Regular Maintenance

Change Hydraulic Oil Filter

Change Interval: Every 250 Hours

Filter Part Number: 1719168

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 transmission oil filter (A, Figure 22). The transmission oil filter is located underneath the engine deck by the left rear tire of the machine.

2. Lubricate the new filter gasket with a few drops of

A

transmission oil. Fill the filter half full of oil.

 

3.Clean the area around the filter base and remove the filter. Do NOT drain the hydraulic system oil.

4. Thread the new filter onto the filter base until the

gasket makes contact, then tighten 3/4 of a turn

more.

 

5. Run the unit for several minutes and check the

 

transmission 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.
