WARNING
ANY REPLACEMENT FASTENER (BOLTS, NUTS, CAP SCREWS, MACHINE SCREWS, ETC.) USED DURING
MAINTENANCE OR OVERHAUL MUST BE GRADE 8 OR EQUIVALENT UNLESS OTHERWISE SPECIFIED.
WHEN RE-ASSEMBLING LOAD-BEARING DEVICES (CHAIN SLINGS, RIGID SLINGS, BACKUP LEGS, ETC.)
NOTE THAT THE ASSOCIATED FASTENERS MUST BE TIGHTENED TO THE CORRECT TORQUE SPECIFIED
FOR THAT SIZE OF FASTENER (SEE SECTION 3 - OVERHAUL). ANY THREADED FASTENER IN A LOAD-
BEARING DEVICE MUST BE SECURED WITH RED OR BLUE LOCTITE™.
A “LOAD-BEARING DEVICE” IS A CHAIN SLING, RIGID SLING, SPREADER BAR ASSEMBLY, FRAME, OR
ANY OTHER DEVICE THAT BEARS THE PARTIAL OR TOTAL WEIGHT OF THE EQUIPMENT FOR WHICH THIS
MANUAL HAS BEEN PRODUCED
THE LOAD-BEARING DEVICE SUPPLIED BY MCCOY GLOBAL IS DESIGNED TO SUPPORT THE EQUIPMENT
DESCRIBED IN THIS MANUAL. MCCOY GLOBAL WILL NOT GUARANTEE THE ABILITY OF THE LOAD-BEAR-
ING DEVICE TO SUPPORT ANY OTHER PART, ASSEMBLY OR COMBINATION OF PARTS AND ASSEMBLIES.
MCCOY GLOBAL WILL NOT GUARANTEE THE ABILITY OF THE LOAD-BEARING DEVICE TO LIFT OR SUP-
PORT THE EQUIPMENT DESCRIBED IN THIS MANUAL IF THERE ARE ANY MODIFICATIONS TO THE LOAD-
BEARING DEVICE, OR ANY ADDITIONS TO THE EQUIPMENT DESCRIBED IN THIS MANUAL THAT ADD

IDENTIFICATION OF WARNINGSAND OTHER NOMENCLATURE OF
IMPORTANCE USED IN THIS TECHNICAL MANUAL
McCoy Global uses three indicators to describe items of three degrees of importance.
A HAZARD to operators or equipment is represented by an exclamation point within a red triangle. identifies items of the highest
importance. Failure to heed information identified by a HAZARD symbol may result in bodily injury, death, catastrophic equip-
ment damage, or any combination of these. A HAZARD may also indicate the potential for dangerous environmental contamina-
tion.
The information presented in this document will provide setup, operating, and maintenance instructions for your
KT14-75K tong. Due to the wide variety of operating conditions, these instructions must be considered guidelines
rather than absolute operating procedures. It is the responsibility of the user to use these guidelines together with
an experienced manager to develop operating procedures that conform to all policies set forth by the operating
authority (ies).
A WARNING is represented by an exclamation point within an orange triangle, and contains information that will alert personnel to a potential
safety hazard that is not life-threatening.AWARNING may also serve to alert the user to information critical to the correct assembly or operation
of the equipment in use.
This identies a HAZARD to operators or equipment
This identies a WARNING to users
A CAUTION is represented by an exclamation point within a yellow triangle and highlights information that may aid the user dur-
ing assembly or operation of your equipment. CAUTIONs are also used to ensure common errors are not made during assembly
or operation of your equipment.
This identies a CAUTION to users
Observance of the following is the full responsibility of the user:
• all descriptions, information and instructions set out in this manual
• any regulation or requirement issued by an authority or agency which may influence operation, safety
or integrity of the equipment that overrules the content of this document.

Torque Table
Please note that these are ideal values. Actual achieved
torque is highly dependant upon tong efciency and
nal position of rotary gear when full torque load is
reached. Maximum torque is only available in low gear
and full motor displacement.

RECOMMENDED LUBRICANT SPECIFICATIONS
Hydraulic Fluid
McCoy Global recommends using high-quality hydraulic fluid containing rust & oxidation inhibitors and foam suppressant that
meets the following requirements. Operating this equipment using hydraulic fluid that does not meet these requirements greatly
accelerates equipment damage due to (but not limited to) premature component wear, premature seal failure, cavitation, and
fluid starvation.
!CAUTION
OPERATING THIS EQUIPMENT USING HYDRAULIC FLUID THAT DOES NOT MEET THE LISTED REQUIREMENTS
GREATLY ACCELERATES EQUIPMENT DAMAGE.
Hydraulic Fluid Standards
Characteristic Requirement
Maximum viscosity at cold startup <1000 cSt (<4600 SUS)
Operating viscosity range 100 to 16 cSt (170 to 80 SUS)
Minimum viscosity (intermittent periods only) 10 cSt (60 SUS)
Hydraulic uid operating temperature range 86 - 140°F (30 - 60°C) - measured in main reservoir
Maximum uid temperature 180°F (82°C)
Fluid cleanliness Filtered to ISO 4406:1999 (22/18/13)
Hydraulic fluid should be chosen with due regard to expected climactic conditions and equipment load. Note that this equipment
may have been tested using hydraulic fluid that does not meet operational requirements beyond those specified in the above
table. Therefore, McCoy recommends purging and flushing the equipment’s hydraulic system before connecting to a hydraulic
supply.
NOTICE
MCCOY GLOBAL RECOMMENDS PURGING AND FLUSHING THE EQUIPMENT’S HYDRAULIC SYSTEM BEFORE
CONNECTING TO A HYDRAULIC SUPPLY.
Gear Fluid
McCoy Global recommends using a high-quality universal gear uid in gearbox and torque hub assemblies. If required, the gear
uid should meet VG150/VG220 or AGMA 4EP/5EP specications. However, in more extreme operating conditions it may be
necessary to ll the gearboxes on the equipment with gear uid more suitable to the ambient operating environment. Refer to
the following table to determine McCoy Global’s recommendations for gear uid selection.
Gear Fluid Standards
Operating Condition Requirement
-4°F to 41°F (-20°C to 5°C) meets ISO VG100 or AGMA 3EP specications
41°F to 104°F (5°C to 40°C) meets VG150/VG220 or AGMA 4EP/5EP specications
greater than 104°F (40°C) meets VG320 or AGMA 6EP specications
Grease
McCoy Global recommends use of a high-quality EP multi-purpose grease with an NLGI consistency grade of "2" and an NLGI
performance grade of "GC-LB" for general lubrication of bearings and metal-to-metal contact.
McCoy Global recommends thoroughly greasing the equipment before first use as per the lubrication instructions in Section 5.
