(2) LED light

Before the use of LED

light, always pull the

power switch once.

Press the LED light

on button.

The light illuminates

with very low cur-

rent, 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 illu-

minate 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.

panel flashes when this feature is active.

• If the overheating protection feature acti-

vates, allow the driver to cool thoroughly

(at least 30 minutes). The driver is ready

for use when the overheat warning lamp

goes out.

• Avoid using the driver in a way that

causes the overheating protection fea-

ture to activate repeatedly.

dramatically. The driver includes a battery

protection feature designed to prevent

excessive discharging of the battery pack.

• The battery protection feature activates

immediately 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.
