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 over-
heating protection feature may
activate frequently.
• I f t h e t o o l i s u s e d i n c o l d -
temperature conditions (such as
during winter) or if it is frequently
stopped during use, the overheat-
ing protection feature may not
activate.
• The performance of the EY9L42
deteriorates significantly at and
below 10°C due to work conditions
and other factors.
• 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.
• Use the charger at temperatures
between 0°C and 40°C, and
charge the battery at a tempera-
ture similar to that of the battery
itself. (There should be no more
than a 15°C difference between the
temperatures of the battery and the
charging location.)
