Restoring stairlifts to service by replacing or repairing components

​

This standard identifies the competences you need to restore stairlifts to usable condition by component repair or replacement, in accordance with approved procedures. You will be required to restore a variety of different types of stairlifts, such as straight, curved and hinged, 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 activity and the operations that will need to be carried out.

Your responsibilities will require you to comply with organisational policy and procedures for the repairing or 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 stairlift component repair or replacement procedures safely. You will have an understanding of the function and operating conditions of the components, in sufficient depth to determine if the components require replacing or can be repaired. You will also understand the organisational policy on repairing or replacing components, and its application.

You will understand the safety precautions required when carrying out the repair or component 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.

---

1. work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
2. follow the relevant specifications for the component to be repaired
3. prepare the component for repair
4. carry out the repairs within agreed timescale using approved materials and components and methods and procedures
5. ensure that the repaired component meets the specified operating conditions
6. produce accurate and complete records of all repair work carried out

---

1. the health and safety requirements of the area in which the repairing or replacing activity is to take place, and the responsibility these requirements place on you
2. the isolation and/or lock-off or permit-to-work procedure that applies
3. the specific health and safety precautions to be applied during the repair/replacement procedure, and their effects on others
4. the importance of wearing protective clothing and other appropriate safety equipment (PPE) during repairing activities
5. the hazards associated with carrying out stairlift repairs (handling oils, greases, stored pressure/force, misuse of tools, using damaged or badly maintained tools and equipment, not following laid-down servicing procedures), and how to minimise them
6. what constitutes a hazardous voltage and how to recognise victims of electric shock
7. how to reduce the risks of a phase to earth shock (such as insulated tools, rubber mating and isolating transformers)
8. where to obtain, and how to interpret job instructions and other relevant documents used in the maintenance activities (such as drawings, specifications, manufacturers' manuals, maintenance schedules)
9. the methods, techniques and company procedures to be followed for restoring stairlifts to service
10. the inspection and safety checks required, and the importance of following them correctly during replacement/repairing activities
11. the methods and techniques used to dismantle/assemble stairlift equipment (such as visual examination, dismantling equipment, replacing damaged/defective components, setting, aligning and adjusting and functionally testing)
12. methods of checking that components are fit for purpose, and how to identify defects and wear characteristics
13. the basic principles of how the equipment functions, its operating sequence, the working purpose of individual units/components and how they interact
14. the uses of mechanical and electrical measuring devices
15. how to make adjustments to components/assemblies to ensure that they function correctly (such as working clearance, setting travel, running and sliding conditions)
16. the importance of making visual checks before running the equipment under power
17. how to check that tools and equipment are free from damage or defects, are in a safe and usable condition, and are configured correctly for the intended purpose
18. the importance of completing replacement/repair documentation correctly
19. the equipment operating and control procedures to be applied during the repair/replacement activity
20. how to apply manual handling techniques when restoring stairlifts to service
21. the problems that can occur when repairing or replacing stairlift components, and what to do if they occur
22. the organisational procedure(s) to be adopted for the safe disposal of waste of all types of materials
23. the extent of your own authority and to whom you should report if you have a problem that you cannot resolve
