: Hold the head in the concrete for roughly 5–15 seconds until the surface around the poker becomes shiny and air bubbles stop rising.

: Always wash the poker head and the rubber-coated shaft with water immediately after use. Once concrete hardens on the equipment, it is difficult to remove and can cause overheating.

: Connect the flexible shaft to the drive unit (vibrator motor). Ensure the coupling is secure and locked. The shaft is typically 4 meters long, allowing for significant reach.
