8. Operating Precautions
1-10
WARNING These instructions should be strictly followed for the safety of you, others and your machine.
• Undermining a cliff is dangerous as it may cause a rockslide or landslide.
• Undercutting the machine is dangerous as it may cause a cave-in, resulting in the machine over-
turning and falling into the excavation.
• Working in the vicinity of overhead electric power lines presents a very serious hazard and special
precautions must be taken. For purposes of this manual you are considered to be working in the
vicinity of overhead power lines when the attachment or load of your excavator, in any position,
can reach to within the minimum safe distances shown below.
• The following procedures are effective in preventing accidents or injuries.
1) Wear shoes with rubber or leather soles.
2) Use a signal person to warn the operator when the machine is getting too close to a power line.
• If the machine should contact a wire, the operator must not leave the operator’s seat.
• When working near power lines, caution all ground personnel to stand clear of the machine.
• To determine the transmission voltage at the working site, contact the electric utility concerned.
