After checking the oil
level,
reinstall the
dip-
stick. Tighten it securely.
CHANGING ENGINE OIL
Clean
,
fresh engine oil is essential for best
performance and longer engine life. You
should
change the engine oil after the first two (2) hours
of engine operation. After this initial oil
change,
change the oil every ten (10) hours of
operation.
If you are operating under very dusty or
dirty
conditions,
change the engine oil even more fre-
quently.
Always use oil that is classified
SF,
SE, SD, or
SC. Use SAE 30 weight oil (SAE 10W30 is an
acceptable substitute) when the outside temper-
ature is above
32°F.
Do not use
10W40.
For win-
ter
use,
see the engine
manufacturer's
Engine
Owner's
Manual supplied to
you.
The
engine
oil capacity depends on the model
tiller:
the
Econo-Horse's
Tecumseh engine is
ap-
proximately 19 ounces: the Pony's Briggs engine
is about 20 ounces or to the top of the oil fill
tube
;
the Junior's Tecumseh engine is about 21
ounces or to the top of the oil fill tube.
To change the
engine
oil:
1.
Run the engine until it is warm and then shut it
off. Warm oil drains more easily and also carries
more of the contaminants away.
2. Note the drain plug on either side of the en-
gine base. Use the plug that's more convenient.

3.
Place a board beneath the
wheel
opposite the
drain plug
you'll
be using.
4.
Place a pan beneath the drain
plug.
5. Use a 3/8" open
end
wrench to remove the
drain plug. Let the oil drain into the
pan.
6. Clean the drain plug's threads and reinstall it.
Be sure to tighten the
drain
plug very securely.
7. Refill the engine crankcase
with
fresh
oil.

Check the engine oil level carefu
lly.
Depending upon the engine you
have,
use either
the dipstick or inspect the
level
in the oil
fill
tube.
AIR CLEANER SERVICE
Your engine is equipped with an air cleaner
whose purpose is to filter the air before entering
the carburetor. Frequent air cleaner service is
essential for performance and long engine life.
The Econo-Horse and Pony have dual ele-
ment air
cleaners.
The Junior has a single ele-
ment air cleaner. Each differs in service require-
ments as noted:
Econo-Horse (see Photo 5-8)-clean and re-
oil the outer foam element every 10 hours;
re-
place the inner paper filter every 50 hours or an-
nually if 50 hours is not
reached.
