SERVICE AND MAINTENANCE
ENGINE MAINTENANCE
Checking the Engine Oil
Only use high quality detergent oil rated with API service classification
SF, SG, SH, or SJ. Select the oil's SAE viscosity grade according to
the expected operating temperature. Follow the chart below.
/Colder ■32°F •-WarmeA
5W20 SAE30
Oil Viscosity Chart
Although multi-viscosity oils (5W20,10W30, etc.) improve starting
in cold weather, they will result in increased oil consumption when
used above 32°F. Check your engine oil level more frequently to avoid
possible engine damage from running low on oil.
To check the engine oil, proceed as follows:

Ensure that the tractor is on a level surface.
Clean the oil fill area of any debris.
Remove the dipstick and wipe with a clean cloth.
Insert and tighten dipstick.
Remove the dipstick and check the oil level. It should be at the
Full mark on the dipstick. See Figure 7.____________________

If low, add oil slowly into the engine oil fill. Do not overfill. After
adding oil, wait one minute and then recheck the oil level.
Replace and tighten dipstick.
A CAUTION
Do not overfill. Cverfilling with oil may cause the engine to not start,
hard starting, or engine smoking. If over the FULL mark on the
dipstick, drain oil to reduce oil level to FULL mark on dipstick.

Changing Engine Oil
The engine oil should be changed in the first 5 hours and then every
50 hours or once a season. To change the engine oil, proceed as
follows:
1. With engine CFF but still warm, disconnect spark plug wire and
keep it away from spark plug.
2. Pop off the protective cap on the end of the oil drain valve to
expose the drain port. See Figure 7.
3. Remove the oil fill cap/dipstick from the oil fill tube. See Figure 7.
4. Push the oil drain hose (packed with this manual) onto the oil
drain port. Route the opposite end of the hose into an appropriate
oil collection container with a capacity great enough to collect the
used oil.
5. Release the valve by twisting and pulling the valve out. The oil will
begin to drain out of the engine.
6 . After the oil has finished draining, press the two tabs inward and
push the oil drain valve back in to lock the valve closed. Remove
the hose, twist and push in to lock valve, and re-cap the end of
the oil drain valve to keep debris from entering the drain port.
7. Refill the engine with new motor oil until the oil level on the
dipstick reads FULL. Replace the oil fill cap/dipstick.
A
CAUTION
Used oil is a hazardous waste product. Dispose of used oil properly.
Do not discard with household waste. Check with your local authori­
ties or Sears Service Center for safe disposal/recycling facilities.
Changing the Oil Filter
1. Drain the oil from the engine as described above.
2. Remove the oil filter and dispose of properly. See Figure 8 .

Before you install the new oil filter, lightly lubricate the oil filter
gasket with fresh, clean oil.
Install the oil filter by hand until the gasket contacts the oil filter
adapter, then tighten the oil filter 1/2 to 3/4 turns.
