Not sure if this is the final word, but I did get a response from Grobet. They said ,"We currently have 7 Refurbished 21" Pegas Saws available. These units are out of warranty but may be sent in for parts and repair. They have been refurbished at Grobet."
I asked what they mean by "may be sent in for parts and repair". Their response is "The units will not be covered by any warranty but the parts may be purchased and the repair paid for." So it sounds like if the unit needs to be repaired, you pay for the parts, but the service is free.
I am not sure if I would participate in this offer.
