I've recently seen an alarming number of cases where Ego owners have been using grease to lubricate their rammers, causing a build up of grease in their QEVs which consequently leads them to believe that either their QEVs or solenoids are faulty.
If you know of anyone using grease to lubricate their rammer, then please set them straight and advise them to use a light oil instead. If you have already used grease then remove your rammer and clean off all of the grease replacing it with a light oil instead.
If you suspect that your QEV is clogged with grease or the diaphragm of your QEV is stuck preventing it from operating properly, then all that you need to do is remove your QEV, strip, clean and replace it onto your rammer housing.
