The mobile caster on the 36-725 looks dirt simple. It seems to me that it worked flawlessly at first, but for the past year or so, it has been giving me fits. I can’t see anything wrong with it, but when I try to move it, the foot lever doesn’t raise it up, and if I attempt to roll it around anyway, the wheel gets cocked under it, as shown in the photo below:

Has anybody else experienced this problem & have a solution? My shop is small, and I need to be able to move the saw around.

Looks like you pushed it too far down while the wheel was sideways. Lift the saw up and pull the pedal all the way up and put wheel inline with pedal.

I just looked at my saw and there is a point where if the wheel is turned just right it will catch on the bracket and twist under allowing the pedal to go all the way down as in your picture. Make sure the wheel is straight pointing forward or backwards before pushing down the pedal.

I didn’t catch that it cocks that way when lifted and trying to roll around. Have you checked that the wheel is not loose on the bracket plate? Has the rubber wheel worn down to where it’s not lifting. Could be you just need to do some adjusting. Check the swivel bearings for slop/

Yes, I’m sure that’s what happened… but it always does this. I’m pretty sure that it never used to.

I think that I didn’t explain the problem very well, so I put together a little video that might help.

https://youtu.be/WfvZbFnZuR8

There are several issues. Pressing the pedal does nothing. It doesn’t lift the machine. The cam portion of the pedal doesn’t even touch the caster base.

If I pull the machine towards me, the wheel straightens out, but if I push it, the wheel tilts and tucks under, like shown in the photograph in my original post.

Does the other wheel behave itself?
Is the lever plastic?
Is there a wheel height adjuster?
Have you removed the bolt to see if the hole has distorted?

Looking at the video its obvious that the cam is not engaging which seems like a mangled hole.

Thanks for the reply, Ducky.

There is only one caster.
The lever is steel.
There is no adjustement
Nothing seems worn in the least.

Bucky, have you tried pumping the tyres up… those plastic crappy tires won’t pump up but our Australian tyres will.

Might there have been a plate between the top of the wheel base and the cam? Try some steel or some hardwood under the cam and see it that lifts…

It appears the two feet are adjusted to far out. The feet on my saw are adjusted to where the bottom of the tube leg is no more than about 3/8” off the floor. The pedal only has about a 1/4” or so of lift. Screw the feet in to lower the leg.

That was it, totally! I feel kind of stupid for not figuring that out myself, but since I never deliberately changed them, (and had forgotten that they were even adjustable) it never entered my mind. Thanks for the 10 second fix!!!

The video was a big help to see what the problem was. I remember how I had to adjust the feet all the way in and then turn them out to get rid of any wobble in the saw due to uneven floor. You don’t have a lot of adjustment leeway in the feet because the pedal doesn’t have a lot of lift distance and once you adjust the feet too far out the pedal doesn’t have enough travel to lift the saw.

As the missus says… I’m trying… very trying.

I would add, if you haven’t done so already, once the levelers are adjusted, lock them down from the top with an Allen wrench. I neglected that on initial assembly and vibration “readjusted” them over time.

That is probably what happened to me as well, which is why I was puzzled about how it used to work, and then suddenly stopped. I checked a little bit ago and see that one of the locking plugs is missing.

I have a Delta quite a few years older than your newer unit a 36-979 and it has the same style wheel, and I also have a 15” planer on a Delta stand and it too shares that wheel design. I had problems with the planer first, it’s older too, and the saw several years later, and I jumped right to my “fix”

On the planer it was all wonky like yours with no apparent problem, save it kept folding under, and would not roll for squat. I spent a lot of time fiddling, and finally I just sprayed the wheel with some Kroil. Next day it was fixed. I’d have sworn it was clean, and didn’t need any lube, but after the Kroil it was all back to normal.

After I moved the planer, where it had been was quite the pile of gunk where the wheel had been. Evidently the mix of wood dust, and whatever was there, and the Kroil boiled it out. As soon as I had trouble with the TS, I did the same with Kroil, and fixo-stupido I was all better with that too.

Ever since then I get a little hinky when I only have one can of Kroil left. :-)

Hope it works for you too.

Have had all kinds of issues with three wheeled mobile bases. They absolutely stink IMHO.
Have a version from Rockler that does same thing as your TS.

The design has three big weaknesses:

1) If wheel is junked up and does not roll smooth, it will either folds under itself, or will not turn well. Needs to cleaned and lubed regularly as Steven suggests

2) The total amount of lift is less than 3/4”. So any adjusting legs in front have to be short. If too long they snag, or lift the front and allow the wheel roll under the bracket; as you have learned.

3) Hinged caster plate does not have any thing to limit the downward movement. This makes it easy for the wheel to tuck under the bracket and get stuck rolling on surfaces that are not level. Mine will constantly fold under neath the bracket, with wheel stuck in groove as it rolls over a crack stop groove in concrete (unless rolling straight over crack at 20mph).

TBH – The common bench casters have the same hinged caster plate design, and drive me crazy too. I know the issue is my uneven floors and the building code mandated 3/4” deep crack stops in concrete, if only the castor plate had bottom stop to prevent the dreaded roll under. Only solution I have found is bigger wheels, and higher lift distance on mobile bases. Sure wished the folks making these stupid casters would read the forums for product improvement ideas, as they do nothing when you email them. Sigh

Thanks for letting me vent.
Best Luck.
