Remote Lockout Overview
The Remote Lockout system is not intended to replace good verbal radio communication. Radio communication
is essential to the Remote Lockout system process. Refer to “Radio Communication Requirements,” page 40-3.
REMOTE LOCKOUT SYSTEM INTENDED USE
The Remote Lockout system is a communication and control tool that allows a worker anywhere along the bore
path or at the exit site, to directly lock out drill rod rotation, thrust, and fluid flow. Lights, sound, and vibration
indicate various modes so the machine operator and remote user know that the Remote Lockout system is
operating correctly and whether drilling functions are locked out.
When in Transport mode, the machine will not respond to Remote Lockout system commands until machine is
returned to Drill mode.
Although the Remote Lockout system can stop thrust, rotation, and fluid flow while drilling, the purpose of the
system is to prevent these functions from being started in the first place.
