of rotation, you may hear a click on start up. This is normal and
does not indicate a problem.

of the tool using the variable speed trigger
Scaffolding Mode (Fig. C)
DCF921
Your tool is equipped with a mode designed for scaffolding
applications. In forwards rotation it will run down the nut on
the scaffold clamp and then impact for a period of time before
cutting off to avoid over tightening of the fastener. In reverse
rotation it will impact to break the nut free, before winding
down the nut and cutting off after a period of time to limit
damage to clamps.
nOTE: Always check scaffolding clamps are tightened correctly
with a torque wrench.
Timber Screw™ Mode (Fig. C)
DCF922, DCF923
Timber Screw™ mode optimises tool performance to help
increase the speed of fastening applications in wood using lag
bolts, lag screws and structural wood screws.
Precision Wrench™ Mode (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 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 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.
