Restoring service lifts to service by replacing or repairing components
Overview
This standard identifies the competences you need to restore service lifts to usable condition by repairing or replacing components, in accordance with approved procedures. You will be required to restore a range of service lifts, such as traction, hydraulic, and direct drive to operational condition, by repairing or replacing assemblies/sub-assemblies and components. You will also be required to select the appropriate equipment to use, based on the nature of the repair, and the operations to be carried out.
Your responsibilities will require you to comply with organisational policy and procedures for the repair/replacement activities undertaken, and to report any problems with these activities, or with the tools, equipment or materials used, that you cannot personally resolve or are outside your permitted authority, to the relevant people. 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 provide an informed approach to applying component repair/replacement procedures to service lifts. You will have an understanding of the function and operating conditions of the various components, in sufficient depth to determine if a suitable repair can be made, and to ensure that any repairs or replacements carried out are safe and practical in operation.
You will understand the safety precautions required when carrying out the repair/replacement activity, 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:
P1 work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines

K9 the basic principles of how the equipment functions, its operating sequence, the working purpose of individual units/components and how they interact
K10 the uses of mechanical and electrical measuring devices
K11 how to make adjustments to components/assemblies to ensure that they function correctly
K12 the importance of making checks before running the equipment under power
K13 how to check that tools and equipment are free from damage or defects, and are in a safe, tested and usable condition
K14 the importance of preparing documentation and/or reports following the replacement/repairing activity, and how to generate them
K15 the equipment operating and control procedures to be applied during the repair/replacement activity
K16 how to use lifting and handling equipment in the repair/replacement process
K17 the issues that can occur when carrying out repairs to service lifts, and what to do if they occur
K18 the organisational procedure(s) to be adopted for the safe disposal of waste of all types of materials
K19 the extent of your own responsibility and to whom you should report if you have problems that you cannot resolve
