NOTICE

Keep all parts clean from contaminants.

Contaminants may cause rapid wear and shortened component life.


Note: M.C.S. regulated engines are equipped with thermowells which allow specific temperature sensors to be removed with the engine running. A heat conductive compound is used to ensure that an accurate temperature reading is achieved by the temperature sensor when installed in a thermowell.
