We have been collecting rocks for years. Have a huge collection, rocks everywhere. Lots of rivers and creeks in Sonoma County plus not far from the ocean here in California. Which makes for easy rock hounding.
Always wondered what's inside the rocks when the outside is so pretty. Well now I might find out but I need some help!
Recently we purchased a Raytech 18" slab saw at a auction. It had been donated so they had no information. Well it's having a problem staying running, it starts up then shuts down right away. We replace the power relay switch this didn't solve the problem. It also has a micro pressure switch which I have been trying to locate. However not sure if this is our problem.
When I did a search for the Raytech 18" saw, I found this forum. I started to realize we have a true gem of a saw. According to @junsil who stated it was like the Roles Royce of saws. I saw quite a few of you also have this saw perhaps you know what the issue could be? Really excited to get it up and running. I have already reached out to Rick Shaw who is out of the office this week. We would really appreciate all your advice and knowledge to help us. Thanks, Randy and Patty

I'd need more info to even guide your thinking. Could the motor be getting hot when cutting a big rock. How do you restart the motor after such an event. Or is the feed or blade stopping but not the motor. It is a unique saw but still just steel, copper, and diamonds so your problem can be solved. Photos and words are needed, please.

First, welcome to the forum from South Dakota! Second...when I started reading your post and kept seeing the reference to "we"...I thought she'll fit in...she's as crazy as the rest of us! LOL Third...tagging gunsil and Rockoonz for you. I think it's gunsil you're trying to tag.

Welcome to the forum from Central California and congrats on your purchase! I know nothing about your particular saw but some of the troubleshooting is universal. Do you have a voltmeter? The first thing to do would be to check power at the motor when it shuts down. That would tell you if it's the motor or not that's the issue. If there's power there's an issue with the motor. If not then it's one of the controls (switches) or wiring.

Welcome from AZ Like rockbrain said, best to trace the wires from the motor back, using plenty of respect for the electricity. The no touch current sensors are good for the basic check, but a voltmeter will be needed if it's less than obvious. That saw appears to have a separate motor for the feed, does it also stop? If so I would trace from wall plug forward to wherever they split, if the feed keeps running it will be after the split. I lookes at the article that probably got you here and it looks like the saw was made for production cutting. The reverse spin on the saw blade is curious, since no other manufacturer looked at it and copied it I can't call it better, but this saw should be left that way since the vice and everything was designed around it. I have looked at a couple big Raytech saws, but never had one close. AzRockGeek do you have one? catmandewe I'm sure one or 2 have passed through your hands. roy looks like you have a couple of them maybe?

Welcome to the forum. There are a few possibilities, as mentioned, you motor could be shutting down due to over heating. The Raytech has a Ammeter built in, how much current is it drawing before it shuts down? Is the motor outer casing HOT to the touch? In the lower box in front of the saw, there is a power relay and a oil flow sensor on the bottom (White Switch). the oil pressure switch on mine has been bypassed, this switch will detect that you have oil pressure in recirculating system and will shut the saw down if there is no pressure to protect the blade/saw. If you are on FB, in 'Lapidary Equipment Marketplace' there is a 'Files' tab, there is a users file for the saw in there. It will not help with the electrical issue, but is will help out on basic operations.

AzRockGeek I bet they're testing it dry, I would... Oil flow sensor, eh? Got to look at that, want to have one on the drop saw. Must have a relay with a delay to allow it to pressure up before shutting down on start up. Automotive oil pressure switch for sender? rockingaround is that what you're doing? If so I think you have your answer, let us know.

Mine does not recirculate oil, oil just sits in the sump. Maybe it's an oil level switch? If rockingaround has that switch system perhaps he just needs to fill saw with oil for it to work. I know a couple other people/clubs with these saws and have never seen one with the switch/relay system, maybe later saws had it? My ammeter doesn't work but saw works fine. These are the Rolls Royce of 18" saws for sure!

My saw has a pretty low S/N, I wonder if they had too many issues with the oil switch and removed it. Mine is setup for a recirculating oil system.

Thank you so much for all these suggestions to fix our power issue. The saw has not operated or cut since we brought it home. So the motor isn't getting hot and isn't cutting rocks, yet. Going to try some of your suggestions and get back to you. Thanks again

Rockingaround, does your saw have the same system as azrockgeek? If so it will have to be filled with oil or the switch will shut it off. AZ says his switch is bypassed so if you have the same system and saw is full of oil but won't run you may need to do the same modification.

Great news the saw is running! Your knowledge and suggestions were perfect. It was the bad sensor switch we were trying to locate. But once bypassed as suggested, it runs like a dream. Randy was happily cutting slabs today!
Our saw is serial #299.Does anyone know how many saws were produced before they stopped producing them? We really appreciate all your help and comments. I knew when I came across this forum that we would find an answer. You guys are great, thank you all. Sorry for the delay getting back to you, today was a busy day. Thanks again, Patty
