How To Mix The Fuel Mixture

The two cycle engine, used on this cultivator,

requires a mixture of gasoline and oil for lu-
brication of the bearings and other moving

parts. The correct fuel mixture ratio is 24:1

(5.2 oz. oil per one gallon of gas - see the

Fuel Mixture Chart). Gasoline and oil must
be pre-mixed in a clean gasoline container.

Always use fresh, clean, unleaded gasoline.

Mix gasoline and oil as follows:

1. Pour one (1) U.S. quart of fresh, clean,

2. Add 5.3 ounces of clean, high quality,

fuel container. Do not smoke

the engine. When inside an enclosure,
do not fill the fuel tank. Before you add

the fuel mixture, stop the engine. Let the

IMPORTANT: Do not use outboard mo-

tor oil or multi-viscosity oils,such as

10W-30 or 10W-40.

3.

install the fuel cap onto the gasoline con-

tainer. Vigorously shake the gasoline
container to mix the oil with the gasoline.

4.

Add an additional three (3) U.S. quarts of
gasoline to the gallon container. Again

CULTIVATING TIPS

OPERATION

Tilling is digging in, turning over and

breaking up packed soil before planting.
Loose unpacked soil helps root growth.

Best tilling depth is 4 to 6 inches. A tiller

wiII also clear the soil of unwanted vege-
tation. The decomposition of this vegeta-

tion matter enriches the soil. Depending

on the climate (rainfall and wind), it may
be advisable to tilI the soil at the end of

the growing season to further condition
the soil.

Avoid tilling soil that is too dry as it will

pulverize and produce a dust that will not
hold water. Also, tilling soil that is too wet

will be hard on the machine and produce

unsatisfactory clods.

Better growth will be obtained if an area
is tilled properly and used soon after till-

ing to preserve the moisture content.

The depth stake (on the back of the culti-
vato o serves a dual purpose. It helps

regulate the depth of the cut and also
acts as a brake to help the operator con-

trol the speed of the cultivator.

Lowering the depth stake will slow the
cultivator and make it till deeper'. Raising

the depth stake will allow it to move fast-

er and till more shallow.

If the cultivator stops forward motion and

tries to dig deeper than necessary, move
the handles from side to side to start for-

ward motion.

Cultivating is loosening or digging
around growing plants which allows the

plants to flourish.

When using the cultivator to remove
weeds, it is best to cultivate no deeper

than 1-1/2 inches. Cultivating deeper will

only pull to the surface ungerminated

weed seeds. Raising the depth stake wilI

allow it to move faster and till more shal-
low.

When cultivating around piants or close

areas, you may want to remove the out-
side tines. See "Tine Replacement" in

the Service/Adjustments section.

manual. Know location and
WARNING: Read the Owner's

functions of all controls. Keep

all safety devices and shields in place.

Never allow children or uninstructed

adults to operate cultivator. Shut off en-
gine before unclogging tines or making

repairs. Keep bystanders away from ma-

chine. Keep away from rotating parts
and tines. They can cause injury.

_lb ARNING: Never store the cul-

closed, poorly ventilated area where
fumes could reach an open flame, a

spark or a pilot light as on a furnace, wa-
ter heater or clothes dryer.

_lb ARNING: Do not remove gas-

Gasoline fumes can cause an explosion
or a fire.

When the cultivator is put in storage for thirty
days or more, follow the steps below to

make sure the cultivator is in good condition

the following season.

Cultivator

tivator indoors with fuel in the
fuel tank. Never store in an en-

oline while inside a building,
near a fire, or while you smoke.

Completely dean the cultivator.
Remove the tines. Clean and apply oil to

the tine shafts. Mount the tines onto the
tine shafts. See "How To Remove And

Install The Tines" in the Service And Ad-

justments section.

Loosen the knobs that secure the upper
handle to the lower handle. Carefully fold

the upper handle. Make sure the throttle

cable is not bent. Tighten the knobs.

The cross piece of the upper handle (be-
tween the lower handles) can now be

used as a carry handle. To store the cul-

tivator up off the floor and out of the way,
the cross piece can also be hooked over

a wall hook.
Put the cultivator in a building that has

good ventilation.

Cover the cultivator with a suitable pro-

tective cover that does not retain mois-
ture. Do not use plastic.

IMPORTANT: Never cover the cultivator

while the engine and exhaust areas are
still warm.

NOTE: A yearly checkup or tune-up by a

Sears Service Center is a good way to

make sure that your cultivator will pro-

vide maximum performance for the next

season.

Engine

IMPORTANT: It is important to prevent

gum deposits from forming in fuel system

parts such as the carburetor, fuel filter,

fuel hose, and tank during storage. Also,

using alcohol-blended fuels (called gaso-
hol, ethanol or methanol) can attract

moisture which leads to separation and

formation of acids during storage. Acidic
gas can damage the fuel system of an en-

gine while in storage.

To prevent engine damage when the cultiva-
tor is in storage for 30 days or more, follow
the steps below:

Let the engine rununtil it is out of gaso-
line.

Slowly pull the starter handle until you

feel resistance due to compression in
the cylinder, then stop.

Slowly release the starter rope. This
position will close both the intake and the

exhaust ports and help prevent corrosion
of the piston and cylinder.
