(2) Overheat warning lamp
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
activated 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
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
overheating protection 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.
(3) Battery low warning lamp
Excessive (complete) discharging of
lithium ion batteries shortens their
service life dramatically. The driver
includes a battery protection feature
designed to prevent excessive
discharging of the battery pack.
• The battery protection feature
activates 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.
