I just received my new trim saw. I got the Rock Rascal model J. and I have some dumb questions. I probably could have gotten the answers from the owners manual or instruction book but the saw arrived without such paperwork.
Dumb question# 1: Does this saw use water or oil as a coolant?
Dumb question# 2: How do you get to the coolant tank to fill it?
Dumb question #3: If this trim saw uses oil as opposed to
water, after I cut out my templates from my slabs how well do I have to clean the free forms before I can grind them on my diamond wheel machine? Is oil something that one does not want to get on their diamond wheels? I know that all of the really big slab saws use oil I just assumed that the small trim saw use water. I guess I was getting confused with the tile saw that I originally was considering.
Thanks for the feedback
Stu

Water is normally used on 8" and smaller saws. Filling is either by pouring coolant on the table 'till the blade picks it up, or the table can be lifted after removing one flathead screw located directly over the shaft, and about an inch in from the outer edge of the table. On our oil-cooled saws, we wash the cuts in a Dawn dishsoap and warm water mix, scrubbing with a brush. Works for us. The warm water just feels good.

Oil is not necessary in a 6 or 8 inch saw, but anything larger should use oil.
I have added a rust inhibiting additive to the water like Lube cool 4800. i recently learned about using automotive windshield washer fluid, cost a lot less. I have compared, and IMO a saw also cuts faster with less blade wear when using an additive.
When I cut slabs with one of my larger saws I drop them into a tub with kitty litter , then transfer them to a bucket with degreaser and water.

Water is ok for most stones as long as they're not too heat sensitive like Opal.

Thanks rockoonz for adding the info about rust inhibitor, I neglected it last night. We don't run our trim saw much, generally run soluble oil mix then drain and dry after use. Thnx for washer fluid tip, going to give it a run. Do you cut it or run it straight?

I have a Rock Rascal 6" trim saw and I use Lapcraft tool--cool, coolant concentrate diluted I'd send a pic of the label if I knew how to attach it.

Nope, they are sealed.
