Problems with miter saw cutting at an angle.

I just went to the Firestorm website. They have manuals for download in the customer service area. I am not familiar with your saw. I just use a small square and make sure my blade is square to the table and the fence.

From your picture, it looks as though the vertical position is off a little.

As “Steelmum” said, use a small square to check to see if the the blade is perpendicular to the table. also use a framing square to check if the blade travels perpendicular to the back fence.

looks like the fence is not square with the base. it may also be blade deflection. check for runout and exesive bearing play. also be sure the blade is sharp. if you are using the blade that came with the saw that may be the problem. most tools I have purchased came with realy crappy blades. I have 2 hitachi 15” miter saws that cut as true as can be but the original equipment blade got pitched on day one because they were junk. there may be ajustments for out of square or you may have to shim the fence.

One tool that I have found helpful with setting my miter saw is the Wixey digital angle gauge.

Tony has posted a review of it here.

This tool is well worth the money.

Thanks everyone, appreciate the info – it’s a big help.

is the saw a compound angle saw? if it is the 10” 15-Amp Miter Saw with Laser (FS100L) then there is an adjustment knob in the back of the saw that allows for the head to be moved to an angle. This is probably out of kilter loosen the knob and make the adjust ment necessary with a square and probably a wrench. The saw will sometimes move out of adjustment just by picking it up by the handel. It is always a good practice to verify trueness in new tools befor you do anything else with them. This will often times enlighten you to things the tool is capable of when you had no idea

I had something similar to this happen to me on my DeWalt. It cut great for a long time, then I switched blades (went to a cheaper one), and it cut terribly. The blade would actually cut crooked and at an angle thru the wood when the squares said everything was good and straight. I junked the blade, and bought a really nice one. Now, it cuts like a dream.

You might check for excessive bearing play, and almost all of these have adjustments that you can make to the “0” mark for square. Go to the manufacturers website and you’ll probably find a manual.

Good luck,
