Study Guide

Cheat Sheet

  1. Preventive Maintenance Scheduling -

    Master the use of Mean Time Between Failures (MTBF) and Mean Time To Repair (MTTR) to plan maintenance intervals effectively. Apply the formula Availability = MTBF / (MTBF + MTTR) (source: IEEE Reliability Society) when answering maintenance test questions on system uptime. Remember the mnemonic "B4, After, Repair" to recall Lifecycle checks: before failure and after repair.

  2. Lockout-Tagout Procedures -

    Know OSHA's 29 CFR 1910.147 standard steps: prepare, shut down, isolate energy, apply locks/tags, verify isolation. In maintenance practice tests, identify each phase correctly to prevent unexpected startups. Use the phrase "Stop, Isolate, Verify, Notify" to lock in the correct sequence.

  3. Root Cause Analysis Techniques -

    Familiarize yourself with the 5 Whysâ„¢ method and Ishikawa fishbone diagrams (source: ASQ) to pinpoint failure origins in troubleshooting scenarios. Many maintenance skills test questions present layered faults - keep asking "Why?" until you reach the fundamental cause. A tip: chart your answers on a fishbone to visualize categories like Materials, Methods, and Machinery.

  4. Condition Monitoring Methods -

    Review key non-destructive techniques - vibration analysis, infrared thermography, and oil particle counting (ISO 18436). Maintenance assessment tests often include interpreting vibration spectra or thermal images to spot bearing wear. Think "VIS" (Vibration, Infrared, Spectroscopy) as a quick recall for condition checks.

  5. Lubrication Fundamentals -

    Understand grease vs. oil selection, viscosity grades (ISO VG numbers), and re-lubrication intervals from the SKF Lubrication Handbook. Practice maintenance technician assessment test questions on calculating grease refill frequency using the Rule of 8: refill at 1/3, 2/3, full life. Mnemonic "VILL" (Viscosity, Interval, Lubricant type, Location) helps you ace related quiz items.
