The most common reason your circular saw blade stops spinning is because your workpiece is pinching the blade. This can also cause the blade to kickback. To prevent this from happening you need to support your workpiece properly to allow it to set securely through the entire cut.
The most common reason your circular saw blade stops spinning is because your workpiece is pinching the blade. A common issue for your Ryobi circular saw to keep stopping is it’s limited power capacity. The best way to keep your circular saw from binding is to properly set up your cut piece so that it doesn’t pinch the blade as you pass through your cut.
You also mentioned you tried tightening the blade so I must assume the blade is not freewheeling on the motor shaft after the motor and shaft comes to a stop. Depending on the type of motor and if it has any type of breaking, it could have a faulty motor or on/off switch. If I may be of further assistance as more details become available, please reply to this post along with the model number of the saw.
Most of the time, a circular saw keeps stopping because the blade gets stuck in the wood or material. If your circular saw can’t cut through the material, the most obvious solution is to buy a new circular saw that is more powerful. Circular saw blade problems are the most common reason for circular saw stopping during operation.
circular saw blade keeps spinning Related Question:
Why does my circular saw keep kicking back?
Overheating a saw blade can cause it to warp and result in a kickback. Buildup of sap on the blades, insufficient set, dullness and unguided cuts, can all cause an overheated blade and kickback. Never set a blade deeper than is required to cut the work piece 1/8 in. to 1/4 in.
Why does my circular saw motor turn but the blade does not?
A circular saw usually has a direct drive. I.e. the motor spindle is also the center shaft for the blade. So if your motor is spinning, but not the blade, it means the blade has lost contact to the shaft. Check if the blade is properly centered and aligned with all locating pins (if your saw has some).
How do you keep a circular saw blade from slipping?
Make a shim out of thin cardboard and place it between the inner blade washer and the blade. The blades they’re making these days are thinner than the older blades and some of the older saws have to be shimmed in order to prevent blade slippage.
What causes a circular saw to bind?
A circular saw binds because of failure to ensure proper blade depth; setting the blade too deep presents a danger because more blade surface is exposed while cutting than a properly set blade. When the saw is too deep, kickback and binding will be inevitable.
How do I stop my circular saw from binding?
Avoid circular saw blade binding But cutting a long board in half is different. You can hold one end, but the other must be free to drop or the blade will bind. The trick is to allow the cutoff end to drop slightly, but not so much that it completely snaps off before the cut is complete.
How tight should a circular saw blade be?
In general, the blades on right-handed circular saws turn counterclockwise, so you’d tighten the bolt clockwise; the blades on left-handed circular saws turn clockwise, so you’d tighten the bolt counterclockwise.
Where is the arbor lock on a circular saw?
Place the saw on a wooden surface and pull back the blade guard. If the saw has an arbor lock button on the top of the housing, press it in. The arbor is the shaft the blade installs on. If there’s no lock button, press the blade into the wooden surface.
Which way should diamond blade spin?
This indicated the direction – the tail should be behind the comet. If you put a blade on in the direction opposite to the directional arrow you may experience a little slower cutting or a little vibration at first until the diamond is exposed on the opposite side.
Why is my circular saw struggling?
Most of the time, a circular saw keeps stopping because the blade gets stuck in the wood or material. This is due to the blade not being powerful enough to get through the material. It could also be because the blade is damaged or the motor is malfunctioning.
Can a circular saw overheat?
Overheated Circular Saw Overheating of saw blades also cause them to stop. Fiercely using unsharpened blades for cutting require more pressure which cause more friction effects. These effects results in overheating of blades. Due to overheating the thermal switch stops the blade as a safety operation.
How do you lubricate a miter saw blade?
Apply a small amount of spray lubricant onto the blade of the saw and spread it out over the blade by hand. Let it soak in and wipe off any excess with a clean rag. Drop the blade guard back over the blade.
How do you tighten a Dewalt circular saw blade?
Press the blade lock then use the blade wrench to turn the blade until the lock engages and the blade stops turning. Continue to press the blade lock and turn the wrench counterclockwise to tighten the screw. NOTE: This is a left-hand thread bolt which means it must be turned to the left in order to tighten it.
Why does my saw get stuck?
The wood you are sawing is closing the kerf and pinching the blade, Your cut isn’t straight, The set of the saw teeth is not large enough, so the kerf created by the blade isn’t wide enough to allow the saw room to pass without undue friction, or. Your saw teeth are too fine for the wood you’re sawing.
What is the closest you should put your fingers to the blade while it is running?
Do not put your fingers closer than two inches from the blade. 3. Do not place your hands directly in line with the blade while cutting stock. 4.
Should a circular saw blade wobble?
The most common cause of wobble like this is that the bearings or bushings are worn out. These are the things that hold the main shaft in place. They should be a close fit to the shaft, and the shaft rotates within them. When they are worn out, there is too much room and the shaft flops around or wobbles.
