Before the use of LED light, always pull the
power switch once.
Press the LED light on 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  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
The overheating protection feature halts tool
operation to protect the battery pack in the event
of overheating. The overheat warning lamp on
the control panel 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.
(3) Battery low warning lamp
Excessive (complete) discharging of lithium ion
batteries shortens their service life dra-matically.
The tool includes a battery protec-tion feature
designed to prevent excessive discharging of
the battery pack.
• The battery protection feature activates imme-
diately 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.
