B) Relying solely on the rear view mirror

C) Implementing proper planning and communication

D) Accelerating the reversing speed

 

Correct Answer: C) Implementing proper planning and communication

 

9. What’s the primary reason for checking the umbilical cord when reaching the end of the run?

 

A) To minimize the roller’s weight for improved movement

B) To confirm the cord’s length for the next run

C) To prevent potential entrapment of the cord during turning

D) To enhance the roller’s traction for the next pass

 

Correct Answer: C) To prevent potential entrapment of the cord during turning

 

10. What hazards might arise when cleaning the cab glass of a dozer?

 

A) Risk of scratching the glass

B) Dangers related to working at height

C) Potential for increased visibility

D) None, as it’s a straightforward task

 

Correct Answer: B) Dangers related to working at height

 

11. What’s the purpose of referencing the winch manufacturer’s manual before winching work on dozers?

 

A) To bypass safety procedures for faster task completion

B) To ensure the winch’s functions are not optimized

C) To neglect any potential hazards related to the winching task

D) To adhere to proper planning and safety protocols

 

Correct Answer: D) To adhere to proper planning and safety protocols

 

12. How can the fuel efficiency of the dozer be improved?

 

A) By maintaining maximum engine speed

B) By running the machine inefficiently

C) By operating the machine efficiently without maximum engine speed

D) By using the highest gear in all situations

 

Correct Answer: C) By operating the machine efficiently without maximum engine speed

 

13. What is the primary purpose of providing a barrier or earth bund near the edge of an embankment in a work area?

 

A) To prevent the dozer from accidentally going over the edge

B) To signal the edge of the embankment for better visibility

C) To improve the aesthetics of the work area

D) To facilitate better access for other construction vehicles

 

Correct Answer: A) To prevent the dozer from accidentally going over the edge

 

14. How does slot dozing aid in working efficiency during earthmoving operations?

 

A) By maximizing material spillage from each side of the blade

B) By minimizing material spillage from each side of the blade

C) By reducing the material pushed on each pass

D) By decreasing overall operating speed

 

Correct Answer: B) By minimizing material spillage from each side of the blade

 

15. What should the operator ensure before taking any strain when pulling the stuck vehicle?
