TRANSAXLE COOLING
The transmission fan and coolingfinsshould
be kept clean to assure proper cooling.
Do not attempt to clean fan or transmission
while engine is running or while the trans­
mission is hot. To prevent possible damage
to seals, do not use high pressure water or
steam to clean transaxle.
• Inspect cooling fan to be sure fan
blades are intact and clean.
• Inspect cooling fins for dirt, grass clippings
and other materials. To preventdamage to
seals, do not use compressed air or high
pressure sprayer to clean cooling fins.
TRANSAXLE PUMP FLUID
The transaxle was sealed at the factory and
fluid maintenance is not required for the life
of the transaxle. Should the transaxle ever
leak or require servicing, contact your near­
est Sears or other qualified service center.
V-BELTS
Check V-belts for deterioration and wear after
100 hours of operation and replace if neces­
sary. The belts are not adjustable. Replace
belts if they begin to slip from wear.
ENGINE
LUBRICATION
Only use high quality detergent oil rated
with API service classification SG-SL. Se­
lect the oil’s SAE viscosity grade according
to your expected operating temperature.
Change the oil after every 50 hours of op­
eration or at least once a year if the tractor
is not used for 50 hours in one year.
Check the crankcase oil level before start­
ing the engine and after each eight (8)
hours of operation.

cap onto the end of the drain valve.
7. Refill engine with oil through oil fill dipstick
tube. Pour slowly. Do not overfill. For
approximate capacity see “PRODUCT

8. Use gauge on oil fill cap/dipstick for
checking level. For accurate reading,
insert dipstick into the tube and push
down firmly into place before removing.
Keep oil up to, but not over, the “FULL
line on dipstick. Push dipstick down firmly
into the tube when finished.
AIR FILTER
Your engine will not run properly using a
dirty air filter. Service paper cartridge every
two months or every 25 hours of operation,
whichever occurs first. Service paper car­
tridge more often under dusty conditions.
Replace the paper cartridge annually, or
after every 100 hours of operation.
TO SERVICE CARTRIDGE
• Replace a dirty, bent, or damaged car­
tridge. Handle new cartridge carefully;
do not use if the rubber seal is dam­
aged.
NOTE: Do not wash the paper cartridge
or use pressurized air, as this will damage
the cartridge.
