30-12 Overview D7x11 Series II Navigator Directional Drill
IMPORTANT: Never approach drill string or attempt to apply a tool to drill string until after Remote Lockout is
confirmed by the 9 beeps and red lockout light, and by radio communication between the remote transmitter
operator and the machine operator.
Step 5: If lockout is unsuccessful using Remote Lockout system, follow “Lockout Procedure - Without Remote
Lockout System,” page 30-13.
NOTE: Anytime a Remote Lockout command is not successful, ensure machine is running, is in Drill mode
(operator seated at controls), and that transmitter is within range. If problem still exists, contact your Vermeer
dealer to determine the source of the problem.
NOTE: The Remote Lockout system is not operational when the machine is in Transport mode.
Step 6: Complete whatever work is required to change tools or repair and replace drill rod or tooling only after
the machine is locked out.
Resuming Operation after Remote Lockout
Step 1: Verify that drill rod and cutting tools are ready for operation.
Step 2: Warn everyone who may be exposed to drill string or cutting tools that operation
will resume.
Step 3: Confirm everyone has evacuated the exit pit and is away from drill string and
cutting tools, and that no wrenches or breakout tools are attached to drill string
or cutting tools.
Step 4: Press Run Button (2) and hold for 2 seconds to return control of drilling
functions to the machine operator.
NOTE: If RUN command is not successful and the Remote Lockout transmitter is within
range, Remote Lockout system must be repaired before the machine can resume drilling.
Step 5: Communicate by radio with machine operator that normal operation can resume.
