    thanks. I did have the blade correctly installed. I am doing very light work so I don't think that I'm overworking the tool.

    Same problem on a Ryobi TS1552LA, next time I use it I'll carefully disassemble the blade and check to see if the washers are all correct, otherwise Locktite may be the solution

    Same problem on Ryobi TS1552LA, will check in a few days to ensure all washers are in place, otherwise, Locktite...

I completely removed the blade and put it back on, tightening the locknut, and now it works perfectly. The blade has not come loose and have used the machine for the last 3 months. The only thing I can think of is that somehow I didn't have the blade correctly installed in the first place, although it didn't wobble or anything.

    Well, the blade came loose again, I think it is because the brake slows down the blade so fast that it eventually loosens the locking bolt. I have now locktite'd the bolt and this seems to be working. Will post again if this fix fails, but have been doing a lot of work with it for the last month and this fix seems to be holding...

    It is now April 2010 and have just finished a large renovation, am happy to report that the locktite solution worked perfectly, the blade has not loosened up even with tons and tons of use!

  • enb54 Apr 19, 2010

    April 18 2010, and I have admitted defeat. The Ryobi has yet again come undone and now I have glued a zillion tons of Locktite to the retainer bolt, hopefully it will hold, will let you all know... I think this is really a braking speed problem, no one I know with any other brand has ever had this problem... Oh well, we`ll all find out again...

First of all unplug the miter saw and then remove the blade. Now examine the saw to check the direction of rotation. Be sure you are putting the blade on so that the rotation arrow on the blade is pointing in the same direction as the rotation of the tool. Now reassemble. Be sure to use some muscle to put the blade on fairly tight. Now when you use the miter saw let the blade do the cutting, do not overwork the tool by trying to cut too fast. good luck.

How do I fix the spring on the switch for a 10 inch ryobi miter saw? I can hear it rattling around and the switch won't work. Also plastic screws holding handle together are broken.

Hello Anonymous,
First locate the model number of your Ryobi Miter saw... then search Google for Ryobi Miter saw replacement parts... one result I got is below:
Try that link, select your Ryobi saw model and zoom into the provided drawings so you can locate the switch, screws, and spring (if needed). The part numbers are supplied and you can order them online easily on that same link... Then just repair your saw with the new parts. As you already noticed, the saw is easy to disassemble and get access to the parts for repair. Have fun and good luck...

Ryobi miter saw laser is way off. I can get it parallel, but it's about 1 inch away from the actual cut line. How can I fix the laser side-to-side?

Forget it. The lazer site gets obscured and useless after 5 minutes of cutting. It is the most useless improvement I've seen on a power tool in 40 years.

Ryobi mitre saw jamming when cutting

There's a normal adjustment process of squaring the blade to the table, page 19 of your manual. If the blade is not square to the table then it will bind. Here's the link for the manual, see page 19.

I bought the 10" compound

I have been in the same situation in the past, with a mastercraft miter saw to a point of using playing cards to get that nice tight miter joint. placing the cards between the fence and the piece i was trying to miter.Rioby makes mastercraft all thought they are a good saw they have their limits to the precisions of their cuts. good for fences,decks, stuctural framing ect, were a degree two is not a big thing,but when making furniture or interior trim work or picture frames or hobby craft you need to buy a good pro saw like a dewalt or bosh sliding compoud miter saw they may cost more **** their worth the money they are very precise and will last a life time if taken care of .It will be worth the money when you get that perfect cut every time you use it,it will put the JOY and fun back in your projects and not to mention qualaty in your master pieces.

you may have not gotten the blade on the arbor correctly, it sound like it is crooked, but if you look at the blade while it is spinning, you should see that. it is most likely the blade being crooked in the arbor, take the blade off and reinstall it.

How do I put water in the tile saw. Does it hook up to a hose?? I have a Ryobi WS720

Hello. I have the 730, and think they're basically the same saw. There is no hose hookup, rather you fill the reservoir manually and the pump will continue to feed it to the wheel. (Your's does have a pump?)

If with pump (like mine) - fill the resevoir to about 3/4 full and let the saw do the rest.

If no pump - make sure the waterlevel does''nt get below the cut line of the blade. It looks "shinier" then the centre of the blade. This is so the grit will not collect at the slot on the table or in the housing. That will prevent binding.

Here's Ryobi's cust. support # just in case: 1(800) 525-2579

Hope the info helps. Don't for get to rate this if you're happy.

thank you.

How do I replace my mitre saw blade?

It should still easily fit a 5/8" blade. The arbor shape shouldnt have any effect on the type of arbor hole needed on the saw blade (only round arbor holes are made on saw blades. You will probably find the arbor securing nut has a shape that fits into the flat gaps between the saw blade and the arbor when fixed. So grab a 5/8" round arbor saw blade and give it a go. It should work fine.
It is the arbor nut that secures the blade onto the arbor via friction which holds it on.
