4.4. LIFTING AND LEVELLING
When jacking the airplane the following procedure should be followed:
1
Put a stand (under a rib) under each wing to prevent the airplane from tilting.
2
Locate jacks under the nose landing gear ferrule and the other each side next to the cabin
walls, under the main landing gear box.
3
Apply wooden blocks.
4
Lift the airplane gradually to the required height. Lift the airplane, raising each jack evenly
at the same time and avoid swaying.
After lifting, the airplane should be leveled, so that the cabin wall edges are horizontal (see the
illustration).

5. CLEANING AND CARE
It is essential for the reliability of the airplane components to always keep them clean.
5.1. PAINTED EXTERNAL SURFACES
Prior to clean, take the following steps
1
Protect the wheels, especially the brake discs, covering them.
2
Put the cover on the pitot and static pressure sensors.
3
Mask off all holes and orifices.
Use clean water to remove all fine particles and then wash the surface with water adding mild
soap. Do not use detergents or soaps which are acid, alkaline or abrasive.
To remove spots of grease or oil, use a piece of cloth with degraseing solvent.
After use of degraseing solvent the surface should be re-waxed and polished.
To polish the painted surfaces, a soft cloth or chamois leather should be used.
Aged painted surfaces can be treated with automotive waxes or good quality polishing com-
pounds.
5.2. GLASS PANELS
The greatest care should be taken to avoid scratches when cleaning glass panels of plexiglass.
Never wipe the glass panels when dry. Rinse the panel with clean water or solution of mild soap
and then wipe with soft clean cloth, sponge or chamois leather.
To remove films of oil or grease, use tribasic sodium phosphate, well dissolved in water.
Sediments of grease or oil, if difficult to remove, should be cleaned with methanol, hexane, or
naphtha. Finally rinse with clean water avoiding excessive rubbing of the glass panel surface.
Caution! Do not use petrol, benzene, acetone, anti-icing compounds, or paint solvents,
because these substances soften the plexiglass, or may give rise to a network of fine cracks
5.3. PROPELLER
The propeller is to be cleaned in the same way as the painted surfaces.
5.4. ENGINE
The engine is to be cleaned as indicated in the Engine Maintenance Manual.
5.5. CABIN INTERIOR
The seats, carpets and upholstery have to be cleaned with a vacuum cleaner.
Do not use water to clean items of cloth or fabric.
Foam-based shampoos for general use on automotive upholstery may be applied, but the indica-
tions given on the packing should be strictly observed.
