• 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

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

Arrange for Traffic Control

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

Prepare for Working Near Existing Utilities

If jobsite may contain electrical lines, wear protective boots and gloves meeting the following standards:

• Boots must have high tops and meet th e electric hazard protection requirements of ASTM F2413 or ASTM F1117, when tested at 14,000 volts. Tuck legs of pants completely inside boots.

• Gloves must have 17,000 AC maximum use voltage, according to ASTM spec ifica tio n D12 0.

If working around higher voltage, use gloves and boots with appropriately higher ratings.

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

MV800 Operator’s Manual Prepare - 33

Inspect Jobsite

• Follow U.S. Department of Labor regulations on excavating and trenching (Part 1926, Subpar t 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 working. 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

• Mark location of all buried utilities and obstructions.

CMW

Prepare - 34 MV800 Operator’s Manual

Prepare Jobsite

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

To help avoid injury:

• Classify jobsite as electric if jobsite classification is in question or if the possibility of unmarked electric utilities exists.

• Expose lines by hand before digging.Cutting high voltage cable can cause electrocution.

• All vegetation near operator’s station must be removed. Conta ct with trees, shrubs, or weeds during electrical strike could result in electrocution.

Prepare Excavation Point

274-050

• Clear the area to be excavated. Remove rocks or branches too large for vacuum hose.

• If excavating fluids while drill string is moving, clear area of trees, shrubs, and weeds.

• Select a solid area to stand on while excavating.

Determine Tank Fill Level

Use these reference charts to help determine how full of various ma terials the va cuum t ank ca n be without overloading trailer. Exceeding the maximum fill level will overload the trailer.

Never exceed the trailer capacity. You can exceed the vacuum tank lifting capacity if you drain the tank down to the lifting capacity before lifting tank.

To use these charts, first select the appropriate table based on trailer and vacuum tank size. Next find the material being excavated. If the material being excavated is not listed, find a material with similar density. Then, determine the maximum fill level based on the amount of water in the water tank.

IMPORTANT: For all materials, the vacuum tank should be no more than half full when lifting the tank.

Explosion possible. Serious injury or equipment damage could occur.

Follow directions carefully.

To help avoid injury:

• Use a single 12V maximum source for charging. Do not connect to rapid chargers or dual batteries.

• Use caution and wear personal protective equipment such as safety eyewear, when charging or cleaning battery.

• Keep sparks, flames, and any ignition source away from batteries at all times. Internal contents are extremely hazardous. Leaking fluid is corrosive. Battery may be explosive at higher temperatures.

• NEVER lean over battery when making connections.

• Do not allow vehicles to touch when charging.

• Do not attempt to charge a battery that is leaking, bulging, heavily corroded, frozen, or otherwise damaged.

• NEVER short-circuit battery terminals for any reason or strike battery posts or cable terminals.

• Refer to MSDS for additional information regarding this battery.

Before You Start

Electronic components can be easily damaged by electrical surges. Jump starting can dam age electronics and electrical systems, and is not recommended. Try to charge the battery instead. Use quality large diameter jumper cables capable of carrying hig h currents ( 400 amps or more). Cheap ca bles may not allow enough current flow to charge a dead/discharged battery.

Read all steps thoroughly and review illustration before performing procedure.

IMPORTANT: Some equipment may have a positive jumper cable terminal (1) located externally. If so equipped, connect red positive (+) jumper cable clamp to terminal.

4. Connect the other red positive (+) jumper cable clamp to positive (+) post of battery (A) in the service vehicle.

5. Connect black negative (-) cable clamp to negative (-) post of battery (A) in service vehicle.

6. Connect the other black negative (-) cable clamp to the engine or frame ground on the disabled vehicle, at least 12” (305 mm) from the failed battery, as shown.

7. Operate service vehicle engine at 1500-2000 rpm for a few minutes to build an electrical charge in the failed battery.

8. Stop engine in service vehicle.

9. Remove jumper cables from the service vehicle, black negative (-) clamp first. Do not allow clamps to touch.

10. Remove black negative (-) cable clamp from the disabled engine or frame ground first.

11. Remove red positive (+) cable clamp from the disabled vehicle positive (+) battery post last.

12. Reconnect machine controller and try to start disabled vehicle.

If the disabled vehicle did not start, check for loose or corroded battery cable connectio ns. Poor connections will prevent current from charging the failed battery. Clean terminals and posts if necessary and repeat steps above.
