Why is this thread still going???
We have already established that you can position the PC switch in the "5.5 position." This does not mean that your PC has a 5.5 speed setting. The motor does not increase its speed,....its still moving at speed 5. When you put it to speed 6, the speed goes up. You can hear and feel the change from 5 to 6. There is no change from 5 to the supposed 5.5. Someone already measured that there was no difference in the machine speed set at 5 and set at the "5.5" setting. If there actually was a 5.5 setting (not just position the dial to where 5.5 would be), you should be able to perceive an increase in machine speed by either sound and/or vibration.
I think some of you are arguing about different things. Those who claim they have a 5.5 setting are saying you can position the switch (with a click) to what would be a setting of 5.5. Those arguing there is no 5.5 setting are saying that there is no increase in machine speed in the "5.5" position. The machine is still moving at the same speed as the 5 position, even though it is on the 5.5 setting. Essentially,.......the machine is on speed 5 or speed 6,......with anything before speed 6 the machine is on speed 5 regardless of the setting of the speed dial (assuming you are past the speed 5 setting).
Are we in agreement here??? If someone's machine actually increases its speed in the "5.5" position, I would like to see video of that, because everyone else seem to know that in the 5.5 position the machine is still moving at speed 5, as there is no perceivable change in the machine speed (as would be supported by the person who measured the machine speed with his device and found no change at setting 5 or 5.5, but a change at setting 6).
