지게차 운전기능사 필기/당일치기. 벼락치기- 이 영상 하나로 끝내세요- 시간 없으신 분들은 꼭 이거라도 보시고 시험장 들어가세요!! 올 인원-합격 직선 코스.

Main ideas / concepts conveyed

• Video purpose: A fast “one-day cram” focused on written exam questions for the Forklift Operator Skills Certification (and related construction machinery management topics). The speaker repeatedly emphasizes these are high-probability / guaranteed-to-appear questions.

Test strategy

• Listen to the summary 2–3 times.
• Pause and choose an answer before the speaker reveals it, because the session is quick.

Core exam themes covered (question-by-question)

Construction machinery business / registration classification

• Business types are divided into categories (e.g., integrated, local/specified, specialized).
• Questions distinguish what counts as a business under the act versus manufacturing (manufacturing generally is not included).

Workplace tool safety & workplace safety rules

• Precautions for using spanners/wrenches, such as correct angle usage and avoiding improper substitutions.
• Hazards like waste oil on floors (slip + fire risk).

Forklift operation fundamentals

• Loading/unloading procedures, mast tilt handling, and lever directions (lift/tilt, forward vs backward actions).
• Unloading requires tilt correction—tilt direction must be adjusted properly upon arrival.
• Driving with a load: key distances and safe practices.
• Parking rules and slope rules; often tested using “incorrect method” style questions.

Hydraulics / mechanical systems

• Directional control valves and concepts like relief/check/accumulator.
• Hydraulic circuit behavior under abnormal conditions (e.g., high conductivity/viscosity leading to increased power loss or overheating).
• Causes of hydraulic pressure drop and oil temperature rise.

Legal/administrative rules (Construction Machinery Management Act + Road Traffic Act)

• License revocation vs suspension criteria:
  • Intentional vs negligent damage distinctions.
  • Missing required tests.
  • Fraudulent acquisition.
  • Operating during suspension.
• Fines and changes in fine rules after inspection-period deadlines.
• Parking/stopping restrictions, traffic signal priority, and “temporary stop / slow down” zones.

Fire classification

• Repeated mapping of classes (A, B, C, etc.) to what they represent (general fires, oil fires, electrical fires, metal fires).

Gas welding / fuel / diesel engine basics

• Gas welding safety: do not use open flames (e.g., matches) when prohibited; leak checking with soapy solution.
• Diesel “not starting” causes:
  • Fuel system issues
  • Starter motor
  • Compression pressure
  • Air in fuel line causing misfiring/shaking

Mechanical components / design knowledge

• Forklift parts (e.g., counterweight, center of load, tilt mechanism, tire carcass).
• Tire tread effects on traction/braking and heat dissipation.

Inspection requirements

• Types of inspections (regular vs unscheduled).
• What is included/excluded from daily checks.

Methodology / instructions presented (detailed)

How to study for the exam while watching

• Repetition: Listen again 2–3 times.
• Active answering loop:
  • When the speaker says to pause:
    • Pause the screen
    • Pick an answer from the choices
    • Resume to compare with the “correct” option
• Focus rule: Treat these as “don’t-miss” exam items; memorize patterns where wording changes but the underlying concept stays the same.

Specific “what to memorize” items (from repeated exam patterns)

• Forklift tilt / unloading concept

  • If you unload at the destination, tilt must be corrected properly (often meaning: don’t unload with the mast tilted the wrong way; adjust tilt accordingly).

• Tool/workplace safety concept

  • Incorrect options usually violate:
    • Correct angle/tool compatibility
    • Prohibitions on hazardous floor practices (e.g., waste oil)
    • Proper glove/gear rules depending on the task

• License admin logic

  • Revocation vs suspension depends on:
    • Intentional damage vs negligent damage
    • Whether the operator failed required tests
    • Fraudulent licensing
    • Operating during suspension

• Inspection logic

  • Regular inspection vs unscheduled inspection (wording may be used to trick you).

• Road Traffic Act priority

  • Police hand signals override traffic lights when given.
  • Right-of-way at intersections typically follows “vehicle on the right” when not otherwise directed.

• Hydraulics abnormality patterns

  • High viscosity / high conductivity tends to increase friction/power loss, and may worsen cooling.
  • Wrong fluid conditions can cause overheating.
  • Relief valve concept: prevents pressure exceeding its set value.
