CAUTION:
• The built-in LED light is designed to
illuminate the small work area tem-
porarily.
• Do not use it as a substitute for a
regular flashlight, since it does not
have enough brightness.
• LED light turn 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 specifi ed herein
may result in hazardous radiation exposure.
(2) Overheat warning lamp
Off
(normal
operation)
Illuminated:
Overheat
(motor)
Flashing:
Overheat
(battery)
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
activates, allow the tool to cool
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 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.
• The performance of the EY9L42
deteriorates significantly at and below
10°C due to work conditions and
other factors.
(3) Battery low warning lamp
Off
(normal
operation)
Flashing
(No charge)
Battery protection
feature active
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 acti-
vates 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.
• If it is started with too little battery
power remaining, the tool may stop
operating without the battery low
warning lamp flashing first. This
