• Keep battery bolts tight.
• Keep small vent holes open.
• Rechargeât 6-10 amperes for 1 hour.
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
terminals can cause the battery to “leal^
power.
1. Disconnect BLACK battery cable first
then RED battery cable and remove
battery from tractor.
2. Rinse the battery with plain water and
dry.
3. Clean terminals and battery cable ends
with wire brush until bright.
4. Coat terminals with grease or petro­
leum jelly.
5. Reinstall battery (See “REPLACING
BATTERY" in the Service and Adjust­
ments section of this manual).
TRANSAXLE COOLING
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 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 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 a 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.

Check the crankcase oil level before
starting the engine and after each eight
(8) hours of operation.

before oil change. All oil must meet API
service classification SF-SJ.
