BEFORE STARTING ENGINE

FILL GAS

'Thetwo cycle engine used on this mini tiller/

cultivatorrequires a mixture ofgasoline and

oil for lubrication of the bearings and other

moving parts, The correct fuel mixture ratio

is24:1 (see Fuel Mixture Chart). Gasoline

and oil must be premixed in a clean gaso-

line container. Always use fresh, clean un-

ed gasoline.

CAUTION: Gasoline is flammable

and caution must be used when handling

or storing it. Do not fill fuel tank while mini

tiller/cultivatorisrunning, hot, or when it is

in an enclosed area_Keep fuel away'from

open flame and electrical spark. DO NOT

SMOKE while mixingfuel or filling the fuel

tank_Never fill fuel tank completely, but

fill itto within !/4 - 1/2 inchfrom the top to

provide space for expansion of fuel. Al-

ways fill fuel tank outdoors and use a fun-

nel or spoutto prevent spilling. Make sure

to wipe up any spilled fuel before starting

the engine.

gasolinein a clean, approved con-

tainer, and keep the cap in place on the

containeh Keep gasoline in acool, welF

ventilated place, never in the house. To

assure volatility,neverbuy more than a

30 day supplyofgasotine_Gasoline isin-

tended to be used as a fuel for internal

combustion engines;therefore, do not

use gasoline for any other purpose. Since

many children like the smell of gasoline,

keep itout of their reach because the

fumes are dangerous to inhale, as well as

._g explosive.

WARNING: Experience indicates

that alcohol blended fuels (called gasohol or

using ethanolor 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 avoid engine prob-

lems, the fuel system should be emptied

before storage for 30 days or Ionger. Drain

the gas tank, startthe engine and let it run

until the fuel lines and carburetor are empty.

Use fresh fuel next season. See Storage

Instructions for additional information,

Never use engine or carburetor cleaner

products in the fuel tank or permanent dam-

age may occur.

GASOUNE AND OIL MIXTURE

Mix gasoline and oi!24:1 as follows:

- Pour 1 U.S. quart of fresh, clean,

unleaded automotive gasoline into a

gallon gasoline container,

- Add 5 oz.(found in carton) of clean, high

quality SAE 30 or SAE 40 two-cycle oil

intothe gasoline container.

IMPORTANT: DO NOT use Outboard

Motor Oil or Muitt-Vfscosity Oils, such

as 10W-30 or 10W-40o

• Reinstall the cap on the gasoline con-

tainer and shake container vigorously so

the oil mixes withthe gasoline.

, Add an additional 3 U.S..quarts of

gasoline to the gallon container and

shake the container again..

• Thiscompletes the special gasoline

mixing procedure. It can now be poured

into the mini tillerlcultivator fuel tank.

IMPORTANT: DO NOT Fill fuel tank

with gasoline that does not have oil mixed

in it. Do not use gasoline additives be-

cause the engine may be damaged..

TILLING HINTS

• Tilling is diggingin, turning over and

breaking up packed soil beforeplanting.

Loose unpackedsoil helps rootgrowth.

Best tilling depth is 4 to6 inches. A tiller

will alsoclear the soil of unwanted

vegetation. The decompositionof this

vegetation matter enriches the soil

Depending onthe climate (rainfall and

wind), it may be advisable to tillthe soilat

the end of the growingseason tofurther

conditionthe soil,

. Avoid tillingsoil that istoo dry as itwill

pulverize and produce a dust that willnot

hold water. Also, tillingsoilthat istoo wet

will be hard on the machine and produce

unsatisfactoryclods,

. Better growthwill be obtained intilled

ground ifa relativelysmall area istilled

properly and the tilledground is used

soon after tillingto preserve the moisture

content.

• The depth stake (on the back of the mini

tilter/cultivator)serves a dual purpose

(see figure, page 8) It helps regulate the

depth of the cut to a uniform level and

also acts as a brake to helpthe operator

controlthe speed of the mini tiller/

cultivator,

. Lowering the depth stake willslow the

minitiller/cultivatorand make it tilldeeper..

Raising the depth bar willallow itto move

faster and till more shaliowo

• Ifthe mini tiller!cultivatorstopsfor,Nard

motion and tries to dig deeper than

necessary, move the handles from side to

side to start forward motion.

WEED REMOVAL HINTS

• When using the mint tiller/cultivatorto

remove weeds, it is best totill nodeeper

than t-1/2 Inches° Tillingdeeper willonly

pull tothe surface ungerminatedweed

seeds. You may want toraise the depth

bar to lessen the braking action.

• When tillingaround plantsor close areas,

you may want to remove the outsidetines

(see Tine Replacement paragraph inthe

ServlcelAdjustments section ofthis

manual).

_ CAUTION:

• Read the Owner's manua!.

• Know locationand functions of aU

controls."

• Keep all safety devices and shields in

place,

° Never allow chiidrenor uninstructed

adultsto operate mini tiller/cultivatoro

° Shut off engine before unclogging tines or

next season.

ENGINE

IMPORTAWI': It isimportantto prevent

gum deposits from forming in essential fuel

system parts such as the carburetor, fuel fil-

ter, fuel hose or tank during storage. Also,

experience indicatesthat alcohoi blended

fuels (called gasohotor using 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 engine while in storage,

• Drain the fuel from the fuel tank into an

approved container outdoors, away from

open flame,

Start and runthe engine until it stops due

to lack of fuel

Pull the starter handle slowly until you

feel resistance due to compression

pressure, then stop,

Release the starter tension slowty to

prevent the engine from reversing due to

compression pressure_ This position wilt

close both the intake and exhaust ports to

prevent corrosion of the piston and

cyl;nder bore,
