3.6SPARK PLUG(S)
Reset the spark plug(s) gap or replace the spark plug(s) as necessary. See Section 4.1 for maintenance requirements.
1.Clean the area around the base of the spark plug(s) to keep dirt and debris out of the engine. Clean by scraping or washing using a wire brush and commercial solvent. Do not blast the spark plug(s) to clean.
2.Remove the spark plug(s) and check the condition. Replace the spark plug(s) if worn or if reuse is questionable. See Section 4.1 for recommended inspection.
3.Check the spark plug gap using a wire feeler gauge. Adjust the gap to 0.76 mm (0.030 inch) for 7 kW and 0.50 mm (0.020 inch) for 12 kW and 15 kW by carefully bending the ground electrode (Figure 3.7).
