NOTE: The original equipment battery on
your tractor is maintenance free. Do not
attempt to open or remove caps or covers.
Adding or checking level of electrolyte is
not necessary.
TO CLEAN BATTERY AND TERMINALS
Corrosion and dirt on the battery and termi-
nals can cause the battery to "leak" power.
1. Remove terminal guard.
2. Disconnect BLACK battery cable first
then RED battery 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 petroleum
jelly.
6. Reinstall battery (See "REPLACING
BATTERY" in the SERVICE AND AD-
JUSTMENTS section of this manual).
TRANSAXLE MAINTENANCE
The transmission fan and cooling fins should
be kept clean to assure proper cooling. Do
not attempt to clean fan or transmission 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 cooting fins for dirt, grass clippings
and other materials. To prevent damage to
seals, do not use compressed air or high
pressure sprayer to clean cooling fins.
TRANSAXLE PUMP FLUID
The transaxte was sealed at the factory and
fluid maintenance is not required for the life
of the transaxte. 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.

Use gauge on oil fill cap/dipstick for
checking level. Insert dipstick into
the tube and rest the oil fill cap on the
tube. Do not thread the cap onto the
tube when taking reading. Keep oil
at "FULE' line on dipstick. Tighten cap
