(Fig. 18).

the oil level is low, slowly pour only enough oil into the
filler tube to raise the level to the Full mark. Tighten the
dipstick.
6. Start and run the engine at idle for 30 seconds.
7. Shut the engine off and wait for 30 seconds. Check the

Changing and Draining the Oil
1. Start the engine and let it run five minutes. This warms
the oil so that it drains better.
2. Park the machine so that the drain side is slightly lower
than the opposite side to ensure that the oil drains
completely. Then disengage the PTO, set the parking
brake, stop the engine, and remove the ignition key.
3. Open the hood.
4. Place a pan below the oil dipstick/fill tube and remove
the drain plug (Fig. 19).
5. When the oil has drained completely, install the drain
plug.
Note: Dispose of the used oil at a certified recycling center.
6. Change the oil filter, if necessary; refer to Changing the
Oil Filter, page 21.
7. Slowly pour approximately 80% of the specified
amount of oil into the filler tube (Fig. 18). Check the oil
level; refer to Checking the Oil Level, page 20. Slowly
add additional oil to bring the level to the Full mark on
the dipstick.

(Fig. 20) gasket surface.
