quency at which these oil changes should be made
depends entirely on the kind of service in which
these gears are used, but even with light service the
change should be made at least once every five hun-
dred hours of operation, adding sufficient oil between
changes to keep the oil up to the oil level plug.
STORAGE OF ENGINE FOR WINTER
When the season’s work is completed, the following
instructions should be carried out very carefully to
protect the engine over winter.
The outside of the engine, including the cooling fins
on the cylinders and heads, should be thoroughly
cleaned of all dirt and other deposits.
The air cleaner, at the carburetor intake, should be
thoroughly cleaned of all oil and accumulated dust,
and the sediment removed from the oil cup at the
bottom of the cleaner.
To protect the cylinders, pistons, rings and valves
and keep them from rusting and sticking, a half and
half mixture of kerosene and good "gasoline engine"
oil (the same kind of oil as used in the crankcase of
the engine), should be injected into the pipe tap
opening on the intake manifold while the engine is
warm and running at moderate speed. About a quarter
of a pint is necessary, or enough so that a heavy
bluish smoke will appear at the exhaust. The ignition
switch should then be shut off and the engine stop-
ped. This fogging operation will leave a coating of
oil on the above mentioned parts, protecting them from
the atmosphere.
On engines where the pipe tap opening on the intake
manifold is inaccessible, the rust preventative may
be injected into the air intake on the carburetor while
the engine is running, so the mixture will be drawn
into the engine. The air cleaner connection will of
course have to be disconnected from the carburetor
to do this.
All the oil should be drained from the crankcase
while the engine is warm, as the oil will then flow
more freely than when cold.
Drain fuel system, including gasoline lines, carbu-
retor, fuel pump and tank of all gasoline, to prevent
lead and gum sediment interfering with future opera-
tion.
The air cleaner or carburetor intake, as well as the
exhaust manifold and breather openings, should be
taped or otherwise sealed off, for the duration of the
storage period.
All exposed unpainted metal parts should be coated
with grease or heavy oil.
Before starting the engine again the next season, the
crankcase drain plug should again be removed, so
that any condensation, which may have collected dur-
ing the winter, may be drained before new crankcase
oil is added.
A good plan, and one that is recommended, is to re-
move the crankcase oil base in the spring before
starting the engine for the new season, and scrubbing
off all sediment which may have collected there.
When replacing the engine base, a new gasket should
be used.
Be sure to fill the crankcase with a good quality
of crankcase oil to the high level point, before
starting the engine. Do not use any oil heavier
than SAE No. 30. Also be sure to put oll to the
proper level in the air cleaner.
It is also recommended to use new spark plugs at the
beginning of the next season, especially if the en-
gine has given considerable service.
Refuel engine and follow the starting instructions as
shown on preceding pages of this manual.
It is highly recommended that machines be stored
inside a building through the winter. If this is
not possible, the engine should be protected from
snow and ice by a proper covering.
