Non-compliance can result in serious injuries or death!
WARNING
WARNUNG
Be sure that ignition is switched off prior to any engine rotation of the pro-
peller.
Prevent entering of foreign substance through spark plug hole.
NOTICE
WARNUNG
It is recommended that the lower spark plugs be removed to help prevent foreign ma-

not available. The procedure may take longer without air pressure.
Using a compressed air line, pressurize the oil tank through its vent nipple (pos. 6 on
Fig. 1) (on the neck of the tank). Adjust the compressor outlet regulator so that the air
line pressure is between 0.4 (5.8 psi) and 1 bar (15 psi). Do not exceed 1 bar (15 psi).
The oil tank bayonet cap is not pressure-tight, some air can escape.
Non-compliance can result in serious injuries or death!
WARNING
WARNUNG
Do not remove oil tank or cover before ensuring that air pressure has been
completely released from the tank.
Do not use the starter for this purpose. Fit propeller and use it to turn the engine.
The oil tank may become empty and as result introduce air into the oil sys-

tem. Pay attention to the oil level and fill tank as required.
Turn the engine by hand in direction of normal rotation until the first pressure indica-
tion on the oil pressure gauge of engine instrumentation in the cockpit. Normally this
will take approx. 20 turns. Depending on installation it may take up to 60 turns.
Stop the pressurization. Allow air pressure to bleed off.
Remove the cap(s) (pos. 7 on Fig. 1) from the oil tank and reconnect the engine oil
return line(s) (pos. 5 on Fig. 1) to the tank.
NOTICE
Re-fit the spark plugs. Restore aircraft to original operating condition.

SERVICE INSTRUCTION
Procedure
Procedure
Ensure that the suction oil line (pos. 1 on Fig. 1) and oil return
line(s) (pos. 2 on Fig. 1) are connected to the proper fittings on the
oil tank. If the oil lines from the engine to the oil tank are incorrectly
connected, severe engine damage may result.
Procedure
See relevant MML on spark plug fitting and correct torque. If need-
ed re-apply heat compound to threads.
