If not possible, the rod must be completely retracted or it must be greased instead For high-pressure cleaning or blasting on the cylinder, the rod and the oil-ports must be suitably protected For double-acting cylinders working as single acting, we recommend to connect the non-used oil-port to tank In case you need to dismount the cylinder, please note that the piston is screwed onto the rod end and fixed with industrial glue, so you must use also industrial glue when mounting again
