I have a Fein Multimaster that’s about 7-8 years old. No heavy use, just typical home repair/improvement stuff like trimming molding, detail sanding, etc. Probably the most use it’s seen in one session was earlier today when I spent an hour or so with it cutting away the granite top on our kitchen island. (I cut the silicone holding it down, not the granite itself!)

I’m wondering if these tools need any sort of lubrication to keep them in good shape. I don’t see much on the web about disassembling them for greasing, etc., & Fein just says to take it to an authorized service facility.

I guess what I’m most concerned with is the head with the gearbox, eccentric, or whatever is in there doing the oscillating motion.

Anyone with any related experience?

Mine is 16 years old, and I haven’t done a thing. Still works great. The use it’s seen is along the lines you described.

Thanks Fred, that’s good to know. Sounds like I can just blow the dust off & keep using it.

Mine is at least twenty years old and still going strong. I still have the original instruction manual and the only maintenance they suggest is to use a brush to clean out the cooling air slots. I use mine all the time for things like cleaning up handle slots on cutting boards after routing them out with a bowl bit. Works great.

I have had mine for about 10yrs, and an in late November last year it quit. I took it apart and cleaned it (it was filthy)and found a loose connection. Tightened the connection and it runs perfectly. It was easy to take apart, and I was amazed at the amount of junk, that had accumulated inside.

IMO, the best “maintenance” for it would be to use it every so often, to keep the grease from coagulating and hardening in one spot. That seems to be what happens first. Grease dries out in one section and stops lubricating the bearings and other friction areas.

Have your say...
