9. What is the purpose of the safety pin? Give ONE answer
A To make sure the bucket does not rotate
B To make sure the latch system correctly unclasps
C To make sure the latch system does not unclasp
D To make sure the operator is secured to the boom
Correct Answer: C To make sure the latch system does not unclasp
Explanation: The safety pin is used to make sure the latch system does not unclasp.
10. There are a select number of approved lifting points to which accessories can be attached. Which THREE of the following are possible consequences of not following this guidance? Give THREE answers
A A load falls
B Somebody is injured by lifting equipment
C The manufacturer sues
D The vehicle becomes imbalanced
Correct Answer: A A load falls, B Somebody is injured by lifting equipment, D The vehicle becomes imbalanced
Explanation: It is important to follow lifting point recommendations, as these will help avoid injury and accident.
11. Operators should consult the excavator's Operator's Manual - but which THREE of the following parties may also need to use it? Give THREE answers
A Maintenance staff
B Pedestrians
C Supervisors
D Transporter drivers
Correct Answer: A Maintenance staff, C Supervisors, D Transporter drivers
Explanation: Parties involved in maintaining, transporting, and supervising use of the vehicle may additionally need to consult the manual.
12. Which TWO of the following reasons describe why an oversized bucket is inappropriate for excavations done to specification? Give TWO answers
A Extra spoil will be removed
B It will be more expensive
C It will damage underground services
D More backfilling is required
Correct Answer: A Extra spoil will be removed, D More backfilling is required
Explanation: Using an oversized bucket will slow down the excavation, as excess spoil will be removed and require additional backfilling.
13. What must the operator ensure before they leave the cab? Give TWO answers
A That the bucket or attachment is lowered
B That the bucket or attachment is raised
C That the engine is switched off
D That the engine remains on
Correct Answer: A That the bucket or attachment is lowered, C That the engine is switched off
Explanation: To ensure machine stability and avoid the risk of falling equipment, make sure the bucket or attachment is lowered and the engine is off before exiting the cab.
14. You notice that the excavator engine is overheating during a lifting operation. Why should you NOT remove the radiator/expansion tank cap? Give ONE answer
A Corrosive liquid may spray out and cause irritation
B Hot liquid may spray out and cause burns
C Hot liquid may spray out and damage the engine
