4.2.3 Refuelling
4.2.3.1 Preferably fuel is transferred from a can where the correct amount of oil
is added and mixed prior to filling, see 4.2.3.3a). Refuelling is also
possible via the tank filler opening on the fuselage exterior surface, see
4.2.3.3b).
4.2.3.2 Use only super two stroke oil, specification TS C3 respectively API TC
or better quality. The SOLO company recommends CASTROL Super
TT two-stroke oil.
4.2.3.3 a) Refuelling with the electric pump system
part no. Z 02/2.
Insert plug F in the socket which is fixed at the filler hose in the
aircraft and switch on the main switch of the aircraft and the engine
master switch.
Couple hose A to the pump system and hold it into your fuel canister.
Couple the pump system via coupling D to the fuselage side filler
hose (in baggage compartment). Switch on the pump via switch E.
Note for a) and b): A built in device automatically switches off the
current to this socket as soon as the fuselage tank is full.
b) Refuelling via a permanently installed refuelling pump (Option)
Couple the fuel filler hose via a coupling (like D see above) to the
fuselage side filler hose. Switch on the engine electrics and the pump
via a switch located in the fuselage main-bulkhead (behind the pilots
left shoulder). Don’t forget to switch off after refuelling!
From serial No. 8-173 on: Start the pump by pressing the push button
located in the fuselage main-bulkhead (behind the pilots left shoulder).
As soon as the fuselage tank is full a built in device automatically
switches off the pump. If you want to interrupt or to stop the filling
procedure before the tank is full you may do this by switching off the
circuit breaker for this pump (located directly below the push button)
or by switching off the engine master switch. Starting the pumping
again is only possible by pressing the push button. This system shall
prevent the pump from running inadvertently.
c) Refuelling via the tank filler opening on the fuselage exterior
surface
If you can't fill with premixed fuel, half fill the tank with fuel, then
add the proper amount of oil and fill up completely.

Flight manual DG-800B
Calibration: A device in the DG-800B automatically cuts off the
electric power for the pump system as soon as the fuselage tank is
filled and executes a calibration of the fuel gauge.
If you don't use a pump for filling (see a) or b)), the calibration can be
done manually: With full tank switch off the engine master switch.
Press the upper button of the engine time indicator in the DEI, while
switching on the engine master switch.

correct fuel quantity indication. This must be done at least each time
you change the fuel type or quality.
4.2.3.4 Storage of the pump system (see a)
To increase the lifetime of the pump it is better not to empty the pump,
but to store the pump filled with fuel. Therefore remove hose A by
disengaging the coupling . The couplings C + D are closing the fuel lines
to the pump when disengaged.
4.2.3.5 Wing fuel tanks (Option)
A) Filling can only be done by using the seperate electric pump system
Z 02/2. Therefore the fuselage tank should not be filled completely,
otherwise the pump system will switch off.
1. Close the wing tank valves in the fuselage.
2. Place the wing tip of the tank to be filled on the ground.
Connect the pump system and fill the wing tank. Fill in max. 15l (3.96
US gal).
3. After filling the wing tank connect the fuselage connector to the wing
connector.
B) Caution: Empty the wing fuel tanks prior to derigging.
Don't park the rigged glider with filled wing fuel tanks for extended
periods!
4.2.3.6 In case there is no can available for premixing the fuel and oil for filling
the wing tanks, the fuselage tank can be used. Transfer approx. 5 litres
(1.3 US gal.) of fuel into the fuselage tank, pour in the oil and fill the
tank with fuel. Then fill the wing tanks (option) from the fuselage tank.
4.2.4 Derigging
Derigging follows the reverse of rigging. Water ballast must be dumped
before derigging.
Transfer the fuel from the wing tanks (Option) to the fuselage tank or
empty the wing tanks using the electric pump system in reverse.
Disconnect the connectors from the wing fuel tanks.
The airbrakes must be locked.
