8.5 Refuelling
Have aircraft grounded before refuelling.
Be aware that most airfield refuelling
equipment is laid out for larger diameter
tank filler necks and high flow rates. To
avoid contamination, use a funnel with
strainer and/or filter when refuelling from
canisters. In order to top-off both tanks
allow flow levels to balance-out.
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.
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.
8.6 Checking of Engine Oil Level
Before attempting to check the engine oil level double check that both magnetos 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.
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.
