Precision Wrench™ (Fig. D)
In addition to normal 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 at 1200 RPM until impact begins.
The tool will then pause for 0.75 seconds before continuing
to impact at a rate of 1890 IPM, 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 and
rate of 1890 IPM. 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.
