Use the service hour meter to determine servicing intervals. Calendar intervals shown (daily, weekly, monthly, etc.) may be used instead of service hour meter intervals if they provide more convenient service schedules. Then, approximate the indicated service hour meter reading. Recommended service should always be performed at the interval that occurs first.Perform service on items at multiples of original requirement. For example, at Every 500 Hours or 3 Months, also service those items listed under Every 250 Service Hours or Monthly, Every 50 Service Hours or Weekly and Every 10 Service Hours or Daily.See the parts book included with your machine for part numbers of filters, belts, hoses, etc.See "Refill Capacities" and "Lubricant Viscosity Recommendations" charts for proper lubricants.When Required
