NOTE: TEC controller outputs for raising and lowering
the cutting units (S1, S2, S3 and S4) are timed by the
controller. This timing requires a momentary input by the
operator to initiate the output and then keeps the ap-
propriate solenoid coils energized long enough to com-
plete the desired machine function.
