Flashing: Overheat
Indicates operation has
been halted due to motor
or battery overheating.
The overheating protection feature halts
driver operation to protect the motor and
battery pack in the event of overheating.
The overheat warning lamp on the control
panel flashes when this feature is active.
• If the overheating protection feature acti-
vates, allow the driver to cool thoroughly
(at least 30 minutes). The driver is ready
for use when the overheat warning lamp
goes out.
• Avoid using the driver in a way that
causes the overheating protection fea-
ture to activate repeatedly.

operation)
Flashing (No charge)
Battery protection
feature active
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.
Recommended Grip
Use the grip to hold and operate the
driver with one hand. If the job requires
additional force, you can push against
the rear end of the driver with your other
hand.

ing it.
• The ambient temperature range is
between 0°C (3°F) and 40°C (104°F).

temperature is below 0°C (3°F), the tool
may fail to function properly.
• When battery pack is not in use, keep it
away from other metal objects like: paper
clips, coins, keys, nails, screws, or other
small metal objects that can make a con-
nection from one terminal to another.
Shorting the battery terminals together
may cause sparks, burns or a fire.
• When operating the battery pack, make
sure the work place is well ventilated.
• When the battery pack is removed from
the main body of the tool, replace the
battery pack cover immediately in order
to prevent dust or dirt from contaminating
the battery terminals and causing a short
circuit.
Battery Pack Life

ited life. If the operation time becomes
extremely short after recharging, replace
the battery pack with a new one.
