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 operating under very dusty or dirty condi­
tions, change engine oil more frequently.
Always use oil that is classified SF, SG, SH,
or SH/CD, Use SAE30 weight oil when tempera­
ture is above 32°F (Tecumseh engines) or 40°F
(Briggs & Stratton engines). Do not use SAE
10W40. For complete motor oil specifications for
your engine, refer to Pages 48-49 or the sepa­
rate engine manufacturer literature sent to you.
The engine oil capacity depends on the model
tiller you have. Refer to the engine manufacturer
literature supplied to you for all engine oil capac­
ity specifications.
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 which may be located on
either side of the engine base.
3. Place a board beneath the wheel opposite the
drain plug you’ll be removing.
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.
8. Check the engine oil level carefully. 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 it enters
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. All differ in service require­
ments as noted:
Econo-Horse (see Figure 5-8). On this hori­
zontal-style cleaner, clean and re-oil the outer
foam element every 25 hours; replace the inner
paper filter every 100 hours or annually if 100
hours is not reached.
