Level the base by adjusting the four leveling feet until the bubble in the level indicator (located at the rear of the base) is centered.
A wrench may be needed to loosen the locking nut above each leveling foot. When the base is level, retighten the locking nuts
up against the base to lock each foot into place.
Note: Ensure that the base is level each time its location is changed.
