HYDROSTATIC TRANSMISSION OIL & FILTER SERVICE

If transmission is to be serviced, proper air purging procedures must be followed, or damage will occur. Proceed as follows:

1.Remove oil filter from chassis, allowing oil to drain into container. Clean impurities from inside of reservoir, if necessary.

2.Install new oil filter to chassis. Use only genuine Dixon replacement oil filter.

3.Put fresh oil in reservoir. Fill reservoir to the full mark.

4.Remove two oil return hoses from top of oil reservoir and direct these hoses into a container for oil draining.

5.Depress by-pass valve on both hydros.

6.Start engine and move throttle to mid-range setting.

7.Release parking brake.

8.Dirty oil, filled with air bubbles, will start to drain from oil return hoses into container. When oil flowing from hoses is clear and contains no bubbles, stop the engine.

9.Reattach oil return hoses to top of reservoir.

10.Release by-pass valve on both hydros.

11.Add sufficient oil to reservoir to return oil level to the full mark.
