Maintenance

2.Make sure the engine is stopped, level, and is cool so the oil has had time to drain into the sump.

3.To keep dirt, grass clippings, etc., out of the engine, clean the area around the oil fill cap/dipstick before removing it.

4.Remove the oil fill cap/dipstick; wipe oil off. Reinsert the dipstick push into place, but Do Not screw it in (Figure 24).

5.Remove the dipstick and check the oil level.

The oil level should be up to, but not over, the “FULL” mark on the dipstick.

6.If the level is low, wipe off the area around the oil fill cap, remove cap and add oil to the “FULL” mark on the dipstick. Exmark 4-Cycle Premium Engine Oil is recommended; refer to the Engine Owner's manual for an acceptable alternative. Always check the level with the dipstick before adding more oil. Do Not overfill.

Note: To prevent extensive engine wear or damage, always maintain the proper oil level in the crankcase. Never operate the engine with the oil level below the “ADD” mark or over the “FULL” mark on the dipstick.

Changing the Oil and Filter

Service Interval: After the first 5 hours

Every 100 hours/Yearly (whichever comes first) thereafter.

Change the oil and filter while the engine is still warm. The oil will flow more freely and carry away more impurities. Make sure the engine is level when filling, checking, or changing the oil.

1.Start the engine and let it run until warm. This warms the oil so it drains better.

2.Disengage the blade control switch and move the motion controls outward to the parking brake position.

3.Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

4.Clean the area around the oil drain valve and on the machine frame.

5.Install the oil drain hose, located in the literature pack, onto the oil drain valve (Figure 25). Remove the oil fill cap/dipstick.
