Precision Wrench
™
(Fig. C)
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 at 2000 RPM until impact begins.
The tool will then pause for 0.5 seconds before continuing
to impact at a rate of 3250 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
3250 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.
