fect the performance of
the driver during use or its
battery capacity.
CAUTION:
• The built-in LED light is designed to
illuminate the small work area tem-
porarily.
• Do not use it as a substitute for a
regular flashlight, since it does not
have enough brightness.
This product has the built-in LED light.

exposure.
(2) Overheat warning lamp
Off
(normal
operation)
Illuminated:
Overheat
(motor)
Flashing:
Overheat
(battery)
Indicates operation has
been halted due to motor
or battery overheating.
To protect the motor or battery, be
sure to note the following when carry-
ing out this operation.
• If the motor or battery becomes
hot, the protection function will be
activated and the motor or battery
will stop operating. The overheat
warning lamp on the control panel
illuminates or flashes when this
feature is active.
• If the overheating protection feature
activates, allow the tool to cool
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 protection
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 over-
heating 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.)
