4.5 SPARK PLUG(S)
Reset the spark plug(s) gap or replace the spark plug(s) as neces-
sary. See the Service Schedule section for maintenance require-
ments.
1. Clean the area around the base of the spark plug(s) to keep
dirt and debris out of the engine.
2. Remove the spark plug(s) and check the condition. Replace
the spark plug(s) if worn or if reuse is questionable. See the
Service Schedule section for recommended inspection. Clean

mm (0.040 inch) for 15kW by carefully bending the ground
electrode (Figure 4.8).
