What is the minimum operating temperature for the HYEX using the coolant heater cold weather starting kit?

The minimum operating temperature for the HYEX using the coolant heater cold weather starting kit is -40°F. This is significant because the coolant heater is designed to ensure that the engine and hydraulic fluids remain at an optimal temperature for efficient starting and operation, preventing issues such as fluid thickening or cold starts that could cause excessive wear or difficulty in operating the excavator in harsh conditions. Operating at this low temperature allows the machine to function reliably in extreme cold, which is essential for maintaining productivity and performance in winter climates. The choice of -40°F ensures that even under severe temperature conditions, the hydraulic excavator can start and operate safely, making it suitable for a wide range of applications in cold weather environments.
