Aircraft and systems on board
Engine lubrication system
Rotax 503 and 582 are two-stroke engines and are adequately lubricated by oil/fuel mixture. Proper
lubrication is ensured by adding 2% of syntetic of semi-syntetic oil into the fuel canister. However,
both Rotax 503 and 582 may optionally be equipped with an oil injection pump. Should your aircraft
be equipped with such a pump, refuel the aircraft with pure gasoline and add oil into a separate con-
tainer (see chapter “Limitations” for recommended oils)
Rotax 912 is a four-stroke engine, equipped with a dry carter and lubricated centrally with use of
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 sucient limits
at all times.
CAUTION! Oil temperature, pressure and quality is strictly dened an must not, under any cir-
cumstances, vary from its safe values.

Wheel brake system
Wheel brake system features seperate braking action for each of the main landing gear. Wheel
brakes are drum or disc, wire driven (old type) or hydraulic type (new type).
Wheel brake levers are operated by pressing the levers mouted on top of the rudder pedals.
Hydraulic brake uid used for hydraulic type brakes is DOT 3 or DOT 4.
To learn how to vent hydraulic brakes’ lining please see page 70 of this manual.
If the braking action on your aircraft is poor whilst the fully depressed wheel levers, please see page
71 of this manual to learn how to rectify this problem.
