Using the Guidance Screens
...Using Guidance and Coverage Area Recording
Important - When using a straight AB line
After a straight AB line has been set,
when working on T:1 it is important
that the guidance line is followed on
the screen and not the marks from
the work done whilst setting the
guidance line.
N.B. There maybe significant over/
under lap between the first and
second runs, but if the guidance line
is followed the remaining runs will be
straight and equally spaced.
Important - When using a curved AB line
It is important to use the longer edge of the field when setting a curved AB line to
ensure the guidance line is visible from the one side of the field to the other.
