1. Using a wrench, loosen the stopper nut (M12) of each screwjack on the target
router; this allows you to adjust the screwjack.
2. Turn the screwjack counterclockwise until it lifts 10 mm from the floor surface.
3. Fasten again the stopper nut attached to each screwjack.
4. Maintaining the resulting screwjack status, move the router.
5. When you reach the destination, fix the location of the router in the reverse order
of 1–4. Do not attempt to fix the location of the router by locking the casters.
