Setting up the Machine for Drilling
1. Using the drive pendant, drive the machine to the
location that you have prepared for it, ensuring that
the front of the machine is the proper distance back
from entry point and the drill frame is in line with the
bore path.
2. Drive up to the location and make sure that all utilities
are located and marked prior to drilling.
3. Move the operator station to the desired angle, switch
the Drill/Drive switch to the Drill position, and raise
the pipe elevators, so that the pipe is resting on the
elevators; refer to
Starting the First Pipe (page
4. Load the first pipe and install the sonde and the drill
head; refer to
Starting the First Pipe (page
5. Place the drill head on the drill frame, and take a pitch
reading using the receiver; refer to the Tracking System
Operator's Manual.
