Competency in Removing and Replacing Lift Truck Electrical Units and Components
This element assesses a learner's ability to safely and competently remove and replace electrical units and components on lift trucks, ensuring adherence to manufacturer specifications and health & safety regulations. It covers interpreting technical data, selecting correct tools, performing systematic disconnection and reinstallation, and verifying functionality post-service. The emphasis is on practical competence in maintaining electrical systems critical to lift truck operation.
Assessment criteria
Topic Overview
The IMI Level 2 Diploma in Lift Truck Maintenance and Repair Competence is a vocational qualification designed for individuals working in the lift truck industry. It covers the essential skills and knowledge required to maintain, service, and repair counterbalance lift trucks up to 5 tonnes capacity. This diploma is part of the Institute of the Motor Industry's occupational qualifications and is recognised by employers across the UK. The course focuses on practical competence in areas such as engine systems, hydraulic systems, electrical systems, and chassis components, ensuring you can diagnose faults and carry out repairs safely and efficiently.
This qualification is crucial for anyone pursuing a career as a lift truck technician. Lift trucks are vital in warehouses, factories, and logistics centres, and their safe operation depends on regular maintenance and prompt repairs. By mastering this diploma, you will gain the skills to keep these machines running reliably, reducing downtime and preventing accidents. The course also emphasises health and safety regulations, including LOLER (Lifting Operations and Lifting Equipment Regulations) and PUWER (Provision and Use of Work Equipment Regulations), which are essential for compliance in the workplace.
Within the wider Motor Vehicle & Transport sector, this diploma sits alongside other IMI qualifications for vehicle maintenance and repair. It provides a specialist pathway for those focusing on industrial vehicles rather than cars or vans. The competence-based assessment means you will be evaluated on your practical abilities in a real or simulated workshop environment, making the qualification directly relevant to your job. Successful completion can lead to advanced qualifications, such as the IMI Level 3 Diploma in Lift Truck Maintenance and Repair, or career progression to supervisory roles.
Key Concepts
Core ideas you must understand for this topic
- →Internal combustion engine systems: Understanding the operation, maintenance, and repair of petrol, diesel, and LPG engines used in lift trucks, including fuel systems, ignition systems, and cooling systems.
- →Hydraulic systems: Knowledge of hydraulic pumps, valves, cylinders, and hoses; how they control lifting, tilting, and steering; and common faults like leaks or pressure loss.
- →Electrical systems: Familiarity with batteries, alternators, starters, wiring harnesses, and electronic control units (ECUs) used in lift trucks, including diagnostics using multimeters and scan tools.
- →Chassis and running gear: Inspection and repair of frames, axles, wheels, tyres, brakes, and steering components, ensuring stability and safe operation.
- →Health and safety regulations: Compliance with LOLER, PUWER, COSHH, and risk assessment procedures when working on lift trucks, including safe isolation and use of lifting equipment.
Learning Objectives
What you need to know and understand
- Be able to work safely when carrying out removal and replacement activities, Be able to use relevant information to carry out the task, Be able to use appropriate tools and equipment, Be able to carry out removal and replacement of lift truck electrical units and components., Be able to record information and make suitable recommendations
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating systematic isolation of electrical power (battery disconnection) and adherence to relevant lock-out/tag-out procedures before commencing work.
- Expect clear evidence of using manufacturer manuals or digital schematics to identify correct component locations, torque settings, and wiring routes.
- Assess proper selection and use of insulated hand tools, multimeters, and diagnostic equipment specific to the electrical unit being replaced.
- Look for methodical removal techniques: labelling or photographing connections prior to disassembly, and careful handling to avoid damage to plugs, pins, or harnesses.
- Credit recording of pre- and post-repair checks, including resistance/voltage readings and functional tests, with accurate documentation of findings and recommendations for further action if needed.
Assessment Guidance
Guidance for achieving higher grades
- 💡During practical assessments, always verbalise or log your safety checks—assessors may not observe every action, but documented evidence counts.
- 💡Before starting any task, cross-reference the job card with the vehicle’s technical data to ensure you have the correct replacement part and understand the procedure.
- 💡After replacing a component, perform a full functionality test and record the results; if a fault persists, note it clearly and recommend further diagnostics rather than assuming the fix is complete.
- 💡Always refer to the manufacturer's service manual for specific torque settings, fluid types, and procedures. Examiners look for evidence that you can follow technical data accurately.
- 💡When demonstrating a repair, explain each step aloud to show your understanding. For example, 'I am checking the hydraulic fluid level because low fluid can cause jerky lifting.' This shows competence beyond just doing the task.
- 💡Pay close attention to health and safety throughout your assessment. Use correct PPE, isolate power sources, and secure the lift truck on level ground. A safety breach can result in an automatic fail.
Common Mistakes
Common errors to avoid in your coursework
- Failing to fully de-energise the system by not disconnecting the battery negative terminal first, risking short circuits or personal injury.
- Using incorrect tools (e.g., uninsulated pliers on live circuits) or non-specialised equipment that can damage delicate connectors or terminals.
- Neglecting to note or photograph wiring configurations before removal, leading to misconnection during reinstallation (e.g., reversed polarity on motors).
- Over-tightening or under-tightening electrical fasteners, which can cause terminal damage or loose connections leading to intermittent faults.
- Misconception: Lift truck engines are the same as car engines. Correction: While similar in principle, lift truck engines are often designed for continuous low-speed operation and may have different cooling and exhaust systems. They also frequently run on LPG, which requires specific knowledge of vaporisers and regulators.
- Misconception: Hydraulic faults are always caused by pump failure. Correction: Many hydraulic issues stem from contaminated fluid, blocked filters, or worn seals. Always check fluid condition and filter before replacing the pump.
- Misconception: Electrical diagnostics are too complex for Level 2. Correction: At Level 2, you are expected to use basic test equipment like multimeters to check voltage, continuity, and resistance. Understanding simple circuits and following wiring diagrams is achievable with practice.
