2.Locate the two filters under the transmissions. Remove filter guards.

3.Carefully clean area around filters. It is important that no dirt or contamination enter hydraulic system.

6.Raise the rear of machine up and support with jack stands (or equivalent support) just high enough to allow drive wheels to turn freely.

7.Start engine and move throttle control ahead to 1/2 throttle position. Disengage parking brake.

A.With the bypass valve open and the engine running, slowly move the directional control in both forward and reverse (5 or 6 times).

B.With the bypass valve closed and the engine running, slowly move the directional control in both forward and reverse directions (5 to 6 times). Check the oil level, and add oil as required after stopping the engine.

C.It may be necessary to repeat steps A and B until all the air is completely purged from the system. When the transaxle operates at normal noise levels and moves smoothly forward and reverse at normal speeds, then the transaxle is considered purged.

Do Not change hydraulic system oil (except for what can be drained when changing filter), unless it is felt the oil has been contaminated or been extremely hot.

Changing oil unnecessarily could damage hydraulic system by introducing contaminates into the system.

Servicing the Spark Plug

Service Interval: Every 200 hours/Every 2 years (whichever comes first)

Every 500 hours—Replace the spark plug.
