Precision Drive (Fig. 8)
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 work piece, and then (if required) start
a slow controlled impact to ensure the head ends perfectly flush.
This mode is for light duty screwdriving applications. If the
NOTE:
