5.16 Eccentrics adjustment, belt tension
After removing the belt, it is necessary to align the eccentrics.
Put the belt back on, tighten it with the belt tightening wheel (2), and check that the arrows at the
end of the shafts (1) are pointing towards each other. See figure below.
If the marks are not aligned like in the figure, it might be necessary to move the belt a notch or two
on one of the wheels. This is done by loosening the belt tightening wheel (2) again, and then lift the
belt up from the big wheel and move it a notch on the wheel. Then tighten the belt.
