50-14 Operation D7x11 Series II Navigator Directional Drill
SAFETY PRECAUTIONS
Electrocution Avoidance
Electrocution is possible. Serious injury or death may result if the drilling tool strikes an energized power
line. Refer to the operating instructions, and take the following precautions to prevent electrocution:
• Call your One-Call system, and any utility company that does not subscribe to the One-Call system,
before the start of your drilling project.
• Locate underground utilities by qualified persons.
• When drilling operation approaches the estimated location of a utility, the exact location of the
underground installation must be determined by safe and acceptable means.
• Always wear the necessary electrically insulated gloves and boots required for each job function. Refer to
the Preparation section “Personal Protection,” page 40-4.
• Never stand on the ground and touch metal parts on machine or water truck when operating.
• Always keep both feet on the operator console foot platform during operation.
• Never step onto or off the operator platform if electric strike occurs.
• Always test the Strike Alert system before the start of every bore.
• Never operate if the Strike Alert system is not in operation and tested.
• Disconnect from public water supply before drilling where electrical cables may be buried.
DANGER: Contact with the machine while standing on the ground could result in
electrocution if an electrical strike occurs. Do not touch the drill unit or remote fluid mixing
system while drilling or after an electrical strike occurs. See other portions of this manual
regarding procedures and personal protection equipment to avoid electrocution.
