6. Slowly pour approximately 80% of the specified oil
into the filler cap (Fig. 33). Refer to Servicing the
Engine Oil, page 29.
7. Check the oil level; refer to Checking the Oil Level,
page 29.
8. Slowly add additional oil to bring it to the full mark.
Changing the Oil Filter
Replace the oil filter every 200 hours or every other oil
change.
Note: Change oil filter more frequently when operating
conditions are extremely dusty or sandy.
1. Drain the oil from the engine; refer to Changing the
Engine Oil, page 29.
2. Remove the old filter (Fig. 35).
3. Apply a thin coat of new oil to the rubber gasket on
the replacement filter (Fig. 35).

5. Fill the crankcase with the proper type of new oil;
refer to Changing the Engine Oil, page 29.
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 (.75 mm)
Removing the Spark Plug
1. Disengage the power take off (PTO), set the parking
brake, and turn the ignition key to off. Remove the
key.
2. Pull the wire(s) off the spark plug(s) (Fig. 36). Now
clean around the spark plug(s) to prevent dirt from
falling into the engine and potentially causing damage.
3. Remove the spark plug(s).

Checking the Spark Plug
1. Look at the center of the spark plug(s) (Fig. 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
(Fig. 37). Bend the side electrode (Fig. 37) if the gap is
not correct.
