Greasing and oiling
Once a year your glider should be carefully checked and all bearings, including
control surface hinges, should be cleaned and greased if necessary.
The various greasing points are as follows:
Flaperon drive connections at the flaperon.
Airbrake drive connection - in airbrake box, also grease the brake paddle
pivots.
Remove the access panel on the left hand cockpit wall and grease all the
pushrod guides.
Remove the baggage compartment floors and open the baggage compartment
rear cover to grease all bearings.
Remove the control column cover and grease all the bearings associated with
the control column.
Grease the rudder pedal adjustment slide.
Oil all hinge points on the undercarriage in the undercarriage box.
Clean and grease all control surfaces hinges.
Clean and grease the control hook-ups for flaperon, airbrake and elevator
control.
Clean and grease all pins and bushes of the wing and tailplane attachment.
Take off the canopy and clean and grease the locking mechanism. After
reinstalling the canopy, check the force needed for emergency release with
the red handle, using a spring balance. The force should not exceed 200 N
(44 lbs.).
Clean and grease the power plant see sect. 3.5.
Note:
The greases we recommend are lithium based pressure-resistant anti-
corrosion greases or lithium-soap greases (multi-purpose greases for rolling
element bearings).
Use thin engine oil e.g. SAE 5W30 for oiling.
Caution:
The sliding guides of the following parts are made from Teflon and
should not be greased:
Airbrake control handle 6St9 on 6St15 see diagram 3
If these parts have been greased inadvertently you have to disassemble the parts
and to clean them completely with Acetone.
