Industrial Maintenance Course

Lesson 1 • Hand Tools and Measuring Instruments

Identifies common hand tools, torque wrenches, and precision measuring instruments used in industrial settings. Proper tool use prevents equipment damage and ensures accurate repairs.

Lesson 2 • Maintenance Documentation and Work Orders

Introduces work order systems, maintenance logs, and equipment history records. Accurate documentation drives data-driven decisions covered in later chapters.

Lesson 3 • Roles and Responsibilities in Maintenance

Defines the maintenance technician's role within plant operations and the maintenance department hierarchy. Establishes accountability structures that underpin all subsequent technical training.

Lesson 4 • Industrial Safety Fundamentals

Covers lockout/tagout, personal protective equipment, and hazard communication standards. Safety compliance is the non-negotiable baseline for all hands-on maintenance tasks.

Lesson 1 • Shaft Alignment Techniques

Teaches dial indicator and laser alignment methods for coupled shafts and belt drives. Misalignment is a leading cause of premature bearing and seal failure.

Lesson 2 • Bearings: Types, Failure, and Replacement

Covers rolling-element and plain bearing types, failure modes, and correct installation techniques. Bearing failures are among the most common causes of unplanned downtime.

Lesson 3 • Couplings and Clutches

Identifies flexible, rigid, and fluid coupling types and their maintenance requirements. Clutch adjustment and coupling selection directly affect drivetrain reliability.

Lesson 4 • Belt, Chain, and Gear Drives

Explains V-belt, synchronous belt, roller chain, and gear drive maintenance procedures. Correct tensioning and lubrication extend drive life and reduce energy consumption.

Lesson 1 • Motors: Types, Wiring, and Testing

Covers AC induction, DC, and single-phase motor construction, wiring configurations, and diagnostic testing. Motor faults account for a large share of electrical maintenance calls.

Lesson 2 • Variable Frequency Drives

Explains VFD operating principles, parameter setup, and common fault codes. VFDs are standard on modern industrial equipment and require specific maintenance practices.

Lesson 3 • Motor Control Circuits

Teaches ladder logic diagrams, contactors, overload relays, and control circuit wiring for motor starters. Control circuit knowledge is essential for troubleshooting automated equipment.

Lesson 4 • Industrial Wiring and Panel Maintenance

Covers conduit installation, wire sizing, terminal connections, and control panel inspection. Proper panel maintenance prevents nuisance trips and electrical failures.

Lesson 1 • Pneumatic Components and Circuits

Covers compressors, FRL units, actuators, and solenoid valves in pneumatic circuits. Pneumatic systems power a wide range of industrial automation and tooling applications.

Lesson 2 • Hydraulic Fluid and Contamination Control

Explains fluid viscosity selection, contamination sources, and filtration standards for hydraulic systems. Contamination is the primary cause of hydraulic component failure.

Lesson 3 • Fluid Power Principles

Introduces Pascal's law, flow, pressure, and work concepts for both hydraulic and pneumatic circuits. These principles are the analytical foundation for all fluid power troubleshooting.

Lesson 4 • Hydraulic Components and Circuits

Covers pumps, cylinders, directional control valves, and relief valves in hydraulic circuits. Component identification enables accurate fault isolation and parts ordering.

Lesson 1 • Reliability-Centered Maintenance Concepts

Introduces RCM logic, failure mode analysis, and task selection criteria for optimizing maintenance strategies. RCM thinking elevates technicians from task executors to reliability contributors.

Lesson 2 • Thermography and Ultrasound Inspection

Covers infrared thermography for electrical and mechanical inspections and ultrasound for leak and bearing detection. These non-contact methods find faults without interrupting production.

Lesson 3 • Preventive Maintenance Program Design

Covers task identification, frequency setting, and resource allocation for a structured PM program. A well-designed PM program is the backbone of equipment reliability.

Lesson 4 • Lubrication Management

Explains lubricant types, application methods, and contamination control for rotating and sliding equipment. Correct lubrication is the single highest-impact PM activity.

Lesson 1 • Process Variables and Sensor Types

Covers temperature, pressure, flow, and level measurement principles and the sensors used for each. Understanding sensor physics is prerequisite to calibration and troubleshooting.

Lesson 2 • Basic PLC Interaction for Maintenance

Introduces PLC hardware, I/O status monitoring, and fault diagnostics without programming. Maintenance technicians use PLC tools daily to isolate faults in automated systems.

Lesson 3 • Instrument Calibration Procedures

Teaches zero, span, and linearity calibration for analog and smart transmitters using calibration standards. Calibrated instruments ensure process quality and regulatory compliance.

Lesson 4 • Control Valves and Actuators

Covers globe, ball, and butterfly control valve construction, actuator types, and positioner calibration. Control valves are the final control element in most process loops.

Lesson 1 • MIG and Stick Welding Techniques

Teaches MIG (GMAW) and stick (SMAW) welding parameters, joint preparation, and bead quality for maintenance repairs. These two processes cover the majority of industrial repair welding.

Lesson 2 • Rigging and Equipment Handling

Covers sling types, hitch configurations, load calculations, and crane hand signals for moving heavy equipment. Safe rigging is essential during equipment removal and installation.

Lesson 3 • Structural and Equipment Repair Methods

Applies welding and fabrication skills to repair frames, guards, brackets, and worn equipment surfaces. Repair quality directly affects equipment safety and service life.

Lesson 4 • Welding Safety and Equipment Setup

Covers welding hazards, ventilation requirements, fire watch duties, and equipment setup for MIG, TIG, and stick processes. Safe setup is mandatory before any welding task begins.

Lesson 1 • Systematic Troubleshooting Methodology

Teaches a structured, evidence-based diagnostic process applicable to mechanical, electrical, and fluid power faults. A repeatable method reduces diagnostic time and repeat failures.

Lesson 2 • Continuous Improvement in Maintenance

Applies Kaizen, 5S, and visual management principles to the maintenance shop and plant floor. Continuous improvement sustains reliability gains achieved through technical training.

Lesson 3 • Root Cause Analysis Techniques

Covers 5-Why analysis, fishbone diagrams, and fault tree analysis for identifying failure root causes. RCA findings drive corrective actions that prevent recurrence.

Lesson 4 • Maintenance Key Performance Indicators

Introduces OEE, MTBF, MTTR, and PM compliance metrics and how to calculate and interpret them. KPIs translate maintenance activity into business performance language.
