Replacing blade in circular saw

[Keitai]

Quick question, when I change the blade in my circular saw do I turn the alan key left or right to undo and then which way to tighten whilst pushing button (circled) ?

Turn it, the direction that loosens it, and then the opposite direction to tighten it

 

[Munroast]

It will loosen in the same direction as the blade spins, so on the one in the picture it will be clockwise to loosen.

That will be a left hand thread, so you turn it clockwise to undo.

To make sure blade is right way round, have arrow and teeth pointing some way I guess. Just finger tight when putting nut on

You're going ahead with it then?

If you are not sure which way the blade is going to spin, then don't use the machine.

and it needs to be more than finger tight (esp with that allan head) be careful not to over tighten, but you need to nip it up with the key, and then check the blade is tight and straight.

He's asking the building surveyor first but I suggested not the 1st floor window just bottom one because of that flashing stuck around under sill.

He'll get back to me.

Thxs BTW

I meant finger tight or finger tightened with Allan head in it not finger tight with just my fingers. Is that what u mean?

By asking this question shows that you shouldn't be using it!

OP, The answer to the original question is: You tighten the blade by nipping up counter clockwise with the allan key.

Post #4: you obviously dont know the answer to the original question - so dont say anything where saw safety is involved.
Attempting to give a slick answer is dangerous & foolish.
Just a little too much pressure in the wrong direction can cause some blade bolts to snap off.

If you are so observant you will have noticed that he has already changed the blade and then asked how do you remove it.

Post #15, what is your point? Please explain?
The OP asked a question - I answered his question.

Have you really had that happen on a trade tool? (BTW the OP has a deWalt cordless saw) A couple of times I've rounded the cheap and nasty hex keys that some manufacturers supply and I've similarly rounded out the hex socket in the blade bolt, so common on saws nowadays, a couple of times (the last one I fubarred was several years ago and was actually a Hilti saw) but other than smacking the key or spanner with a hammer, surely a blade bolt isn't going to snap very often? Maybe this is the reason why many saws these days use a hex (Allen) key/hex socket bolt arrangement - to negate the potential effects of heavy handed abuse?

Fair enough - I've never experienced it but I've read reports of it happening.
The reports were in a professional trade journal.

I also agree that the Comes With the tool keys & spanners were/are mostly a waste of time.
