Maintenance

Check for Loose Hardware

Service Interval: Before each use or daily

1.Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.

2.Visually inspect machine for any loose hardware or any other possible problem. Tighten hardware or correct the problem before operating.

Service Air Cleaner

Service Interval: Every 50 hours—Service the air cleaner. (May need more often under severe conditions. See the Engine manual for additional information.)

Every 600 hours— Replace the air cleaner elements. (May need more often under severe conditions. See the Engine manual for additional information.)

1.Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.

2.Loosen retaining clips and remove air cleaner compartment cover.

3.Remove paper element. Check the condition of the paper element. Replace if dirty, bent or damaged.

4.Check the condition of the inner element. Replace whenever it appears dirty, typically every other time the paper element is replaced. Clean the base around the inner element before removing, so dirt does not get into the engine.

5.Do Not wash or use pressurized air to clean paper element or inner element.

6.Reinstall elements. Position the cover so that the rubber dust ejector is pointing downward and secure with retaining clips.

2.Drain oil while engine is warm from operation.

3.The oil drain hose is located on right hand side of engine. Place pan under machine to catch oil. Remove plug from end of drain hose. Allow oil to drain and replace oil drain plug. Torque plug to 20-24 ft-lb.

4.Replace the oil filter every other oil change. Clean around oil filter and unscrew filter to remove. Before reinstalling new filter, apply a thin coating of oil on the surface of the rubber seal. Turn filter clockwise until rubber seal contacts the filter adapter then tighten filter an additional 1/2 to 3/4 turn.

5.Clean around oil fill cap and remove cap. Fill to specified capacity and replace cap.

6.Use oil recommended in engine owner’s manual. Do Not overfill. Start the engine and check for leaks. Stop engine and recheck oil level.

Check Hydraulic Oil Level

Service Interval: Every 40 hours

1.Stop engine and wait for all moving parts to stop. Engage parking brake.

2.Clean area around hydraulic reservoir cap and remove cap. Oil level should be to the top of the baffle inside the tank. If not, add oil. Use Exmark Premium Hydro oil. Replace hydraulic reservoir cap and tighten until snug. Do Not overtighten.

Note: The baffle is labeled “HOT” and “COLD”. The oil level varies with the temperature of the oil. The “HOT” level shows the level of oil when it is at 225°F (107°C). The “COLD” level shows the level of the oil when it is at 75°F (24°C). Fill to the appropriate level depending upon the temperature of the oil. For example: If the oil is about 150°F (65°C), fill to halfway between the “HOT” and “COLD” levels. If the oil is at room temperature (about 75°F (24°C)), fill only to the “COLD” level.
