What the 20 Content Areas Actually Represent
The Manufacturing Skill Standards Council (MSSC) administers the Certified Forklift Technician credential, and the 20 content areas in this guide reproduce MSSC's official CFT key activities. They describe the knowledge and skills a lift truck maintenance and repair technician is expected to command, from reading a hydraulic symbol to diagnosing a no-start condition on an internal combustion truck.
It is worth being precise about what this list is and is not. The 20 entries organize our technical coverage of the credential. They are not a weighted question-allocation blueprint for the Certified Forklift Associate (CFA) assessment, so you should not assume that each domain contributes an equal share of the 92 questions, or that any particular domain is worth a fixed percentage. Treat every domain as fair game and build breadth first.
How the Knowledge Assessment Is Built
Our practice questions and exam-facing content target the prerequisite CFA assessment, which is the knowledge stage you must clear before the hands-on stage. The format facts you should hold in your head:
| Element | What to Know |
|---|---|
| Question count | 92 multiple-choice questions |
| Time limit | 90 minutes |
| Passing requirement | 79% |
| Language | English |
| Reference materials | Closed book |
| Calculator | Personal calculators prohibited; an on-screen four-function calculator is supplied |
| Identification | Valid ID plus your MSSC identification number |
| Retake wait | 15 days after a failed knowledge assessment |
Delivery runs through NOCTI/The Whitener Group, with testing at MSSC-authorized assessment centers and an approved ProctorU remote-proctoring option, per the October 2024 Candidate and Certificant Handbook. For the pass-line math, see CFT Passing Score 2026: Exactly What You Need to Pass, and for scheduling logistics, CFT Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Because the on-screen calculator is only four-function, expect questions where arithmetic is simple but the setup is not, such as working out an electrical relationship or a hydraulic force relationship from supplied values. Know the formulas cold, because you will not have a reference sheet.
Foundation Domains: Domains 1 Through 3
Domain 1: Operator orientation
Understanding how the truck is used so you can interpret operator complaints and distinguish a machine fault from an operating habit.
- Recognizing common operator-reported symptoms
- Understanding controls and instrument indications from the operator's seat
- Knowing where operator responsibility ends and technician responsibility begins
Domain 2: Lift truck fundamentals
The vocabulary and architecture of a lift truck: major assemblies, how power moves through the machine, and how classes of trucks differ.
- Identifying major systems and how they interact
- Differentiating electric, internal combustion, and other power configurations
- Using correct component terminology, since questions assume you speak the language
Domain 3: Basic safety
Safe service practice. Technician safety questions tend to be scenario-driven: what do you do before you open a hydraulic line, work under a raised carriage, or disconnect a battery?
- Lockout/tagout thinking and de-energizing systems before service
- Protecting yourself around stored energy: raised forks, hydraulic pressure, charged batteries
- Personal protective equipment and safe handling of fuels and fluids
These three are the quickest points on the assessment because they are conceptual rather than diagnostic, so lock them down early and keep them fresh with a short recurring review.
Engines, Fuel, Cooling, and Diesel
Four domains cover the internal combustion side of the truck, and they overlap heavily. Studying them as a family is far more efficient than treating them as four separate subjects.
Domain 4: Basic engines
Four-stroke operating principles and the engine's major components, which underpin everything in the fuel, cooling, and electrical-ignition domains.
- The four-stroke cycle and what happens in each stroke
- Core engine components and their functions
- Lubrication fundamentals and how engine condition is judged
Domain 12: Cooling systems
How the engine sheds heat and what fails when it cannot.
- Radiator, thermostat, water pump, hoses, and coolant roles
- Symptoms of overheating versus overcooling
- Routine cooling-system inspection and service
Domain 14: Gasoline & LPG fuel systems
Lift trucks commonly run on gasoline or liquefied petroleum gas, and the assessment treats these systems as a technician specialty.
- Fuel delivery components and how mixture is controlled
- Safe handling of LPG cylinders and fuel system service precautions
- Diagnosing running problems tied to fuel supply
Domain 20: Diesel operation
How diesel combustion differs from spark-ignition operation and what that means for service.
- Compression ignition versus spark ignition
- Diesel fuel system fundamentals
- Starting and running characteristics specific to diesel trucks
Hydraulics, Masts, and Attachments
The lifting function is what makes a lift truck a lift truck, and three domains cover it end to end.
Domain 5: Basic hydraulics
Pumps, valves, cylinders, hoses, and fluid, plus the pressure and flow principles behind them.
- How a hydraulic pump creates flow and why resistance creates pressure
- Control valve and relief valve roles
- Recognizing leaks, slow lift, drift, and noisy operation as symptoms
Domain 9: Masts
The mast assembly, its stages, chains, rollers, and tilt and lift cylinders.
- Mast types and how stages extend
- Chain inspection, adjustment, and wear indicators
- Carriage, rollers, and the relationship between mast condition and lift performance
Domain 10: Basic attachments for lift trucks
Attachments change how the truck handles loads and how the hydraulic system must be configured.
- Common attachment types and their purposes
- How attachments affect capacity and hydraulic demand
- Basic service considerations for attachment-equipped trucks
Hydraulics is a prerequisite concept for Masts, Attachments, and even power steering, so it pays to master Domain 5 before moving on. If you want to gauge where this sits among the hardest content, read How Hard Is the CFT Exam? Complete Difficulty Guide 2026.
Drivetrain, Brakes, and Steering
Domain 13: Front drive axle & differential
Where power reaches the wheels. Lift trucks typically drive through the front axle, which is a distinguishing feature compared with a passenger vehicle.
- Axle construction, differential operation, and wheel-end components
- Lubrication and inspection of the drive axle
- Symptoms of differential and axle problems
Domain 19: Transmissions
How engine or motor power is transferred and controlled for forward and reverse travel.
- Transmission types found on lift trucks
- Fluid checks, filtration, and common failure symptoms
- The relationship between the transmission and the drive axle
Domain 6: Brake systems
The core service-brake and parking-brake knowledge every technician needs.
- Hydraulic brake components and how they operate together
- Inspection and adjustment of friction components
- Diagnosing weak, dragging, or noisy braking
Domain 17: Oil cooled wet disc brakes of electrical and mechanical braking systems
A more specialized brake topic. Wet disc brakes operate in oil, which changes how they wear, how they are cooled, and how they are serviced.
- How oil cooling affects brake life and service intervals
- Differences between wet disc and conventional friction brakes
- How electrical and mechanical braking systems relate on the truck
Domain 18: Steering systems
Lift trucks steer with the rear wheels, which surprises people coming from automotive backgrounds.
- Steering axle layout and linkage
- Hydraulic power steering components
- Diagnosing hard steering, play, and drift
Key Takeaway
Keep Domains 6 and 17 separate in your notes. Conventional brakes and oil-cooled wet disc brakes fail and are serviced differently, and the assessment can test whether you know which is which.
Electrical Domains: Theory, Meters, Batteries, and IC Systems
Four domains make up the electrical cluster, and they build directly on one another. Because electrical diagnosis is where many candidates feel least comfortable, give this cluster extra calendar time.
Domain 7: Basic laws of electricity
The foundation: voltage, current, resistance, and the relationships among them, plus series and parallel circuit behavior.
- Ohm's law and how to apply it with simple arithmetic
- Series versus parallel circuit characteristics
- Power relationships and why circuits heat up under load
Domain 15: Use meters for testing electrical circuits & components
The practical application of Domain 7. A meter reading only means something if you know how to take it and what it should be.
- Measuring voltage, current, and resistance correctly
- Meter placement in a circuit and the safety implications of each measurement
- Interpreting readings to isolate an open, short, or high-resistance fault
Domain 8: Batteries
Battery knowledge matters on both electric trucks, where the battery is the power source, and internal combustion trucks, where it supports starting and accessories.
- Battery construction, state of charge, and testing
- Safe charging and handling practices
- Maintenance routines and signs of failing cells
Domain 16: IC electrical systems
The electrical systems of internal combustion trucks: starting, charging, ignition, and lighting circuits.
- Starter and charging system operation
- Ignition system function on spark-ignited engines
- Applying meter testing from Domain 15 to starting and charging faults
Notice how a single scenario can touch all four: a truck that will not start requires battery knowledge, a meter test, an understanding of the starting circuit, and the underlying electrical laws. Practicing integrated scenarios, rather than isolated facts, is the best preparation. Our practice tests at cftexam.com let you drill these in a multiple-choice format that mirrors the assessment.
Components and Symbols: The Reading Skill
Domain 11: Components & symbols
Technicians work from schematics, and this domain is about reading them. Electrical and hydraulic diagrams use standardized symbols, and you need to recognize them quickly.
- Identifying electrical symbols: switches, relays, fuses, motors, resistors, batteries
- Identifying hydraulic symbols: pumps, cylinders, valves, filters, reservoirs
- Tracing a path through a diagram to predict system behavior
This domain has an unusual property: it is almost entirely visual recall. Flashcards that show a symbol and ask for its name and function are far more effective here than reading prose. Practice until recognition is instant, because every electrical and hydraulic domain above assumes you can already read the diagram.
Sequencing the Domains in Your Study Plan
The right order of study follows the dependencies between domains rather than their numbering. Here is one sequence that respects those dependencies. For a broader preparation framework, see CFT Study Guide 2026: How to Pass on Your First Attempt.
Orientation and language
- Domains 1, 2, and 3: operator context, fundamentals, safety
- Domain 11: begin symbol flashcards, which you will review daily from here on
Electrical foundations
- Domain 7 (laws of electricity), then Domain 15 (meters)
- Work simple circuit calculations with only a four-function calculator
Power sources and electrical systems
- Domain 8 (batteries), then Domain 16 (IC electrical systems)
- Run integrated no-start scenarios across all four electrical domains
Engines and fuels
- Domain 4, then Domains 12, 14, and 20
- Build the gasoline/LPG/diesel comparison table
Hydraulics and lifting
- Domain 5 first, then Domains 9 and 10
- Connect hydraulic principles to mast and attachment behavior
Drivetrain, brakes, steering, and review
- Domains 13, 19, 6, 17, and 18
- Take full-length timed practice sets at our practice test site and revisit weak domains
The logic is simple: electricity precedes the electrical systems that depend on it, and basic hydraulics precedes masts and attachments. If you already work in a shop and are strong in mechanical areas, compress those weeks and spend the time on electrical diagnosis and symbol reading instead. Adjust the schedule to your own background and to your available test windows.
Where the Domains Meet the Hands-On Stage
Passing the CFA knowledge assessment does not by itself award the Certified Forklift Technician credential. After CFA, candidates must demonstrate the required hands-on tasks to an instructor. In practice, the 20 domains are the same body of knowledge you will be applying with tools in hand, so the work you put into diagnostic reasoning pays off twice.
Some practical points about the pathway:
- There are no mandatory education or work-experience prerequisites for CFA, though hands-on familiarity with trucks will make the technical domains much easier. See CFT Requirements 2026: Eligibility, Prerequisites & How to Qualify.
- MSSC offers an optional 55-hour online course. CFA must be passed before the CFT hands-on stage. For cost mechanics, see CFT Certification Cost 2026: Complete Pricing Breakdown.
- If you fail the knowledge assessment, a 15-day wait applies before you can retest, so a failed attempt costs you at least two weeks. Check the exact cutoff in CFT Pass Rate 2026: What the Data Shows context and prepare to pass the first time.
Frequently Asked Questions
The 20 entries reproduce MSSC's official CFT key activities and organize our technical coverage. They are not a weighted CFA question-allocation blueprint, so do not assume equal or fixed weighting. Study all 20 for breadth rather than gambling on a few.
Start with the foundations (Domains 1 through 3), then Domain 7 (laws of electricity) and Domain 5 (basic hydraulics), because later electrical and lifting domains build on them. Begin Domain 11 symbol practice early and keep reviewing it.
No. The knowledge assessment (CFA) is a prerequisite stage. You must pass it and then demonstrate the required hands-on tasks to an instructor to earn the full CFT credential.
It has 92 multiple-choice questions in English, a 90-minute time limit, and a 79% passing requirement. It is closed book, personal calculators are prohibited, and an on-screen four-function calculator is provided. See the passing score guide for more detail.
No. Certified Forklift Technician is a maintenance-and-repair technician credential. Operator orientation appears as Domain 1, but the credential centers on servicing, diagnosing, and repairing lift trucks rather than driving them.
