Oil Draining
Drain oil from the oil tank by unscrewing the plug (wrench size No.17)
on the lower side of the oil tank. It is possible to drain oil from the
engine after unscrewing the plug in the lower part of the engine at the
hose of the return branch of oil flow. It is recommended to drain oil
immediately after engine test or after finishing the operation when oil
is sufficiently hot and better flows both from the engine and from the
tank. Clean the tank before filling it with new oil
– see Maintenance
Manual for ROTAX Engine.
Refilling Oil
Refill oil in the oil tank that is located on the firewall.
Venting of the Lubrication System
After short idling, stop engine and replenish oil to maximum mark on

tube during operation. At oil level inspect, do not exceed the
maximum mark.
