then RED bat tery cable and remove
battery from tractor.
3. Rinse the battery with plain water and
dry.
4. Clean terminals and battery cable ends
with wire brush until bright.
5. Coat terminals with grease or pe tro leum
jelly.

TRANSAXLE MAINTENANCE
The transmission fan and cooling fins should
be kept clean to assure proper cooling. Do
not attempt to clean fan or trans mis sion while
engine is running or while the trans mis sion
is hot. To prevent pos si ble damage to seals,
do not use high pres sure 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 prevent damage to
seals, do not use compressed air or high
pressure sprayer to clean cool ing fins.
TRANSAXLE PUMP FLUID
The transaxle was sealed at the factory and
fluid main te nance 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 ad just able. Re place
belts if they begin to slip from wear.
ENGINE
LUBRICATION
Only use high quality detergent oil rated with
API service classification SG-SL. Select the
oil's SAE viscosity grade according to your
expected operating temperature.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
NOTE: Although multi-viscosity oils (5W30,
10W30 etc.) improve starting in cold weather,
they will result in increased oil consumption
when used above 32°F/0°C. Check your engine
oil level more frequently to avoid possible
engine damage from running low on oil.
Change the oil after every 50 hours of
operation or at least once a year if the tractor
is not used for 50 hours in one year.
Check the crankcase oil level before starting
the engine and after each eight (8) hours
of operation. Tighten oil fill cap/dipstick
securely each time you check the oil level.
