feature active
Excessive (complete) discharging of
lithium ion batteries shortens their ser-
vice life dramatically. The tool includes
a battery protection feature designed
to prevent excessive discharging of the
battery pack.
• The battery protection feature acti-
vates immediately before the battery
loses its charge, causing the battery
low warning lamp to flash.
• If you notice the battery low warn-
ing lamp flashing, charge the battery
pack immediately.
- Accidental re-start preventive function
- Even if the battery pack is inserted on
the tool with the power switch in the
“ON” position, the tool does not start.
At this time, the lamp flickers slowly
and this shows that the accidental re-
start preventive function is at work.
- To start the tool, first slide the power
switch toward the “OFF” position and
then slide it toward the “ON” position.
