4.1.5 Engine And Engine Compartment
The engine should be kept clean since dirty cooling fins and baffles can cause overheating of the
engine. Also, cleaning is essential to minimise any danger of fire and provide easy inspection of
components.
CAUTION
DO NOT hose engine. Electrical components may be damaged by moisture. Ensure electrical
components are protected against moisture. Caustic cleaning solutions should not be used.
Recommended cleaning procedure is lightly spray with degreasing fluid
– after sealing coils and
starter motor. WIPE clean with brush and cloth.
4.1.6 Propeller
Wash with soap and water, rinse with clean water and dry with cloth or chamois.
CAUTION
Do not use a wax based substance as this would make it almost impossible to refurbish the prop
if need at a later stage.
4.1.7 Wheels
The wheels should be washed periodically and examined for corrosion, cracks or dents in the wheel
halves or in the flanges or hubs. If defects are found, remove and repair in accordance with Section
0. Discard cracked wheel halves, flanges or hubs and install new parts.

Ground Handling
4.2.1 Towing
All Jabiru aircraft are relatively light and should always be moved by hand.
Moving the aircraft is accomplished by using the wing struts, prop hub or landing gear struts as push
points.
CAUTION
Do not use control surfaces to move the aircraft
– Damage to the control system may result
When pushing or moving the aircraft, take care that you do not jam your fingers under the rudder or
in the rudder hinge
– remember that it is connected to the Nose Wheel and will move whenever the
nose wheel direction changes.
The aircraft may also be moved by placing the propeller in the horizontal and then placing one hand
on the propeller on either side of the spinner. The aircraft can then be pulled forward.
WARNING
Never move the aircraft in this manner whilst the engine is hot as it may fire when the propeller is
moved and result in severe injury.
Always ensure that the Master and Ignitions are OFF.
Never approach the propeller when anyone is in the aircraft.
Always treat the propeller as LIVE! IT KILLS!
4.2.2 Jacking
Before jacking, ensure that it is as light as possible by removing luggage and any unnecessary fuel.
4.2.2.1 Jacking Main Gear
1.
Remove main gear spat on the side to be jacked or both spats if both wheels to be jacked.
2.
Where equipped, the fuel filler cap vent of the wing which is not being jacked may be blocked
using a vent cap. This is to prevent fuel leaking onto the wing while the aircraft is jacked.
