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. Selectthe

oil's SAE viscosity grade according to your

expected operating temperature.

oHviscchsr t4e

Change the oil after every 50 hours of opera-

tion or at least once a year if the tractor is

not used for 50 hours in one year.

Checkthe crankcase oil level before starting

the engine and after each eight (8) hours of

operation.

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 capfrom end of drain valve

and install the drain tube onto the fitting.

3. Unlock drain valve by pushing inward

slightly and turning counterclockwise.

5. After oil has drained completely, close and

lock the drain valve by pushing inward

and turning clockwise until the pin is in

the locked position as shown.

6. Remove the drain tube and replace the

cap onto the end of the drain valve.

7. Refill engine with oil through oil fill dipstick

tube. Pour slowly. Do not overfill. For

approximate capacity see "PRODUCT

SPECIFICATIONS"section of this manual.

8. Use gauge on oil fill cap/dipstick for

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.

ENGINE OiL FILTER

Replace the engine oil filter every season or

every other oil change if the tractor is used

more than 100 hours in one year.

AiR FILTER

Your engine will not run properly using a

dirty air filter. Service air cleaner more often

under dusty conditions. See Engine Manual.

CLEAN AIR INTAKE/COOLING AREAS

To insure proper cooling, make sure the grass

screen, cooling fins, and other external sur-

faces ofthe engine are kept clean at atltimes.

Every 100 hours of operation (more often

under extremely dusty, dirty conditions),

remove the blower housing and other cooling

shrouds. Clean the cooling fins and external

surfaces as necessary. Make sure the cooling

shrouds are reinstalled.

NOTE: Operating the engine with a blocked

grass screen, dirty or plugged cooling fins,

and/or cooling shrouds removed wilt cause

engine damage due to overheating.
