Changing the Hydraulic System Filter and Oil

Service Interval: After the first 50 hours

Every 400 hours thereafter.

The filter and oil are changed at the same time. Do Not reuse oil. Once the new filter is installed and oil is added any air in the system must be purged.

The bleeding process is repeated until the oil remains at the FULL COLD line in the reservoir after purging.

Failure to properly perform this procedure can result in irreparable damage to the transaxle drive system.

1.Stop engine, wait for all moving parts to stop, and allow engine to cool. Remove the key and engage the parking brake.

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