(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
(motor)
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 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 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.
(3) Battery low warning lamp
Excessive (complete) discharging of
lithium ion batteries shortens their service
life dramatically. The driver includes a
battery protection feature designed to
prevent excessive discharging of the
battery pack.
The battery protection feature activates
● ●
immediately before the battery loses its
charge, causing the battery low warning
lamp to flash.
If you notice the battery low warning
● ●
lamp flashing, charge the battery pack
immediately.
