Operation Important: Use only Toro approved attachments. Other attachments may create an unsafe operating environment or damage the traction unit. Note: Determine the left and right sides of the machine from the normal operating position. Understanding Horizontal Directional Drilling Horizontal directional drilling is a process used for drilling a horizontal bore through the soil and under obstructions such as roads, buildings, bodies of water, etc.
Gathering Site Information 4. Drill the bore. You drill the bore in 3 stages: Planning the Initial Route A. Entry In the entry phase of the bore, you push the drill bit and head into the ground at an angle of up to 16 degrees. After pushing in one or more pipes, you begin drilling down and forward until you reach the desired depth or depth-gauge hole (if used). B.
– Electrical power lines DANGER Contacting underground hazards with the machine while drilling or reaming can cause explosion, electrocution, breathing problems, severe trauma, and death to you or bystanders. DANGER Drilling into an electric power line will cause the machine to become electrified and may electrocute you or any bystanders. – Ensure that all personnel at the job site wear personal protective equipment including a hard hat, eye protection, and hearing protection.
– Crystalline silica and other dust If you will be drilling through or cutting concrete, sand, or other substances that create dusts or fumes, you need to ensure that you and all workers wear breathing protection to protect your lungs from the dust.
Planning the Bore Path Before setting up the job site, you need to plan the bore path, including the following: Figure 51 1. Bore entry 4. Obstacle 2. Beginning-of-bore-at-depth point 5. End-of-bore-at-depth point and bore exit 3. Bore depth • Bore entry needed for steering the drill to the surface, typically 9 to 15 m (30 to 50 ft) from the end-of-the-bore-at-depth point. This is where you setup the machine and the drill bit enters the ground.
1 g021765 Figure 52 1. 20 cm (8 inches) This flexibility is often rated in materials as a minimum bend radius, which is the radius of the circle formed if the material or pipes, connected together, were bent to form a giant circle. The minimum radius of a circle made with the pipe used with this machine is 36.6 m (102 ft). 1 3 2 • Entry pitch The entry pitch is the angle at which the machine enters the ground.
Note: The depths given in the following table are for 3 m (10 ft) of combined drill head and pipe. As you steer up, the pitch of the steered section will change and can be monitored with the receiver. Use the following table to identify how many lengths of pipe will be necessary to insert and steer to the beginning point and help you choose an entry point.
Given the above information, you can calculate the number of rods required to reach your beginning point at the appropriate depth. Toro recommends that you start the entry point the same distance back from your beginning-at-depth point as the length of pipes you will need to reach that point. This will ensure that you have enough extra space so you will not need to over-steer and damage the pipes.
• Insert the first 3 m (10 ft) of drill bit/pipe into the ground The following example illustrates the process given an installation using the machine at an 18% pitch on level ground: with no steering. The end of the drill bit will be 53 cm (21 inches) deep (Figure 56). Figure 56 1. 18% pitch 3. 96 cm (38 inches) 5. 119 cm (47 inches) 2. 53 cm (21 inches) 4. 114 cm (45 inches) 6. 10.

Understanding and Using the Handheld Transmitter Indicator Lights Meaning Indicator Light State The individual holding the transmitter can push the Lock Drill (Off) button to stop the drill rotation and thrust.
Preparing the Job Site and the Machine Important: Ensure that you install the batteries in the correct polarity orientation or you could damage the transmitter. Before drilling, prepare the job site and the machine as follows: • Mark and prepare the bore path Marking and Preparing the Bore Path (page 58). • Test the Zap-Alert system; refer to Testing the Zap-alert System (page 59). • Load the drill pipes into the pipe holder if needed; refer to Loading Drill Pipes into the Pipe Holder (page 61).
Testing the Zap-alert System The Zap-Alert system is an electric strike sensing device on the machine that triggers a strobe light and audible alarm in the event that the drill bit, reamer, or stake breaks into an energized power line. In the event of an electric strike, the machine will become energized, setting off the alarm. DANGER If the Zap-alert system activates while drilling, the machine, except for the operator platform, will become energized.
7. Disconnect the alligator clips from the grounding stud and the machine. 8. Store the grounding stake in the holder on the operator platform as shown in Figure 63. 1 g021838 Figure 63 1. Grounding stake If either the audible alarm or the strobe light fail to trigger when you pressed the test button, have them repaired before drilling with the machine. Mounting a Fire Extinguisher Mount your fire extinguisher below the operator seat (Figure 64).
Loading Drill Pipes into the Pipe Holder Before using the machine, fill the pipe holder with up to 40 drill pipes. Figure 65 1. Pipe 2. Male end 3. Clevis pins Adding Fuel 1. Remove the clevis pins from the pipe holder (Figure 65). Service Interval: Before each use or daily—Check the fuel level. 2. Insert the pipes from the top with the male threaded pipe ends toward the front of the machine (Figure 65). Use only clean, fresh diesel fuel or biodiesel fuels with ultra low (<15 ppm) sulfur content.
• If this is not possible, then refuel such equipment on cold flow characteristics which will ease starting and reduce fuel filter plugging. a truck or trailer from a portable container rather than from a fuel dispenser nozzle. Using summer grade fuel above -7° C (20° F) will contribute toward longer fuel pump life and increased power compared to winter grade fuel.
Checking the Engine-oil Level Note: Be sure to keep this safe distance whenever moving the machine. Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking the Engine-oil Level (page 88). 6. Press and hold the operator presence button on the drive pendant. Checking the Cooling System 7. Use the speed switch on the pendant to increase or decrease the engine speed as desired. 8. Set the desired travel speed using the speed switch.
11. Remove the block from the trailer tires, and stow them with the machine for use when unloading it. 12. After driving a few miles, pull over and check to ensure that all chains are still tight and that the machine has not moved. Note: To unload the machine, reverse the above procedure. Setting up the Machine for Drilling 1.
Figure 70 1. Pedestrian safety bar (lowered position shown) Figure 72 1. Front pin 5. Push down on the rear platform latch securing the operator platform, and swing it out to the desired position, ensuring that it locks in place (Figure 71). 2. Rear pin 7. Load the first pipe and install the sonde and the drill head; refer to Starting the First Pipe (page 68). Note: The operator platform has 4 positions: travel (swung all the way into the machine), full-out, and 2 intermediate positions. 8.
Connecting to a Drilling-fluid Source When drilling and reaming, you pump a mixture of bentonite clay, water, and sometimes other ingredients, collectively called drilling fluid or “mud”, through the pipe and into the bore. This drilling fluid, or “mud”, does the following for your bore: • Lubricates the drill head • Loosens the soil into which the drill is cutting • Penetrates and binds loose soil to keep it from collapsing on the bore pipe.
Deploying the Zap-alert System 2. Insert the hose from the mixing system over the pump inlet, and secure it with the cam-lock levers. The Zap-alert system is an electric strike-sensing device on the machine that triggers a strobe light and an audible alarm whenever the drill bit, reamer, or stake breaks into an energized power line. In the event of an electric strike, the machine will become energized, setting off the alarm.
4. Lower the elevators to load a pipe into the cam. 1 5. Rotate the cam with the pipe facing toward the operator until the cam stops. 6. Rotate the pipe-gripper cam forward until the pipe is in the grippers. 7. Grip the pipe with the pipe grippers. 8. Continue to rotate the pipe-gripper cam toward the operator, until the pipe is aligned with the drill spindle. 9. Rotate the drill spindle clockwise, and move the carriage slowly forward to insert the spindle into the female end of the pipe (Figure 80).
Setting up the Drill Head and the Tracking System The drill head consists of 2 parts, the drill bit and the sonde housing (Figure 81). Figure 81 1. Sonde housing Figure 82 2. Drill bit Drill bits vary in size and type to meet the various soil conditions that you may need to drill through. Some of the possibilities are as follows: 1. Sonde housing 4. Cover holes 2. Bolts 3. Drill bit 5. Cover 3. Insert the sonde beacon with the forward end toward the drill bit into the sonde housing (Figure 83).
Installing the Drill Head 5. Using the lower wrench (stationary wrench), clamp the lead bar, and tighten the drill spindle to full-seat threads. 1. Using the exit-side-lockout transmitter, activate the exit-side lockout to disable the thrust and rotation of the carriage. 6. Double check the drill head and bit to ensure that the fluid ports are clean and free from obstructions. 7.
Adding Drill Pipes Steering the Drill Head 1. Align the pipe joint in the wrench assembly. The drill bit is shaped like a wedge, angled from one side of the bit to the other. When you push the bit through the soil without rotating it, it will veer toward the direction the wedge is pointing. When you rotate the pipe and drill head, it bores through the soil in a straight path. 2. Close the lower wrench (stationary wrench) onto the first pipe.
Backreaming and Pullback Note: This may loosen the obstruction and allow you to push past it. After drilling the initial bore, you attach a reamer to the pipe, which is then connected to a the product that you are installing. The reamer is designed to widen the bore, pack the walls, and lubricate the passage of the product into the bore. 2.
Removing Drill Pipes 12. Rotate the drill spindle counterclockwise, moving rearward slowly until the pipes are separated. 1. Using the exit-side-lockout transmitter, enable the exit side lockout. 13. Move the drill carriage back until the male, pipe threads just clear the female end of the lower pipe, then close the upper wrench (makeup/breakout wrench) onto the pipe end, but not on the threads. 2. Install a drill-pipe wiper around the pipe and into the retaining bracket on the front of the machine.
Removing the Last Pipe and the Reamer Using the TJC Applicator Important: Do not pull the drill head into the pipe guide, or you may damage the machine or the drill head. Adjusting the Applicator Nozzle 1. Using the exit-side-lockout transmitter, enable the exit side lockout. You can adjust the applicator nozzle to spray thread-joint compound (TJC) either in a fan-shaped spray or as a stream. 2.
Adjusting the TJC-spray Volume Filling the TJC Applicator 1. Loosen the jam nut on the adjustment bolt located on top of the TJC-applicator piston (Figure 88). 1. Stop the machine and stop the engine. 2. Open the stake-down-guard door. 3. Loosen the wing nuts securing the cover straps to the machine (Figure 89). Figure 88 1. Adjustment bolt 3. TJC-applicator piston 2. Jam nut Figure 89 2. Adjust the bolts as follows: • To increase the applied volume of compound, thread the bolt out (up). 1.
Moving a Disabled Machine Replacing the Pipe Holder 1. Ensure that the 2 upper pins and the 2 lower pins are installed to secure the pipe inside the pipe holder (Figure 91). Whenever the machine is stopped and the engine is not running, the hydrostatic brakes automatically engage. Do not attempt to tow the machine if it cannot move under its own power. If possible, repair the machine at the site.
