(1) LED light
Before the use of LED
light, always pull the
power switch once.
Press
the LED light
button.
The light illuminates with
very low current, and it does not adversely
affect the performance of the tool during
use or its battery capacity.
CAUTION:
●
The built-in LED light is designed
to illuminate the small work area
temporarily.
●
Do not use it as a substitute for a
regular flashlight, since it does not
have enough brightness.
●
LED light turns off when the tool has
not been used for 5 minutes.
Caution: DO NOT STARE INTO BEAM.
Use of controls or adjustments or
performance of procedures other than
those specified herein may result in
hazardous radiation exposure.
(2) Overheat warning lamp
To protect the motor or battery, be sure to
note the following when carrying out this
operation.
Off
(normal
operation)
Illuminated:
Overheat

Flashing:
Overheat
(battery)
Indicates operation has
been halted due to motor
or battery overheating.
●
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 ashes 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 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 de-
teriorates signicantly 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.
