the plug wrench to protect the plug thread.

NOTE:

·In the case of screwing in a new spark plug, tighten it by

an additional 1/2 screw turn after the plug reaches and pushes

on the O-ring, while in the case of a used spark plug, an

additional 1/2~1/4 screw turn is necessary.

CAUTION:

· Make sure the spark plug is properly tightened.

Improper tightening may cause the engine to be overheated

or damaged. Never use spark plugs with an incorrect thermal

value range.
