Change Engine Oil

Service Interval: After the first 5 hours

Every 100 hours (May need more often under severe conditions.)

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

2.Drain oil while engine is warm from operation.

3.The oil drain valve is located on the left side of the engine.

Place the pan under the machine to catch the oil. Install the clear plastic tube, located in the literature pack, onto the oil drain valve. Loosen the oil drain valve and allow the oil to drain.

Tighten the oil drain valve and remove and retain the clear plastic tube.

4.Replace the oil filter per the Engine Owner’s Manual. Clean around the oil filter and carefully remove the filter by unscrewing it. Make sure no oil drains onto the belt drive or clutch through the holes in the engine deck. Before the new filter is installed, apply a thin coating of Exmark 4–Cycle Premium Engine Oil on the surface of the rubber seal. Turn filter clockwise until rubber seal contacts the filter adapter, then tighten filter an additional 2/3 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 the Check Engine Oil Level section. 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, and remove key. 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.
