How to fix KS12-1 circular saw?

[gencomm]

My KS12-1 circular saw blade slips on the spindle. how can I fix this?

Welcome to the Bunnings Workshop community @gencomm. It's brilliant to have you join us, and many thanks for your question about circular saws.

With the flange installed correctly, the nut tightened sufficiently and using a circular saw blade with a bore size of 20mm, your blade should not slip. If this is the blade included with the saw, I'd recommend you double-check that the nut flag is installed correctly; it might be flipped the wrong way around. If it is installed correctly, I suggest returning the saw for assessment from our team in-store.

Please let me know if you have any questions.

Thanks for the reply Mitchell,

can you send me a picture of exactly How the blade is installed on the saw?

Hello @gencomm 

Below is the brochure for the AEG KS12-1. There is an illustration on the start of page three how the bolt and washers are arranged for installation.

Here is the link for the brochure: AEG Instructions 

If you need further assistance, please let us know.

Hello Eric thanks for the instruction drawings.

I am happy that every thing is done correctly.

The blade has been allowed to slip. now it will not tighten. all the spacers are in place. is this a problem experienced by others?

I think there is enough of a recess to the flange collar (for want of a better term), unless there is end float in the spindle shaft.

The threaded socket for the retaining screw is "blind". I fitted the extra spacing washers to make sure the screw wasn't bottoming out.

I just had a thought though, maybe the spring washer thingy got too hot and lost its spring/grip?

what do you think? It is still possible to turn the blade by hand with the spindle locked!

Hello @gencomm 

I'm going to ask you to stop right there and make no further adjustments. Please do not operate the saw under any circumstances. I suggest bringing your tool to the store and speaking to the senior tool specialist in the tool department. I recommend showing them your circular saw and letting them see what's been happening in regards to blade installation. I propose asking them to show you the display of the AEG KS12-1 and looking at the blade installation sequence. If anything is amiss you should be able to see it with the display set at the store.

If you need further assistance, please let us know.

I have already done that. the tool specialist was polite but unenthusiastic. there was nothing to show me anyway. as packets were sealed and the appliances mounted and locked to displays. there were no spares to buy

I was not powering the machine up, but looking at the tolerances.

these seem to me to be ok....Except, as I said, the spring washer my have been overheated.

Are you able to provide me with a part number and were I can purchase one from?

Hi @gencomm,

In the blade installation section, I note that the flange washer is shown with the tapered edges facing outward and the flat portion against the blade. In your images above, it appears that the tapered edges are towards the blade, with the flat surface facing out. If this is the case, please remove it and attach it facing the other direction.

Please let me know if you have any questions.

Hi @MitchellMc 

When you look at the magnified image on Bunnings - the outer flange doesn't appear to be beveled/tapered?

I'm wondering if the end thread of the locking bolt has been stripped?

Any likelihood of this @gencomm ?

Cheers.
