Blade running the wrong way

I'm not sure if you have a chop saw or circular saw. Either way, it sounds like the nut and washer are not tight enough to hold the blade. If you have a circular saw clockwise will tighten the nut and washer onto the blade and hold it in place. Most chop saws are a left hand thread and then you would turn the nut counter clockwise to hold the blade tighter. The blade wobbles because it is not tight.

On any saw blade, you will loosen the nut (or bolt) in the direction that the teeth of the blade are pointed. This is because any saw must be designed so that the force of the material being cut pushes against the blade in the direction that would tighten the blade. So, on a miter saw with the blade on the right, when viewing the blade from the right the teeth are pointing counter-clockwise (or left), so you loosen to the left. On the other hand, a radial arm saw or a circular saw where the blade turns clockwise, loosening will be to the right. Good luck.

Lock blade and undo the blade locking bolt in the direction of cut, normally anti clockwise if the blade is on the right. Lift guard and lift off blade. refit with new one insuring the bore size is correct. refit outer flange and bolt.

For any saw blade or grinding wheel, the rule is this. Pushing against the points of the teeth should be the direction that tightens the nut. So you must loosen it in the same direction that the blade spins. For example, if your saw blade is on the right side of your saw, then the blade spins counterclockwise, and the wood pushes against blade clockwise - so you turn it counterclockwise to loosen it (which is in the same direction that the blade spins.). If the blade is on the left side of the saw, you loosen it clockwise. Good luck, Al K

Hi, You need to turn the bolt anti-clockwise to undo and clockwise to tighten back up. Make sure you take out the battery and press in the spindle lock before you change the blade.

Push the yellow button on the right side of the blade gaurd there is a hex wrench under the grip handle that stores in the body with yellow butten depressed turn hex bolt clockwise ot lossen its a left handed thread so it dosen;t lossen during use remove bolt and washer raise blade gaurd remove blade when installing new blade note arrows printed on blade the saw rotates clockwise teeht face forward

You are correct it requires a 6 1/2" blade. You must use a 6 1/2" blade and cannot install a larger blade.

sounds like its striped. may be a clockwise thread or reverse thread. try to pry the bolt up while turning

Hello daobrien,
Not to worry, I think I can help you with your problem. You can try the WD-40, but first try the following. (Sounds like the repair shop wants you to come back.) First what I recommend is that you use your adjustable Vise Grip pliers and clamp it to the front of the blade. If there is a plastic shroud in the way, you may have to remove it temporarily. Doing this may give you enough leverage to loosen the nut. Apply the WD-40, then try to twist off the nut. The idea of using the pliers is allow you to not have hold the brake lock and give you the ability to apply enough torque to do the job. I have done this same thing when my framing saw nut was on to tight and it worked for me. Let me know if this is successful for you. If you would, please a positive feedback for me. I will very much appreciate it. Good luck! :o) Regards, NormanZ

Am I correct that this is a hand-held saw? Want to make sure of the terminology.

If so, the bolt holding the blade has right hand threads -- meaning it loosens by turning counter-clockwise.

Is there a blade lock? Are you using it?
