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.

Depending upon the engine you have, use either

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.
