Question: On a large mining operation in Ontario, an operator observes the 'Transmission Temperature Warning' light illuminate steadily while climbing a steep ramp with a heavy load. What is the correct response?
Answer options:
- Shift to a lower gear and continue climbing, as the transmission will eventually cool. ✅ Downshift immediately, reduce engine RPM, and find a safe, level area to stop and allow the transmission to cool.
- Increase engine RPM to maximize hydraulic pump output and cool the system.
- Engage the parking brake and shut down the engine within 30 seconds.
Correct answer: Downshift immediately, reduce engine RPM, and find a safe, level area to stop and allow the transmission to cool.
Explanation: Overheating transmissions can lead to fluid breakdown and component damage. Ontario Regulation 213/91 (Construction Projects), Section 93 (Equipment operation – general), implies taking appropriate action for equipment defects. Reducing load and allowing cooling is critical. Immediate shutdown without proper cool-down can also cause damage.
