Gweithrediad Sbardun
The tool features a variable-speed metal trigger. The speed of the ratchet is controlled by how far the trigger is depressed. Pressing the trigger lightly will result in slower speeds, while fully depressing it will achieve maximum RPM.

The REDLINK™ Intelligence system protects the tool from overloading. If the tool stops unexpectedly, release the trigger, allow it to cool, and then resume operation.
