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.
nOTE: This mode is for light duty screwdriving applications.
If the tool will not drive a fastener in Precision Drive™

In addition to low speed impacting modes, this tool features
the Precision Wrench™ mode which grants the user greater
control in both fastening and loosening applications. When set
in forward, the tool will fasten until impacting begins. The tool
will then pause for 0.5 seconds before continuing to impact,
providing the user with greater control and reducing the chance
of overtightening or damaging material.
When set in reverse, the tool will impact at a normal speed.
Upon sensing that the fastener has broken free, the tool will
cease to impact and will reduce speed to help prevent "run-off"
of loose hardware.
