operation)
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.
• 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.
