drill string as it enters the soil. See “Start Bore with Drill String Guide” on page 63.
2. Start engine and set to low throttle. See “Start” on page 40.
3. Operate drilling attachment controls to start clockwise rotation.
4. Slowly move machine forward while maintaining rotation:
• When length of bore is more than 5’ (1.5 m), you may carefully and slowly increase speed.
• Always use lowest speed necessary.
5. Carefully monitor progress of bore:
• If rod section starts to bow, stop forward movement of machine and back machine slightly until rod
straightens.
• If drill string becomes blocked, rotate drill string counterclockwise to back up slightly.
6. When drill bit enters target trench, stop rotation immediately.
Rotating shaft will kill or seriously injure. Stay away.

• Keep everybody at least 10’ (3 m) away from drill string and machine.
• If a person enters the danger zone, use emergency shutdown.
• Wear close-fitting clothing and the applicable personal protective equipment.
