I have a Makita Chain Mortiser with an 18mm chain. Last night, I hit a piece of barb wire that was embedded in a timber and broke off five teeth. I have a guy that can sharpen the chain, but he can't replace the broken teeth. They are all missing from one row on the forward surface of the chain. If I don't replace them, I can't use this chain any longer. I called Makita to buy links and pins. They told me that will not sell any pieces for the chain, nor will they offer any type of repair service. What's the deal here? They are basically saying that this chain is a throwaway item? I don't understand why I can get links for a twenty dollar Oregon brand chainsaw chain, but not for a $250 chain.

Does anyone know of a place where I can get this chain serviced? Any help will be greatly appreciated.
