Digging the Trenches

    Graphic
    g008476
  1. Mark planned bore path and all located utility lines with flags or paint.
  2. Dig both trenches at least 10 cm (4 inches) wide and 45.72 cm (18 inches) deep.
  3. Dig the approach trench at least 216.36 cm (7 ft) long.
    Note: The approach trench should be perpendicular to the sidewalk or driveway.
  4. Dig the target trench to be 91.44 cm (3 ft) to 182.88 cm (6 ft) long.
    Note: The target trench should be centered across from the approach trench.

Boring the Hole

Danger
Contact with the rotating shaft will cause death or serious injury. Stay at least 2 m (6 ft).
To help avoid injury
  • Keep everyone at least 3 m (10 ft) away from the drill string and machine unless the rod guide tool is need.
  • Never force the drilling process. The drilling bit will drift off course and the rod sections may bow or break. Proceed slowly and carefully.
  • Never drill with a bent rod section.
 
Warning
Underground utilities contact can cause death or serious injury. Locate and verify underground utilities before digging or drilling.
To help avoid injury: Only operate the drilling attachment if the bore path is more than 3 m (10 ft) from any underground hazard.
 
Important
Boring is a 2 person operation. Do not attempt to perform this operation by yourself.
 
  1. With the person guiding the boring bit positioned to the right of the trench, start the machine, set it to low throttle, and push the hydra-borer-control lever forward to start the forward rotation of the drill bit.
  2. Slowly move the machine forward, while the person with the rod guide tool guides the boring bit into the soil.
  3. Once the entire drill bit is in the soil, return all controls to neutral.
  4. Turn off the machine and wait for all moving parts to stop.
  5. Carefully monitor the drill string to ensure the rod is not bowing or whipping in the trench.
  6. Remove the rod guide tool.
  7. Start the machine and push the control lever forward to start the boring bit.
  8. Slowly move the machine forward as the boring bit digs into the soil.
    Important  
    Do not drive too fast, forcing the bit into the soil. Allow the bit to progress at its own rate. Do not push or pull the bit through the soil when the drive head is not turning.
     
  9. When about 15 cm (6 inches) of rod are left showing in the entrance trench or when the boring bit completely enters and bores into the far side of the exit trench, stop the machine, return the control lever into neutral, and stop the engine.
  10. If the boring bit has not yet entered the target trench, complete the following:
    1. Detach the rod from the drive head.
    2. Start the engine and back up to the end of the approach trench.
    3. Stop engine and wait for all moving parts to stop.
    4. Connect another rod and repeat steps 7 through 10.

Backreaming the Hole

Sometimes it is necessary to drill a pilot hole first, then enlarge the hole to accommodate larger product. As a general rule, the final hole should be 1.5 times larger than the diameter of the product being installed. The number of passes needed depends on the soil conditions.
    Graphic
    g008478
  1. With a shovel, carefully dig around the boring bit, in the target trench , clearing it of soil until it can be removed.
  2. Turn off the machine.
  3. Remove the boring bit and attach the backreamer .
  4. Attach the product being installed to the swivel on the end of the backreamer.
    Note: Pull product through the bore after drilling or at final pass of backreaming.
  5. Start the machine and push the control lever forward to start the reamer.
  6. Slowly move the machine rearward as the reamer digs into the soil.
    Important  
    Do not drive too fast, forcing the backreamer into the soil. Allow the reamer to progress at its own rate. Do not push or pull the backreamer through the soil when the drive head is not turning.
     
  7. When the rod coupling is about 15 cm (6 inches) into the approach trench or when the backreamer completely enters the approach trench with about 15 cm (6 inches) of the cable or piping, stop the machine, pull the control lever into neutral, and turn off the machine.
    Note: Do not have more than 9 m (30 ft) of exposed rod outside the bore. Remove the rods as necessary.
