Year 2 Exam Study Guide — master what the exam actually tests, concept by concept.
Heavy equipment and vehicles are governed by federal and provincial regulations covering emissions, safety systems, weights and dimensions, and operator certification. Knowing these standards protects you legally and ensures the machines you service are roadworthy and safe.
Slope limit: exceed angle = tipover risk; operate perpendicular to contours when possible. Memorize this formula and practise substituting values — exam questions often give you three variables and ask you to solve for the fourth.
exceed angle = tipover risk
Engine displacement, gear ratios, hydraulic pressure, electrical resistance, and fuel delivery rates all require calculation. These questions test your mechanical math: knowing which formula to apply, what units to use, and how to check your work.
Slot dozing: cut narrow path, load from sides into slot; moves more volume per pass. Material selection directly affects performance, code compliance, and longevity. Using the wrong type can fail an inspection or create a hazard down the line.
Pitch: tilt blade forward (dig), back (carry); control spillage, penetration. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Vehicle systems use a wide range of specialty materials, fluids, and components that must meet OEM specifications. This section covers proper tool selection, component identification, and the material properties that determine service intervals and replacement requirements.
Blades: straight (general), angle (windrow), U (carry), semi-U (balance). Material selection directly affects performance, code compliance, and longevity. Using the wrong type can fail an inspection or create a hazard down the line.
Ripper: penetrate rock, fracture, pull ripped material forward; multiple passes needed. Safety regulations exist because the consequences of ignoring them are severe — injury, death, or legal liability. Know these requirements the way you know your own name.
Stockpile: layer material, angle blade to build cone; stable, efficient storage. Material selection directly affects performance, code compliance, and longevity. Using the wrong type can fail an inspection or create a hazard down the line.
Grading: modern = GPS/laser control ±0.1 foot; establishes proper drainage/slopes. Memorize this formula and practise substituting values — exam questions often give you three variables and ask you to solve for the fourth.
modern = GPS/laser control ±0
Diagnostic and repair procedures are systematic — skip a step and you'll miss the root cause. This section covers the proper approach to vehicle diagnosis, the sequence of mechanical repairs, and the testing methods that confirm a fix actually fixed the problem.
Final drives: monitor for noise, check oil, adjust clearances; failure = immobile equipment. Memorize this formula and practise substituting values — exam questions often give you three variables and ask you to solve for the fourth.
failure = immobile equipment
Track sag: measure between frames at mid-span; adjust if too loose (wear) or tight (damage). On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Assessment: excessive play, cracked grousers, worn sprocket teeth = parts replacement. Memorize this formula and practise substituting values — exam questions often give you three variables and ask you to solve for the fourth.
worn sprocket teeth = parts replacement
