Fuel level is checked using the dip stick
which has to be inserted diagonally from
the fuel filler port. Note that the upper
end of the stick shows 3 narrow rings as
markings. Remove dip stick from tank
and read level. Markings are available
per 10 litres. Wipe and return dip stick to
its holder.
NOTE
Do not fill to the absolute maximum in order to allow for thermal expansion of
the fuel. Fill only to a gap of around 10mm under the filler cap neck.

Checking of Engine Oil Level
Before attempting to check the engine oil level double check that both LANE switches are
switched off. The oil level is measured with the aircraft in a level attitude and should be
between the marks on the dipstick.
Open oil tank access cover, remove oil reservoir cap and dipstick. Turn the engine by the
propeller in the correct sense of rotation until you clearly hear the oil gurgle in the tank over
several rotations. The oil is pushed into the tank when pressure is felt whilst turning the
prop, meaning that the crankcase pressure is at its maximum.
Insert cleaned dipstick for measurement. Fill up oil according to the engine manufacturer’s
specification when required. After completion make sure the dip stick is in place and the
reservoir cap is back on securely. Install access cover.
CAUTION
Never attempt to turn the engine against its sense of rotation as this may lead
to expensive hydraulic tappet damage.
