I have the table top off. I have sprayed the worm and raising gear with carb cleaner then a spray grease. I have raised and lowered it 15+ times. It is still a two hand raise and a strong one hand to lower. The tilt was a little difficult but I cleaned and greased it and it is very easy. The saw sat about 5 years with using it maybe once a month for a cut or two.

Any input for getting the raising and lowering to work easier?

I’ll be watching this thread for ideas – I’m having exactly the same problem.

First thing I’d do is make sure the lock mechanism is disengaged and not sticking, as that is the easiest.

The manual has a section about binding that might be relevant:

Blade Raising Mechanism Adjustment

If binding occurs, clean off all sawdust and pitch buildup and re-lubricate with a good non-hardening grease. If binding continues, check the fit-up of the worm and worm gear segment. The worm must be centered with the worm gear segment. If it is not centered, loosen the saw raising arm set screws, move the arm as required, and re-lock the set screws. See Figure 22.

If the saw raising arm has been re-located, the table may have to be realigned so as to provide clearance between the saw blade and table insert slot. The splitter will also have to be realigned.
NOTE: The saw arm setscrew must be tight to avoid the possibility of movement which could cause the blade to hit the insert.

Cheers,
Brad

PS: the last thing I’d be using on that saw is carb cleaner

Pull the center locking knob out and spray PB Blaster inside the center hole, sounds like the key is stuck.

Bruce, search this topic here on LJ because I seem to recall reading about this issue previously. FWIW
