change.
Note: Change the oil filter more frequently when
operating conditions are extremely dusty or sandy.
1. Drain the oil from the engine; refer to Changing the
Oil, page 34.
2. Remove the old filter and wipe the filter adapter
(Fig. 47) gasket surface.
3. Pour new oil of the proper type in through the center

additional 1/2 turn (Fig. 47).

refer to Changing the Oil, page 34.
Servicing the Spark Plug
Check the spark plug(s) after every 200 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 RC12YC (or equivalent)
Air Gap: 0.030 inch (0.76 mm)
Removing the Spark Plug(s)
7. Set the parking brake, stop the engine, remove the key,
and wait for all moving parts to stop before leaving the
operating position.
8. Pull the wire(s) off the spark plug(s) (Fig. 48). Now
clean around the spark plug(s) to prevent dirt from
falling into the engine and potentially causing damage.
9. Remove the spark plug(s) and metal washer.
