Changing the Hydraulic
System Filter and Oil
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.
Removing the Hydraulic System Filters
1. Stop engine, wait for all moving parts to stop, and
allow engine to cool.
