Use only clean screws and nuts and always check threads for damage. If in doubt, always
renew them.
Once loosened, always renew ‘stiff’’ nuts, i.e. self–locking nuts.
Always use the specified torque values.
Whenever components are disturbed, always renew gaskets, seals, jointing material, O–rings
and sealant
Do not use additives with the oils.
Copper slip anti–seize must be used on spark plug and exhaust flange nuts.
It is
VITAL
that all coolant and oil systems are bled before attempting to operate the engine

Notes for engine installers
COOLING SYSTEM
Arrangement must be made by the engine installer to carry the rotor cooling air out from the
front plate elbow, if fitted, to the oil separator or some suitable mean of removing the oil
entrained in the cooling air before allowing it to vent overboard.
Cooling air should be arranged to flow over the engine and exhaust system whenever the
engine is in operation.
An ample supply of cold air must be available to the induction air and rotor cooling fan filters
whenever the engine is in operation.
On no account should this rotor cooling air be used directly
for cabin heating it may contain products of combustion
including CO & CO
2
.
On no account should the engine be run without either of
the air intake filters in place.
