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