Generally, the engines are planned to run on a gasoline-oil mix-
ture of 50:1. This mixture supplies proper engine lubrication.
If the engine has been assembled for oil injection lubrication,
the carburetors are supplied with pure gasoline.
The integrated oil pump will deliver the exact amount of oil re-
quired for engine lubrication.
Make sure that adequate amount of oil is in the oil tank before
putting engine into service.
NOTE
For fuel refer to section 2.3.
Generally the engines are designed to run on a gasoline-oil
mixture of 50:1 unless equipped with optional ROTAX® oil in-
jection system. For preparation of fuel-oil mixture refer to sec-
tion 2.3.
The oil pump driven by the crankshaft via cross shaft feeds the
engine with fresh oil. The oil pump is a piston type pump with
metering system. Via diffuser jets in the intake cover respec-
tively intake socket each cylinder is supplied with exactly pro-
portioned quantity of Super two-stroke oil. The oil quantity is
defined by the engine rpm and the oil pump lever position. This
lever is actuated via a Bowden cable connected to the throttle
cable. The oil comes to the pump from an oil tank by gravity.
