Setting a clicking-type torque wrench
How do I do it? On the handle, there are two sets of numbers 0-9. On the shaft, there are marks for inch lbs going up 120, 240, etc up to 840. On the other side of shaft are lines to set m-kgs, I'm assuming that's what the other set of 0-9 on the handle are for. So a half revolution of the handle (10 units) sends it up one notch on the shaft (increments of 120 lb-inches). So I add 12 inch lbs for every notch on the handle that I turn? That makes the most sense but seems pretty weird.

On mine I pull on the bottom of the handle and turn the knob until the torque amount that I want is on the red line. Then I just torgue till it clicks and I repeat this a couple of time. For reference I have a craftsman but not sure exactly which one. I hope this helps.

the handle where you turn has 0-9....thats the ones digits.
so to tighten to 85....keep turning till 80 gets to the handle, then turn till the 5 on the handle is at the arrow.

I believe that I have a similar torque wrench.
The markings between 0 and 9 are for setting a torque between the main markings on the handle (eg. adds that many in-lbs to the nearest handle marking).
On the bottom of the handle should be a lock nut.
Steps:
1) unscrew lock nut so that it is loose
2) lets say you want 125 in-lbs of torque
3) turn the handle until the 0 lines up with the centerline at the 120 in-lbs marking
(you are now set for 120 in-lbs)
4) turn the handle (to the right) until the 5 lines up with the line down the middle of the markings
(you should now be set for 125 in-lbs)
5) tighten the lock nut on the bottom of the handle
(you are now set for this amount of torque)
However, typically I would set the wrench at about half (say 60 in-lbs), tighten all the nuts and then reset the wrench to the desired setting (say 125 in-lbs) and then retorque all the nuts.
For lug nuts, you should try to torque them in a criss cross pattern.

Ok, maybe, but then as I keep turning when the handle gets to "0" again, it is lined up with "240" and NOT "130". That's why I was thinking that each notch on the handle is actually 12 inch pounds and not 1.
My theory is that your torque wrench is actually calibrated in ft-lbs (1 ft-lb = 12 in-lb) but marked in in-lbs so your actual range of adjustment is 120 to 840 in-lbs or 10 to 70 ft-lbs.
This makes sense since 120 to 240 in-lbs is 10 to 20 ft-lbs and that would make each marking 1 ft-lb.
If you really need in-lbs then I would recommend buying a new torque wrench with in-lb markings that will allow you to increment by a single in-lb.
