Maintenance Intervals

NOTE

The maintenance interval charts outline required maintenance and inspection based on estimated vehicle engine hours / miles. Each table states the number of hours / miles that service is required on the vehicle. Some items or components may need to be serviced more often due to severe use, such as operation in water or under severe loads. When the vehicle goes beyond 400 hours, return to the 25 hours chart and start the interval process over.
