Servicing the Engine Oil

Checking the Oil Level

Service Interval: Before each use or daily

1.Park the machine on a level surface, disengage the blade control switch, stop the engine, engage parking brake, and remove the key.

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.Pull and remove the oil fill cap/dipstick; wipe oil off. Reinsert the dipstick and push firmly into place (Figure 20).

5.Remove the dipstick and check the oil level.

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

6.If the level is low, add oil of the proper type, up to the “F” mark on the dipstick. Always check the level with the dipstick before adding more oil.

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 “L” mark or over the “F” 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 neutral position and engage parking brake.
