3.3 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.
