FIRST STARTING
Once the installation is completed, before the first starting is carried out, follow the instructions
below:
Recheck all the connections of the various pipes, gasoline and air.
Visually check that there are no electrical parts or pipes accidentally leaned (or very near)
against the engine exhausts since they reach within few seconds temperatures like 700/900
° C.
Visually check that there are no electrical parts or fittings leaned accidentally against sharp
edges.
Visually check that there are no electrical wires or pipes near the engine rotating parts.
Activate the fuel pumps and check that there are no leaks nor drips
Check that the carburettors butterflies are at the minimum (closed)
Adopt any other necessary precautions.
Proceed with the first starting (without propeller and with fly-wheel instead of propeller) with closed
accelerator in an open and proper place, away from people especially if not employees.
Whenever you turn the engine on without propeller it is necessary that a flywheel
must be installed in its housing; this flywheel must have the weight, the
dimensions and especially the moment of inertia similar to the propeller used, as
indicated by the engine manufacturer. Keep the throttle to minimum to avoid that
possible unusual revs could damage the engine.
After having completed all the controls to the minimum fix the plane in a fixed point, considering
that the propeller may develop a traction even of 250 / 300 kg. After having activated the brakes
and locked the plane, using wedges under the wheels or proper strings, simulate and check the
functionality of mechanical Fuel Pump, leave it work alone, with electrical fuel pump switch-off and
check the pressure and normal functionality of the engine
