5. Attach the required quantity of drill stem segments to
the Hydra-Borer and lower drill stem into starting
trench so that the drill stem passes through the guide
rings on the guide anchor assemblies.
6. To level the drill stem, place the level frame over the
drill stem at a point between the two guide anchors.
Use the level gauge on the level frame to determine if
the drill stem is level. If the drill stem is not level, use
the tube adjustment locks on one or both of the guide
anchor assemblies to slide the guide anchor tube(s).
When the level gauge indicates that the drill stem is
level, tighten the tube adjustment lock(s). When the
drill stem is level remove the level frame from the drill
stem.
