10 Bleeding the Air from the Tilt and Trim Cylinders and the Hydraulic Motor No Parts Required Figure 59 1. Button 5 Bleeding the Air from the Tilt and Trim Cylinders 5. Ensure that the vibratory plow is level. DANGER 6. Perform the following to bleed the tilt cylinder: Pressing the elevation float switch or the swing float while you are bleeding the hydraulic system will cause the attachment to move uncontrollably and may result in personal injury or death, or damage the attachment.
Operation Using the Transport Lock Unlocking the Transport Lock 1. Start the traction unit and set the parking brake. 2. Press the tilt switch up until the shaker box is fully tilted up and forward. Important: Moving the vibratory plow to the fully-raised position without first fully tilting the shaker forward and up before raising the plow will damage the tilt cylinder. Figure 61 3. Slowly raise the vibratory plow to its full height; refer to Using the Backfill Blade/Vibratory Plow Joystick (page 30).
3. Slowly raise the vibratory plow to full height; refer to Using the Backfill Blade/Vibratory Plow Joystick (page 30). Note: When the vibratory plow is in the full up position, the transport lock will automatically engage the cam on the upper strut (Figure 63). Important: Before moving the traction unit or performing maintenance, ensure that the plow is in the full up position and cam on the upper strut fully engages the hook of the transport lock.
Using the Backfill Blade/Vibratory Plow Joystick Note: Set the backfill blade/vibratory plow command button (button 5) to the vibratory plow function to change the attachment joystick function; refer to Using the Command Center (page 29). Backfill Blade/Vibratory Plow Joystick • Move the backfill blade/vibratory plow joystick toward you to raise the elevation of the vibratory plow (Figure 65 and Figure 66).
Figure 71 Using the Elevation-float Switch Figure 69 1. Vibratory plow/trencher motor joystick Note: The vibratory plow has 2 operation modes that you can use the elevation-float switch to control: Float position—the plow will follow the contour of the ground when the elevation-float switch to the float position. Off (fixed-position)—the plow will stop moving or floating when you move the elevation-float switch to the off position. 2.
7. Align the lower hole in the plow blade with the mounting hole in the stabilizer. 8. Install the blade-mounting pin through the mounting hole in the stabilizer and through the lower hole in the plow blade (Figure 74). Figure 73 Note: Ensure that the head of the pin is flush with the surface of the stabilizer. Installing and Removing the Vibratory Plow Blade 9. Install the safety pins into the holes in the blademounting pins, and close the bales over the mounting pins (Figure 74).
WARNING Vibrations from the plow can cause the soil of an overhang or high bank to fall and cause injury or death. Keep people and animals away from nearby overhangs and high banks while you are operating the vibratory plow. Setting the Shoe Position on the Stabilizer You can set the wear-plate shoes for the stabilizer to 2 positions depending on operating conditions, blade selection, and your preference. To change the position of the stabilizer shoes, perform the following steps: Figure 75 1.
2. Insert the cable that you are installing at the work site into the chute; refer to Installing Cable into the Cable Chute (page 32). 6. Repeat steps 1 through 5 for the other wear plate and stabilizer shoe. Positioning the Seat for Plowing 3. Move the backfill blade/vibratory plow joystick toward you to lower the plow blade to the surface of the soil. Fasten the seat belt and rotate the seat clockwise. Note: Anchor the end of the cable as necessary.
Figure 80 1. Traction unit—forward Figure 79 1. Down-shift button (utility-traction joystick) 2. Utility-traction joystick 3. Icon—gear-shift pattern 6. Once the blade enters the ground, begin the blade-vibration function by lifting up on the lock ring that is at the bottom of vibratory plow/trencher motor joystick moving the joystick toward you (Figure 81). 2. Up-shift button (utility-traction joystick) C. 3.
Note: This lets the obstacle to move around side of the plow or allows the plow blade to move around the obstacle Plowing Cable from a Building Wall 1. Dig a hole next to the wall of the building where the cable will enter the building (Figure 84). Figure 82 Figure 83 1. Float (swing-float switch) 2. Off (swing-float switch) Figure 84 Important: You will damage the cable and the chute if you force the blade into the ground too fast.
1. Ensure that the stabilizer shoes are set to the wide position; refer to Setting the Shoe Position on the Stabilizer (page 33). plow/trencher motor joystick toward you; refer to Using the Vibratory Plow/Trencher Motor Joystick (page 30). 2. Dig a service hole down where the cable will join the service connection to the plowing depth of the cable run (Figure 85) and no wider than 0.6 m (24 inches). Important: Do not start the blade-vibration function of the plow until the blade has entered the ground.
6. Move the traction unit to the position that aligns the plow blade with the next direction for the cable run and alongside the service hole (Figure 87). 7. Carefully lower the blade into the service hole. 8. Install the cable into the chute and install the gate to the chute; refer to Installing Cable into the Cable Chute (page 32). 9. While feeding the cable into the chute, move the traction unit forward until the blade enters the soil on the side of the service hole (Figure 87). 10.
Transporting the Traction Unit with a Vibratory Plow Transporting the Traction Unit with a Vibratory Plow 1. Remove the plow blade; refer to Removing the Plow Blade (page 32). 2. Move the vibratory plow onto the transport position; refer to Locking the Transport Lock (page 28). Figure 90 1. Utility-traction joystick 3. Drive the traction unit onto the transport vehicle. 3.
Operating Tips the centered position, the side draft of the blade will cause the tires of the traction unit to slip more easily. • Operate the plow with the elevation-float switch in • When you plow with the shaker and blade offset from the the Float position; otherwise, excess vibration will be transmitted to the traction unit and damage it. Therefore, you must use a blade with the proper plowing depth for the job being performed.
Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 5 hours • Torque the fasteners on the shaker box. Before each use or daily • Grease the fittings. • Torque the fasteners on the shaker box. Every 40 hours Note: Looking for an Electrical Schematic or Hydraulic Schematic for your machine? Download a free copy of the schematic by visiting www.Toro.com and searching for your machine from the Manuals link on the home page.
Torquing the Fasteners on the Shaker Box Service Interval: After the first 5 hours Every 40 hours Torque the bolts and nuts on the shaker box to 183 to 203 N-m (135 to 150 ft-lb) in the pattern shown in Figure 95. Figure 94 1.
Storage 1. Before storing the traction unit, brush off the dirt from the attachment. Note: Refer to the traction unit Operator’s Manual for storing the traction unit. 2. Check the condition of the hoses, the stabilizer shoes, the plow blade, and the cable chute. Replace any worn or damaged parts. 3. Check and tighten all bolts, nuts, and screws. Repair or replace any part that is damaged or worn. 4. Ensure that all hydraulic couplers are connected together to prevent contaminating the hydraulic system. 5.
Troubleshooting Problem The plow does not vibrate. The blade does not plow fast enough. Possible Cause Corrective Action 1. A hydraulic fitting is not completely connected. 1. Check and tighten all fittings. 2. A hydraulic fitting is damaged. 3. There is an obstruction in a hydraulic hose. 4. The drive-control cable is disconnected or has failed. 5. The hydraulic motor has failed. 6. The hydraulic pump has failed. 2. Replace the damaged fitting. 3. Find and remove the obstruction. 4.
