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
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.

Check Engine Coolant Level
The engine coolant level and quality should be
checked before each use, when the engine is cool
and off.
The cooling system is a closed type. Never open
the radiator cap unless you are flushing the system.
Opening the radiator cap may induce air into the
cooling system and may cause overheating.
1. Open the hood to gain access to the overflow
bottle. (See Figure 23).
2. Check the coolant level only at the overflow
reservoir (A, Figure 23). The coolant level should
be at the LOW (COLD) mark.

WARNING
If engine is warm, DO NOT remove radiator
cap.
Escaping steam can cause burns.
Never remove the radiator cap or radiator
reservoir cap while the engine is hot or
running. Severe thermal burns or injury
can occur by escaping steam or hot
coolant.
• Do NOT touch hot radiator or open reservoir
when engine is running.
• Stop and allow engine to cool before removing
the radiator cap or the reservoir cap and before
changing or adding coolant.
