Engine Oil
OIL LEVEL CHECKING
Check daily. The level can be checked with the body raised.
Ensure the body prop is in place.
The dip stick
(A)
is located on the right hand side of the engine and is reached by standing on the
walkway
(B)
.
Extreme care must be taken when working from the walkway, particularly in wet
conditions.
OIL CHANGING
At the frequency specified in the Maintenance Schedule. Oil specifications are shown in the
lubrication diagram - see later in this chapter. The oil is best drained whilst warm via the remote
drain plug
(C)
.
Cold Weather Precautions
The cooling system
(D)
must be filled with equal quantities of antifreeze and water to maintain a
minimum concentration of 50%, i.e. -39°C. Any top ups must therefore be done with a 50% mixture
of antifreeze and water. The concentration level should be checked at the 500 hour service interval
as failure to observe this can cause corrosion of the engine block.
Ensure the auxiliary engine is not running and isolated before fan maintenance or
replacement is attempted.
