Servicing the Spark Plugs

Check the spark plugs after every 200 operating
hours. Ensure that the air gap between the center and
side electrodes is correct before installing each spark
plug. Use a spark plug wrench for removing and
installing the spark plugs and a gapping tool/feeler
gauge to check and adjust the air gap. Install new
spark plugs if necessary.
Type: Champion RC12YC (or equivalent) Air Gap:
0.030 in. (0.76 mm)
Removing the Spark Plugs
1. Lower the loader arms, stop the engine, and
remove the key.
2. Pull the wires off of the spark plugs (Fig. 19).
3. Clean around the spark plugs to prevent dirt
from falling into the engine and potentially
causing damage.
4. Remove the spark plugs and metal washers.
