Changing The Engine Oil; Servicing The Spark Plug - Toro 22195 Operator's Manual

9. Clean the foam element in warm, soapy water or in a
nonflammable solvent.
Note: Do not use gasoline to clean the foam element
because it could create a risk of fire or explosion.
10. Rinse and dry the foam element thoroughly.
11. Dip the foam element in clean engine oil, then squeeze
out the excess oil.
Note: Excess oil in the foam element restricts the air
flow through the element and may reach the paper
filter and clog it.
12. Wipe dirt from the base and the cover with a moist rag.
Note: Be careful to prevent dirt and debris from
entering the air duct leading to the carburetor.
13. Install the air cleaner elements and ensure that they are
properly positioned.

Note: Warm oil flows better and carries more
contaminants.
WARNING
Oil may be hot after engine has been run, and
contact with hot oil can cause severe personal
injury.
Avoid contacting the hot engine oil when you
drain it.
2. Stop the engine and wait for all moving parts to stop.
3. Disconnect the wire from the spark plug.
4. Place a suitable drain pan under the dipstick/oil drain.
5. Clean around the dipstick.
6. Remove the dipstick by rotating the cap
counterclockwise and pulling it out.
7. Raise the left side of the mower to drain the oil from
the dipstick fill tube into the drain pan.
8. After draining the oil, return the mower to its operating
position.
9. Fill the crankcase to the upper limit mark on the
dipstick with fresh oil. Refer to the Filling the
Crankcase with Oil.

Servicing the Spark Plug

Service Interval: Every 100 hours—Inspect, clean, and

plug or equivalent.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug.
3. Clean around the spark plug.
4. Remove the spark plug from the cylinder head.
Important: Replace a cracked, fouled, or dirty
spark plug. Do not clean the electrodes because
grit entering the cylinder can damage the engine.
5. Set the gap on the plug to 0.030 in. (0.76 mm)
(Figure 24).
1. Center electrode insulator
2. Side electrode
3. Air gap (not to scale)
6. Carefully install the spark plug by hand (to avoid cross
threading) until it is hand tight.
7. Tighten the spark plug an additional 1/2 turn if it is
new; otherwise, tighten it an additional 1/8 to 1/4 turn.
