HT25 - SAFETY 21EMERGENCY PROCEDURES

EMERGENCY PROCEDURES

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.

Electric Strike Description

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. Almost one-third of 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.

Crystalline Silica (Quartz) Dust

Follow these guidelines when trenching, sawing or drilling through material that might produce dust containing crystalline silica (quartz) dust.

1. Know the work operations where exposure to crystalline silica may occur. Be aware of health effects of crystallline silica and that smoking adds to the damage.

2. Follow OSHA (or other) guidelines for exposure to airborne crystalline silica. Participate in air monitoring or training programs offered by employer.

3. Be aware of and use available engineering controls such as water sprays, local exhaust ventilation, and enclosed cabs with positive pressure air conditioning.

4. Where respirators are required, wear one approved for protection against crystalline silica-containing dust. Do not alter respirator in any way. Workers using tight-fitting respirators cannot have beards/mustaches which interfere with respirator’s seal to the face.

5. If possible, change into disposable or washable work clothes at jobsite; shower and change into clean clothing before leaving jobsite.

6. Do not eat, drink, use tobacco products, or apply cosmetics in areas where there is dust containing crystalline silica. Wash hands and face before eating, drinking, smoking, or applying cosmetics outside exposure area.

7. Store food, drink, and personal belongings away from work area.

Other Jobsite Precautions

You may need to use different methods to safely avoid other underground hazards. Talk with those responsible for hazards to determine which precautions should be taken or if job should be attempted.

HT25 - TRENCHING 51OPERATING TIPS

OPERATING TIPS

• Avoid using badly worn teeth. When replacing teeth, maintain original pattern. Use Ditch Witch replacement teeth.

• Operate engine at full throttle.

• Do not make sharp turns. Lower boom to full depth when turning.

• While trenching, steering is best accomplished by feathering one track control at a time, rather than both together.

• If an object becomes lodged in chain, move digging chain clutch to neutral and raise boom slightly. If object must be removed manually, turn engine off.

• Before operating with rock chains, check bits for free rotation. Tap bits lightly with a hammer and turn by hand. If bits are stuck, remove and clean packed soil from bit block.

• Carbide bits are recommended for cutting abrasive material, such as sandstone or frozen sands or gravels.

OPTIONAL EQUIPMENT

Chain

A variety of chains, teeth, and tooth patterns are available to provide efficient digging at any jobsite. For more information, contact your Ditch Witch dealer.

Trench Cleaner

Trench cleaners remove spoils from the trench floor. For more information about the mechanical trench cleaner available for use on the HT25, contact your Ditch Witch dealer.
