TRAINING

• Read the Owner’s Manual carefully. Be thoroughly
familiar with the controls and the proper use of the
equipment. Know how to stop the unit and disengage
the controls quickly.

» Never allow children to operate the equipment. Never

allow adults to operate the equipment without proper
instruction.

• Keep the area of operation clear of all persons, particu
larly small children, and pets.

PREPARATION

• Thoroughly inspect the area where the equipment is to
be used and remove all foreign objects.

• Disengage all clutches and shift into neutral before

starting the engine (motor).

» Do not operate the equipment without wearing ad

equate outer garments. Wear footwear that will im
prove footing on slippery surfaces.

• Handle fuel with care; it is highly flammable.

• Use an approved fuel container.

• Never add fuel to a running engine or hot engine.

• Fill fuel tank outdoors with extreme care. Never fill fuel
tank indoors.

• Replace gasoline cap securely and clean up spilled
fuel before restarting.

• Use extension cords and receptacles as specified by
the manufacturer for all units with electric drive motors
or electric starting motors.

• Never attempt to make any adjustments while the
engine (motor) is running (except where specifically
recommended by manufacturer).

OPERATION

Do not put hands or feet near or under rotating parts.
Exercise extreme caution when operating on or cross

ing gravel drives, walks, or roads. Stay alert for hidden
hazards or traffic. Do not carry passengers.

After striking a foreign object, stop the engine (motor),
remove the wire from the spark plug, thoroughly in
spect the tiller for any damage, and repair the damage
before restarting and operating the tiller.

Exercise caution to avoid slipping or falling.
If the unit should start to vibrate abnormally, stop the

engine (motor) and check immediately for the cause.
Vibration is generally a warning of trouble.

Stop the engine (motor) when leaving the operating
position.

Take all possible precautions when leaving the ma
chine unattended. Disengage the tines, shift into
neutral, and stop the engine.

Before cleaning, repairing, or inspecting, shut off the
engine and make certain all moving parts have stopped.
Disconnect the spark plug wire, and keep the wire
away from the plug to prevent accidental starting.
Disconnect the cord on electric motors.

Do not run the engine indoors; exhaust fumes are
dangerous.

Never operate the tiller without proper guards, plates,
or other safety protective devices in place.

Keep children and pets away.
Do not overload the machine capacity by attempting to

till too deep at too fast a rate.
Never operate the machine at high speeds on slippery

surfaces. Look behind and use care when backing.
Never allow bystanders near the unit.
Use only attachments and accessories approved by

the manufacturer of the tiller (such as wheel weights,
counterweights, cabs, and the like).

Never operate the tiller without good visibility or light.
Be careful when tilling in hard ground. The tines may

catch in the ground and propel the tiller forward. If this
occurs, let go of the handlebars and do not restrain the
machine.

MAINTENANCE AND STORAGE

• Keep machine, attachments, and accessories in safe
working condition.

• Check shear pins, engine mounting bolts, and other
bolts at frequent intervals for proper tightness to be
sure the equipment is in safe working condition.

• Never store the machine with fuel in the fuel tank inside
a building where ignition sources are present, such as
hot water and space heaters, clothes dryers, and the
like. Allow the engine to cool before storing in any
enclosure.

DPF RATION

The operation of any tiller can result in foreign objects thrown into the eyes, which can
result in severe eye damage. Always wear safety glasses or eye shields before starting
your tiller and while tilling. We recommend a wide vision safety mask for over the
spectacles or standard safety glasses.

HOW \0 U^E YUUh TILLER

Know how to operate all controls before adding fuel and oil
or attempting to start engine.

STOPPING (See Fig. 5)

TINES

• Release forward tine control to stop forward move
ment.

• Release reverse tine control to stop reverse move

ment.

ENGINE

• Move throttle control to “STOP” position.

• Never use choke to stop engine.

FORWARD TINE CONTROL

TILLING

The speed and depth of tilling is regulated by the position
of the depth stake and wheel height.

The depth stake should always be below the wheels for
digging. It serves as a brake to slow the tiller’s forward

motion to enable the tines to penetrate the ground. Also,
the more the depth stake is lowered into the ground the
deeper the tines will dig.

DEPTH STAKE (See Fig. 6)

Adjust depth stake by removing the hairpin clip and clevis
pin. Change depth stake to desired position. Replace the
clevis pin and hairpin clip.

• For normal tilling, set depth stake at the second orthird

hole from the top.

WHEELS (See Fig. 6)

Adjust wheels by removing the hairpin clip and clevis pin.

Change wheel position. Replace the hairpin clip and clevis
pin.

• For normal tilling, set wheels at the second orthird hole
from the top.

TO START ENGINE (See Fig. 8)

CAUTION: Keep tine control in “OFF”
position when starting engine.

When starting engine for the first time or if engine has run
out of fuel, it will take extra pulls of the recoil starter to move

fuel from the tank to the engine.

e Make sure spark plug wire is properly connected.

• Place throttle control in “FAST" position.

• Move choke control to full “CHOKE” position. Grasp
recoil starter handle with one hand and grasp tiller
handle with other hand. Pull rope out slowly until
engine reaches start of compression cycle (rope will
pull slightly harder at this point).

• Pull recoil starter handle quickly. Do not let starter
handle snap back against starter. Repeat if necessary.

• If engine fires but does not start, move choke control to
half choke position. Pull recoil starter handle until

engine starts.

• When engine starts, slowly move choke control to

“RUN” position as engine warms up.

OPERATION

NOTE: A warm engine requires less choking to start.

• Move throttle control to desired running position.

• Allow engine to warm up tor a few minutes before
engaging tines.

NOTE: If at a high altitude (3000 feet) or in cold tempera
tures (below 32°F), the carburetorfuel rnixiure may need to
be adjusted for best engine performance. See “TO AD
JUST CARBURETOR” in the Service and Adjustments
section of this manual.

NOTE: If engine does not start, see troubleshooting points.

BREAKING IN YOUR TILLER

Break-in your belt(s), pulleys and tine control before you

actually begin tilling.

• Start engine, tip tines off ground by pressing handles
down and engage tine control to start tine rotation.
Allow tines to rotate for five minutes.

• Check tine operation and adjust if necessary. See
“TINE OPERATION CHECK” in the Service and Ad

justments section of this manual.

TILLING HINTS

CAUTION: Until you are accustomed to
handling your tiller, start actual field

A

To help tiller move forward, lift up the handles slightly (thus

lifting depth stake out of ground). To slow down the tiller,

press down on handles.

If you are straining ortiller is shaking, the wheels and depth
stake are not set properly in the soil being tilled. The proper
setting of the wheels and depth stake is through trial and
error and depends upon the soil condition. (The harder or
wetter the ground, the slower the engine and tine speed

needed. Underthese poor conditions, at fast speed the tiller
will run and jump over the ground).

A properly adjusted tiller will dig with little effort from the

operator.

use with throttle in slow position.

CULTIVATING

Cultivating is destroying the weeds between rows to pre
vent them from robbing nourishment and moisture from
the plants. At the same time, breaking up the upper layer
of soil crust will help retain moisture in the soil. Best
digging depth is T‘-3".

• You will probably not need to use the depth stake.

Begin by tipping the depth stake forward until it is held
by the stake spring.

• Cultivate up and down the rows at a speed which will
allow tines to uproot weeds and leave the ground in
rough condition, promoting no further growth of weeds
and grass (See Fig. 10).

tain tiller as instructed in this manual.
Some adjustments will need to be made periodically to

properly maintain your tiller.
Al! adjustments in the Service and Adjustments section of

this manual should be checked at least once each
season.

• Once a year you should replace the spark plug, clean
or replace air filter, and check tines and belts for wear.
A new spark plug and clean air filter assure proper air­fuel mixture and help your engine run better and last
longer.

CUSTOMER RESPONSIBILITIES

Disconnect spark plug wire before performing any maintenance (except carburetor adjustment) to prevent

accidental starting of engine.
Prevent fires! Keep the engine free of grass, leaves, spilled oil, or fuel. Remove fuel from tank before tipping

unit for maintenance. Clean muffler area of all grass, dirt, and debris.
Do not touch hot muffler or cylinder fins as contact may cause burns.

ENGINE

LUBRICATION

Use only high quality detergent oil rated with API service

classification SF, SG or SH. Select the oil’s SAE viscosity

grade according to your expected temperature.

SAE VISCOSITY GRADES

Op -20°
°C -30°

NOTE: Although multi-viscosity oils (5W-30,10W-30, etc.)
improve starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above
32° F (0°C). Check yourengine oil level more frequently to
avoid possible engine damage from running low on oil.

Change the oil after every 25 hours of operation or at least
once a year if the tractor is not used for 25 hours in one year.

Check the crankcase oil level before starting the engine
and after each five (5) hours of continuous use. Add SAE
30 motor oil or equivalent. Tighten oil filler plug securely
each time you check the oil level.

ACCELERATION TEST

• Move throttle control lever from “SLOW” to “FAST”
position. If engine hesitates or dies, turn idle needle
valve out (counterclockwise) 1 /8 turn. Repeat test and
continue to adjust, if necessary, until engine acceler
ates smoothly.

High speed stop is factory adjusted. Do not adjust or

damage may result.

IMPORTANT: NEVER TAMPER WITH THE ENGINE
GOVERNOR, WHICH IS FACTORY SET FOR PROPER

ENGINE SPEED. OVERSPEEDING THE ENGINE ABOVE

THE FACTORY HIGH SPEED SETTING CAN BE

DANGEROUS. IF YOU THINK THE ENGINE-GOVERNED

HIGH SPEED NEEDS ADJUSTING, CONTACT YOUR
NEAREST AUTHORIZED SERVICE CENTER/
DEPARTMENT, WHICH HAS THE PROPER EQUIPMENT
AND EXPERIENCE TO MAKE ANY NECESSARY

ADJUSTMENTS,

ENGINE

TO ADJUST CARBURETOR (See Fig. 23)

The carburetor has a high speed fixed jet and has been
preset at the factory and adjustment should not be neces
sary. However, minor adjustments may be required to

compensate for differences in fuel, temperature, altitude or

load. If the carburetor does need adjustment, proceed as

follows.

Ir general, turning the idle needle valve in (clockwise)
decreases the supply of fuel to the engine giving a leaner
fuel/air mixture. Turning the needle valve out (counter
clockwise) increases the supply of fuel to the engine giving
a richer fuel/air mixture,

IMPORTANT: DAMAGE TO THE NEEDLES AND THE
SEATS IN CARBURETOR MAY RESULT IF SCREWS ARE
TURNED IN TOO TIGHT.

PRELIMINARY SETTING

• Air cleaner assembly must be assembled to the carbu
retor when making carburetor adjustments.

• With engine off, turn idle needle valve in (clockwise)

closing it finger tight and then turn valve out (counter
clockwise) 1-1/2 turns.

FINAL SETTING

• Start engine and allow to warm for five minutes. Make

final adjustments with engine running at idle and tine
control lever in “OFF” position.

• Drain the fuel tank.

• Start the engine and let it run until the fuel lines and

carburetor are empty.

• Never use engine or carburetor cleaner products in the

fuel tank or permanent damage may occur.

• Use fresh fuel next season.
NOTE: Fuel stabilizer is an acceptable alternative in

minimizing the formation of fuel gum deposits during stor
age. Add stabilizer to gasoline in fuel tank or storage
container. Always follow the mix ratio
