There are tabs on the glide rings and yes there are only 3, you should find indentations in the base for the rings, I would clean them off thoroughly and use a lithium grease on them (film coat) check the table for signs that the rings have dug into it and if so smooth out before reassembling. If tabs are broke off the glide rings you would need to replace them. Let me know if you need more help

Bosch Glide Miter Saw get stuck at 45 degree bevel to the left


Adjusting the miter angle involves two cast surfaces sliding against each other. If those surfaces have some irregularities, high spots on the two surfaces will bind against each other. You may have to disassemble the rotating table from the base and do some filing or grinding.

Can't rotate Blade Angle for Craftsman Radial Arm Saw 113.23100.


The manual writer may have confused knobs or may have used different terminology to identify the same part. A call to Sears might clarify this issue, but then again maybe not. Check operation of all apparent knobs and you may locate the correct ones.

What is a compound miter saw?


A compound miter saw has a rotating vertical pivot allowing the cutter head & blade to be tilted (or beveled) sideways in addition to the horizontally rotating table. This allows vertical & horizontal angled cuts as well as cuts angled in both planes.

Craftsman radial arm saw will not cut straight. Even when I line up the blade with a square and try to cut a piece of wood with a straight line it cuts at an angle or a bevel instead of straight. Any...


All of the adjustment locks should be tight. Check the arm and saw motor cradle for looseness by trying to push/pull the blade, cradle, and arm in various directions. A bevel cut indicates that the motor/cradle is tilting. An angle cut is controlled by the rotation of the arm. Check for looseness of the cradle bearings that allow the cradle/motor to roll along the arm. If you don't have the owner's manual for this saw, go to: www.searspartsdirect.com and enter the complete model number minus the decimal point--this will take you to a series of drawings that detail every replaceable component of the saw. The owners manual should be available there. There is a rather involved series of adjustments involved to make this saw work correctly. Hope this helps!

The blade is turning backwards


That is physically not possible!

1. immediatelly switch off saw
2. remove cord from the plug
3. remove blade from machine
4. reverse blade 180degree and install it in direction of the rotation! if you look at saw from the blade side, rotation is clockwise!!! and cutting edge of teh teeth should point clockwise!
5. install and tighten the blade
6. plug in and switch in short burst only, check if it is rotating in proper direction and blade have teeth in proper direction
7. make test cut

Do not forget that this is not a toy, blade on circular saw cut through wood, metal and your fingers... always wear googles or eye/face protection shield, you have only two eyes and no spares...

Enjoy your woodworking experience! Always observe safety and machine rules.

Hope this allow you to fix the problem. Please leave note how did you go.

My craftsman 10-inch radial saw (model#113.199200) just stopped working. I had it in the driveway cutting some wood without any problems. It sat for a half hour and I went to use it again and it was running half speed then before I could even turn it off it just died. There was no popping sound or smoke, nothing! It will not start. Need help, please?

Looking for help scouts have a carpentry merit badge from the 50s they talk about using a BEVEl and a Miter tools can you help


The bevel is an angle fiding tool. it consists of a wooden section about 4" long with a swivel bolt at one end connected to a slotted metal blade (similar to a 1 foot steel ruler). The bolt has a wing nut and bolt to allow loosenig to allow the blade to rotate and slide to the required angle where it is locked into position using the wing nut.
The mitre is a wooden block with slots cut into it at pre determined angles. ie 45 degrees. When cutting a mitre joint the wood is placed against the block and the saw follows the line of the slot cutting the 45 degree angle.
Hope this makes sense and good luck

The fence may be getting in the way of the arm when you adjust the trunion assembly fully to one side or the other for bevel cutting. Adjusting the fence all the way out away from the trunion assy. should allow full 45deg adjustment. If this is not the case, it could be--even though its only slightly used--that there is sawdust built up enough in the housing to keep the arm from fully adjusting.

While the latch COULD indeed be faulty, it generally should always be tightened/locked so that the trunion assy. is fimly "locked" before cutting as this is designed to keep the saw from shifting mid cut, causing binding, uneven cuts, broken blades, seized bearings, etc.

Cannot rotate the Dewalt 708 mod 3 saw horizontally


If you have loosened the handle a little and pulling the adjustment trigger didn't allow for movement,you may need to remove and clean the turn table.(don't forget,the handle must be loosened for the turn table to rotate)
