In addition to normal impacting modes, this tool features
the Precision Drive™ mode which enables greater control
in lighter applications to avoid damage to materials or
fasteners. It is ideal for light applications such as cabinet
hinge screws or machine screws. Precision Drive™ mode will
work as a screwdriver in light applications, before hesitating
as the screw head reaches the workpiece, and then (if
required) start a slow controlled impact to ensure the head
ends perfectly flush.
nOTE: This mode is for light duty screwdriving applications.
If the tool will not drive a fastener in Precision Drive™
mode, please select Lo Mode which will give the additional
power required.
