Nut problem Hi - My fan stopped running smoothly the other night and the problem seems to be with the fan blade nut. The blades are not tightly affixed to the motor because the fan blade nut will not fully tighten/fasten. I've been trying to get the nut off to re-do it, but it won't come off. Any suggestions? Thanks!

you should have an open ended wrench that came with the unit. the arbor is flat on two sides, use the wrench and let it rest aginst the side of the saw, then turn the nut

It's out of balance. Causes:

#1 Fan blades are dirty, remove guard and clean.
#2 While guard is off check to see if blade retaining nut is loose. Tight is counterclockwise
#3 If loose make sure blades are in the notches on the back at the shaft. Align and tighten.

If none of this works get a new fan.

Hope rhis helps Mike

I'm not sure if you have a chop saw or circular saw. Either way, it sounds like the nut and washer are not tight enough to hold the blade. If you have a circular saw clockwise will tighten the nut and washer onto the blade and hold it in place. Most chop saws are a left hand thread and then you would turn the nut counter clockwise to hold the blade tighter. The blade wobbles because it is not tight.

Assuming the obvious that the motor is turning, the only thing that would keep it from cutting is that the nut holding the blade is not tight enough or the sping washer between the nut and the blade is missing or on backwards. The correct orientation of the spring washer is so the inside surface around the hole contacts the nut, and the outside circumfrance of the washer contacts the blade. P.S. the nut is tightened very tight.

-Remove the blade cover.
-Loose the nut that hold the blade. Loose the blade tension.
-Remove the old chain then put new one in. Tight the tension to
to good or until the chain still turn smooth. (Not over tight)
Tight the locking nut.
-Put the cover back.
You're done

Good luck end enjoy

Hello,
The model no. does not seem correct.but it seems as if the hole in the fan blade which is normally D shaped has worn round.The thread on the shaft is Left handed and you will need to undo by turning clockwise. If you can get a vice grips at the back of the blade to hold the shaft then try again,or you will need to get into the back casing and try jamming the shaft at the motor housing you may need some help.Then if that works you will need to undo the 3 bolts holding the Motor body to the rear casing.The new fan would normally come with new bolts,blade and nut.To tighten fan blade nut use a 10mm socket hold the fan blade and tighten anticlockwise.Hope this is helpful.

Good luck.

grab it real tight. wiggle and voila...it pops out.


remove fan blade nut. left handed 22mm nut also 1.25 open end american will get it.

must remove fan shroud with blade.

upper and lower hoses, airbox and sensor wires, coolant expansion tank, and anything else you can see in the way. must use a grabber tool when removing fan blade nut.

Hi these are usually the opposite way to which the blade turns but you may have to use a rattle gun to remove this. If you have a look at the thread you should be able to determine which way it comes off. Just remember to fix the blade so it wont turn and take your fingers off.

Take a pair of vise grips and clamp the blade to a 2X4 for more leverage. Some old edgers had a left hand thread.

Most fan blades are held on by a single nut, which is usualy a left hand thread, so to unscrew it you turn it clockwise as though you are tightening it up.and to tighten it,anticlockwise..
If the spindle turns, then you will have to hold it with a pair of grips or similar.
Plz rate my solution.
