Servicing The Spark Plug; Greasing The Machine - Toro 30252 Operator's Manual

Servicing the Spark Plug

Check the spark plug after every 200 operating hours.
Ensure that 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 and a gapping tool/feeler gauge to check and adjust
the air gap. Install a new spark plug if necessary.
Type: Champion RC12YC or equivalent
Air Gap: 0.040 in. (1.02 mm)
Removing the Spark Plug
1. Disengage the blade control (PTO), set the parking
brake, stop the engine, and remove the key.
2. Pull the wire off of the spark plug (Fig. 32).
3. Clean around the spark plug to prevent dirt from
falling into the engine and potentially causing damage.
4. Remove the spark plug and metal washer.

Checking the Spark Plug
1. Look at the center of the spark plug (Fig. 33).
2. 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
Do not clean the spark plug. Always
replace the spark plug when it has a black coating, worn
electrodes, an oily film, or cracks.
3. Check the gap between the center and side electrodes
(Fig. 33).

4. Bend the side electrode (Fig. 33) if the gap is not
correct.
Installing the Spark Plug
1. Install the spark plug and metal washer.
2. Tighten the spark plug to 20 ft.-lb. (27 N m).
3. Push the wire onto the spark plug (Fig. 32).

Greasing the Machine

Grease the wheel and spindle bearing fittings every 8
operating hours and the transmission couplers every 200
operating hours. Grease more frequently when operating
conditions are extremely dusty or sandy.
Grease Type: General-purpose grease.
Adding Grease to a Fitting
1. Disengage the blade control (PTO), set the parking
brake, stop the engine, remove the key, and disconnect
the spark plug wire from the spark plug.
2. Clean the grease fitting with a rag.
3. Scrape any paint off the front of the fitting.
4. Connect a grease gun to the fitting.
5. Pump grease into the fitting until grease begins to ooze
out of the bearings.
6. Wipe up any excess grease.
