2. Lubricate the new filter base with a few drops of transmission oil. Fill the filter half full of oil. 1. Locate the transmission oil filter (A, Figure 17). 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. IMPORTANTNOTE: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. A Figure 17. Change Hydraulic Oil Filter A. Hydraulic Oil Filter Maintenance 29 Regular Maintenance Maintenance 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. Doing so may induce air into the cooling system and may cause overheating. 1. Check the coolant level only at the overflow reservoir (A, Figure 18). The coolant level should be between the “H” and “L” marks. 2. If the coolant level is insufficient, remove the cap (B) from the reservoir and add coolant to the “H” mark. 3. Reinstall the cap. NOTE: Proper coolant mix is a 50/50 mixture of ethylene glycol and distilled water. See engine owners manual for engine coolant specifications. CHANGE ENGINE COOLANT See engine owners manual for specific engine coolant change procedures. CLEAN RADIATOR & SCREEN Clean the radiator and screen before each use, or as required (depending on conditions) to allow proper air-flow through the radiator. 1. To remove the radiator screen, lift the seat. 2. Release radiator screen latch (C), slide towards the left hand side of the machine. Lift screen enough to clear radiator cap and slide out the front. 3. Flush the screen with water or blow clean with air. Flush the radiator core with water or blow clean with air. See engine owners manual for proper radiator cleaning procedures. 4. To reinstall the radiator screen, reverse removal process. WARNING PRESSURIZED SYSTEM Hot coolant can cause serious burns. Never open the radiator cap. Wait until the engine is cool before checking the coolant level or removing the reservoir cap. D C A B Figure 18. Radiator, Screen & Overflow Bottle A.

Grease: • front caster wheel axles & yokes • deck lift pivot blocks • mower deck spindles • mower deck idler arm Use grease fittings when present. Disassemble parts to apply grease to moving parts when grease fittings are not installed. Not all greases are compatible. Ferris Red Grease (p/n 5022285) is recommended, automotive-type high-temperature, lithium grease may be used when this is not available. Oil: • control handle pivots • seat plate pivots • deck lift pivots • discharge chute hinge Generally, all moving metal parts should be oiled where contact is made with other parts. Keep oil and grease off belts and pulleys. Remember to wipe fittings and surfaces clean both before and after lubrication. Figure 19. Deck Lubrication Figure 20.

Cleaning the Battery and Cables - Air Cooled Models. 1. Remove the hydraulic oil reservoir mounting hardware (C, Figure 24) and move the reservoir (D) forward to expose the battery. 2. Disconnect the cables from the battery, negative (black) cable first (B). 3. Clean the battery terminals and cable ends with a wire brush until shiny. 4. Reinstall the battery and reattach the battery cables, positive (red) cable first (A). 5. Coat the cable ends and battery terminals with petroleum jelly or non-conducting grease. 6. Reposition the oil reservoir and secure in place with the hardware previously removed. WARNING Be careful when handling the battery. Avoid spilling electrolyte. Keep flames and sparks away from the battery. When removing or installing battery cables, disconnect the negative cable FIRST and reconnect it LAST. If not done in this order, the positive terminal can be shorted to the frame by a tool. Cleaning the Battery and Cables - Liquid Cooled Models. 1. Raise the seat plate to expose the battery. 2. Disconnect the cables from the battery, negative (black) cable first (B). 3. Clean the battery terminals and cable ends with a wire brush until shiny. 4.
