Speed control dial

The dial for my speed control seems to be slipping. I go from fast speeds to slow and gradually have to go way past the slow mark to get to the slowest speed. Ant tips?

1) Make sure your sheeves are oiled (motor and idler)
2) use a flashlight and take a look at your quadrant teeth (ie: the 'porkchop"). If those are bad then replace.
3) take your speed dial off and check the gear on the back. If messed up - replace.

4) Check to see if the set screw is loose causing the knob to slip on the shaft(turns the outer dial without actually moving the shaft////sheaves).

and to take that great advice a little deeper..
Pull it off and look at the shaft where the set screw seats, the can they get gouged out real bad sometimes when the screw is left loose for extended periods.
That shaft can also bend. Luckily new ones are available cheap from SS.

Notice there is a hole on the shaft that the set screw should seat into(sorta like a deeper, round 'flat').

Turn the speed up to high, turn off the SS and unplug it. Remove the rear cover. The oil hole will be close to the sheave, turn the shaft till the hole is on top. Then use a wide blade screw drive to open the spring so ya get to the hole.

This is how I do it on my "A" Headstock with no maintenance hole on the back.
speed to high
unplug
put in drill press mode.
remove belt cover.
locate oil holes and ten drops per hole.
let sit over night.
The next time I use it plug back in while still uncovered in drill press mode. (Make sure anything that can get caught in the moving bits is well clear) Run through the speeds to make sure it's working smoothly and oil is up and down the shafts.
This gives me the opportunity to inspect for damage or cleaning that may be required as well.
Button it up.
Done!

Drill press position is the key here. Just need to oil the shaft and let the oil run down. Also put a few drops in the hole.
To test the quality of lubing put the headstock in normal (sawing) position and pull the outer sheave out by hand. A few pulls will let you know if the oiling has been successful.
P.S.drill press position is also good for oiling the control sheave. This way oil will surely find its way to that little bearing on the end.
