CHECK / CHANGE AIR FILTER

Refer to the engine owners manual for specific air filter service procedures.

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 500 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 oil reservoir.

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.
