature is above 70 ˚C the battery turns off until it's in the optimum temperature range. INSERTING AND RELEASING BATTERY PACK Set Forward/Reversing lever to the center (off position). Slide charged battery pack into the housing until the battery pack locks into position and the red warning label is no longer visible (Fig. 1). Your battery pack is equipped with a secondary locking latch to prevent the battery pack from completely falling out of the handle, should it become loose due to vibration.

CHARGER 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. If the green indicator light is "BLINKING", the battery pack is being fast-charged. Fastcharging 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 automatically switch to fastcharging once a suitable temperature is reached. If the red indicator light is "BLINKING", 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 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. 2. 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. 3. Remember to unplug charger during storage period. -11-
