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 approved eye wear and

footwear, 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

activation. Notify operations when maintenance procedures are complete and equipment functionality is restored.
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.
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
McCoy Drilling & Completions recommends that disconnection of hydraulic connectors be performed with the power unit off and the

hydraulic circuit depressurized.
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 prop-

erly cleaned. 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 informa-

tion 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 Drilling & Completions 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 experience and best estimate of when your equipment is due for

this maintenance.
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 Drilling & Completions recommends as part of their recommended

procedures. Users of this equipment may choose to perform or ignore these additional tasks at their discretion.
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. 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.
