How many bumper strips on your MS311 or MS391?

[Gomofast]

Working on an MS 311 and noticed that there are only 3 bumper strips when there are clearly spots for 4 of them. I assumed one had just fallen off, so I went to an IPL to find the part numbers. Interestingly, the IPL only shows 3. Two on the cover side and one by the clutch (I've circled these in green below). But you can clearly see that there's a spot for the 4th (circled in red). So I'm curious if the IPL is just lacking the 4th or if they were actually only given 3 from the factory for some reason...



Let me know how mahy you have on yours. Thanks!

The saw uses two pieces of part 18 and part 20. But part 18 and 20 are the same part. So you have 4x bumber strip 1121 648 6610.

That's what I assumed as well. I wonder why the IPL only shows one #18 - perhaps just an oversight.
