Panasonic EY7442 Operating Instructions Manual page 10

(1) LED light
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 reg-
ular 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.
(2) Overheat warning lamp
Off
(normal
operation)
Indicates operation has
been halted due to motor
or battery overheating.
To protect the motor or battery, be
sure to note the following when car-
rying out this operation.
• If the motor or battery becomes hot,
the protection function will be acti-
vated and the motor or battery will
stop operating. The overheat warn-
ing lamp on the control panel illumi-
nates or flashes when this feature is
active.
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 affect the
performance of the tool
during use or its battery
capacity.

• If the overheating protection feature
activates, allow the tool to cool tho-
roughly (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
under high-load conditions or if it is
used in hot-temperature conditions
(such as during summer), the over-
heating protection feature may acti-
vate 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.
(3) Battery low warning lamp
Off
(normal
operation)
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 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.
