Servicing The Spark Plugs - Toro 22321 Operator's Manual

Changing the Oil
1. Start the engine and let it run for five minutes. This
warms the oil so it drains better.
2. Park the traction unit so that the drain side is slightly
lower than the opposite side to ensure that the oil
drains completely.
3. Lower the loader arms, set the parking brake, stop
the engine, and remove the key.
Components will be hot if the traction unit has
been running. If you touch hot components you
may be burned.
Allow the traction unit to cool before performing
maintenance or touching components under
the hood.
4. Remove the drain plug (Figure 32).

Changing the Oil Filter

the Oil.

4. Pour new oil of the proper type through the center
hole of the filter. Stop pouring when the oil reaches
the bottom of the threads.
5. Allow a minute or two for the oil to be absorbed by
filter material, then pour off the excess oil.
6. Apply a thin coat of new oil to the rubber gasket
on the replacement filter.
7. Install the replacement oil filter to the filter adapter.
Turn the oil filter clockwise until the rubber gasket
contacts the filter adapter, then tighten the filter an
additional 1/2 turn.
8. Fill the crankcase with the proper type of new oil;
refer to Changing the Oil.
