a) Oil level –Open the cover of the inspection hole on the engine cowling and unscrew the cap of the oil
tank. Manually turn the propeller few times in its rotating direction to push the oil from the engine into
the oil tank. Stop turning the propeller when you hear the „bubbling sound“ signalizing that only air
starts flowing from the engine into the oil tank. Check the oil level with the dipstick in the oil tank and
refill up to the maximum level if needed. Pay attention not to stain surrounding engine parts or its
compartment by oil, otherwise remove oil spots properly. Cover the oil tank with the cap. Install the
cover of inspection hole and secure by screws. Keep the oil level within the range marked on the
dipstick. Always use the same type of the oil which is already used in the engine. Cover the oil tank with
the cap. Never open the oil tank when the oil is hot!
b) Coolant level – Remove the upper cowling of the engine. The engine must always be cool when
checking the coolant amount. Do not open the expansion tank when the coolant is hot! Loosen the cap
of the expansion tank and check the coolant level. The maximum level allowance is about 2 cm below
the rim of the expansion tank. If the level is low, refill appropriate amount of the coolant. Cover the
engine by the upper cowling and fix it by screws. Keep the coolant level in the overflow bottle within the
marked range „MIN-MAX“.
