Using The Sight Light
Before operation, the Sight Light will
be activated when the On/Off switch is
slightly depressed, and will automatically
turn off 20 seconds after the On/Off
switch is released.
The tool and battery are equipped with a
protection system to extend battery life.
The Sight Light will flash a warning for
3 seconds, then the tool will stop. The
automatic protection system stops the
tool during the following conditions:
• Overloaded:
The tool is operated in
a manner that causes it to draw an
abnormally high current. In this situation,
release the Switch and stop the
application that caused the overload. Pull
the Switch again to restart.
• Overheated:
Under the condition above,
if the tool does not start, the Tool and
Battery are overheated. Let the Tool and
Battery cool before pulling the Switch
again.
• Low battery voltage:
The remaining
Battery capacity is too low and the tool
will not operate. Remove and recharge
the Battery.
Warning:
To turn on the Light, press
the On/Off switch and make sure the
Forward/Reverse Rotation Control is on
right/left position.
