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
• traffic
• access
• soil type and condition

Identify Hazards

Identify safety hazards and classify jobsite. See “Classify Jobsite” on page 72.
Jobsite hazards could cause death or serious injury. Use correct equipment and work methods. Use and maintain proper safety equipment.
To Help Avoid Injury:
• 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 - 72 RT120Q 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’ (6 m) to each side of trench 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
Use 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
Crystalline silica dust is a naturally occurring substance found in soil, sand, concrete, granite, and quartz. Breathing silica dust particles while cutting, drilling, or working materials may cause lung disease or cancer. To reduce exposure:
• Use water spray or other means to control dust.
• Refer to U.S. Department of Labor Occupational Safety and Health Administration guidelines to learn more about appropriate breathing protection and permissible exposure limits.
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.

General Operation

Moving traffic – hazardous situation. Death or serious injury could result.
Avoid moving vehicles, wear high visibility clothing, post appropriate warning signs.
To help avoid injury:
• Drive carefully in congested areas. Know machine’s clearance and turning radius.
• Keep attachments low when operating on slope. Drive slowly and cautiously.
EMERGENCY SHUTDOWN: Turn ignition switch to STOP.
1. Turn on lights as needed.
2. Raise backfill blade and all attachments.
3. Release parking brake.
4. Adjust throttle.
5. When operating in low or medium:
• if using the hand control, the foot control will only increase speed.
• any opposing signal from controls causes ground drive to stop.
6. When operating in high, ground drive stops if hand control is moved out of neutral position.
CMW
Drive

Safe Slope Operation

Tipover possible. Machine can tip over and crush you.
To help avoid injury:
• Always operate with heavy end uphill.
• Drive cautiously at all times.
• Never jerk control levers. Use a steady even motion.
• Do not park unit on slope without lowering digging attachment to the ground, returning all controls to neutral position, shutting down unit, and applying parking brake.
Operating safely on a slope depends upon many factors including:
• Distribution of machine weight, including front loading and absence of load
• Height of load
• Even or rough ground conditions
• Potential for ground giving way causing unplanned tilt forward, reverse or sideways
• Nearness of ditches, ruts, stumps or other obstructions and sudden changes in slope
• Speed
• Turning
• Braking performance
• Operator skill
These varying factors make it impractical to specify a maximum safe operating angle in this manual. It is therefore important for the operator to be aware of these conditions and adjust operation accordingly. Maximum engine angle and braking performance are two absolute limits which must never be exceeded. These maximums are stated below since they are design limits. These design limits usually exceed the operating limits and must never be used alone to establish safe operating angle for variable conditions.
Maximum engine lubrication angle – 30° Maximum service brake retarding force – equal to traction of both tracks. Maximum secondary brake retarding force – equal to traction of one track. Maximum park brake holding force – equal to traction of both tracks.
CMW
