3. Clean around the spark plug and remove it from the
cylinder head.
Important Replace a cracked, fouled, or dirty spark
plug. Do not clean the electrodes because grit entering the
cylinder could damage the engine.

Changing the Engine Oil
Change the oil after the first 5 operating hours and then
after every 50 hours or every season. Run the engine just
before changing the oil to warm the oil. Warm oil flows
better and carries more contaminants.
Note: Change the oil after every 25 hours when operating
under a heavy load or in high temperatures.
1. Disconnect the wire from the spark plug (Fig. 7).
2. Drain the gasoline from the fuel tank; refer to steps 3
and 4 of Emptying the Fuel Tank on page 15.
3. Remove the dipstick from oil fill tube and place a drain
pan next to the left side of the lawn mower.
