How do you change a blade on model 36-075


Lots of saws have left hand threads on the nut that holds the blade in place. It is designed so that if the saw starts up and the nut isn't snug, the nut and the blade slipping on the turning arbor would tend to tighten the nut as they slip against the force of the spinning arbor.
1. Unplug the saw.
2. Hold on to the blade tightly with one hand.
3. Put the wrench on the arbor nut and turn it in the direction you would turn it as if the wrench were turning the blade to cut wood.

If you've previously overtightened the blade, jamb a piece of wood against the teeth and the saw table top and then follow step 3.

If the motor is on the left side of the blade as you face the saw, then it's a standard right hand nut.
If the motor is on the right side of the blade as you face the saw, then its a left handed nut.

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.

Can't loosen arbor nut


Use a block of wood to hold the blade from turning and pull the wrench toward you. Most saws will have the nut on the right side of the blade and will use a right-hand thread. But if the nut is on the left side of the blade, it will be a left-handed thread. In either case, PULL. The crescent wrench should work fine if you place the block of wood in a position where the blade naturally jambs into it and cannot turn. If the washer is correctly placed you do not need to tighten the nut all that much. If it is really stubborn, use a little WD40. Clean it off thoroughly after you get it apart.

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.

Having problem get blade off table saw any hints


Unplug the saw, first and foremost.
Then see if your saw arbor has facets for a wrench behind the blade, and if so, try to find a slim wrench that fits there to hold the arbor while you attempt to loosen the arbor nut that holds the blad on. If that doesn't work, take a stick of wood, like a piece about 3/4" x 1 1/4" x 12-16" long, remove the throat plate from around the blade, wedge the stick between the blade teeth and the edge of the throat slot to hold the blade in place firmly, exerting levered force toward the center of the blade to hold it in place, and using the wrench, loosen the arbor nut. Make sure you are attempting to loosen in the correct direction. Depending which side of the blade the nut is on, some nuts are reverse threaded.
Good luck.

I have a Ryobi WS730 wet saw. I suppose the manual was discarded by my wife with the box. I need to change the blade and do not find a stopping mechanism to hold the blade while I use a wrench on the...


The saw should have come with a wheel wrench and a hex key. The hex key will act as your stopping mechanism if you hold it.

With the saw unplugged, loosen the wheel guard lock and rotate the wheel guard to expose the arbor nut. Put the wrench on the arbor nut and a hex key in the spindle. Keep the wheel from turning with the hex key and loosen the arbor nut with the wrench (turn counter-clockwise). Then remove the hex key, wheel wrench, arbor nut, and outer washer to access the blade. Remove the old blade then wipe a drop of oil on the inner washer. Place the new blade on the spindle. Replace the outer washer and then the arbor nut. Again use the wheel wrench and the hex key to tighten the arbor nut while keeping the wheel from turning. Then replace the wheel guard and tighten the wheel guard lock.

The manual is available from Ryobi: http://www.ryobitools.com/catalog/power_tools/tile_saws/WS730 . The direct link to the manual is http://www.ryobitools.com/product_manual/file_url/11/WS730_414_eng.pdf .

I hope this helps.

(If you can't find the hex key, get another that will just fit the opening in the spindle.)

My saw problem has to do with changeing the blade. I'm useing a thin kirf blade. When I change the blade I have to put a wrench on the arbor next to the pulley to keep the arbor shaft from turning when I...


The nut is binding on the arbor because the threads are buggered up or clogged with something. It could be the nut (which is probably brass and soft) or the arbor (which is steel). If it got a little cross threaded, the damage will be on the nut. It might be the arbor if the arbor took a whack. Once you have it apart you should be able to see it - although the damage might be pretty small. You aren't likely to have a tap and die to run through the threads, but you can probably fix it with a little rotary tool (like a dremel) using a small disc. If it is the arbor you can use a triangular file. Or you can buy a new nut. I hope this helps.

How do I lock the spindle in order to change the blade?


As long as the threads on the arbor and the nut are in good shape, you don't really have to hold the arbor from turning, just the blade. Use a block of wood in front of the blade with the blade raised all of the way. Put the wood down in recess in the table in front of the blade and just pry against the blade. This works almost as well on the back of the blade when you tighten the nut. When you are tightening, the teeth are not pointing to your advantage, but you don't need to tighten the snot out of it.

I can't get the blade tight enough


If you tightened it enough and it still slips than it may be missing a spacer Try adding a washer to the arbor of the same size on the nut side of the blade.

Many of the old saws don't have an arbor lock. If yours does, it would appear as a button or lever on the motor housing, sometimes underneath, sometimes between the blade and the motor/handle assembly. If you have such a lock, use it. It keeps the blade from spinning.
If not:
First off, unplug the saw.
Then look on the inboard side of the blade and see if the collet washer or arbor has facets for a wrench to grab it. Some older saws had these. If so, you can use one wrench to hold the arbor from turning and another to break the blade nut loose.
If not, lock the blade in the down position or hold it down against the base, and carefully jam a block of soft wood (like a hunk of 1 x 4 ) between the teeth of the blade and the table. You ought to be able to exert enough pressure to hold the blade from turning while you loosen the nut. (You''ll have to have the wood in the right position either fore/aft of the blade to keep it from turning). Once it's loose, you can hold it by hand and spin the nut off.
Reverse process to tighten.
