Not really.
Take the top off, fill it with water, put a fitting in the end then pressurise it to it's test pressure and sit for a minute to check for leaks.
Empty it, turn it upside down on the drier and let sit till it's dry. Whilst it's drying check the head and replace any seals that are/look faulty.
Once dry, fill with powder, screw the head back on and pressurise.
Wouldn't even take an hours worth of labour to do, but you're going to be charged it for an individual extinguisher, as it's typically going to be seen as a low priority to work being carried out for contracted clients.
If God did not intend for us to eat animals, then why did he make them out of meat?
