Just bought this saw and the coolant system is confusing me. There's a nipple on the blade guard for (i assume) a water line, but i'm not convinced it's OEM. And there's a big reservoir under the blade that's not particularly easy-access. I'm wondering if this is designed to use oil, and if using water would could cause problems?  I haven't been able to find any documentation for this saw and have no experience beyond tile saws so i'm hoping someone can shed some light. TIA |

Don't know who made those but most were designed for oil. Most days like that have 3 or 4 screws that hold table on. Easiest to unbolt table and remove for initial fill. Cover blade rim, install table and note drip rate at blade guard with saw properly filled. As level drops drip rate decreases. Carefully add oil along blade to restore initial drip rate. Overfilling gives you an oil shower. You could use one of the water soluble coolants or plain water as long as you drain after use and dry blade. Most o
ld metal saws used with water have bearing issues from water penetration.

Thank you John, that's exactly what i needed to know. With the bearings exposed inside the tank i see how it could be an issue so i'll go with oil.
Currently the inside of the reservoir is oily and the bearings are quiet so hopefully i was the first one dumb enough to consider using water ...
Oh and i think these were a mid-60s Sears product.

Yes Sears sold them. All their products were made by others. Loretone, star diamond and other all made products under the Sears brand. I once bought 25 mk145 saws with craftsman name. Leftover stock Mk cleared out.
