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.

CAUTION

Raising the mower deck for service or maintenance relying solely on mechanical or hydraulic jacks could be dangerous. The mechanical or hydraulic jacks may not be enough support or may malfunction allowing the unit to fall, which could cause injury.

Do Not rely solely on mechanical or hydraulic jacks for support. Use adequate jack stands or equivalent support.

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

WARNING

Engine must be running and drive wheels must be turning so adjustments can be performed. Contact with moving parts or hot surfaces may cause personal injury.

Keep fingers, hands, and clothing clear of rotating components and hot surfaces.

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.

Note: Do Not change the 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 contaminants into the system.

Check Spark Arrester (if equipped)

Service Interval: Every 50 hours

WARNING

Hot exhaust system components may ignite gasoline vapors even after the engine is stopped. Hot particles exhausted during engine operation may ignite flammable materials. Fire may result in personal injury or property damage.

Do Not refuel or run engine unless spark arrester is installed.

1.Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.

2.Wait for muffler to cool.
