Step
1 Check oil level and replenish as required.
NOTE:
2
Remove oil tank. Prior to oil check, turn the propeller by
hand in direction of engine rotation several times to pump
oil from the engine into the oil tank.
3 It is essential to build up compression in the combustion
chamber. Maintain the pressure for a few seconds to let the
pressure flow around the piston rings into the crankcase.
The speed of rotation is not important for the pressure
transfer into the crankcase.
4 This process is finished when air is returning back to the oil
tank and can be noticed by a murmur from the open oil
tank.
5 Install oil tank cap.
NOTE: The oil level should be in the upper half (bet-
ween the "50%" and the "max" mark) and
should never falls below the "min" mark. Prior to
long flights oil should be added so that the oil
level reaches the "max" mark.
Avoid oil levels exceeding the "max" mark, since excess oil could
be poured out through the venting system.
Difference between max.- and min.- mark = 0.45 litre (0.95 liq pt)
