Question about Saws

Open Question

Model 6955-20. Brand new. RPM flutter at full speed. Sounds like loose blade but it's tight on the arbor so maybe it's normal for a 12 to sound like it's fluttering at high rpm.

No load, gentle cut, hard cut. Saw blade seems to make uneven sound. Not bogging down but doesn't seem to have steady rpm.

    was just wondering if other members/contributors own that saw and or if there's experience with a motor that would fluctuate in sound indicating to me there is a bearing problem

The bearings in your saw need to be replaced. I would contact a DeWalt store to obtain the parts or have them do the repair. You have an excellent saw there, well worth repairing. good luck.

SOURCE: blade acts unusual

Hi, Blade wobble at high speed can be very dangerous! The saw at the right ( wrong) wobble can destroy itself.There are a few things that can cause it, And you have to check them as best you can before you power it back up. Check the blade, you can lay two blades together and check for gaps anywhere. Check that the hub and spindle are flat where the blade goes. (No lock washers) Also check the spindle for side to side movement, there shouldn't be any. Turn the spindle by hand and see if you feel any grit or sandy type feeling, you shouldn't. Lastly, if you don't find anything, try a new blade of a different type, and if it wobbles again, check and see if you have any warranty left and even if you don't you should contact Makita about it.
About the best I can do from long distance. Let me know what you find, Please.

SOURCE: loose replacement blade

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.

New to table saw use, have my husbands old 10 craftsman, was learning to rip with it doing fine, then it started to bog down during cut until the blades stops, moving. put on a new blade and noticed...


If I understood correctly, you started using your husband's table saw and while ripping boards, you managed to stall out the blade AND motor?! If that's the case, you probably have a very dull blade and are binding your board on the blade. Neither is safe and it sounds like trouble is brewing.

First and foremost, get someone to show you how to safely and properly use and adjust the saw if you are new to wood working and power tools. That saw is capable of turning your lumber into a high speed missal if you do things improperly.

It also sounds like you tried installing a new 10" saw blade. Changing the blade requires 2 wrenches. One to hold the arbor and one to tighten the nut. The blade itself should rest on the arbor between two large washers. Also make sure you install the blade so the front face of the cutter teeth face you and rotate toward you. Make sure the saw is unplugged when changing the blade and never turn on your saw with a loose blade.

Kawasaki fb460v overcharging battery???


It sounds like the voltage regulator is bad. It may be located on the blower housing which covers the flywheel. Should have a large plastic plug connecting to it. If you don't see anything like this then give me the engine spec number so I can look it up. It would be something like "AS09" and should be located where the engine model and serial numbers are.

I have a DW402 4.5'' angle grinder and do not know how to remove the blade to install a new one. Could someone help please?


On top of the head there is a button to press to lock the blade arbor. Press it down and turn the blade by hand until it locks in place. Then you need either a spanner wrench or nut wrench depending on which arbor nut you have. Grinders usually come with whichever wrench they need. Most grinders have an arbor nut with two or four holes and require a spanner wrench with two studs that fit into two of the holes to remove the arbor nut. Some have an arbor nut with a hex fitting, like a regular nut & bot setup, that the arbor wrench fits on. If you don't have the proper wrench sometimes you can get the arbor nut off with a pair of vice grips or pliers. You will want to turn the nut in the same direction as the blade spins when the grinder is on to remove it. When you put the new blade on, get the arbor nut hand tight, it is self tightening and will get tighter as you use the grinder.

Why is my tile saw making different noises?


Sounds like you have bearings going/gone bad. If it's a direct drive model, check the bearings in the motor and on the arbor. If it's a belt driven model check the bearings on either end of the arbor shaft. As bearings go bad, someone using the saw regularly will notice a different tone in the tool. If you are getting vibrations that bad, the bearings are already loosing balls or the race is tore up and all the balls are on one side and can't doing their job correctly.

Blade shaft slipping


It could be a number of issues. These saws have a built in vari-torque clutch used to prevent kickbacks. Basically, when the blade binds while cutting, the arbor spins but the blade won't (prevents kick-back). It works by not over tightening the blade washer (this is the slip clutch), if you over tighten, the blade washer can't prevent kick-backs because it has no room to slip, if you under tighten, the arbor spins, but the blade won't. I'd try to tighten the blade washer 1/8 turn and see what that does. If your actual arbor shaft is not spinning, you could have a gear issue. If you hear the motor running and the arbor slips (not the slip clutch) sounds like there might be a gear issue,If the rotor is spinning (the part inside the stator-i.e. the electric motor section) but it is not transfering that movement to the arbor, it has to be a gear issue.

This is common IF the blade clamping nut becomes loose... the blade will free wheel on the arbor after the motor stops. It can tear up the arbor so investigate this possibility immediately.

PTO Issue


It sounds like you got the cable to tight. The brake cable applys the brake to the pulley to help stop the blades when PTO is disengaged. With it being tight it might be applying the brake and that is the reason your blades are not running at full speed. If you keep using it that way it will wear out your brake and possibly damage a pulley. I suggest you loosen the brake cable or replace it with a new one.
