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 preventdamage 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 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.

ENGINE

LUBRICATION

Only use high quality detergent oil rated

with API service classification SG-SL. Se

lect the oil’s SAE viscosity grade according

to your expected operating temperature.

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)

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.

checking level. For accurate reading,

insert dipstick into the tube and push

down firmly into place before removing.

Keep oil up to, but not over, the “FULL

line on dipstick. Push dipstick down firmly

into the tube when finished.

AIR FILTER

Your engine will not run properly using a

dirty air filter. Service paper cartridge every

two months or every 25 hours of operation,

whichever occurs first. Service paper car

tridge more often under dusty conditions.

Replace the paper cartridge annually, or

after every 100 hours of operation.

TO SERVICE CARTRIDGE

• Replace a dirty, bent, or damaged car

tridge. Handle new cartridge carefully;

do not use if the rubber seal is dam

aged.

NOTE: Do not wash the paper cartridge

or use pressurized air, as this will damage

the cartridge.
