Hydraulic System Maintenance (Cont.)
Changing the Hydraulic System Filters and Fluid
Service Interval: After the rst 75 hours of use: Change the hydraulic system lters and uid
Every 250 hours (after the initial change): Change the hydraulic-system lters and uid when
using Mobil 1 15W-50 uid (change the uid more often under severe conditions).
Every 500 hours (after the initial change): Change the hydraulic system lters and uid when
using Mobil 1 15W-50 uid (change the uid more often under severe conditions).
Change the oil and the lters at the same time. Do not reuse the oil. Purge any air from the system after installing
the new lters and add oil see “Purging Procedure,” chapter 7, page 7-8. Repeat the purging procedure until
the oil remains at the FULL COLD line in the reservoir after purging.
NOTE: Failure to properly perform this procedure can result in irreparable damage to the hydrostatic
drive system.
