OPERATING INSTRUCTIONS

NOTE: Before using the tool, read the instruction
book carefully.
1. BEFORE USING YOUR CORDLESS DRILL
Your battery pack is UNCHARGED and you must
charge once before use. Your battery pack will not be
fully charged until you have performed several charge
and discharge operations by charging & working with
your drill. After this your battery pack performance will
improve.
Warning:The charger and battery pack are specif-
ically designed to work together so do not attempt
to use any other devices. Never insert or allow metallic
objects into your charger or battery pack connections be-
cause an electrical failure and hazard will occur.
2. HOW TO CHARGE YOUR BATTERY PACK (See
Fig 1)
1) Connect the battery charger to the power supply. The
red light will illuminate for 3 seconds and then it will go
out.
Note: If the red light flashes at a rapid rate (approx. 5
flashes per second), this means that the charger has
failed and must be replaced.
2) Fully insert the battery pack into the charger. With
a normal charging process, only the red light will illu-
minate to show charging has started. The red light will
remain on during the charging process. A discharged
battery at normal ambient temperature will take approx-
imately 1 hour to reach full charge.
Note: If the battery temperature is lower than 36ºF (0ºC),
the green light will flash slowly (approximately 2 flashes
per second). Remove the battery and allow the battery
to warm-up to a charging temperature between 36ºF to
95ºF (2ºC and 35ºC).
If the battery temperature is over 140ºF (60ºC), the green
light will flash rapidly (approximately 5 flashes per sec-
ond). Remove the battery and allow the battery to cool-
down to a charging temperature between 36ºF to 95ºF
(2ºC and 35ºC).
If the battery temperature is over 176ºF (80ºC), the charg-
ing process will be stopped, and the red light will flash
with a low speed (approximately 2 flashes per second).
The battery must be replaced.
3) When the charging is complete, only the green light
will illuminate.
Note: When the battery is under charging and its volt-
age cannot reach 4V in 2 minutes, we consider the bat-
