• When you charge a new battery cartridge or a battery
cartridge which has not been used for a long period of
time, it may not accept a full charge. This is a normal
condition and does not indicate a problem. You can
recharge the battery cartridge fully after discharging it
completely and recharging a couple of times.
• When you charge a battery cartridge from a just
operated tool or a battery cartridge which has been left
in a location exposed to direct sunlight or heat for a long
time, let it cool off. Then re-insert it and try to charge it
once more.
• When you charge a battery cartridge which has not been
used for a long period, sometimes the charging light will
go out soon. If this occurs, remove the battery cartridge
and re-insert it. If the charging light goes out within one
minute even after repeating this procedure a couple of
times, the battery cartridge is dead. Replace it with a
new one.
Trickle charge (Maintenance charge)
If you leave the battery cartridge in the charger to prevent
spontaneous discharging after full charge, the charger will
switch into its “trickle charge (maintenance charge)” mode
and keep the battery cartridge fresh and fully charged.
Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely dis-
charged.
Always stop tool operation and charge the battery car-
tridge when you notice less tool power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room temperature at
10°C - 40°C (50°F - 104°F).
Let a hot battery cartridge cool down before charging it.

CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the switch trigger actuates
properly and returns to the “OFF” position when
released.
