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.
● 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.
●
The battery protection feature may
activate when a high load is abruptly
placed on the motor, even if ample
battery charge remains. In this case, both
the battery low warning lamp and LED
light will flash (EY74A1).
●
If both the battery low warning lamp and
LED light flash, reduce the force with
which you are pushing on the driver or,
if using a drill driver, adjust the speed
switch to a lower setting (EY74A1).
