IMPORTANT! BEFORE FLYING C ECK ALWAYS EVERY PART OF
YOUR CRAFT, FROM ENGINE TO FRAME.
Verify that there are no damaged electric wires, that there are no leaks from
hoses, tank, carburettor or engine’s crankcase, that the propeller is not
damaged or loose, that the exhaust-pipe has no cracks, that the frame is not
bent or broken because of falls, that rubber mounts are not cracked, that the
reduction belt is not loose and every bolt is tight.
Finally you can start the engine, leaving it to warm up at a speed of 3000 to
4000 rpm with head temperature at least 120 °C, before start taking off so to
avoid piston seizing.
FUEL
Use for the mixture only premium gas for cars 8 octane, together with good-
quality, synthetic oil for mixtures at a quantity of 2.2% /2,5%.
DO NOT USE MIXTURE ALREADY DONE AT PETROL PUMPS.
When you prepare the mixture, make sure that the can has not dirt or water in
it, filter the fuel with cotton white textile into a clean can and then add the oil.
Never run the engine without the air-filter, because dirt and dust raised by the
propeller can damage it.
RUNNING-IN
All CORS-AIR engines, before being delivered, are subject to a severe
quality-check, in order to verify if all the components respect the fixed
parameters, but a further running-in is anyway necessary.
A GOOD RUNNING-IN WILL PROLONG THE LIFE OF YOUR ENGINE.
Go to a quiet place, put a thick rubber carpet under your unit to avoid that
stones or other things damage the propeller by putting it on earth and let
the engine work at a speed of 2500 rpm for 5 minutes, then regulate speed at
3000/3500 rpm for 15 minutes, then at 4000 rpm for other 15 minutes.
Switch off the engine and check that there are no loose nuts or bolts and that
every component is ok.
