Engine lubrication system
Rotax 912
is a four-stroke engine, equipped with a dry sump and lubricated centrally with use of its
own oil pump. All the oil needed is located inside an outer canister. When the engine is running, the
oil cools itself passing through a radiator, located on the left-hand side of the bottom engine cover.
Oil quantity can be checked visually with a oil level bar. Make sure the oil quantity is sufficient limits
at all times.
CAUTION!
Oil temperature, pressure and quality is strictly defined an must not, under any cir-
cumstances, vary from its safe values.
