STARTER AIR CLEANER HOW TO START IF BATTERY iS LOW

FIG, 20

This cleaner (A, Fig. 20), is designed to keep

pieces of grass, chaff, etc., from entering the engine

cooling system. This cleaner must be cleaned every

four to eight hours depending upon conditions.

To clean, remove cleaner and tap lightly. Knead

with hands until cleaner appears to be clean. An air

hose. may be used if available. Replace air cleaner

Before starting engine.

FIG. 21

The screen (B Fig. 2t), MUST BE BRUSHED,

CLEANED FREQUENTLY, while operating tractor

to prevent engine from over-heating.

FI G. 22

1. The quickest method would be to connect quick-

start Battery cables or _jumpers" from your

automobile 12 volt Battery to the tractor Battery.

CAUTION: Connect positive (+) terminal to

positive (+) terminal.

2. Method number two will NOT charge battery,

but is strictly emergency starting only.

Remove machine screws (C, D and E, Fig.

2t). This will allow removal of belt guard

assembly (F, Fig. 21).

Loosen nut (G, Fig. 22), and push motor-

generator forward. This will take tension

from V-belt. Remove bett.

c. Secure a piece of rope and tie a knot in one

end. Place this knot into notch in engine

pulley, refer to Fig. 22.

d. Wrap rope around engine pulley using grooves

provided.

e. Pull rope sharply to start engine.

DO NOT REPLACE V-BELT OR GUARD WHILE

ENGINE I$ RUNNING. The above method of starting

is only a means to get unit to nearest source of

battery charging. DO NOT operate tractor any tonger

than necessary with V_belt and guard removed. Stop

engine and replace as soon as possible. Be sure to

have proper tension on belt, retighten nut IG, Fig.

22).

IMPORTANT -BATTERY CARE

Proper attention to the battery on units so equipped

is of the utmost importance,

Your battery is of the same high standard as is

used in automobiles. Unfortunately it does not have

the advantage of automatic attention by the service

station attendant as the one in your car.

The folJowing points are recorded to help remind you

to provide attention to the battery and gain full

advantage of the usable life built into the battery

and avoid costly replacements.

1. Check solution levei in" battery at least once

each week, Add distiIled water when required

to retain the level of 3/t6" over the separators.

After adding water, run the engine so that the

generator charge will mix the solution. DO NOT

OVER" FILL RETAIN 3/t6" SOLUTION

ABOVE PLATES.

2. Keep the battery clean_ Remove any collection

of grease or other substance from the top of

the battery.

Keep top of battery clean and dry at all times.

Keep battery snug in its cradle or holder.

Keep vent caps tight and small vent holes in

caps open.

If battery should become discharged or fall

below a specific gravity of 1,225 remove battery

and have it recharged_

When recharging, request service station to

SLOW CHARGE the battery at a rate of 2

to 3 amperes° FAST CHARGlflG IS NOT RE-

COMMENDED_

WINTER CARE

1_ If unit is not used regularly during winter

months it should be removed and stored in

a cool, dry pJace_

2. If unit is used only infrequently during winter

months check at least once each thirty days to

be sure a full charge is maintained.

3. A battery not fully charged can freeze result-

ing in the necessity to replace.

4, A safe rule is to charge the battery monthly

or at least test and recharge if below 1.225

specific gravity.

Please remember the necessity of proper winter

care for the battery, Batteries not in use for several

months and not kept fully charged produce a suJpha-

tion of the p_ates which cannot be removed by

recharging.

Your guarantee is intended to provide you adequate

protection. It does not, however, cover recharging

or damage resulting from lack of care, freezing or

inability to perform after winter or long storage

periods without proper attention.

TIRES

Keep tires inflated to 15 pounds of air in frontt 8

pounds in rear. To repair a punctured tire, front wheel

may be removed by unsnapping "E" ring from front

spindle and sliding washer and front wheel complete

with tire from spindle. Remove rear wheel by unscrew-

ing three hub bolts from wheel and hub. A local auto°

mobile repair station can repair tire in same manner

as an automobile,

STORAGE INSTRUCTIONS

In the event your tractor is to be inoperative for

periods in excess of 30 days - prepare for storage

as outlined below:

1, Drain gas tank.

2. Drain carburetor by allowing engine to run out of gas-

oline. Then push in drain valve under carburetor bowl

to remove all gasoline from carburetor. Evaporating

gasoline will leave gum deposits if not drain complete-

ly. These deposits make fuel systems inoperative re-

suiting in a hard or non-starting engine when again

used,

3. Do not save or store gasoJine over winter,

GENERAL

Just as your automobile needs professional

mechanical maintenance from time to timer

so does your air cooled engine, Cleaning and

adjustment of the carburetor and periodic re-

placement of the spark plug and ignition points

is made necessary by NORMAL use.

Professional air cooled engine service is as

close as your nearest Sears Store.

Ayearly check up or tune up by Sears is a

good idea to avoid breakdowns or delays . ..

Do it each fall_ then you're ready for spring.

We even prepare it for storage for you,
