• 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.

(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 af- fect 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 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 specified herein may result in hazardous radiation exposure.

Indicates operation has been halted due to motor or battery overheating.

• 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.

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.
