Servicing The Spark Plug - Toro 72211 Operator's Manual

Cleaning the Foam Element
1. Wash the foam element in liquid soap and warm
water (Figure 34 ). When the element is clean, rinse
it thoroughly.
2. Dry the element by squeezing it in a clean cloth (do
not wring). Allow the element to air dry.
Important: Replace the foam element if it is
torn or worn.
Cleaning the Paper Element
1. Lightly tap the element on a flat surface to remove
dust and dirt (Figure 35 ).
2. Inspect the element for tears, an oily film, and
damage to the rubber seal.
Important: Never clean the paper element
with pressurized air or liquids, such as solvent,
gas, or kerosene. Replace the paper element if
it is damaged or cannot be cleaned thoroughly.

Installing the Foam and Paper
Elements
Important: To prevent engine damage, always
operate the engine with the complete foam and
paper air cleaner assembly installed.
1. Carefully slide the foam element into the paper air
cleaner element (Figure 34 ).
2. Place the air cleaner assembly onto the air cleaner
base and install the wing nut (Figure 34 ).
3. Install the air cleaner cover and latch it (Figure 34 ).

Servicing the Spark Plug

Check the spark plug(s) after every 100 operating
hours. Make sure the air gap between the center and

side electrodes is correct before installing the spark
plug. Use a spark plug wrench for removing and
installing the spark plug(s) and a gapping tool/feeler
gauge to check and adjust the air gap. Install a new
spark plug(s) if necessary.
Type: Champion RCJ8Y (or equivalent)
Air Gap: 0.030 inch (0.75 mm)
Removing the Spark Plug(s)
1. Disengage the PTO and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Pull the wire(s) off of the spark plug(s) (Figure 36 ).
Clean around the spark plug(s) to prevent dirt
from falling into the engine and potentially causing
damage.
4. Remove the spark plug(s) and metal washer.

Checking the Spark Plug
1. Look at the center of the spark plug(s) (Figure 37 ).
If you see light brown or gray on the insulator, the
engine is operating properly. A black coating on
the insulator usually means the air cleaner is dirty.
Important: Never clean the spark plug(s).
Always replace the spark plug(s) when it has a
black coating, worn electrodes, an oily film,
or cracks.
2. Check the gap between the center and side
electrodes (Figure 37 ). Bend the side electrode
(Figure 37 ) if the gap is not correct.
