Mentioned previously that my 4" extended Eastwood air grinder had no power. Bought it 16 months ago but just dug it out to work on my trailer - so technically it was off warranty. Tried everything, differences hoses, lengths, fitting, air oil etc ,just shut down with the slightest disc pressure. Contacted Eastwood and explained my situation...they replied with an RMA number so it could be replaced
Eastwood is OK and the lady I dealt with was very pleasant also.
