I guess I do this a little differently. Maybe it's the same, but the words just get in the way.
1. Raise the little lever on the bottom with your right foot.
2. Depress the foot pedal with your left foot and push down on the head release lever with your right hand. The tension head will lock into "tension set" mode.
3. Set tension with the knob. Self-explanatory.
4. Depress foot pedal and push up on the head release lever with your right hand. You'll feel a click. Release the foot pedal. The tension head is now back in ready position.
5. Lower the little lever on the bottom with your right foot.
6. For good measure, push down on the head release button while using the foot pedal, putting the head and all the springs through a full range of motion at its new tension.
This is what I was told:
You have to switch the lock at the bottom upwards when the tension head is locked in the forward position and the pedal is below horizontal.
After switching the bottom lock upwards, push the pedal a little bit downwards and push the upper release knob down. Now let the pedal come up until it hits the bottom lock and the scale line is shown behind the scale window.
I think we're saying basically the same thing.
