Distance between the frame triangles.
Measure the distances between the triangles, as shown above, on all three sides o the
rame.
Position of the nuts on the outside of the frame.
Now adjust the distance between the triangles by turning the nuts on the rame vertices until
all distances are exactly the same. Make sure the triangles are as ar out as possible, as
shown above. The distance between the bolts should be around 260 mm.
