ISO 8152:1984

Overview

ISO 8152:1984 - Earth-moving machinery: Operation and maintenance - Training of mechanics provides guidance on the content, structure and delivery of training for mechanics who maintain and service earth‑moving machinery. It applies to all machine types defined in ISO 6165 and is explicitly a training guide - it does not prescribe procedures for assessing competence or proficiency, which remain subject to local and national regulations.

Key topics and requirements

• Training scope and structure
  • Minimum normal training period: preferably not less than three years, with an optional fourth year for advanced or specialized instruction.
  • Probationary period: initial three months (or longer where practical) to confirm aptitude.
  • Suggested phases: Basic (1 year), General (≈2 years), Optional advanced (1 year).
• Training locations and methods
  • Recommended venues: training workshop, depot/repair workshop, site maintenance (field) workshop.
  • Mix of lectures/demonstrations, supervised practical work, and technical college attendance (recommended ~40 working days/year during general training).
• Safety and safety culture
  • Safety must be integrated into every part of training: local/national regulations, PPE, machine guards/shields, emergency immobilization, safe handling of hydraulic/air systems and flammable liquids, tyre inflation safety (protective cages), lifting methods, and fire prevention.
• Practical technical topics
  • Familiarization with a wide range of machines (see ISO 6165) and operator/service manuals (ISO 6750).
  • Basic mechanisms (engines, transmissions, hydraulics), servicing procedures, lubrication, use of hand tools and simple machine tools (lathes, drill presses).
  • Measuring instruments: micrometers, calipers, verniers, torque wrenches, compression gauges and instruments referenced in ISO 6012.
  • Basic fitting, welding and brazing, material properties, spare parts identification and procurement, elementary fault diagnosis and routine repairs.
• Ongoing development
  • Emphasis on on‑the‑job experience, refresher and modular specialist courses throughout a mechanic’s working life.

Applications and users

• Useful as a reference for:
  • Employers and fleet managers of construction and earth‑moving equipment
  • Vocational and technical colleges designing maintenance curricula
  • Training providers and apprenticeships for mechanics
  • Equipment manufacturers and dealers producing service training
  • Safety officers and maintenance supervisors implementing site training programs
• Practical value: helps structure multi‑year apprenticeship programs, define core practical competencies, and integrate safety and manuals into mechanic training for earth‑moving machinery.
