It's the worst one we have, anyway. I really like the LS14 drop saws, but what a pain it is to pull the thing out of the pan for cleaning. I used to use levers and blocks, but got fed up with that process. If anyone else on here uses a saw like this, you might like the concept shown here.
Rigging took a little while to figure out, but sure makes the job easier. Saw is on old computer desk with casters. Lift the saw out of the pan and roll the table out from under it, then shovel the muck out of the pan.
Have heard others talk about using electric winches for this job, but this is the stuff I had on hand.
I still tend to put off cleaning this one longer than any of the others. It had at least 1/2" of solidified crap in the bottom of the pan this time... .

Yikes!
Be back in a little while when I dig up the easy fix.

First time I posted this was on Bob’s Rock Shop, but that link’s long gone. Since we’re on the subject, here’s an easy way to drain the oil for filtering. I use a couple of ½” pipe rollers to roll the saw off the oil pan. You need a clear area next to the saw on the workbench, and a couple of boards the same 3” height as the oil pan. Lift the front of the saw above the oil pan and put a roller under it, then lift the back end and sit it on the second roller, and roll the saw off the oil pan onto the boards. [When the saw’s about to roll off the back roller, move it the front, or have a third roller handy.] When the oil pan is cleaned out, roll the saw back over it and remove the rollers one at a time. You never have to lift the whole saw this way, and even when you’re lifting the heavy back end with the motor, it’s only a couple of inches. Note: My saw sits ‘sideways’ on the workbench, with the motor on the right-hand side. That’s the way I like to operate it. So when I’m rolling it off the oil pan, it’s a left/right deal. I never bothered installing a drain in the pan because you still want to scrape out the gunk and the sludge. DirtCleaner also went the skyhook route. If you scroll down, you’ll see a fuzzed P-bucket pic showing the saw rolling off the pan. You’ll get the idea, anyway. Also some info on oil recovery. forum.rocktumblinghobby.com/thread/63362/mucking-12

I cleaned out a Lortone oil pan a few weeks ago. Did it in two stages. Poured the lightest muck off the top into the bag first. Most of that filtered through in two hours and I added the rest of the lightest muck. Three more hours and that was through. Five hours total for the lightest stuff. Then I added the heaviest muck while scraping the pan out. That was pretty well done after eight hours. Another eighteen hours yielded only another 1/16” of oil in the bottom five-gallon pail. The two-pail setup is still sitting on top of my furnace where it’s nice and warm. Three weeks has yielded just another 10 ounces of oil. Bottom line: Over 95 percent recovery in less than a day and a half. And if you don’t have a skyhook handy, just roll the saw off the pan. Maximum lift req’d: half a saw ~four inches.

Thanks for the how-to on drop saw cleanouts. Rollers work great. I use the same principle to move a heavy well house cover previous owners built here. I could even use the roller method here by sliding the saw/pan over to the edge of the washing machine pan beneath it. Not a lot of space on that tabletop, but it would work.
I used to lift the saw using a 90-degree flat bar and wood block. Surgery when younger for blown-out L5/S1 disc makes lifting difficult in some positions, so the "monkey and stick" thought processes kick in sometimes. Former ironworker...monkey...it works.
The old come-along, shackle, and lanyards are all souvenirs from ironwork. Had all that crap lying around, so now I only lift the come-along up to the eye bolt.

Great idea Vince. The biggest surprise to me is you have that saw indoors. Or is that a finished garage? My dad uses the same setup to remove the 5th wheel hitch from the back of his truck, only he has a hand crank boat winch on the garage ceiling 👍
I like Rich's idea about the rollers too, but gotta admit I'd prefer the saw above the pan for the oil to drip back into the pan.

Thanks. Winch would be even easier - I just didn't have one of those lying around.
This is a partially converted (previous owners) storage building. We needed shop space, so that's what it became when we bought the place. Six saws, Max-Pro 8 grinder, and 8" arbor in there now, along with storage cabinets and shelves for rough and slabs.
The cut off shower curtains in the photo keep the spray and mist contained okay. It drips down into a washing machine pan under the saw. Still a noisy beast, but it's protected from the weather and I can use it year 'round.

Both systems solve a big problem for a wonderful saw with a crappy design for handling the sludge cleanup. Congratulations. Solving the innumerable mechanistic problems posed by lapidary processes is part of the fun of the discipline.
