Introduction
1.1 SCOPE
This technical manual is the main document supplied by McCoy Global for the equipment identified on Page iii of the
preamble. The intent of this document is to provide descriptions of the systems, installation, commissioning and operating
instructions, maintenance guidelines, spare parts information, and technical drawings and schematics (where applicable).
The OEM-recommended installation, commissioning, operation, maintenance, and troubleshooting instructions are to be
regarded as guidelines, and are not intended to be a comprehensive operating guide for user specific application. Due
to the wide variety of operating conditions it remains the responsibility of each equipment owner to use these guidelines
together with an experienced manager to develop safe operating procedures that conform to American Petroleum
Institute (or equivalent) standards, applicable State/Province or local regulations, and any corporate regulations/
operating practices.

Introduction
1.2.2 General Safe Operation Guidelines (Continued):
The area surrounding the equipment operating area must be clutter-free and free from tripping hazards, or
protruding objects that may snag hoses or cables. Operating surface or drill floor must be kept free of slipping
hazards like grease, oil, water, etc.
Adequate lighting of the work area is required. All warnings, labels, gauges, and signs must be clearly visible.
Equipment components painted green are safe for continuous handling. Areas painted yellow and any other
equipment components that rotate or move are designated as hazardous areas. Contact with those areas must
be avoided during operation.
Always wear all personal protective equipment (PPE) specified by established HSE policies. Follow all safety
guidelines.
Do not open the tong door while the tong is rotating or under load. Doing so may generate a shock load that could
result in catastrophic equipment failure not covered by the manufacturer’s warranty, and may present a hazard to
personnel on the drill floor.
!!
Illustration 1.2.1: Equipment Handling Warnings
See Section 4 for the correct, safe procedure for testing the door switch on a McCoy Global power tong.
Never attempt to clamp to a tubular using incorrectly sized dies. Operators must always use the correct jaw
size equipped with the proper dies. Use of incorrectly size dies poses a hazard to personnel and may damage
equipment. Please see Section 3 of this manual for a list of compatible jaw die kits and replacement dies.
!WARNING
DO NOT OPEN TONG DOOR WHEN TONG IS ROTATING OR UNDER LOAD
!WARNING
NEVER ATTEMPT TO CLAMP ONTO TUBULARS WITH INCORRECTLY SIZED DIES
!WARNING
BY NATURE, STEEL MACHINERY WITH ROTATING AND MOVING PARTS HAS THE POTENTIAL
TO GENERATE IGNITION SOURCES, IE. SPARKS. AS OUTLINED IN THIS MANUAL, SCHEDULED
MAINTENANCE, LUBRICATION, TIMELY REPLACEMENT OF WORN COMPONENTS AND MOST
IMPORTANTLY, ON-SITE RISK ASSESSMENTS WITH STRINGENT STANDARD OPERATING
PROCEDURES ARE ALL REQUIRED TO PREVENT THE POTENTIAL OF SPARK GENERATION.
!WARNING
FAILURE TO FOLLOW THE EQUIPMENT PLACEMENT/RIG-UP PROCEDURES OUTLINED IN THIS
MANUAL MAY LEAVE EQUIPMENT UNGROUNDED AND AT RISK FOR BUILDING A STATIC CHARGE.
ASSESSMENT FOR PROPER GROUNDING MUST BE PERFORMED PRIOR TO OPERATION IN ORDER
TO MITIGATE THE SPARK RISKS ASSOCIATED WITH STATIC DISCHARGE.

Introduction
!DANGER
NEVER STAND BENEATH A SUSPENDED LOAD
!DANGER
ALWAYS MEASURE ELECTRICAL CIRCUITS TO CONFIRM DEACTIVATION BEFORE PROCEEDING WITH
MAINTENANCE
1.2.5 Replacement Parts
All consumable and replacement parts must meet or exceed OEM specifications in order to maintain equipment
integrity. Do not replace protective equipment such as hydraulic switches, circuit breakers, and fuses without first
consulting with McCoy Global. Do not replace electrical or control hardware without consulting with McCoy Global.
Using non-OEM replacement parts without the approval of McCoy Global may void equipment warranty.
1.2.6 Environmental Impact
McCoy Global equipment uses materials that may be harmful to the environment if improperly disposed of
(hydraulic fluid, grease, fuel, electrical components, etc.). Dispose of all materials according to established
environmental protection regulations in conjunction with published federal, state, provincial, and civic legislation.
In all cases 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.
• any legal or other mandatory regulation in force governing accident prevention or environmental
protection.
1.2.3 Rigging and Overhead Lifting
McCoy Global recommends following an industry-accepted standard such as OSHA, ASME B30.9-2006, or
manufacturer’s guidelines when performing any rigging and overhead lifting. Use by untrained persons is
hazardous. Improper use will result in serious injury or death. Do not exceed rated capacity. Slings will fail if
damaged, abused, misused, overused, or improperly maintained. Never stand beneath a suspended load.
1.2.4 Maintenance Safety
All personnel are responsible for performing maintenance tasks in a manner that ensures worker, equipment, and
environmental safety, and may require taking additional steps that are not identified in this section.
Maintenance of equipment shall be performed only by designated qualified maintenance personnel. Do not begin
a maintenance task without the proper tools or materials on hand, or the proper drawings and documentation
necessary.
Isolate the location of the maintenance under way to prevent unaware personnel from inadvertently exposing
themselves to a hazard. Use tape, rope, or signage to clearly indicate “off-limits” area.
Where applicable ensure electrical circuits within the affected equipment are deactivated or de-energized by an
authorized, qualified person and locked out if necessary. Do not disconnect a live electrical circuit unless location
is known to be non-hazardous.
!WARNING
WHEN REPAINTING EQUIPMENT, THE PAINT COAT BEING APPLIED SHOULD NEVER EXCEED 2MM
IN THICKNESS. EXCEEDING THIS THICKNESS MAY FACILITATE STATIC CHARGE BUILDUP AND
PRESENT A POSSIBLE SPARK RISK ASSOCIATED WITH STATIC DISCHARGE.
