set at "0". I moved it to1 and a half...fine, but do you do anything at the 0 mark? My old little machine has a dial from1-9 or so and pretty much was set somewhere between 3-5. The new electronic one has me a bit intimidated as there is no dealer near and I can't afford to wreck something. The manual just says basically higher/tighter, and lower/looser. Also do you know when ,or if, and for what ,would one go below the "0" mark?? I have so many ideas but just can't seem to get going here.
