CHARGING
〈 UC12SD 〉
Before using the impact wrench, charge the battery as
follows.

until it contacts the bottom of the charger (See Fig. 3).
CAUTION
The UC12SD model is the exclusively designed
charger. This cannot charge batteries except the
specified batteries. It is possible to insert the batteries
other than the specified into the charger and it may
light up the pilot lamps. However, you are requested
to exercise utmost caution not to charge batteries
other than specified ones because these can not only
be charged but also such actions can result in the
malfuntion of chargers.
2. Connect the charger power cord to the receptacle.
Connecting the power cord will turn on the charger
(the pilot lamp lights up).
CAUTION
If the pilot lamp does not light up, pull out the power
cord from the receptacle and check the battery
mounting condition.
