(3) Battery low warning lamp
Excessive (complete) discharging of
lithium ion batteries shortens their
service life dramatically. The tool
includes a battery protection feature
designed to prevent excessive dis-
charging 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.
• If it is started with too little battery
power remaining, the tool may stop
operating without the battery low
warning lamp flashing first. This
indicates 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 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.
