gine. Know how to stop the unit and disen
gage the controls quickly.

2. Never allow children to operate the tiller.

Never allow adults to operate the tiller
without proper instruction.

3. Keep the area of operation clear of all

persons, particularly children and pets.

4. Keep in mind that the operator or user is

responsible for accidents or hazards oc
curring to other people, their property, and
themselves.

Preparation

1. Thoroughly inspect the area where the
tiller is to be used and remove all foreign
objects.

2. Be sure all tiller controls are released

and both wheels are in the Wheel Drive po
sition before starting the engine.

3. Do not operate the tiller without wearing

adequate outer garments. Avoid loose gar
ments or jewelry that could get caught in
moving parts.

4. Do not operate the tiller when barefoot

or wearing sandals, sneakers, orlightfoot­wear. Wear protective footwear that will
improve footing on slippery surfaces.

5. Do not till near underground electric ca

bles, telephone lines, pipes or hoses. If in
doubt, contact your telephone or utility
company.

6. Warning: Handle fuel with care; it is

highly flammable and its vapors are explo
sive. Take the following precautions:

a. Store fuel in containers specifically

designed for this purpose.

b. The gas cap shall never be removed or

fuel added while the engine is running.
Allow the engine to cool for several
minutes before adding fuel.

c. Keep matches, cigarettes, cigars,

pipes, open flames and sparks away
from the fuel tank and fuel container.

d. Fill fuel tank outdoors with extreme

care. Never fill fuel tank indoors. Use
a funnel or spout to prevent spillage.

e. Replace all fuel tank and container

caps securely.

f. If fuel is spilled, do not attempt to

start the engine, but move the ma
chine away from the area of spillage
and avoid creating any source of ig
nition until fuel vapors have dissi
pated.

7. Never make adjustments when engine Is

running (unless recommended by manu
facturer).

Operation

1. Do not put hands or feet near or under
rotating parts.

2. Exercise extreme caution when on or

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

3. After striking a foreign object, stop the

engine, remove the wire from the spark
plug wire and prevent it from touching the
spark plug. Thoroughly inspect the ma
chine for any damage and repair the dam
age before restarting and operating the
machine.

4. Exercise caution to avoid slipping or fall

ing.

5. If the unit should start to vibrate abnor

mally, stop the engine, disconnect the
spark plug wire and prevent it from touch
ing the spark plug, and check immediately
for the cause. Vibration is generally a
warning of trouble.

2. Using two 5/16"-18 x 1-1/2" screws (G),

5/16" split lock washers (H) and 5/16"-18

hex nuts (I), loosely attach the handlebar

support (A) using the upper holes. Tighten
the two screws securely.

3. There are three height adjustment holes

in the two handlebar support brackets (E

and F, Fig. 2-2). Use a setting that will po

sition the handlebars at approximately

waist level when the tines are 3"-4" into the

soil. Loosely attach the support brackets to

the outside of the handlebar assembly (K)

using two 5/16"-18x 1-1/2” screws (G), 5/

16" split lock washers (H) and 5/16"-18 hex

nuts (I). NOTE: If a support bracket will not

move, loosen attaching screw (J) and nut.

IMPORTANT: The support brackets must

be assembled to the outside of the

handlebar assembly.

4. Tighten all handlebar mounting hard

ware securely.

STEP 3: MOVE TILLER OFF CRATE

To roll the tiller off the shipping platform,

put the wheels in freewheel, as follows:

1. Place a sturdy block under the transmis

sion to raise one wheel about 1" off the

ground.

2. Remove the hairpin cotter (L, Fig. 2-3)

and wheel drive pin (M) from the wheel

hub (0) and wheel shaft (N).

3. Slide the wheel fully inward on the wheel

shaft (N. Fig. 2-3). Reinstall the wheel

drive pin (M) through the wheel shaft only

(not through the wheel hub). Secure the
wheel drive pin with the hairpin cotter (L),
pushing the hairpin cotter in as far as it will
go. The wheel should now spin freely

(freewheel) on the wheel shaft. Repeat
with the other wheel.

4. Use the handlebar to roll the tiller to a

flat area.

STEP 4: INSTALL FORWARD
CLUTCH CABLE

1. Carefully unwrap the forward clutch ca
ble (cable without an attached knob) from
its shipping position and slide the thin ca
ble wire (T, Fig. 2-4) into the slot in the ca
ble bracket. Push the cable connector (U.
Fig. 2-4) up through the hole in the bracket
until the groove in the connector snaps
into place.

2. Thread the #10-24 hex nut (Z, Fig. 2-5)

halfway onto the screw (V) which runs

through the spring (W, Fig. 2-5).

3. Thread the screw (V) into the cable ad

juster (X).

IMPORTANT: Before starting the engine,

the wheels must be placed in the WHEEL

DRIVE position (pins through wheel hubs
and wheel shaft). This procedure is
described in Wheel Drive Pins 'm Section 3.

Fig. 2-4: Instaiiing forward dutch cabie bracket and cabie.

4. Check for correct tension on the forward
drive belt by taking two measurements of
the cable spring, as follows:

a. With the Forward Clutch Bail (Y. Fig. 2

6) in an open (released) position, measure
the length of the cable spring (W) from the
outermost coil to the outermost coil.

b. Squeeze the Forward Clutch Bail against
the handlebar (see Fig. 2-7) and re-mea
sure the spring length. The belt tension is
correct if this second measurement is be
tween 1/16" to 3/16" longer than the first
measurement. If so. turn the hex nut (Z,
Fig. 2-7) tightly against the cable adjuster

(X) while preventing the cable adjuster
from turning.

c. If the spring length is incorrect, you
must adjust the cable tension as described
in Checking and Adjusting Forward Drive

Belt Tension in Section 5. Incorrect cable
tension can result in belt slippage (cable
tension too loose), or unintentional tine
movement when the clutch bail is in Neu
tral (cable tension too tight).
