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 - Without Remote Lockout System,”
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.
