then tighten the filter an additional 1/2 turn

12. Remove the oil fill cap and slowly pour
approximately 80% of the specified amount of
oil in through the valve cover.
13. Check the oil level; refer to Checking the Oil
Level, Operation, page 17.
14. Slowly add additional oil to bring the level to
the F (full) mark on the dipstick.
15. Replace the fill cap.
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 Premium Gold 2071, RC12YC,
or equivalent. Air Gap: 0.030 inch (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 (Figure 23).

3. Clean around the spark plugs.
4. Remove both spark plugs and metal washers.
Checking the Spark Plugs
1. Look at the center of both spark plugs
(Figure 24). 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 plugs.
Always replace the spark plugs when they
have a black coating, worn electrodes, an
oily film, or cracks.

2. Check the gap between the center and side
electrodes (Figure 24).
3. Bend the side electrode (Figure 24) if the gap
is not correct.
Installing the Spark Plugs
1. Thread the spark plugs into the spark plug
holes.
2. Tighten the spark plugs to 20 ft-lb (27 N
⋅
m).
3. Push the wires onto the spark plugs (Figure 23).

Never install a dirty filter.
1. Lower the loader arms, stop the engine, and
remove the key.
2. Shut off the fuel valve on the bottom of the
fuel tank (Figure 26).
3. Clamp the fuel line between the fuel tank and
the fuel filter to block the fuel flow.
4. Squeeze the ends of the hose clamps together
and slide them away from the filter (Figure 25).
