Changing the Engine Oil

Change the engine oil after the first 2 operating hours, after
every 25 operating hours, and at the end of the
snowthrowing season. If possible, run the engine just
before changing the oil because warm oil flows better and
carries more contaminants.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug and ensure that
the wire does not contact the spark plug (Fig. 18).
3. Clean the area around the oil drain plug (Fig. 33).

Replacing the Spark Plug

Use a Champion RJ-19LM or equivalent spark plug. Install
a new plug after every 100 operating hours.
1. Stop the engine and wait for all moving parts to stop.
2. Clean any debris from around the base of the spark
plug.
3. Disconnect the wire from the spark plug (Fig. 18).
4. Remove the spark plug.
5. Examine the spark plug and replace it if it is cracked,
fouled, dirty, or if the electrodes are worn.
Important Do not clean the electrodes because grit
could enter the cylinder and damage the engine.
6. Set the gap between the electrodes on the spark plug at
0.030 in. (0.76 mm) as shown in Figure 34.
