(1) LED light
CAUTION:
• The built-in LED light is designed to
illuminate the small work area tempo-
rarily.
• 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 perfor-
mance of procedures other than those
specifi ed herein may result in hazardous
radiation exposure.

Overheat
(battery)
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 acti-
vated 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 thor-
oughly (at least 30 minutes). The
tool is ready for use when the over-
heat 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 un-
der high-load conditions or if it is used
in hot-temperature conditions (such as
during summer), the over-heating pro-
tection feature may activate frequently.
• If the tool is used in cold-tempera-
ture conditions (such as during win-
ter) or if it is frequently stopped dur-
ing use, the overheating protection
feature may not activate.
(3) Battery low warning lamp
Off
(normal
operation)
Excessive (complete) discharging of
lithium ion batteries shortens their
service life dramatically. The driver
includes a battery protection feature
designed to prevent excessive dis-
charging of the battery pack.
• The battery protection feature ac-
tivates immediately before the bat-
tery 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.
