3) Place the LTW level in the same location on the slider, using the calculated stack of feeler
gages if necessary. Adjust the vial to read level, remember, there is a limited amount of
travel in the vial adjustment, so if the springs start to compress too much, spin the level and
attempt to use the adjustment with it facing the opposite direction. Here we have adjusted
the vial centered (camera angle makes it look slightly to the left).
4) Spin the level 180º and the bubble will be a specific amount off to one side. Raise or lower
the vial accordingly to place the bubble half way between the two readings.
