Changing the
Hydraulic-System Filters
and Fluid
Service Interval: After the first 75 hours—Change the
hydraulic-system filters and fluid.
Every 500 hours—After the initial change—change
the hydraulic-system filters and fluid when using Toro
™
HYPR-OIL
500 oil (change it more often under
severe conditions).
Every 250 hours—After the initial change—change
the hydraulic-system filters and fluid when using Mobil
1 15W50 fluid (change it more often under severe
conditions).
Change the filters and oil at the same time. Do not use the
oil again. Purge any air in the system after you install the new
filters and add oil. Refer to
(page
54).
Repeat the bleeding process until the oil remains at the F
C
line in the reservoir after purging. Failure to properly
OLD
perform this procedure can result in irreparable damage
to the transaxle drive system.
