Breaking Rod Joint
If for any reason a drill rod joint cannot be broken
at the vise, repair the vise. Never put a pipe
wrench or tong on the drill string and use drilling
machine torque to break the joint. Never use a pipe
wrench or tongs and apply force by using a
backhoe. The wrench could slip off the drill string
and strike you.
If a problem arises in drilling out or pullback which
requires making or breaking a joint between the
tool and the machine, it is very important not to
use a pipe wrench, but to use only a compact
remote breakout system.
A compact remote breakout system is required
whenever you loosen a joint away from the
machine. Serious injury or death can occur if drill string rotation starts and you are struck by the wrench.
