Lubrication tips for a 4400

[Garys Metalworks]

I'm looking for any tips on lubricating a 4400 .
I have found info on greasing the rails but I am not sure about the torch lift station .
Thanks for any help .

Since the lifter station is fairly sealed up it is difficult to get to the lead screw unless you remove the nylon mounting block as well as the shroud. You only need to keep the screw clean and possibly a very light rub down of silicone spray. Too much lubricant and you are going to attract plasma dust which will make the stiction worse.
