with a diesel specification of “CD ” or oils of
a higher quality than specified. In addition,
do not use oils labeled “ENERGY CONSERV-
ING II ” or higher.

WARNING
EWB02380Never run the engine in an enclosed area when
purging the spark arrester, otherwise it could
cause injury to the eyes, burns, carbon monox-
ide poisoning, possibly leading to death, and
start a fire.
Always let the exhaust system cool prior to
touching exhaust components.
Always wear eye protection, and make sure
no one is behind the ATV.
Make sure there are no combustible materi-
als in the area.EBU23931V-belt case drain plug After riding in water deep enough to allow it to en-
