Overheat warning lamp
Flashing: Overheat

(normal Indicates operation has
operation) been halted due to 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 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 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.
• The ambient temperature range is be-
tween 0°C (32°F) and 40°C (104°F). If
the battery pack is used when the bat-
tery 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.

ssive (complete) discharging of li-
Exce
thium ion batteries shortens their ser-
vice life dramatically. The tool includes
a battery protection feature designed to
prevent excessiv
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.
• If it is started with too little battery
power remaining, the tool may stop
operating without the battery low
warning lamp flashing first. This in-
dicates that there is too little battery
power remaining to use the tool, and
the battery pack should be charged
before further use.
• If the tool is subject to a sudden load
during use that causes the motor to
lock up, the overdischarge preven-
tion sensor may be triggered, and
the battery low warning lamp may
flash. The lamp will stop flashing
once you address the cause of the
motor's locking up and cycle the
trigger.
