CAUTION
• Keep the protective shoe in contact
with the material being cut while op-
erating the tool.
• Failure to do so may cause the re-
ciprocating saw blade to be dam-
aged due to the resulting vibrations.
• When cutting in a small arc, a lower
feed speed will result.

Battery protection
feature active
Excessive (complete) discharging of
lithium ion batteries shortens their service
life dramatically. The tool includes a
battery protection feature designed to
prevent excessive discharging 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.
• 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 prevention
sensor may be triggered, and the bat-
tery low warning lamp may flash. The
lamp will stop flashing once you ad-
dress the cause of the motor's locking
up and cycle the trigger.

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 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 thor-
oughly (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 fea-
ture to activate repeatedly.
• If the tool is operated continuously un-
der high-load conditions or if it is used
in hot-temperature conditions (such as
during summer), the overheating pro-
tection 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 oth-
er factors.
