Carrying out scheduled maintenance activities on mechanical equipment
Overview
This standard identifies the competences you need to carry out scheduled maintenance activities on mechanical equipment, in accordance with approved procedures. You will be required to carry out scheduled maintenance on a range of mechanical equipment such as machine tools, gearboxes, portable tools, engines, pumps, process control valves, compressors, process plant, conveyers and elevators, lifting and handling devices, transfer equipment, mechanical structures, workholding devices and other company-specific equipment, in order to minimise downtime and ensure that equipment performs at the optimal level and functions to specification.
Your responsibilities will require you to comply with organisational policy and procedures for the maintenance tasks undertaken, and to report any problems with the maintenance process, tools or equipment used that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You must ensure that all tools, equipment and materials used in the maintenance activities are removed from the work area on completion of the activities, and that all necessary job/task documentation is completed accurately and legibly. You will be expected to work to instructions, alone or in conjunction with others, taking personal responsibility for your own actions, and for the quality and accuracy of the work that you carry out.
Your underpinning knowledge will be sufficient to provide a sound basis for your work, and will enable you to adopt an informed approach to applying scheduled maintenance procedures to mechanical equipment. You will have an understanding of the process of implementing scheduled maintenance tasks, the importance of carrying them out at specific times, and of recording the outcomes and actions taken. In addition, you will be expected to report where the outcomes identify the need for further investigation or maintenance work.
You will understand the safety precautions required when carrying out the maintenance tasks, especially those for isolating the equipment. You will also understand your responsibilities for safety, and the importance of taking the necessary safeguards to protect yourself and others in the workplace.
Performance criteria
You must be able to:
- work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
- follow the relevant maintenance schedules to carry out the required work
- carry out the maintenance activities within the limits of your personal authority
- carry out the maintenance activities in the specified sequence and in an agreed time scale
- report any instances where the maintenance activities cannot be fully met or where there are identified defects outside the planned schedule
- complete relevant maintenance records accurately and pass them on to the appropriate person
- dispose of waste materials in accordance with safe working practices and approved procedures
Knowledge and Understanding
You need to know and understand:
- the health and safety requirements of the area in which the scheduled maintenance activities are to take place, and the responsibility these requirements place on you
- the isolation procedure or permit-to-work procedure that applies to the equipment being maintained
- the specific health and safety precautions to be applied during the scheduled maintenance activities, and their effects on others
- the importance of wearing protective clothing and other appropriate safety equipment (PPE) during the maintenance activities
- the hazards associated with carrying out scheduled maintenance activities on mechanical equipment (such as handling oils/greases, stored pressure/force, misuse of tools), and how they can be minimised
- how to obtain and interpret information from job instructions and other documentation used in the maintenance activities (such as drawings, specifications, manufacturers' manuals, servicing schedules, symbols and terminology)
- the various checks to be carried out during the scheduled maintenance procedure
- the procedure for obtaining the consumables to be used during the scheduled maintenance activity
- methods of checking that components are fit for purpose, and the need to replace `lifed' items
- how to check that any replacement components meet the required specification/operating conditions
- how to make appropriate sensory checks (such as sight, sound, smell and touch)
- the appropriate testing instructions to be adopted during the maintenance activity
- how to make adjustments to components/assemblies to ensure they function to specification
- the basic principles of how the equipment functions, its operating sequence, the working purpose of individual units/components and how they interact
- how to complete scheduled maintenance records/logs/reports, in accordance with company policy and procedures
- the equipment operating and control procedures, and how to apply them in order to carry out scheduled maintenance
- the problems that can occur whilst carrying out the scheduled maintenance tasks, and how they can be avoided
- the organisational procedure(s) to be adopted for the safe disposal of waste of all types of materials
- the extent of your own authority and to whom you should report if you have problems that you cannot resolve
