CULTIVATING TIPS
S
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
will also clear the soil of unwanted vegetation. The decomposition of this vegetation matter enriches the soil. Depending
on the climate (rainfall and wind), it may
be advisable to till the soil at the end of
the growing season to further condition
the soil.
S
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.
S
Better growth will be obtained if an area
is tilled properly and used soon after tilling to preserve the moisture content.
S
The depth stake (on the back of the cultivator) serves a dual purpose. It helps
regulate the depth of the cut and also
acts as a brake to help the operator control the speed of the cultivator.
S
Lowering the depth stake will slow the
cultivator and make it till deeper. Raising
the depth stake will allow it to move faster and till more shallow.
S
If the cultivator stops forward motion and
tries to dig deeper than necessary, move
the handles from side to side to start forward motion.
S
Cultivating is loosening or digging
around growing plants which allows the
plants to flourish.
S
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 will
allow it to move faster and till more shallow.
S
When cultivating around plants or close
areas, you may want to remove the outside tines. See “Tine Replacement” in
the Service/Adjustments section.
WARNING: Read the Owner’s
manual. Know location and
functions of all controls. Keep
all safety devices and shields in place.
Never allow children or uninstructed
adults to operate cultivator. Shut off engine before unclogging tines or making
repairs. Keep bystanders away from machine. Keep away from rotating parts
and tines. They can cause injury.
HINTS FOR DEPTH STAKE OR
WHEEL ADJUSTMENT
Seed bed preparation (4 to 6 inches
depth)
Use the depth stake. Adjust the depth stake
downward for deeper cultivation.
Light cultivation (about 1 to 2 inches
depth) with moderate growth
Heavy soil (4 inch depth or greater)
Remove the depth stake and work the tines
down with a back and forth motion to at least
a depth of 4 inches. Slowly pull the cultivator
backward allowing the soil to feed forward
over the tines.
Adjust the wheels upward to their highest or
next to their highest position. Make sure the
handles are at a comfortable height for operating the cultivator.

HOW TO CLEAN THE AIR FILTER
6. Cover the outside of the air filter with
oil. Use the same type of oil as used to
make the fuel mixture. Lightly squeeze
the air filter to distribute and remove
any excess oil.
The engine uses a foam air filter that can be
cleaned and reused. Clean and oil the air
filter every 25 hours. Clean more often in
dusty conditions. Remove and clean the air
filter as follows:
7. Put the clean air filter into the air filter
housing.
CAUTION: Never run the engine without
the air filter installed. An air filter clogged
with dust can result in loss of engine
power and can cause excessive wear or
damage to the engine. If the air filter is
clogged, clean or replace immediately.
8. Install the air filter cover and secure
with the screws as shown.
9. Connect the spark plug wire to the spark
plug.
1. Disconnect the spark plug wire from the
spark plug.
2. Remove the screws from the air filter
cover (see Figure 12). Remove the air
filter cover and the air filter.

HOW TO REMOVE AND INSTALL THE TINES
Tine Installation
References to the right or left side of the cultivator are from the viewpoint of the operator’s position behind the unit.
1. Clean and lubricate the tine shaft with a
few drops of oil.
All four tines are different and cannot be interchanged. The tines must be correctly
installed or the cultivator will not function
properly.
2. Place the inside tine on the tine shaft
and reinstall the clevis pin and hairpin.
3. When the tines are properly installed, the
letter R will be visible on the outside of
the right tine (see Figure 14). The letter
L will be visible on the outside of the left
tine.
To till around plants or in small areas, the
outside tines can be removed to reduce the
tilling width to approximately 7 inches.
carefully.
WARNING: The tines are self
sharpening and will become
quite sharp from use. Handle
The tines will all wear evenly. If the tines are
being replaced because of wear, we recommend that all four tines be replaced at the
same time. To replace the tines, do the following:

3. While wearing gloves, remove the hairpins and clevis pins that secure the tine
assemblies to the shaft (see Figure 13).
Remove the tines from one side of the
unit.

5. The cutting tips on the outside tines all
bend in toward the inside tine. When assembled correctly, the letter R on the
right side, or L on the left side, will be
visible from the outside of the unit.
6. Repeat the above steps on the opposite
side of the unit.
NOTE: Make sure the tines are installed
on the correct side of the unit.

SERVICE AND ADJUSTMENT
HOW TO ADJUST THE CARBURETOR
8. Turn the mixture adjusting screw clockwise until it is halfway between the first
position and the second position.
A dirty air cleaner will cause the engine to
run improperly or to smoke excessively. Before adjusting the carburetor, make sure the
air cleaner is clean. Never make unnecessary adjustments to the carburetor. The carburetor was set at the factory to operate
efficiently under most applications. However,
if adjustments are required, we recommend
you contact your nearest Authorized Service
Center. If you feel that you are competent to
make carburetor adjustment proceed as follows.
9. Check the engine idle speed. Start the
engine and release the throttle control. If
the tines do not turn with the throttle control is released, the idle speed is correct.
If the tines turn with the throttle control is
released, adjust the engine idle speed as
follows.
10. Have someone tilt the cultivator back on
its depth stake so that the tines are off
the ground.
WARNING: Use extreme care
when making adjustments that
require the engine to be running. Keep hands, feet, hair and loose
clothing away from all moving parts.
11. Start the engine.
12. With the throttle in the released (idle
position), turn the idle speed adjustment screw counterclockwise until the
tines stop rotating.
1. Turn the mixture adjustment screw
clockwise to until closed (see Figure 15).
WARNING: The engine governor is set at the factory. Do not
change the governor setting.
Over speeding the engine above the factory setting can be dangerous. If you
think the engine governor needs an adjustment, contact your nearest Authorized Service Center.
IMPORTANT: To prevent damage to
the carburetor or to the adjusting
screw, tighten the adjustment screws
with your fingers.
2. Turn the mixture adjustment screw
counterclockwise one turn.
3. Start the engine and let it warm up for
approximately 3 to 5 minutes. Do not adjust the carburetor when the engine is
cold.
4. If the engine runs erratically or stops after the choke lever is moved to the
CHOKE OFF position, then open the
mixture adjustment screw an additional 1/8 turn counterclockwise.
Carburetor
5. With the engine running, release the
throttle control (idle position) to make the
mixture adjustments.
6. Slowly turn the mixture adjustment
screw clockwise until the engine begins
to run erratically. Note this position.

STORAGE
SERVICE AND ADJUSTMENT
S
WARNING: Never store the cultivator indoors with fuel in the
fuel tank. Never store in an enclosed, poorly ventilated area where
fumes could reach an open flame, a
spark or a pilot light as on a furnace, water heater or clothes dryer.
IMPORTANT: Never cover the cultivator
while the engine and exhaust areas are
still warm.
NOTE: A yearly checkup or tune–up by a
Authorized Service Center is a good way
to make sure that your cultivator will provide maximum performance for the next
season.
WARNING: Do not remove gasoline while inside a building,
near a fire, or while you smoke.
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.
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 gasohol, 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.
Cultivator
S
Completely clean the cultivator.
S
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 Adjustments section.
S
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.
S
S
To prevent engine damage when the cultivator is in storage for 30 days or more, follow
the steps below:
The cross piece of the upper handle (between the lower handles) can now be
used as a carry handle. To store the cultivator 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.
F–031305L
Cover the cultivator with a suitable protective cover that does not retain moisture. Do not use plastic.
20
S
Let the engine run until it is out of gasoline.
S
Slowly pull the starter handle until you
feel resistance due to compression in
the cylinder, then stop.
S
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.
