Cruise Control
Make Up and Break Out Joints Correctly
Assisted Makeup protects threads by automatically matching carriage movement speed to rotation during
makeup and breakout. Operator controls rotation speed while the unit controls carriage travel.
• To connect pipes together and fully tighten joint, slowly rotate pipe as threads come in contact.
Carriage will move forward automatically as threads engage. Continue rotation until spindle stops
turning and full pressure is developed. Improperly tightened joints will damage the shoulder faces
and threads, and will cause joints to leak or break while drilling or backreaming.
• To disconnect pipes, slowly rotate spindle counterclockwise. Carriage will move back automatically
until threads fully separate.
Do not Overwork the Pipe
Never exceed the bend radius for your pipe. See “Plan Bore Path” on page 87. Do not oversteer.
Cruise Control
During the bore, you can set the desired thrust, pullback, and rotation speeds to match ground conditions.
Cruise control enables the unit to maintain these settings hands-free. You can engage, disengage,
override, and resume these settings at any time.
Engage
NOTICE: Bending pipe more sharply than recommended will damage pipe and cause failure.
IMPORTANT: In order for cruise control to function, front wrench must be open and shuttles must be
under pipe box.
