make any required directional adjustments as drilling progresses.
D. After the reamer has followed the rods to the machine end and the bore has
reached the required diameter, the product pipe shall be carefully pulled
through the bore to the required tie-in point.
E. Barricades and warning signs shall be erected to keep unauthorized
