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.

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

To protect the motor or battery, be sure to note the following when carrying out this operation.

●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

a c t i v a t e s , a l l o w t h e t o o l t o c o o l 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.

The performance of the EY9L42 de- teriorates significantly at and below 10°C due to work conditions and other factors.

●The ambient temperature range is between 0°C (32°F) and 40°C (104°F).

If the battery pack is used when the battery temperature is below 0°C (32°F), the tool may fail to function properly.

●When charging a cool battery pack (below 0°C (32°F)) in a warm place, leave the battery pack at the place and wait for more than one hour to warm up the battery to the level of the ambient temperature.
