Mode Selector (Fig.A, D)
Your tool is equipped with a mode selector

which allows
you to select one of three speeds or Precision Wrench™
mode. Select the mode based on the maximum speed/
torque needed and control the speed of the tool using the

.
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 1200RPM until
impact begins. The tool will then pause for 0.75 seconds
before continuing to impact at a rate of 1890IPM, providing
the user with greater control and reducing the chance of
overtightening or damagingmaterial.
When set in reverse, the tool will impact at a normal speed
and rate of 1890IPM. Upon sensing that the fastener has
broken free, the tool will cease to impact and will reduce
speed to help prevent “run‑off” of loosehardware.
