Introduction
Section 4 provides checklist and amplification procedures for the conduct
of normal operation.
Normal procedures associated with optional systems can be found in
section 9.
4.2
Rigging and derigging, filling the watertanks, refuelling
4.2.1 Rigging
1. Open the canopy.
2. Clean and lube the pins, bushings and the control connections.
3. With a helper on the wingtip, push the right wing into place, then the
left wing. All controls will hook up automatically. The flaperons should
be held at neutral for rigging, airbrakes locked.
Sight through the wing main pin bushings to determine alignment. Push
the main pins in as far as possible. Turn the handles up to the fuselage
wall, while pulling out the white securing knob, then release the knob
back to its locked position.
4. Rigging of the stabilizer
Set the trim nose down.
Set the stabilizer on top of the vertical fin, so that the roller at the
fuselage side push rod is inserted into the funnel at the elevator.
Watch carefully the procedure.
When the stabilizer is set down
and laying on the fin, push it
aft. The roller will slide for-
ward in the funnel if you hold
the elevator in the pertinent
position.
With a 13 mm wrench (supplied with
your glider) tighten the front mounting bolt firmly (the brass securing
sleeve will be pushed down by the wrench). Then rotate the bolt head a
little back and forth so that the securing sleeve engages.
The securing sleeve should move up so far, that its upper surface is
even with the upper surface of the bolt head.

Flight manual DG-800B
Check for correct elevator connection by looking through the plexiglas
window at the upper surface of the stabilizer.
5. Tape the gaps of the wing-fuselage junction.
6. Positive control check.
4.2.2 Filling the watertanks
Pull back the handle for the right tank (top handle). Place the right wing
tip on the ground.
Attach the hose in the water outlet on the lower surface of the wing.
Fill with water. Close the valve.
Place the left wing tip to the ground and fill the left tank accordingly.
Filling with water ballast is only allowed with a filling system which
enables you to determine the exact amount of ballast filled in, e.g. water
gauge or calibrated canisters.
Warning: Fill the hose from your water containers but never from a
mains pressure water supply.
Filling the wing tanks with excessive pressure (more than 0.2 bar, 3 psi)
will definitely burst the wing shell!
Caution: If the tanks are to be filled up completely you must suck the air
out of the tanks with the filling hose.
Fill with the desired amount of water regarding the loading chart see
sect. 6.
In case a valve leaks slightly, you may try to pull out the PVC pushrod of
the valve to stop the leak. If this cannot be done successfully refer to
maintenance manual 1.8.2. and 4.1.
It is not allowed to fly with leaking watertanks,as this may result in
asymmetrical loading condition.
After filling the tanks, check to see if the wings are balanced. If one wing
is heavier, dump enough water to balance the wings.
Warning: Follow the loading charts in section 6.8.
The respective max. T.O.W. for selflaunching and for tow launching are
not to be exceeded.
