5. Add the specified amount of the recommended
oil; refer to Changing and Draining the Oil in
Engine Maintenance, page 21.
6. Start the engine and check the filter for leaks.
7. Stop the engine and check the oil level; refer to
Checking the Oil Level in Engine Maintenance,
page 21. Add oil if necessary.
Servicing the Spark Plug
Check the spark plug after every 100 operating
hours. Make sure that the air gap between the
center and side electrodes is correct before
installing the spark plug. Use a 23 spark plug
wrench for removing and installing the spark
plug(s) and a gapping tool/feeler gauge to check
and adjust the air gap.
Replace the spark plug every 300 operating hours
or yearly.
Type: NGK BPR5ES or DENSO W16EPR-U (or
equivalent)
Air Gap: 0.028-0.031 inch (0.70-0.80 mm)
Removing the Spark Plug
1. Disengage the blade control switch, set the
parking brake, stop the engine, and remove
the key.
2. Pull the wire off of the spark plug (Figure 29).
Clean around the spark plug to prevent dirt
from falling into the engine and potentially
causing damage.

3. Remove the spark plug and sealing washer.
Checking the Spark Plug
1. Look at the center of the spark plug (Figure 30).
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 30). Bend the side electrode
(Figure 30) if the gap is not correct.

Installing the Spark Plug
1. Make sure that the air gap is set correctly.
2. Install the spark plug by hand to avoid
cross-threading. Tighten new spark plugs
1/2 turn with a spark plug wrench. When
reinstalling the spark plug previously removed,
only tighten 1/8-1/4 turn.
3. Push the wire onto the spark plug (Figure 29).
