• Complete proper training and read operator’s manual before using equipment.
• Contact your local One-Call (811 in USA) or the One-Call referral number (888-258-0808 in USA and Canada) to have underground utilities located before digging. Also contact any utilities that do not participate in the One-Call service. Mark proposed path with white paint prior to contacting One-Call or utilities.
• Classify jobsite based on its hazards and use correct tools and machinery, safety equipment, and work methods for jobsite.
• Mark jobsite clearly and keep spectators away.
• Wear personal protective equipment.
• Review jobsite hazards, safety and emergency procedures, and individual responsibilities with all personnel before work begins. Safety videos are available from your Ditch Witch

Safety Alert Classifications

Safety Alert Classifications
These classifications and the icons defined on the following pages work together to alert you to situations which could be harmful to you, jobsite bystanders or your equipment. When you see these words and icons in the book or on the machine, carefully read and follow all instructions. YOUR SAFETY IS AT STAKE.
Watch for the three safety alert levels: DANGER, WARNING and CAUTION. Learn what each level means.
indicates a hazardous situation that, if not avoided, will result in death or serious injury.
This signal word is to be limited to the most extreme situations.
indicates a hazardous situation that, if not avoided, could result in death or serious injury.
indicates a hazardous situation that, if not avoided, could result in minor or moderate
injury.
Watch for two other words: NOTICE and IMPORTANT. NOTICE indicates information considered important, but not hazard-related (e.g., messages relating to
property damage).
IMPORTANT can help you do a better job or make your job easier in some way.

Emergency Procedures

Emergency Procedures
Jobsite hazards could cause death or serious injury. Use correct equipment and work methods. Use and maintain proper safety equipment.
Before operating any equipment, review emergency procedures and check that all safety precautions have been taken.
EMERGENCY SHUTDOWN - Turn ignition switch to stop position or push remote engine stop button (if equipped).

Electric Strike Description

Electric shock. Contacting electric lines will cause death or serious injury.
Know location of lines and stay away.
When working near electric cables, remember the following:
• Electricity follows all paths to ground, not just path of least resistance.
• Pipes, hoses, and cables will conduct electricity back to all equipment.
• Low voltage current can injure or kill. Many work-related electrocutions result from contact with less than 440 volts.
Most electric strikes are not noticeable, but indications of a strike include:
• power outage
• smoke
• explosion
• popping noises
• arcing electricity
If any of these occur, assume an electric strike has occurred.
