Refueling is performed as follows:
1. Power up the jet system and enter maintenance mode to partially
extend the engine.
2. Ensure that the fuel tank vent hole is clear. This is done by visually
inspecting the vent hole, located in the wheel box.
3. Connect the refueling tube to the refueling/de-fueling quick
connector located in the engine box on right. (Figure 4-3)
4. Ensure the fuel shut off switch, positioned on the left-hand side of
the cockpit, is in the “OPEN” (forward) position.
5. Switch the re-fueling switch in the engine box (right hand side
above the circuit breakers) to the “
forward
” position for refueling.
6. When the tanks are full (determined by visual inspection of top
tank) or the desired amount of fuel has been dispensed, the
refueling/de-fueling switch must be switched
to “
OPR
”
and the
refueling tube disconnected.
CAUTION:
Monitor the fuel quantity during refueling. Although fitted
with an over-pressure sensor, do not rely on this feature-
overpressure may damage the tanks.
CAUTION:
The fuel pump requires fuel for lubrication and cooling. Do
not operate without fuel as this will cause permanent
damage to the pump.
CAUTION:
Ensure refueling tube is kept free of contamination. Dirt
and dust will reduce reliability of the system.
CAUTION:
Keep the Jet system powered up while refueling, to avoid
the pylon moving unintentionally.
CAUTION:
Ensure the correct fuel pre-mix with the correct oil is used.
Incorrect fuel may destroy the engine.
