8.9 Cooling System
The water level in the overflow bottle should be checked prior to flight. The level should be between the
low and high mark on the overflow bottle. Water-cooling system capacity is 4.0 L. See maintenance
manual for further details.
Coolant Specification
Rotax specifies use of: 50% antifreeze concentrate with additives against corrosion and 50% pure water,
or use of an equivalent premixed coolant.
AirBorne has had satisfactory results using the brand Nulon Red which is silicate free and is a Mono
Ethylene Glycol product containing 1040 gm glycol per litre.
8.10 Tyre Inflation
The recommended tyre inflation pressures are 15 PSI for both the front and rear tyres. When checking
the tyre pressures the opportunity should be taken to examine the tyres for wear, cuts, bruises, slippage
and other defects.
8.11 Shock Struts
8.11.1
Rear Shocks
The rear shocks are pressurised to 580 psi using a schrader valve system. A special pump will be
necessary to repressurise the rear shocks to the correct setting. There should be no reason why the rear
shock would need to be reinflated, and if they do then a proper investigation of the cause should be
undertaken.
8.11.2
Front Shocks
The front shocks should be inflated to 50 psi for each reservoir. The top should be inflated first. Turn the
rebound damper fully clockwise, and then anticlockwise for twelve clicks.
