feature a c t i v a t e s , a l l o w t h e
t o o l t o c o o l thoroughly (at
least 30 minutes). The tool is
ready for use when the overheat
warning lamp goes out.
Avoid using the tool in a way that
●
causes the overheating protec-
tion feature to activate repeatedly.
If the tool is operated continuously
●
under high-load conditions or if it is
used in hot-temperature conditions
(such as during summer), the
overheating protection feature may
activate frequently.
If the tool is used in cold-
●
temperature conditions (such as
during winter) or if it is frequently
stopped during use, the overheat-
ing protection feature may not
activate.
The performance of the EY9L42
●
deteriorates significantly at and
below 10°C due to work conditions
and other factors.
The ambient temperature range is
●
between 0°C (32°F) and 40°C
(104°F). If the battery pack is used
when the battery temperature is
below 0°C (32°F), the tool may fail
to function properly.
Use the charger at temperatures
●
between 0°C and 40°C, and
charge the battery at a tempera-
ture similar to that of the battery
itself. (There should be no more
than a 15°C difference between
the temperatures of the battery
and the charging location.)

operation)
Excessive (complete) discharging of
lithium ion batteries shortens their
service life dramatically. The driver
includes a battery protection feature
designed to prevent excessive dis-
charging of the battery pack.
The battery protection feature ac-

tivates
battery loses its charge, causing
the battery low warning lamp to
flash.
If you notice the battery low warn-
•
ing lamp flashing, charge the bat-
tery pack immediately.
If it is started with too little battery
•
power remaining, the tool may stop
operating without the battery low
warning lamp flashing first. This
indicates that there is too little bat-
tery power remaining to use the
tool, and the battery pack should
be charged before further use.
If the tool is subject to a sudden
•
load during use that causes the
motor to lock up, the overdischarge
prevention sensor may be trig-
gered, and the battery low warning
lamp may flash. The lamp will stop
flashing once you address the
cause of the motor's locking up and
cycle the trigger.
The battery protection feature may
•
activate when a high load is ab-
ruptly placed on the motor, even if
ample battery charge remains. In
this case, both the battery low
warning lamp and LED light will
flash. (EY78A1)
