McCoy Drilling & Completions recommends that the following pre-operating tests be performed after receipt from the factory or after
extended storage, prior to releasing the tong to operations:
• Perform a complete inspection of all fasteners to ensure none have loosened during transport.
• Connect the tong to the power unit, and apply full hydraulic pressure. Inspect and correct any leaks.
• Operate the tong at full speed and in high gear for a duration of one-half hour. Hot bearing caps may indicate impending bearing
failure.
• Switch to low gear and operate for an additional one-half hour at full speed.
• Inspect all components and hydraulic fittings for possible defects following completion of the tests. All Farr® Tongs have been
thoroughly tested at the factory prior to shipping, but shipping damage must be identified before running the tong in an operational
environment.
• Carefully inspect the safety door components, and test to ensure that the safety device on each door is operating correctly before
releasing the tong to the operating environment.
YOUR EQUIPMENT HAS BEEN THOROUGHLY TESTED AND INSPECTED AT THE FACTORY.
HOWEVER, WE ADVISE INSPECTION AND TESTING OF YOUR NEW TONG AFTER TAKING
POSSESSION IN ORDER TO ELIMINATE THE POSSIBILITY OF SHIPPING DAMAGE.
