if running.
2. Move the inverter to a flat, level surface.

cover off the top of the housing (see Figure 20).

plastic spark plug boot handle directly away from
the engine.

Never apply any side load or move the spark plug
laterally when removing the spark plug. Applying a

If the spark plug fails any one of the
conditions listed above, replace the plug.

result in damage to the engine.

cylinder head. Hand-thread the spark plug until it
bottoms out.
b. Using the spark plug socket wrench provided,
turn the spark plug to ensure it is fully seated.
