Question about Fein FMM250 Start Multimaster Oscillating Tool Kit

1 Answer

Information on usage of oscillating saws

When Fein's patent on oscillating saws expired, several other manufacturers started making similar products. As it happened, I happened to have job for which I thought this type of saw would be perfect, but I was not familiar with the tool, so I asked Fein about it through their website, and I called Rockwell several times over several days. Fein never answered my message and Rockwell never called me back as they kept promising to do. Finally, giving up on them, I purchased the same kind of tool from Chicago Tool, because I was at least able to get some useful information from the man I talked to there.
I still don't know as much as I would like about this tool, so I am wondering if there is any book or manual that would help me in their use. The tool hasn't yet arrived, but I would like to prepare myself before it comes.

    I wish that you had posted my initial inquiry when you asked if I had found a solution. I had forgotten that I had asked about a book or manual for oscillating tools, so my last posting wasn't entirely appropriate. I still need such a manual. Thanks.

My "solution" was that I finally realized that Fein and Rockwell do not believe in providing service, so I had to look elsewhere. I called Harbor Freight, was able to get the advice and information I needed, and purchased a oscillating saw made by Chicago Tool. I would have preferred a Rockwell Sonicrafter, but after experiencing Rockwell's attitude towards potential customers, I realized that I would not be able to get the help I needed now, nor in the future should I have bought their product.

One good thing came of this experience: I learned of your servixe, and I am bookmarking your site.I'm sure that I will be making use of it some time in the future.

Fein multi tool won't release sanding attachment

A waste of time to spend with this budget machine, unfortunately, be replaced is usually not make sense relative to the new value of the whole and in rapid succession, the following defects no spare parts to get for only a complete new head . thats fast about 50 % of the new price , NOT REPAIR is a good no the best advise in that case. if its not a FEIN supercut its not worth it to even do something to in that case it has only the name FEIN but its having very soft metals.

Fein multimaster repair shops/centers????

Wow, I don't have a multimaster but I want one. I know they make two kinds. One that's 700.00 dollars and one that you can get at the hardware store. I'm beginning to think there might be a problem with the switches in this thing. Go to and view the schematics to order a new switch.

Pretty sure things like that are considered expendable. Pat yourself on the back for getting so much sanding done and buy a new one.
