When set in forward, the tool will fasten until impact
begins. The tool will then pause for 0.5 seconds before
continuing to impact, 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.
Upon sensing that the fastener has broken free, the tool will
cease to impact and will reduce speed to help prevent “run-
