smoke

•

explosion

•

popping noises

•

arcing electricity

If any of these occur, assume an electric strike has occurred.

Prepare Jobsite and Equipment

Drill - 101

Prepare Jobsite and Equipment Approach Trench (1) 1. Mark path where you intend to drill.

2. Dig an approach trench (1) along the intended bore path.

IMPORTANT: The approach trench should be at least: •

deep enough for pipe to lay flat and enter soil at correct angle

•

20’ (6 m) long

•

4” (100 mm) wide

Target Trench (2) 1. Select a completion point for the drilling project.

2. Dig a target trench (2) across the anticipated completion point.

IMPORTANT: The actual length of the target trench depends on soil conditions and length of pipe sections. Make it deep enough for drill bit to enter slightly above the trench floor.

Drill Pipe and Equipment 1. Assemble at least 20’ (6 m), but not more than 30’ (9 m), of drill rod.

NOTICE: More than 10-15’ (3-4.5 m) of drill rod out of the trench increases the tendency of drill rod to bend.

2. Install drill bit to the cutting end of the drill string.

3. Put drill string in approach trench.

4. Move tractor to the approach trench and align the drilling attachment with the intended bore path.

5. Turn off engine.

6. Attach drill string to drilling attachment.

EMERGENCY SHUTDOWN: Release drilling control and turn ignition switch to STOP. 1. Start tractor’s engine and begin clockwise (forward) rotation.

2. Slowly advance tractor while maintaining clockwise rotation.

NOTICE: •

Drilling too quickly causes bit to drift off course and may bend drill rod. After bore path is established, speed may be slightly increased.

•

If drill rod starts to bend, stop forward movement of unit and back the unit slightly until rod straightens. Do not drill with bent rod.

•

If drill rod hits an obstruction, rotate drill string counterclockwise to back up slightly.

Using Drill String Guide Turning shaft will kill you or crush arm or leg. Stay away.

NOTICE: Keep everybody at least 10’ (3 m) away from drill rod during operation. Do not straddle trench or drill rod while drilling.

Use drill string guide to align drill string as it enters the soil. When using drill string guide, follow these guidelines: •

Use only approved Ditch Witch drill string guide (p/n 179-737).

•

Stand only on the left side of the approach trench.

•

Keep drill string guide at least 3’ (1 m) behind bit.

•

Use drill string guide to control only the first 5’ (1.5 m) of the bore path.

•

After drilling 5’ (1.5 m), stop unit and remove drill string guide.

•

Do not use drill string guide during backreaming or any time the drill string is being pulled back.

CMW

RT55 Operator’s Manual Add Rod

Drill - 103

Add Rod 1. Stop drilling attachment.

2. Back up tractor 6" (150 mm) to loosen drill rod in ground.

3. Disconnect drill rod from drilling attachment.

4. Move tractor away from bore.

5. Add one drill rod to continue bore.

Backream After drill bit enters target trench, the bore hole may be enlarged by changing the drill bit to a backreamer and drawing it back through the initial bore.

1. Turn tractor ignition switch to STOP. 2. Replace drill bit with backreamer.

3. Start tractor engine and begin clockwise rotation.

IMPORTANT: Always rotate clockwise during backreaming. Rotate counterclockwise only to dislodge a dry bore bit or reamer that has siezed in the bore hole.

4. Slowly back up tractor while maintaining rotation.

5. When backreamer exits the bore hole, stop rotation immediately.

IMPORTANT: •

Do not try to increase hole size too much in one pass. Several passes using successively larger reamers will save wear on machine.

•

During backreaming, keep drill string straight. Sharp bends in the drill rod at the motor coupling can cause rod failure.

2. Move cruise control rpm control to arrow at center.

3. Move cruise control selector to AUTO. 4. Following procedures on page 79, begin trenching to desired depth.

5. When desired depth is reached, ensure throttle is fully open.

6. Slowly move ground drive control fully forward.

7. Slowly adjust cruise control rpm control to match digging conditions.

IMPORTANT:

8.

•

In harder digging conditions, higher cruise control rpm setting may improve digging performance.

•

In easier digging conditions, lower cruise control rpm setting may increase ground drive speed.

When finished digging, move ground drive control to neutral, then move cruise control selector to MANUAL. Incorrect procedures could result in death, injury, or property damage. Learn to use equipment correctly.

NOTICE: Moving cruise control selector to MANUAL with ground drive control out of neutral will cause machine to immediately move in the direction of the ground drive control. This can result in injury or damage.

9. Allow chain to dig itself free before stopping attachment.

Trench Depth Meter

Trench Depth Meter Trench Depth Meter (TDM) is an optional electronic system for measuring and recording trench depth.

TDM also displays productivity and distance while trenching. Two lines of information are displayed on the LED screen. If the system detects error conditions, diagnostic codes will be displayed on the second line.

IMPORTANT: For more information about TDM see the TDM Operator’s Manual (p/n 054-117).

Chain, Teeth, and Sprockets Chain and Tooth Maintenance •

Always replace sprockets at the same time you replace the digging chain. Sprockets and chain are designed to work together. Replacing one without the other will cause premature wear of the new part.

•

Keep digging teeth sharp. Using dull, worn teeth will decrease production and increase shock load to other trencher components. It can also cause chain stretch, which leads to premature chain wear and failure.

•

Maintain the proper amount of tension on the digging chain. Overtightening will cause chain stretch and loss of machine performance. For correct tightening procedure, see page 143.

•

Use the tooth pattern most appropriate for your digging conditions. If you move to a different soil type, contact your Ditch Witch dealer for information about the most effective chain type and tooth pattern.
