14 1/2" Closed Mouth Trailer-Mounted Bucking Unit Setup & Operation 1. INITIAL START UP & BREAK-IN PROCEDURE ALTHOUGH YOUR NEW EQUIPMENT HAS BEEN TESTED AND INSPECTED AT THE FARR FACTORY PRIOR TO SHIPPING, WE ADVISE THOROUGH TESTING OF YOUR NEW TONG AFTER YOU TAKEN POSESSION IN ORDER TO ELIMINATE THE POSSIBILITY OF SHIPPING DAMAGE.
Setup & Operation BEST BY FARR TM 14 1/2" Closed Mouth Trailer-Mounted Bucking Unit 2. VALVE OPERATION 4-way proportional valves control operation of hydraulic devices on the bucking unit such as hydraulic motors and lift cylinders. When any one valve is “centered” or in the detent position, there is no hydraulic output from the valve. When the valve is pushed forward there is an effect, and when the valve is pulled back, there is an opposite effect.
Setup & Operation TONG SHIFT This is a two-way direct acting valve, without proportional control. When the valve is in the middle (detent) position, the tong is in “neutral”, or not rotating. Pulling the valve handle backward, or toward the operator, will cause the tong to begin rotating in low gear. Pushing the valve handle forward through the neutral position will cause the tong to shift to a higher gear, and increase the rotational speed.
Setup & Operation 14 1/2" Closed Mouth Trailer-Mounted Bucking Unit BEST BY FARR TM 3. GENERAL COMMENTS a) b) Position rotary gear in contact with idler gears prior to breaking out joints or collars where high torques are required. When making-up integral (shouldered) joints, it is essential to make up the last turn of the threads in low gear. This reduces the tendency of an instant stop or a sudden increase in torque, which induces extremely high stresses on the gear train.
Setup & Operation The bottom plates on all four hydraulic jacks need to be flat and secure on a stable surface before running pipe. 3.

Torque Gauge Service Information TROUBLESHOOTING Under normal operating conditions, and with proper maintenance, the torque gauge and load cell system are designed to give lasting trouble-free performance. Faulty indication on the gauge will very often define a fault within the gauge. * IF TROUBLESHOOTING REVEALS THAT THERE IS INSUFFICIENT FLUID IN THE SYSTEM, BEFORE RECHARGING, CHECK THAT ALL SYSTEM COMPONENTS ARE FREE FROM DAMAGE. THIS WILL ENSURE THAT FLUID LOSS WILL NOT CONTINUE AFTER RELOADING. 1.
