Makita LS1016L Blade Wobble After 8 Months


I've bought this miter saw brand new from HD this past March. I've used it off and on since then as required by the job (not used every day). I jump back and forth from framing to finish carpentry, and stuff in between.

Anyhow, I'm doing a cabinet & trim installation job these last few weeks and decided to clean the blade (bunch of pitch built up from a hardwood floor job). I normally use this CMT 80T blade for finish work. I took blade off and used CMT blade cleaner, got all the pitch off, put the blade back on the saw. I immediately noticed wobble. First, it was non-normal vibration that was never there while blade is spinning freely. Second, I can see the obvious wobble as the blade comes to a stop as I sight straight down through the blade guard. I took the blade off once more and reinstalled it just to make sure I didn't under or over crank the arbor with just enough pressure to keep tight. Same issue. I'm kinda peeved because I had some tear out on pre-finished custom built-in pieces I was installing yesterday and now have to do touch-ups (boo).

So fellow Makita users....before I go contacting Makita service, what should I check for (obvious stuff). I read on line something about arbor run-out? Not sure how to check for this. I know some people have had wobble issue with this saw. I'm surprised that it's cropped up now after 8 months of trouble free use. First thing Monday, I'm going to put the Makita factory blade back on and see what happens.

Oh and as a side note, both sets of rails have started to show rust at the very ends that are exposed when in the closed position. I'm working a job right now that right in front of the ocean so it comes with the territory but nevertheless, it's not "new" anymore.

Get a new blade and see if it still does it.

May have just warped the blade. If it gets a lot of pitch buildup, it will also heat up the blade more when cutting.

Heat destroys metal. Warped, really.

Re: Makita LS1016L Blade Wobble After 8 Months


it can very easily be a warped blade.. if it still happens with a new blade could be the bearings.. dewalts are notorious for this issue

Thx for the spell check. I'll order the exact same blade and see what happens. In the mean time I'll see if the Makita factory blade behaves any different.

Had the same symptoms with my dewalt. Didn't know about ereplacementparts.com and also time sensitive so I had it fixed by dewalt. Expensive and disappointing.

Warped blade is a very good possibility. It does not take much to warp them no matter how thick.

Also check between the blade & arbor plate to be certain there isn't a piece of crud in there.

Is that the CMT ITK Plus blade from Lowes? I have used them and they are good blades, but it doesn't mean your hasn't gotten warped. Most of the time it happens from the saw getting bound up.

No I bought this one from Amazon. The only local place that carries them around me is Cabinetware about $20 more retail. I was in Lowes today and it seems that they've cleared out their CMT stock.

Re: Makita LS1016L Blade Wobble After 8 Months


You get 8 months out of a blade? Holy ****!

Anything can happen to warp the blade. A kickback can do that.

I used to get Amana blades. There were two different models of the same size, almost exactly the same blade, but one is total junk on a SCMS and the other is top notch. Can't explain how that is.

I am now completely Forrest sawblades for the SCMS.

Re: Makita LS1016L Blade Wobble After 8 Months


Yes, I have 8 months on this blade. It's still sharp enough to scratch my fingernail. I don't use my miter saw on a daily basis for the 8 months. I had demo, flooring, and framing jobs in between the trim / cabinet installs. I do clean the blade often when I do use the saw, that might make a difference. And I don't cut any rough wood like studs, PT, or plywood other than cabinet plywood.

Update: all is well in Makita 1016 land. I pulled the blade off this morning and behind the last arbor plate was a bit of pitch buildup. Not sure how it got there because the arbor plates get cranked down hard. I wiped it off and made sure to blow the area out with an air chuck. Blade no longer wobbles crazily and cuts true and straight. There is still a tiny bit of vibration at full throttle but it feels the same as when I first got the saw so I think it's normal. The cuts are straight when I flip a test piece over. Thanks for the tips gentlemen.

Haven't needed to yet, seriously. I've got a bunch of 12" blades from my old Dewalt saw all freshly sharpened with that waxing around the teeth. I use National Saw Company out of Lakeland FL. Their sales rep, John Huggins, picks up blades from whatever job site you're on. Excellent service.

Re: Makita LS1016L Blade Wobble After 8 Months


Another issue has popped up with my Makita. The miter table detents are "loose". As I swing the table, it'll slide into "0" (or any of the other detents 22.5, 31.6, 45) and the thumb lever pops up. But I have play left and right on each detent...about 1/4 degree left to right. Might not seem like much but it's a big deal for me. I've messed up a few cuts until I realized the problem after first squaring the fence thinking that was the problem. I'm having to lock down the table at each detent now. Any ideas?

I looked underneath the table and basically there's a pin (233 in the diagram) that springs forward into a cut out in the base, maybe that pin is worn out and needs replacement? Anyone else have this happening with their LS1016L?

Re: Makita LS1016L Blade Wobble After 8 Months


No I have not had that problem with the detents. Sounds like something is loose or worn.

If your interested in good blades buy a Forrest Chopmaster or a Tenyru miterpro.
