Question about Ryobi Saws
Unplug the saw. If the blade is moving, wait for it to stop. If the blade arm is locked into its down position, push down slightly on the blade arm to release the tension on the blade arm lock pin. Pull out the lock pin to release the blade arm and allow it to move upward.
2 Rotate the lower blade guard upward and expose the Phillips-head screw that holds the blade bolt cover in place. Loosen the screw and rotate the blade bolt cover up and out of the way to expose the hex-head blade bolt.
3 Push the spindle lock button in and rotate the blade bolt until the spindle lock engages fully, stopping the ability of the blade bolt to rotate.
4 Loosen the blade bolt using a 10-millimeter/12-millimeter combination wrench. The blade bolt is lefthand threaded, which is the reverse of conventional threading. Turn the bolt clockwise to loosen and remove it. Note the placement of the outer washer and remove it as well.
5 Place a drop of machine oil on the inner blade bolt washer. Do not remove the inner washer. If it is missing, replace it before replacing the blade.
6 Slide the replacement saw blade up past the lower blade guard and onto the blade spindle. The blade teeth should point downward at the front of the saw. Saw blades often have rotation arrows that can help you double-check that the saw is installed to rotate the correct direction.
7 Press the spindle lock button in to lock the spindle and reinstall the blade bolt. The blade bolt will tighten in a counterclockwise direction. Replace the blade bolt cover and install the blade bolt cover screw.
8 Position a combination square to check that the blade is square to the saw fence and saw table. If the blade is not square, refer to the procedures in the manual for squaring the blade to the fence and table.

There may be a push button type blade lock, and on many of these saws the retaining bolt for the blade is backwards threads, e.i., looking at the top of blade retaining bolt, turn it clockwise to loosen. This would normally tighten, but in the case of many of these saws, it loosens it.

The first picture is the only one I could find of your saw.
All saws are fitted with carbon bushes that contact the armature of the electric motor.
In time the carbon which conducts the electricity wears down, as they disintegrate there are particles of broken carbon connect with the armature giving an intermittent burst of power, eventually the bushes no longer contact the armature and the saw does not work at all.
The next photos show the approximate position of the cover to access the bushes, there is one one each side of the housing.
They usually unscrew and expose the spring plate the bush is mounted on, gently pull this out.
As you can see the bush is worn in a concave shape, and that the wide side is breaking up.
If this is your problem then take the bush and model number of your saw to a supplier or spare parts shop or the hitachi web site to get replacements.
Hope this helps.

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.

The manual is posted on line. Changing the blade does not require turning the saw over, blocks of wood or vice grips. The advice listed above is potentially damaging to your equipment.
