Dismount the cylinder cover. Drain off cooling water from the cylinder block. Discard the mild steel ring from the top of the cylinder liner. Turn down the piston far enough to make it possible to grind away the wear ridges at the top of the cylinder liner by means of a hand-grinder. Dismount the piston. 2. Disconnect the oil pipes leading from the cylinder lubricator to the non-return valves. Screw off the six non-return valves. Mount the four lifting screws in the cooling jacket.

To make the exercise more challenging, gymnasts will often include variations on a typical circling skill by turning (moores and spindles) or by straddling their legs (Flares). Routines end when the gymnast performs a dismount, either by swinging his body over the horse, or landing after a handstand.
