Guidelines

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.
• 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.

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 an imminently hazardous situation which, if not avoided, will result in death or
serious injury.
indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury.
indicates a potentially hazardous situation which, if not avoided, may result in minor or
moderate injury.
Watch for two other words: NOTICE and IMPORTANT. NOTICE can keep you from doing something that might damage the machine or someone's property. It
can also alert you against unsafe practices.
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 - Release all controls and turn ignition switch to STOP.

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.

Gather Information

Gather Information
A successful job begins before you dig. The first step in planning is reviewing information already available about the job and jobsite.

Review Job Plan

Review blueprints or other plans. Check for information about existing or planned structures, elevations, or proposed work that may be taking place at the same time.

Notify One-Call Services

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.

Arrange for Traffic Control

If working near a road or other traffic area, contact local authorities about safety procedures and regulations.

Plan for Emergency Services

Have the telephone numbers for local emergency and medical facilities on hand. Check that you will have access to a telephone.
CMW

Inspect Site

Inspect Site
Inspect jobsite before transporting equipment. Check for the following:
• changes in elevation such as hills or other open trenches
• obstacles such as buildings, railroad crossings, or streams
• signs of utilities (See “Inspect Jobsite” on page 58.)
• traffic
• access
• soil type and condition

Identify Hazards

Identify safety hazards and classify jobsite. See “Classify Jobsite” on page 58.
Jobsite hazards could cause death or serious injury. Use correct equipment and work methods. Use and maintain proper safety equipment.
NOTICE:
• Wear personal protective equipment including hard hat, safety eye wear, and hearing protection.
• Do not wear jewelry or loose clothing.
• Notify One-Call and companies which do not subscribe to One-Call.
• Comply with all utility notification regulations before digging or drilling.
• Verify location of previously marked underground hazards.
• Mark jobsite clearly and keep spectators away.
Remember, jobsite is classified by hazards in place -- not by line being installed.
CMW
Prepare - 58 RT55 T4i Operator’s Manual

Classify Jobsite

Classify Jobsite

Inspect Jobsite

• Follow U.S. Department of Labor regulations on excavating and trenching (Part 1926, Subpart P) and other similar regulations.
• 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.
• Inspect jobsite and perimeter for evidence of underground hazards, such as: – “buried utility” notices
– utility facilities without overhead lines – gas or water meters – junction boxes – drop boxes – light poles – manhole covers – sunken ground
• Have an experienced locating equipment operator sweep area within 20 feet (6 m) to each side of path. Verify previously marked line and cable locations.
• Mark location of all buried utilities and obstructions.
• Classify jobsite.

Select a Classification

Jobsites are classified according to underground hazards present.
If working . . . then classify jobsite as . . .
within 10’ (3 m) of a buried electric line electric within 10’ (3 m) of a natural gas line natural gas in sand, granite, or concrete which is capable of producing
crystalline silica (quartz) dust within 10’ (3 m) of any other hazard other
NOTICE: If you have any doubt about jobsite classification, or if jobsite might contain unmarked hazards, take steps outlined previously to identify hazards and classify jobsite before working.
crystalline silica (quartz) dust
CMW
Classify Jobsite

Apply Precautions

Once classified, precautions appropriate for jobsite must be taken.
Electric Jobsite Precautions
se one or both of these methods.
• Expose line by careful hand digging or soft excavation.
• Have service shut down while work is in progress. Have electric company test lines before returning them to service.
Natural Gas Jobsite Precautions
In addition to positioning equipment upwind from gas lines, use one or both of these methods.
• Expose lines by careful hand digging or soft excavation.
• Have gas shut off while work is in progress. Have gas company test lines before returning them to service.
Crystalline Silica (Quartz) Dust Precautions
Cutting, drilling, or working materials such as concrete, sand, or rock containing quartz may result in exposure to silica dust. Use water spray or other means to control dust. If workers are exposed to dust they must wear appropriate breathing protection. Silica dust may cause lung disease and is known to the State of California to cause cancer.
Other Jobsite Precautions
You may need to use different methods to safely avoid other underground hazards. Talk with those knowledgeable about hazards present at each site to determine which precautions should be taken or if job should be attempted.

Special Plowing

Your Ditch Witch equipment allows you to plow four ways: normal plowing, offset plowing (1), coordinated
plowing (2), and crabbing (3).

2. Use blade steer to position blade parallel to direction of tractor frame.
Coordinate Plow
Coordinated plowing can be used to turn a tight circle around a jobsite obstacle or in similar conditions.
1. Move rear steer control to desired position.
2. Slowly move tractor forward.
3. Plow as normal.
IMPORTANT: When coordinate plowing, keep plow blade straight or in the same angle position as rear tires.

5. If bits do not hit diverters:
• Set parking brake.
• Fasten and adjust seat belt.
• Start tractor and adjust throttle.
• Raise saw slightly.
• Use attachment speed/direction control to rotate saw slowly. As it rotates, listen for clicking
sounds. If clicking is present, shut off engine and repeat steps 1-4.

Normal Use
