Guidelines

Follow these guidelines before operating any jobsite equipment:

•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® dealer.

•Replace missing or damaged safety shields and safety signs.

•Use equipment carefully. Stop operation and investigate anything that does not look or feel right.

•Do not operate unit where flammable gas may be present.

•Contact your Ditch Witch dealer if you have any question about operation, maintenance, or equipment use.

Emergency Procedures

Safety - 13

Jobsite hazards could cause death or serious injury. Use correct equipment and work methods. Use and maintain proper safety equipment. 274-050

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.

•Warn people nearby that an electric strike has occurred. Instruct them to leave the area and contact utility.

•Raise attachments and drive from immediate area.

•Contact utility company to shut off power.

•Do not return to jobsite or allow anyone into area until given permission by utility company.

If you suspect an electric line has been damaged and you are off tractor, DO NOT TOUCH TRACTOR. Take the following actions. The order and degree of action will depend upon the situation.

•LEAVE AREA. The ground surface may be electrified, so take small steps with feet close together to reduce the hazard of being shocked from one foot to the other. For more information, contact your Ditch Witch dealer.

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.
