Using Drill String Guide
Use drill string guide to align drill string as it enters the
soil. When using drill string guide, follow these
guidelines:
• Use only approved Ditch Witch drill string guide
(p/n 179-737).
• Stand only on the left side of the approach trench.
• Keep drill string guide at least 3’ (1 m) behind bit.
• Use drill string guide to control only the first 5’ (1.5
m) of the bore path.
• After drilling 5’ (1.5 m), stop unit and remove drill
string guide.
• Do not use drill string guide during backreaming or
any time the drill string is being pulled back.
IMPORTANT: For location and description of drilling switch see page 36.
EMERGENCY SHUTDOWN: Release drilling switch and turn ignition switch to STOP.
NOTICE:
• Drilling too quickly causes bit to drift off course and may bend drill rod. After bore path is
established, speed may be slightly increased.
• If drill rod starts to bend, stop forward movement of unit and back the unit slightly until rod
straightens. Do not drill with bent rod.
• If drill rod hits an obstruction, rotate drill string counterclockwise to back up slightly.
Turning shaft will kill you or crush arm or leg. Stay away.
NOTICE: Keep everybody at least 10’ (3 m) away from drill rod during operation. Do not
straddle trench or drill rod while drilling.
