When it is advisable to check or replace the spark plug

In general, the spark plug is checked during servicing and before extended periods of use. It may be useful to plan a check even after long periods of inactivity or in case of severe usage conditions. Evaluating the condition of the removed spark plug can also provide useful indications for diagnosis, to be interpreted according to the manufacturer's guidelines.
