Just one caveat,
If you're going to use compressed air, be sure to use LOW pressure. If the
piston is crudded in ( technical term), sometime it will take a lot of pressure
to free it. With compressed air this usually results is a high velocity
airborn object, namely the piston. Use with air with caution, hydraulic
extraction is much less hazardous.
