Description of Change: The relay switch for the heater (2) has been relocated into the breaker box (1) that is located behind the cab. The new location provides less vibration and lower ambient conditions for improved service life of the relay switch.

Adaptable To: Refer to Table 1 for a list of the machines and the effectivity of the changes that are listed above.
