Good Morning Everyone,
Sorry if this is covered anywhere else... I haven't found it anywhere in my searches.
I have a Vac 700 that is getting stiff to plunge for refills. I'm wondering where exactly I should be applying the grease that came with the pen? Do I pull out the plunger, and lubricate the shaft? Do I need to lubricate the o-ring, and if so, how do I go about doing this?
Thanks so much in advance,
