5. When in any of the conditions that
battery pack is too cool, or the bat-
tery pack has not been used for a
long time, the charging lamp is lit. In
this case, charging takes longer to
fully charge the battery pack, than
the standard charging time.
If a fully charged battery pack is
inserted into the charger again,
the charging lamp light up. After
several minutes, the charging
lamp may flash quickly to indicate
the charging is completed.
6. If the charging lamp does not light
immediately after the charger is
plugged in, or if after the standard
charging time the lamp does not go
off, consult an authorized dealer.
NOTE:
When charging a cool battery pack
(below 5°C (41°F)) in a warm place,
leave the battery pack at the place
and wait for more than one hour to
warm up the battery to the level of
the ambient temperature. Other-
wise battery pack may not be fully
charged.
Cool down the charger when charg-
ing more than two battery packs
consecutively.
Do not insert your fingers into con-
tact hole, when holding charger or
any other occasions.
CAUTION:
Do not use power source from an
engine generator.
Do not cover vent holes on the
charger and the battery pack.

Factors Affecting Tightening Torque
Factors Affecting Tightening Torque
The tightening torque is affected by a wide variety of factors including the follow-
ings. After tightening, always check the torque with a torque wrench.
1)
Voltage
When the battery pack becomes nearly discharged, the voltage decreases and
the tightening torque drops.
