7.3 Propeller
Before each flight the propeller should be inspected for nicks. If found, they should be repaired as
soon as possible as per manufacturer’s instructions.
7.4 Oil
The oil capacity of the Rotax series of engines is 3 litres.
The recommended oil to be used in the Rotax series of engines is Brand name motorcycle oil with
gear lubrication additive. Use oil with API classification SF or SG. Change oil and oil filter every
25 hrs. as per manufacturer’s instructions.
Refer to Rotax Maintenance Manual included for more detailed information.
7.5 Fuel
7.5.1. Fuel grades
Use unleaded fuel as per Rotax operator’s manual. Avoid if possible use of Avgas 100 LL
7.5.2. Filling Fuel Tanks
Observe all required precautions for handling gasoline. Each fuel tank holds a maximum of 12 US
gallons. Fill the tanks to the bottom of the filler neck to obtain the standard plus reserve quantity.
Fuel should be distributed equally between each side.
7.5.3. Draining Fuel Strainer, sumps and lines
The fuel system sumps and strainer should be drained daily prior to the first flight and after re-
fuelling to avoid the accumulation of contaminants such as water or sediment. Each fuel tank is
equipped with an individual quick drain located at the lower inboard rear corner of the tank. The
fuel strainer (galcolator) is equipped with a quick drain located on the lower front left corner of the
firewall. Each of the fuel tank sumps should be drained first. Then the fuel strainer should be
drained twice, once with the fuel selector valve on each tank. Each time fuel is drained sufficient
fuel should be allowed to flow to ensure removal of contaminants. This fuel should be collected in a
suitable container, examined for contaminants, and discarded.
7.5.4. Draining fuel system
The bulk of the fuel may be drained by opening the individual drain on each tank. The remaining
fuel may be drained through the gascolator. Any individual tank may be drained by closing the
selector valve and then draining the desired tank.
CAUTION!
When draining any amount of fuel care should be taken to ensure that no fire hazard exists
before starting the engine. Each quick drain should be checked after closing to make sure that it
has closed completely and is not leaking.
CAUTION!
Ensure that no fuel accidentally spills on Lexan windows or windshield. Fuel on Lexan will
cause the Lexan to discolor or crack.
