› If the ring securing the bit is
damaged, the bit may come off during
use causing personal injury.
› The torque delivered by the drill
driver depends on how long it is
applied, the size of bit and other
factors such as the state of the battery
charge.

the direction of rotation. Always
release the trigger switch and wait for
the drill driver to stop before switching
the direction of rotation.

LITHIUM-ION BATTERY &
CHARGER SAFETY
OVER CHARGING PROTECTION
This feature ensures that the battery is
never overcharged. When the battery
has reached its full charge capacity
the charger will shut off protecting the
internal components of the battery
from being damaged.

OVER DISCHARGE PROTECTION

An internal component of the
battery pack is an over discharge
protector. This feature will stop the
battery from discharging beyond the
recommended lowest safety voltage.
OVER HEAT PROTECTION
The battery has an internal Thermister
cut off sensor which will cease the
charging cycle if the battery becomes
hot during the charging process. This
Thermister sensor will also stop the
battery from operating should the
battery become too hot during the
operation of the tool. This can happen
when the tool is overloaded or being
used for extended periods of time.
Up to 30min in cooling time may
be required depending on ambient
temperature and operation being
performed.
OVER CURRENT PROTECTION
Should the battery be overloaded
and the maximum current draw be
exceeded the battery will temporarily
stop working to protect the internal
components. The battery will resume
to normal operation once the
excessive current draw has returned
to normal safe level. This may take a
few seconds.
