CHANGE ENGINE OIL AT THESE INTERVALS
Change the engine oil after the first two
operating hours (about one tankful of fuel).
Then, change oil every ten hours, or sooner if
tilling in dusty, dry soil. This is more often than
the engine manufacturer recommends-but it
will pay good dividends, an engine that will
last and last. It's normal for engine oil to get
black, but check the oil for grime, dirt and
grit-then, change it when needed, no matter
how few operating hours you have used that
oil.
IMPORTANT: When tilling in extremely dusty
conditions, check the oil for level and presence
of dirt, and check the air filter for dirt very
frequently. Every half hour is none too often.
Change the oil and clean the air cleaner when
they're dirty. If you take both of these actions,
your engine will last much, much longer.
For operation of all engines used on Troy-Silt
Tillers, please remember to check the dipstick
to see that engine oil is kept up close to the
"Full" mark all of the time. Always make sure
that you use the proper grade of oil in your en-
gine. SE must be printed on the top of the oil
can, or on the label. Please make sure that the
air cleaner is clean and tightly fitted before you
operate your engine. .
HOW TO PRESERVE ENGINE LIFE
When operating your tiller, please don't run
your engine at full throttle all of the time. In-
stead, try to judge when the engine is provid-
ing the proper amount of power-not too little,
but not too much. Matching engine power to
the work is easier on the engine and on the til-
ler. The sound of your engine operating will be
your best guide.
When you are through with the tiller and are
ready to put it away for the day, let it run \'It
low or idle speed for two or three minutes
without any load on the engine. In fact, let it
run at low speed during brief interludes when
you're not actually working the tiller-while
you're picking up rocks, preparing to start a
new row, or just hesitating for a moment. Thi$
practice of giving your engine a "rest" period,
will improve fuel economy and will add years
to the life of your engine. It will also cool down
a hot engine, if its cooling fins are not clogged
with dirt.
HELPFUL INFORMATION
ABOUT MOTOR OIL
We suggest that you use #30 oil that is rated
SE for the greatest engine protection against
hi9,h temperatures, oxidation, rust, corrosion
and dirt buildup. SE oil provides more reliable
protection of bearings and bearing surfaces at
high temperatures. As we have just explained,
small engines generate a lot of heat and the
oils we recommend will stand up best to that
heat. SE classified oil meets the specifications
of all engines used for Troy-Silt Tillers.
The
"s"
in "SE" means Service Oil, referring
to Automobile Service Stations. The "E" in
"SE" is the level of the oil's rating. The higher
the letter in the alphabet, the higher the tem-
perature rating for the oil.
ADDING GASOLINE
Use the proper gasoline for your engine. Don't
overfill the tank. Don't fill any closer than one
half inch from filling neck of tank. Don't smoke
while refueling. Clean gasoline spills off engine
and tiller before starting engine.
