CAUTION: IMMEDIATELY CLEAN OFF ALL ENGINE OIL THAT FALLS ON THE PAINTED
_______
SURFACES AND RUBBER PARTS OF THE AIRPLANE. THE SPECIFIED OIL
FOR THIS OIL SYSTEM WILL CAUSE DAMAGE TO THE PAINTED SURFACES
AND SOME TYPES OF RUBBER AND MUST NOT BE PERMITTED TO TOUCH
THESE PARTS OF THE ENGINE.
USE VERY CLEAN CONTAINERS AND EQUIPMENT. OIL CONTAMINATION BY SMALL QUANTITIES OF SOME ALKALINE CLEANERS CAN CAUSE A FAILURE OF THE SYNTHETIC OIL.
DO NOT PUT THE OIL THAT IS DRAINED FROM THE ENGINE BACK INTO THE ENGINE.
