They must be followed at all times

They are only recommendations

 

Correct Answer: C. They must be followed at all times

 

2. Why should the engine be switched off before leaving the operator’s seat?

 

To prevent unintentional movement of the roller

To comply with regulations

To save fuel

To demonstrate operator control

 

Correct Answer: A. To prevent unintentional movement of the roller

 

 

 

3. What potential consequence is mentioned if voids or soft, weak areas are not checked before compaction?

 

Improved roller performance

Increased compaction efficiency

Enhanced operator comfort

Roller overturning

 

Correct Answer: D. Roller overturning

 

4. What potential issue is mentioned if a roller is parked on soft ground?

 

Improved compaction efficiency

The roller may become overheated

The machine can sink and damage the ground

The roller may experience increased vibration

 

Correct Answer: C. The machine can sink and damage the ground

 

5. When should the articulation bar be removed from the roller?

 

During routine pre-use checks

Before the roller is driven off the transporting vehicle

Immediately upon arrival at the site

After the roller completes its compaction work

 

Correct Answer: B. Before the roller is driven off the transporting vehicle

 

6. Why must full all-round observation be undertaken before reversing a roller?

 

To prevent accidents and injuries

To comply with regulations

To show off operator skills

It is not necessary

 

Correct Answer: A. To prevent accidents and injuries

 

7. How does compaction occur?

 

Via the weight of the roller acting through the drum onto the ground

Through the use of vibration only

By applying heat to the ground surface

Through the use of chemicals sprayed onto the ground

 

Correct Answer: A. Via the weight of the roller acting through the drum onto the ground

 

8. What potential consequence is mentioned if the roller’s center of gravity moves sideways and exceeds the width of the drum on a steep slope?

 

Increased roller stability

Roller overturn

Improved operator visibility

Enhanced roller control

 

Correct Answer: B. Roller overturn

 

9. What caution is given specifically about timber ramps?

 

Timber ramps are the preferred choice for roller access

Timber ramps must be avoided at all costs

Timber ramps can break due to the weight of the roller

Timber ramps are suitable for any roller weight

 

Correct Answer: C. Timber ramps can break due to the weight of the roller

 

10. What is highlighted as a cause of possible instability when the roller is being driven along a slope?

 

Low roller speed

Excessive fuel consumption

Lack of operator experience

Slope is too steep

 

Correct Answer: D. Slope is too steep

 

11. What potential effects on others could occur if the engine of a ride-on roller was left running?

 

Exhaust fumes entering the work area

Improved communication

Increased safety

Better work coordination

 

Correct Answer: A. Exhaust fumes entering the work area

 

12. What is emphasized as a crucial step for the roller driver at the end of a run before reversing?

 

Increasing the speed of the roller

Checking fuel levels

Ensuring no vehicles or personnel are in the reversing path

Testing the reversing warning system

 

Correct Answer: C. Ensuring no vehicles or personnel are in the reversing path

 

13. How is it advised for the roller to be driven up a ramp?

 

Quickly and aggressively

Backward and rapidly

Forward and slowly

Sideways and cautiously

 

Correct Answer: C. Forward and slowly

 

14. What is the suggested purpose of minimizing reversing to a segregated, controlled area?

 

To reduce fuel consumption

To improve roller performance

To increase operator visibility

To minimize risks to pedestrians and workers

 

Correct Answer: D. To minimize risks to pedestrians and workers

 

15. Why is the roller at risk of overturning when being driven along a slope that is too steep?

 

Insufficient roller weight

Center of gravity exceeding the width of the drum

Excessive roller speed

Lack of proper roller maintenance

 

Correct Answer: B. Center of gravity exceeding the width of the drum
