Mode Selector (Fig. A, D)
Your tool is equipped with a mode selector
you to select one of two speeds, Timber Screw™ mode, or
Precision Wrench™ mode. Select the mode based on the
maximum speed/torque needed and control the speed of
the tool using the variable speed trigger switch
Timber Screw™ Mode (Fig. D)
Timber Screw™ mode optimizes tool performance to help
increase the speed of wood driving applications such as with
lag bolts, lag screws and structural wood screws.
Precision Wrench™ Mode (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 2500 RPM until
impact begins. The tool will then pause for 0.5 seconds
before continuing to impact at a rate of 3550 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
3 . Press
and rate of 3550 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.
