my sieg C2 300 lathe makes a whirring noise but does not turn the chuck
Hi. I have a new Sieg C2 300 mini lathe that I used for the first time a few days ago.
The manual said nothing about any particular method of using it for the first time, so I turned it on and gradually increased the speed to about halfway, then I noticed that the "fault" light had come on, so I used the emergency switch to turn the lathe off.
Later, however, I realised that I had not installed the chuck safety shield, which has an electrical connection, hence the light.
Worried, I tried the lathe again, having installed the shield and made sure it was down. this time the light did not come on , but the chuck turned very slowly and then stopped.
I could hear a whirring noise.
When I removed the headstock cover to expose the gear train, there was nothing untoward to be seen.
When I turned the lathe back on, the gears did not move and there was just the whirring sound.
I've been in touch with the suppliers but I really do not want to have to pack it up and send it off, given its weight and size.
Perhaps the motor was faulty from the start, or perhaps I damaged it.
Either way, I would be grateful for any advice.
i read in a mini lathe handbook, by the way, that a new lather should be run in. Cheers, Laurence

If you hear a whiring noise, i assume that is the motor turning? so that would imply a drive belt has come off?
Just a guess.

Above are my opinions Below is my signature.
Would you hit a nail with a shoe because you don't have a hammer? of course not, then why work on anything electrical without a means of testing Click Here to buy a "tester" just because it works, does NOT mean it is safe.
If gloom had a voice, it would be me.

Could be a belt off as said above. Not got a clue really, but looking at the manual online it looks as if there's a high / low lever on the back of the headstock.
Is it properly engaged in either high or low range?

There is a user guide pdf download for that model on the Axminster Tools Site. It looks like there is a lever to disengage the leadscrew from the gearbox maybe you have inadvertently shifted it.

Hi Dave 54. thanks for your reply. Yes, I tried it with the gears engaged and disengaged. Thanks again.

Hi someone-else. Thanks for your reply. Not sure whether to go ahead and expose the belt. Depends on how easy it would be to put everything back in place. On seconds thoughts I think I will.

The only other thing I can suggest is that you check all the couplings in the drive train, any grub screws on gears or pulleys etc. etc. for tightness.
Can't hurt to check the whole thing over for tightness really.
As already said, it sounds as if the motor's turning. Check it actually is.
Really though if it's not working, I'd contact Axminster.

Hi Firewatcher.Thanks for your reply. Yes, i tried it with the gears engaged and then disengaged. I'll have to find out whether it's true that I should have run the lathe in, which presumably would mean starting with low gear. But when I first used it, it was in high gear I'll just bite the bullet and take toe motor casing off to look at the drive belt. Thanks again.Firewatcher wrote: ↑Sun Aug 30, 2020 7:47 pm There is a user guide pdf download for that model on the Axminster Tools Site.

Hi Dave54. Thanks for your instant reply. The gears I checked did not have any pulleys, so the drive gear with pulley must be deeper inside the machine. I did contact Axminster and they'll get back to me, but I don't know if I can bear the hassle of packing the thing up and sending it off. Will locate the drive pulley myself and risk invalidating the warranty.

silly question, did you try turning up the speed control
can you move the z axis freely if not make sure the power feed is not engaged
also check the chuck has some drag to it

speed is controlled electronically the gear set is for the power feed/thread cutting

Make sure that the 2 speed selector is engaged in a position

Thanks ever so much Dave54. The C3 is very similar apart from bigger andDave54 wrote: ↑Mon Aug 31, 2020 3:34 pm <span class="skimlinks-unlinked">https://www.arceurotrade.co.uk/machineg ... .pdf</span>

Thanks ever so much. It's just what I need. The C3 is just bigger and more powerful. Now I can take it apart and not have to worry about putting it back the right way. Just for those who have the same problem as me, the link I'm referring to is to a brilliant diagram by diagram guide to dismantling the C3 lathe, also applicable to the C2 300.

Hi Bob225. Thanks for your reply. In fact I did not turn the speed right up. I assumed that it nothing was happening when I turned it up to about halfway, then best no further. I did try to check the power feed but I couldn't see how to do it. I'll try again, just to make sure it's not that. Yes, the chuck drags OK. No-one so far has said anything about having to tun a new lathe in, so if there is a fault then perhaps it was already there. Thanks again
