Sieg SC3 CLUNK and no go

Hi guys. When i start the chuck on my sieg SC3 i get a clunk noise, the chuck kicks but nothing else happens. It started as i was drilling a 6mm hole in some steel bar, it went clunk and stopped. Turned it off and back on and it started, ran a couple of minutes and did it again. Now it just goes clunk when i turn the speed control to start the chuck. I always use the speed control knob to stop and start the chuck. Anyone got any ideas?

Only had it a few weeks and am loving it, it is a pretty good machine. Hope you guys can help again.

I have had mine four years and only had a drive belt go once.
Check the gear train, may be one of the gears is misaligned and causing a jam. If all rotates freely and the drive belt is ok, another thing can be the nvr, does the motor run if you depress the start button?

Otherwise may be the speed controller board, but look for a mechanical cause first, it’s cheaper.

Hi Mark,

First check the guard switch to make sure it is not being triggered due to the guard not being closed properly.

If it is not the guard switch, then disconnect machine from power supply, and check if any wires especially the ones which connect to the circuit boards have become loose, for some reason. When checking or removing boards, be careful to not touch the underside of the circuit board near the capacitors, as they do store a good level of energy, to give you a cick, if you are not careful.

Was there any adverse jamming event which took place before you started having this issue?.
Are you using any spray oil/fluid, which could have somehow got into the speed control pot?. There is one person I know of who had, which is why I ask.

If the above checks fail to resolve, call and speak with Ian on Monday after 10am.

Thanks for the replies guys.

Ketan will probably be a couple of days before i get in the workshop again, but i will follow your advice thank you.

Hi Ketan. I followed your advice and the problem is sorted. Thank you so much for your help and advice.

Mark, for the benefit of other Sieg SC3 users, what was the resolution ?

Board damaged due to overload, and belt stripped. New board and belt purchased (Although it wasn't a warranty issue, supplied at subsidised price after mutual agreement)

At present I am working from home.

After Ian (our Sales Manager) read my post, he called me to clarify.

Mark had called and discussed the problem at length with Ian and Brett. He was quite open and honest about the possibility that the damage could have taken place due to overload. Based on the discussion, both Ian and Brett decided to supply the replacement board and belt free of charge on this occasion, and Mark took their advice about working within the limitations of the machine. Ian and Brett requested Mark to keep the details of the solution confidential, as every problem is dealt with on a case by case basis. Decision taken by them for another person may be different.

My apologies for incorrect post.

As always, service from Arc Euro, above and beyond!

No wonder they are top of my preferred supplier list, although, at my age, Ketan will never get rich on my purchases!

That's OK Ketan, I won't tell anybody else. Thanks for the correction, even better support.

Ketan, could You send some of Your Minions over here across the pond to teach service to the Companies We have here?

Lol. There are times when my team and I also get it wrong, and times when we disagree with a customer. The customers who feel we have done wrong have a different opinion of our customer service.

We are a small business. Companies on your side of the pond are around five times+ bigger than us, so experiences of customer service good and questionable will be more amplified.

My personal experiences have been related to retail stores during a visit to New York some twelve odd years ago, where I found the people working in stores - big and small to be very helpful. During my stay there I also visited Travers where the staff were very helpful and friendly. I also meet the then owner of Victor Machinery, who showed me a paper catalogue issued by his grandfather I think, back in 1940s. He showed me around his place and introduced me to his great team. I recall being amused watching them use gum paper tape to pack cartons and thinking it was old fashioned, or possibly the American way. ARC adopted the same idea some three years ago.

I also have a chat now and then with Chris Wood - LittleMachineShop. I find him and his team to be very helpful too.

I did learn a few good things from my visit, as I am sure we all do from new experiences. I am sure that there must be more good companies there too.
