McCoy Completions & Drilling recognizes that minor on-site repairs and modifications are required to maintain peak operating condition of your
equipment, or to match your equipment with the operating environment. Examples of minor repairs are
● replacement of damaged hydraulic hoses and fittings.
● replacement of malfunctioning pressure gauges and valves.
● replacement of door spring stop cylinders
● replacement of fasteners
Any replaced component must be an identical component supplied by McCoy Completions & Drilling. Replaced fasteners must be Grade 8 or
equivalent, or whatever fastener is specified by McCoy.

GENERAL MAINTENANCE SAFETY PRACTICES
The practices identified here are intended as a guideline. All personnel are responsible for performing their tasks in a manner that ensures
worker, equipment, and environmental safety, and may require taking additional steps that are not identified in this section.
Equipment maintenance shall be performed only by designated qualified maintenance personnel. Wear all personal protective equipment
(PPE) specified by your company's HSE policy, and follow all of your company's safety guidelines. Do not begin a maintenance task
without the proper tools or materials on hand, or the proper drawings and documentation necessary.
Schedule planned maintenance with operators to avoid conflicts, unnecessary downtime, and the danger of accidental equipment activa-
tion. Notify operations when maintenance procedures are complete and equipment functionality is restored and tested.
If on-site maintenance must be performed (in other words, if equipment cannot be transported to a controlled maintenance facility) isolate
the location of the maintenance to prevent unaware personnel from inadvertently exposing themselves to a hazard. Use tape, rope, or
signage to clearly indicate "off-limits" area.
Replacement of large, heavy individual parts and/or heavy structural components must be performed using an approved lifting device of
sufficient lifting capacity. Use care when attaching the lifting device, and safeguard area to avoid endangering personnel or equipment.
All spare parts must meet or exceed OEM specifications in order to maintain equipment integrity, especially protective equipment.
DO NOT PERFORM MAINTENANCE UNTIL TUBULAR CONNECTION EQUIPMENT HAS BEEN COM-
PLETELY ISOLATED FROM HYDRAULIC POWER
Your equipment uses materials that may be harmful to the environment if improperly disposed of (hydraulic fluid, grease, etc.). Dispose
of all materials according to your company's proscribed environmental protection regulations.
B.
CLEANING
Clean tong thoroughly cleaned with a good petroleum-based cleaning agent after each job, prior to storage. Farr® recommends that
the motor and valve assembly be periodically removed, along with the top tong plate, so that guides, rollers and gears can be properly
cleaned (see Section 3.H, Overhaul). Ensure that cleaning solvents and chemicals are captured to prevent environmental contamination,
and dispose of all materials according to your company's proscribed environmental protection regulations.
C.
PREVENTIVE MAINTENANCE PRACTICES
Regular maintenance programs are necessary, and must be established to assure safe, dependable operation of your Hydraulic Tubular
Connection System and to avoid costly breakdown maintenance. The following maintenance procedures provides information required to
properly maintain your equipment. Your equipment may require more, or less maintenance depending upon the frequency of use and the
field conditions under which your equipment operates. These maintenance procedures are designed for equipment operating at 10°C to
35°C ambient temperature for 10 hours per day. McCoy recommends that the inspection and maintenance procedures in this section be
performed as recommended in the maintenance checklists (see Appendices), or in conjunction with your maintenance foreman's experi-
ence and best estimate of when your equipment is due for this maintenance.
Manufacturers of purchased components included with your hydraulic tubular connection equipment (for example: motors, valves, etc.)
may specify maintenance tasks and intervals over and above what McCoy recommends as part of their recommended procedures. Users
of this equipment may choose to perform or ignore these additional tasks at their discretion.
Filtration of the hydraulic fluid must be 10 microns or better. Premature fouling of particulate filters within your prime mover or ancillary
hydraulic power unit requires immediate hydraulic fluid laboratory analysis to prevent premature wear of hydraulic system due to high
levels of wear metals in the fluid.
McCoy Drilling & Completions recommends tracking all maintenance activity including the lubrication schedule and replacement of
hydraulic hoses. This may be a simple as keeping a paper log, or using a software-based maintenance tracking utility. A maintenance log
is a valuable tool that can be used for easily retrieving maintenance history or identifying trends that require correction.
