Periodic Maintenance Procedures

•Clean the spark plug, preferably in a sandblasting device, and then clean off any abrasive particles. The plug may also be cleaned using a high-flash point solvent and a wire brush or other suitable tool.

If the spark plug center electrode [A] and/or side electrode

[B]are corrected or damaged, or if the insulator [C] is cracked, replace the plug. Use the standard spark plug

•or its equivalent.

Measure the gaps [D] with a wire-type thickness gauge. If the gap is incorrect, carefully bend the side electrode with a tool to obtain the correct gap.

Spark Plug Gap: 0.7 ~ 0.8 mm (0.028 ~ 0.031 in.)

•Insert the spark plug vertically into the plug hole with the spark plug installed in the plug wrench [A].
