Route hose C (36 inches) from the straight fitting (In Port) on the hydra-borer control valve (Figure 14) to the hose connector on hose D (Figure 21). Use this procedure if you have a machine that has a trencher attached. If you have a machine that does not have a trencher attached, go to Installing the Hoses on a Machine without the Trencher Attachment Installed (page 9).

Installing the Hoses on a Machine with the Trencher Attachment Installed Use this procedure if you have a machine that has a trencher attached. If you have a machine that does not have a trencher attached, go to Installing the Hoses on a Machine without the Trencher Attachment Installed (page 11). 1. Remove the short hose coming from the trencher valve that is connected to the long hose leading to the plow-cylinder valve (Figure 25). The short hose is not needed for this installation.
Boring the Hole 6 Important: Boring is a two person operation. Do not attempt to perform this operation by yourself. 1. Position the machine with the drive head at the beginning of the trench and lower it to the appropriate depth. Testing the Installation No Parts Required 2. Stop the engine and wait for all moving parts to stop. 3. Connect a rod and boring bit onto the drive head. Procedure 4. Connect the rod guide tool to the rod just behind the boring bit (Figure 29).
6. When a rod coupling is about 15 cm (6 inches) into the entrance trench or when the reamer completely enters the trench with about 15 cm (6 inches) of the cable or piping, stop the machine, pull the control lever into neutral, and stop the engine. rate. Do not push or pull the bit through the soil when the drive head is not turning. 13.
Storage 1. Before long term storage, wash the attachment with mild detergent and water to remove dirt and grime. 2. Check the condition of the hydraulic hoses. Replace any damaged hoses. 3. Ensure that all hydraulic couplers are connected together to prevent contamination of the hydraulic system. 4. Check and tighten all bolts, nuts, and screws. Repair or replace any damaged or worn part. 5. Paint all scratched or bare metal surfaces. Paint is available from your Authorized Service Dealer. 6.
Troubleshooting Problem The bore drive head does not rotate. Possible Cause Corrective Action 1. The hydraulic coupler is not completely connected. 1. Check and tighten all couplers. 2. A hydraulic coupler is damaged. 2. Check the couplers and replace any that are damaged. 3. Find and remove the obstruction. 3. There is an obstruction in a hydraulic hose. 4. A hydraulic hose is kinked. 5. The auxiliary valve on the machine is not opening. 6. A hydraulic motor is damaged or worn. 16 4.
