CHECK HYDRAULIC OIL LEVEL
NOTE: Do not open the hydraulic oil reservoir unless
oil is being added.
1. Visually check that the hydraulic oil level is filled to
the recess area (A, Figure 16) of the hydraulic oil
reservoir.
2. If necessary, remove the reservoir cap (B)
and add either Mobil 1™, 15W-50 synthetic oil
or Castrol Syntec™ 5W-50 oil. DO NOT use
conventional oils. Make sure area around the filler
neck is free of dust, dirt, or other debris.
HYDRAULIC OIL FILTER CHANGE
Change Interval: Every 250 Hours
Filter Part Number: 5021357
NOTE: Removing the oil filter from the filter base
will drain the oil reservoir. Have a suitable container
ready to catch any spilled oil. Ferris recommends this
be a dealer-only service item.
1. Locate the hydraulic oil filter (A, Figure 17) behind
the battery.
2. Fill the new filter with oil. Lubricate the new filter
seal with a few drops of oil.
3. Remove the oil filter and quickly thread the new
filter onto the filter base until the gasket makes
contact, then tighten 3/4 of a turn more.
4. Refill reservoir with fresh oil to replace any oil lost
during filter change.
5. Raise the rear of the unit and secure with
jackstands. Chock the front wheels to prevent the
unit from rolling. Run the unit for several minutes
to purge any air from the hydraulic system and
check the hydraulic oil level.
IMPORTANT NOTE: Use caution after changing
the filter; air in the hydraulic system may affect the
responsiveness of the control levers. Repeat step 5
until the air is out of the system.
