15. Slowly pour approximately 80% of the specified oil
into the filler tube (Figure 30).
16. Install the oil fill cap/dipstick and push firmly into
place (Figure 30).
17. Check the oil level (Figure 30); refer to Checking
the Oil Level.
18. Slowly add additional oil to bring it to the full mark.
19. Install the oil fill cap/dipstick and push firmly into

Servicing the Spark Plug
Service Interval: Every 200 hours—Check spark plug
condition and gap.
Every 500 hours—Replace the spark
plug.
The spark plug is RFI compliant. Equivalent alternate
brand plugs can also be used. Spark plug replacement is
recommended at 500 hours.
Type: Champion XC12YC (or equivalent)
Air Gap: 0.030 inch (0.76 mm)
Removing the Spark Plug
1. Disengage the blade control switch, move the
motion controls outward to the park position, stop
the engine, and remove the key.
2. Pull the wire off of the spark plug (Figure 34). Clean
around the spark plug to prevent dirt from falling
into the engine and potentially causing damage.
Note: Due to the deep recess around the spark
plug, blowing out the cavity with compressed air
is usually the most effective method for cleaning.
The spark plug is most accessible when the blower
housing is removed for cleaning.
3. Remove the spark plug and metal washer.

Checking the Spark Plug
1. Look at the center of the spark plug (Figure 35).
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. Always
replace the spark plug when it has a black
coating, worn electrodes, an oily film, or cracks.
2. Check the gap between the center and side electrodes
(Figure 35). Bend the side electrode (Figure 35) if
the gap is not correct.

Installing the Spark Plug
1. Install the spark plug. Make sure that the air gap is
set correctly.
2. Tighten the spark plug to 30 ft-lb (41 N-m).
3. Push the wire onto the spark plug (Figure 34).
Cleaning the Blower Housing
To ensure proper cooling, make sure the grass screen,
cooling fins, and other external surfaces of the engine
are kept clean at all times.
