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 inch from the top to
provide space for expansion offuel. 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 a cool, welF
ventilated place, never in the house. To
assure volatility,never buy 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 smellof 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 ofacids 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 5oz.(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 before planting.
Loose unpacked soil helps root growth.
Best tilling depth is 4 to 6 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 advisableto tillthe soilat
the end of the growingseason tofurther
conditionthe soil,
. Avoid tilling soil 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 adual purpose
(see figure, page 8) It helps regulate the
depth of the cut to auniform level and
also acts as a brake to help the 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!cultivatorstops for,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 to till 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 plants or 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
making repairs,,

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 lackof fuel
Pull the starter handle slowly until you
feel resistancedue 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,
