2. Rinsethe batterywith plain water and
dry.

TRANSAXLE COOLING
The transmissionfan and coolingfins
should be kept clean to assure proper
cooling.
Do not attempt to clean fan or transmis-
sion while engine is runningor whilethe
transmissionis hot. To prevent possible
damageto seals, do not usehigh pressure
water or steam to clean transaxle.
Inspectcooling fan to be sure fan blades
are intact and clean.
Inspectcooling fins for dirt, grass clip-
pings andother materials. To prevent
damageto seals, do not use com-
pressedair or high pressure sprayer to
clean coolingfins.
TRANSAXLE PUMP FLUID
The transaxle was sealed at the factory
and fluid maintenance is not required for
the life of the transaxle. Should the trans-
axle ever leak or require servicing, contact
your nearest Sears or other qualified
service center.
NOTE: Although multi-viscosity oils
(5W30, 10W30 etc.) improve starting in
cold weather, they will result in increased
oil consumption when used above 32°E
Check your engine oil level more frequent-
ly to avoid possible engine damage from
running low on oil.
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. Tighten oil fill cap/
dipstick securely each time you check the
oil level.
TO CHANGE ENGINE OIL
Determine temperature range expected
before oil change. All oil must meet API
service classification SG-SL.
Be sure tractor is on level surface.
Oil will drain more freely when warm.
Catch oil in a suitable container.
1. Remove oil fill cap/dipstick. Be careful
not to allow dirt to enter the engine
when changing oil.
2. Remove yellow cap from end of drain
valve and install the drain tube onto the
fitting.
