Clean it and hug it every day.
Get in touch with their authorized service rep. He will keep it running for years.
I bought mine in 1996. My service man keeps suggesting I may need a new one soon and then he fixes it for less than $200.00.
I really do hug it and pat its side once in a while. It’s a workhorse.
Or I have my staff hug it: Nova gave it the hug tonight.
