Short-String Method of Adding Drill Rod for Pre-Reaming
Step 1: Pre-assemble as many rods as practical at the exit location. These will be attached later to reamer
swivel. Before assembling rod joints, clean and lubricate threads.
Step 2: Join rods using pipe wrenches, and apply at least 400 ft-lb (540 Nm) torque to tighten snugly. It is not
necessary to tighten joints to a higher torque.
Step 3: Attach rod recycler adapter to the first drill rod and tighten snugly.
Step 4: Use correct lockout procedures.
• “Lockout Procedure - With Remote Lockout,” page 30-14
• “Lockout Procedure - Without Remote Lockout System,” page 30-17
Step 5: Attach rod recycler adapter to swivel.
WARNING: Never attach a pipe wrench or tool and apply force from a
machine such as a backhoe to tighten or break a connection. If the
wrench slips off the bucket, the wrench could rotate or be thrown and
strike you. Death or serious injury may result.
