TRANSAXLE
COOLING
The transmission
fan and cooling
fins
should
be kept clean to assure
proper
cooling.
Do not attempt
to clean fan or transmis-
sion while engine
is running
or while the
transmission
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 clip-
pings and other materials.
To prevent
damage
to seals,
do not use com-
pressed
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 trans-
axle ever leak or require
servicing,
contact
your
nearest
Sears
or other qualified
service
center
V-BELTS
Check V-belts
for deterioration
and wear
after
100 hours of operation
and replace
if necessary.
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.
Select
the oil's SAE viscosity
grade
according
to your expected
operating
temperature.

NOTE:
Although
multi-viscosity
oils
(5W30,
10W30
etc.) improve
starting
in
cold weather,
they will result
in increased
oil consumption
when
used above
32°R
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.
