temporarily.
•
Do not use it as a substitute for a
regular flashlight, since it does not
have enough brightness.

Flashing:
Overheat
Indicates operation has
been halted due to battery
overheating.
To protect the motor or battery, be sure
to note the following when carrying 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 cau
-
ses 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
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 overheating 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.
• When charging a cool battery pack
(below 0°C (32°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.
(3) Battery low warning lamp
