Operation 4. Drill the bore. You drill the bore in 3 stages: Note: Determine the left and right sides of the machine from the normal operating position. 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).
Gathering Site Information 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.
– Electrical power lines – 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. DANGER Drilling into an electric power line will cause the machine to become electrified and may electrocute you or any bystanders. ◊ Keep bystanders and spectators away from the job site, including the complete bore path.
Planning the Bore Path Before setting up the job site, you need to plan the bore path, including the following: Figure 24 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 25 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 33 m (108.2 ft). 1 2 • Entry pitch g021767 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 29). Figure 29 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.
Testing the Zap-Alert System Preparing the Job Site and the Machine 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.
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 31. 1 g021838 Figure 31 Figure 30 1. Test button 2. Zap-alert tester 5. Reset button 6. Alligator clips 3. Zap-alert system 7. Machine grounding point 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. 4.
Loading Drill Pipes into the Pipe Holder Before using the machine, fill the pipe holder with up to 40 drill pipes. Figure 33 1. Pipe 2. Male end 3. Clevis pins Adding Fuel 1. Remove the clevis pins from the pipe holder (Figure 33). 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 33). Use only clean, fresh diesel fuel or biodiesel fuels with ultra low (<15 ppm) sulfur content.
Using summer grade fuel above -7° C (20° F) will contribute toward longer fuel pump life and increased power compared to winter grade fuel. DANGER In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property. Important: Do not use kerosene or gasoline instead of diesel fuel. Failure to observe this caution will damage the engine. • Fill the fuel tank outdoors, in an open area, when the engine is cold.
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 72). 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.
DANGER If the Zap-alert system activates while drilling, the machine, except for the operator platform, will become energized. If you step off the operator platform or if someone touches the machine or wet ground near the machine or in the bore, you or the one who touched the machine could be electrocuted, causing serious injury or death. • Test the Zap-alert system before drilling. Figure 38 • Deploy the grounding stake before drilling. Ensure that the stake is fully inserted into moist soil. 1.
Note: If the ground is soft, place timber below the stabilizers, and lower the stabilizers. 3. If the ground is dry where you put the stake, soak the ground with water before using the machine to ensure good electrical contact. Lowering the Stakes 1. Move the operator station to the desired angle, switch the DRILL/DRIVE switch to the DRILL position, and raise the pipe elevators, so that the pipe is resting on the elevators; refer to Starting the First Pipe (page 51).
• Loosens the soil into which the drill is cutting • Penetrates and binds loose soil to keep it from collapsing 1. Remove the pump-inlet cap (Figure 46). on the bore pipe. Important: Do not operate the drilling-fluid pump without a pressurized supply of drilling fluid, or damage to the pumping system will result. The specific mixture you need will vary depending on your soil type and the operation that you are performing. Refer to your mixing system Operator’s Manual for details.
11. Continue to rotate the drill spindle clockwise, until the male pipe thread is fully seated into the sonde housing or lead bar. 12. Release and retract the pipe-gripper cam to the HOME position. Important: Ensure that you fully retract the pipe gripper and rotate it all the way out or the carriage may collide with the gripper, damaging the machine. 13. Raise the pipe elevator. 14. Retract the cam to the HOME position (past the fourth row of pipes). Figure 47 1. Drill spindle 2.
Setting up the Drill Head and the Tracking System The drill head consists of 2 parts, the drill bit and the sonde housing (Figure 49). Figure 49 1. Sonde housing Figure 50 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 51).
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.
Steering the Drill Head 5. Spray the spindle with thread joint compound, then return the drive carriage to the upper end of the frame. 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. 6. Rotate the pipe-gripper cam to the closest row of pipes in the pipe holder. 7.
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.
5. Remove and store the last pipe; refer to Removing Drill Pipes (page 57). Using the TJC Applicator 6. Leave the lead bar clamped in the lower wrench (stationary wrench), but do not connect the drill spindle to the lead bar. Adjusting the Applicator Nozzle You can adjust the applicator nozzle to spray thread-joint compound (TJC) either in a fan-shaped spray or as a stream. 7. Remove the reamer from the end of the lead bar as directed by the reamer manufacturer.
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 56). 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 57). Figure 56 1. Adjustment bolt 3.
