Here we have one chair conformation of methylcyclohexane and this is carbon one you can see we have a methyl group that is axial up at carbon one we also have a hydrogen and Ive made the hydrogen green so we can tell apart from the other hydrogens and this hydrogen is equatorial down at carbon one now this chair conformation is in equilibrium with another chair conformation and we can get to the other chair conformation by what we call a ring flip so if I lift this carbon up. I always just draw two slightly angled parallel lines like that.

Up or down doesnt matter on a chair conformation. Carbon atoms of the cyclohexane chair conformers can be designated as UP carbons of the ring or DOWN carbons of the ring. Keep in mind that when the chair is subjected to a ring flip the ethyl group still remains down. You should also take note that substituents that are pointing up A which is axial and C which is equatorial always stay facing up A is up equatorial in the new chair and C is up axial.
