BATTERY
Your tractor has a battery charging system
which is sufficient for normal use. However,
periodic charging of the battery with an au-
tomotive charger wilt extend its life.
Keep battery and terminals clean.
Keep battery bolts tight.
Keep small vent holes open.
Recharge at 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 "leak" power.
1. Disconnect BLACK battery cable first
then RED battery cable and remove
battery from tractor.
2. Rinsethe batterywith plain waterand dry.
3. Clean terminals and battery cable ends
with wire brush until bright.
4. Coatterminals with grease or petroleum
jelly.
5. Reinstall battery (See "REPLACING
BATTERY" in the SERVICE AND AD-
JUSTMENTS section of this manual).
TRANSAXLE COOLING
The transmission fan and cooling fins should
be kept clean to ensure proper cooling.
Do not attempt to clean fan or transmission
while engine is running or while the trans-
mission 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 1.
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 transaxte. Should the transaxle ever Docking
leak or require servicing, contact your nearest Position
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.
ENGINE
LU BRICATION
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
starting 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.
Remove oil fill cap/dipstick. Be careful
not to allow dirt to enter the engine when
changing oil.
Slide oil drain extension from the docking
position on the engine blower housing
and extend outward from engine.
