SPARK ARRESTER WARNING TO RESIDENTS OF CALIFORNIA AND SEVERAL OTHER STATES  
Under California law, and under the laws of several other states, you are not permitted to operate an internal combustion engine  
using hydrocarbon fuels on any forest, brush, hay, grain, or grass covered land; or land covered by any flammable agricultural crop  
without an engine spark arrester in continuous effective working order.  
The engine on the unit is an internal combustion engine which burns gasoline, a hydrocarbon fuel, and must be equipped with a  
spark arrester muffler in continuous effective working order. The spark arrester must be attached to the engine exhaust system in  
such a manner that flames or heat from the system will not ignite flammable material. Failure of the owner/operator of the unit to  
comply with this regulation is a misdemeanor under California law (and other states) and may also be a violation of other state  
and/or federal regulations, laws, ordinances or codes. Contact your local fire marshal or forest service for specific information  
about which regulations apply in your area.  
Do not operate this equipment if you are  
under the influence of alcohol, medication,  
or when you are tired or ill.  
d. Fill fuel tank outdoors and with ex-  
treme caution. Never fill fuel tank  
when indoors. Use a funnel or  
spout to prevent spillage.

stumps. If you are in doubt about the  
tilling conditions, always use the fol-  
lowing operating precautions to assist  
you in maintaining control of the  
equipment:  
cool before inspecting, cleaning or  
repairing.  
After striking a foreign object, stop the  
engine, let all moving parts come to a  
complete stop, disconnect the spark plug  
wire and prevent it from touching the  
spark plug, then carefully inspect the ma-  
chine for damage. Repair the damage  
before restarting and operating the  
machine.  
Remember: you can stop the tines by  
releasing the engine Throttle/Tines lever.  
Move the engine On/Off switch to OFF to  
shut the engine off.  
Never transport this machine when the  
engine is running.  
a. Stand behind the equipment, using  
both hands on the handlebar. Relax  
your arms, but use a secure hand  
grip.  
Terminals and non-insulated electrical  
parts shall be protected against shorting  
during normal servicing, refueling or  
lubrication.  
Exercise caution to avoid slipping or  
falling.  
b. Start tilling at shallow depths,  
working gradually deeper with each  
pass.  
If the machine should start to vibrate  
abnormally, stop the engine. Disconnect  
the spark plug wire and prevent it from  
touching the plug. Check immediately for  
the cause. Vibration is generally a  
warning of trouble. Fix the problem  
before using the equipment again.  
Use extreme caution when reversing or  
pulling the machine toward you.  
Start the engine carefully according to  
instructions and with feet well away from  
the tines.  
c. Clear the tilling area of all large  
stones, roots, and other debris.  
d. In an emergency, stop the tines by  
releasing the engine Throttle/Tines  
lever on the handlebar. To stop the  
engine, move the engine On/Off  
switch to OFF.  
Stop the engine, disconnect the spark  
plug wire and prevent it from touching the  
spark plug whenever you leave the equip-  
ment, before unclogging the tines, or  
when making any repairs, adjustments or  
inspections.  
MAINTENANCE/STORAGE  
Keep the Tiller/Edger, attachments and  
accessories in safe working condition.  
Do not overload the machines capacity  
by attempting to till too deeply at too fast  
a rate.  
Check all nuts, bolts, and screws at fre-  
quent intervals for proper tightness to be  
sure equipment is in safe working  
condition.  
Take all possible precautions when  
leaving the machine unattended. Always  
stop the engine. Disconnect the spark  
plug wire and prevent it from touching the  
plug.  
Never operate the equipment on slip-  
pery surfaces. Look behind and use care  
when backing up.  
Never store equipment with fuel in fuel  
tank inside a building where fumes may  
reach an open flame or spark (hot water  
and space heaters, furnaces, clothes  
dryers, stoves, electric motors, etc.).  
Do not operate the equipment on a  
slope that is too steep for safety. When  
on slopes, slow down and make sure you  
have good footing.  
Before cleaning, repairing, or  
inspecting, stop the engine and make  
certain all moving parts have stopped.  
Disconnect the spark plug wire and  
prevent it from touching the spark plug to  
avoid accidental starting.  
Allow the engine to cool before storing

Figure 7: Tine patterns.  
Adjust engine speed to suit the tilling  
conditions. Remember that the rotating  
tines help to pull the machine forward.  
Use slower speeds and a shallow depth  
setting when learning to use the unit and  
whenever you are tilling on hard, rough or  
uneven ground.  
TILLING AND CULTIVATING  
Narrow Tine Positions For a narrow,  
4-1/2" tilling width, remove the outside  
tine section on the left- and right-sides  
(B, Figure 7). See Tine Removal and In-  
stallation in Section 5 for detailed informa-  
tion on how to set up this tine position.  
WARNING  
Stony Soil Tine Positions When tilling  
deeply in stony soil, stones may become  
jammed between the inner tines and the  
machine hood. This setup swaps the two  
inner tines to minimize jamming (C,  
Figure 7). See Tine Removal and Installa-  
tion in Section 5 for detailed information  
on how to set up this tine position.  
5. Do not try to till too deeply in the first  
pass through sod or very hard ground. If  
the machine jumps or bucks, use a shal-  
lower depth setting and reduce the engine  
speed. With each succeeding pass, till  
more deeply.  
Keep away from rotating tines. Rotating  
tines will cause serious personal injury.  
Use your machine for busting sod,  
preparing seedbeds and for cultivating in  
gardens and flower beds. It is easy to op-  
erate, but it is important that you start out  
slowly and read this Section thoroughly  
before putting it to use. Let the machine  
do most of the work. The tines will pull  
the machine forward, letting you adjust  
forward speed by pressing down or lifting  
the handlebar.  
6. Apply downward pressure on the  
handlebar for shallower tilling. Lift the  
handlebar to dig more deeply. If the  
machine stays and tills in one spot, try  
swinging the handlebar from side to  
side to start it moving forward again.  
TILLING PATTERNS  
1. To make seedbeds, go over the same  
path twice in the first row, then overlap  
one-half the machine width on each suc-  
cessive pass until all rows are tilled twice  
(D, Figure 8).  
7. For easier tilling, water very hard soil a  
few days before tilling. Avoid working the  
soil when soggy or wet. Wait a day or  
two after heavy rain for the ground to dry.  
1. Roll the machine to the work area.  
2. Adjust the tilling depth to the desired  
position (see Pre-Start Preparation on the  
previous page).  
CULTIVATING  
1. Cultivating is shallow tilling that dis-  
rupts weeds and aerates the upper crust  
of soil.  
2. Do not till deeper than 1"-2" to avoid  
injuring nearby plant roots. Cultivate  
often, so that weeds do not grow large  
3. Start the engine (see Stopping and  
Starting the Engine on the previous  
page). Stand behind the handlebar and  
push down on the handlebar to raise the  
tines off the ground. Squeeze the

lease the Throttle/Tines Lever to return to  
idle, the tines should stop rotating or they  
may rotate very slowly. Lowering them  
back to the ground should stop any  
rotation.  
3. With careful planning, you can space  
the seed rows far enough apart to allow  
sufficient room for the machine to culti-  
vate after the plants have grown.  
NOTE: For small gardens, overlap by  
one-half (1/2) the machine width, fol-  
lowed by successive passes at one-  
quarter (1/4) machine width. This over-  
lapping method assures thorough tilling.  
ADJUSTING TINE POSITIONS  
Depending upon the tilling project, you  
have a choice of three tine patterns:  
NOTE: If tines continue to rotate when  
engine is idling, either the idle speed is  
too high or the centrifugal clutch is mal-  
functioning. If this occurs, contact the  
Factory or your local authorized dealer.  
Wide (Standard) Tine Positions As  
shipped from the factory, the unit is set  
up for general tilling and cultivating. This  
10" wide tine pattern (the maximum tilling  
width) uses all four tine sections  
(A, Figure 7). See Tine Removal and In-  
stallation in Section 5 for detailed informa-  
tion on how to set up this tine position.  
4. Squeeze the Throttle/Tines Lever to  
start the tines rotating. Lower the tines to  
begin tilling. Firmly hold the handlebar to  
prevent the machine from moving for-  
ward too quickly and to allow enough  
time for the tines to dig deeply enough.

Section 5: Maintenance  
WARNING  
Before inspecting, cleaning or servicing the machine, shut off engine, wait for moving parts to stop, dis-  
connect spark plug wire and move wire away from spark plug.  
Failure to follow these instructions can result in serious personal injury or property damage.  
ENGINE MAINTENANCE  
WARNING  
WARNING  
The temperature of the muffler and adja-  
cent engine areas may exceed 150oF  
(65oC). Contact may cause burns. Avoid  
these areas. Remove the spark plug  
lead and ground the lead to the engine to  
prevent accidental starts and fires.  
Avoid contact with the cutting edges on  
the tines.  
B
To avoid personal injury when removing  
or installing tines, wear heavy work  
gloves. The engine must be off, all  
moving parts stopped, and the spark  
plug wire disconnected from the spark  
plug and moved away from the plug.  
Figure 13: Narrow tilling tine configuration.  
Failure to do this could cause personal  
injury.  
ARRANGING TINES FOR STONY SOIL  
1. Prop the machine forward so it rests  
on the front of the tubular carrying  
handle. The work surface should be flat  
and firm.  
ARRANGING TINES FOR NARROW  
TILLING  
1. Prop the machine forward so it rests  
on the front of the tubular carrying  
handle. The work surface should be flat  
and firm.  
Maintain the correct engine oil level and  
change the oil as recommended (more  
often in dusty conditions).  
Keep the air filter clean. Operating the  
engine with a dirty, clogged air filter can  
cause poor performance and damage to  
the engine. Never operate engine  
without air filter installed.  
2. Remove the ring lock pin (A, Figure 12)  
from both sides of the unit. Remove both  
outer tine sections. Be sure to mark each  
section as a left or right side tine and  
whether it is an inner or outer section.  
2. Flip open the ring (A, Figure 12) on the  
left side ring lock pin and remove the ring  
lock pin.  
Keep the spark plug clean and properly  
gapped. Replace every 2 years.  
3. Remove the inner tine sections and  
swap their positions (the inner right-side  
section goes onto the left side of the ma-  
chine, and the inner left-side goes onto  
the right side of the machine).  
IMPORTANT: The ring lock pin (A, Figure  
12) is under spring tension use care  
when removing or replacing the ring lock  
pin.  
WARNING  
Do not tamper with the engine governor  
screw which is factory-set for the proper  
engine speed. Overspeeding the engine  
beyond the factory high speed setting  
can be dangerous and will void the  
engine warranty. Authorized service  
shall be sought if a problem exists.  
A
The engine cooling fins must be kept  
clean to prevent overheating of the  
engine.  
If the engine is equipped with a spark  
arrester, clean it every year.  
Figure 14: Stony soil tine pattern.  
Figure 12: Standard wide tine pattern and  
ring lock pin location.  
Clean, check or adjust the following  
items according to the instructions in  
the Engine Owners Manual: fuel tank,  
fuel filter, clutch shoes, idle speed, valve  
clearance and fuel tubes.  
4. Reinstall the two outer tine sections  
onto the sides from which they were re-  
moved (Figure 14).  
3. Remove the outer tine section (do not  
remove inner tine section) and mark it as  
to which side it is from (left or right) and  
whether its an outer or inner tine section.  
5. Insert the ring lock pins through the  
rounded side of the tine shafts and snap  
the rings down over the shafts (see  
DETAIL - Ring Lock Pin, Figure 10, in  
Section 4).  
4. Slide one of the long bushings (B,  
Figure 13), provided with the unit, onto  
the shaft. Insert the ring lock pin through  
the rounded side of the tine shaft and  
snap the ring down over the shaft (see  
DETAIL - Ring Lock Pin, Figure 10, in  
Section 4).  
TINE REMOVAL  
AND INSTALLATION  
The tines wear with use and should be re-  
placed if tilling takes longer than usual or  
if the soil does not mix thoroughly. In ad-  
dition to the standard 10" tilling width tine  
pattern, the tines can be arranged in a  
narrow, 41/2" tilling width pattern for  
smaller areas, and a special pattern for  
stony soil conditions.  
5. Repeat this procedure on the opposite  
side.

Section 5: Maintenance  
WARNING  
Before inspecting, cleaning or servicing the machine, shut off engine, wait for moving parts to stop, dis-  
connect spark plug wire and move wire away from spark plug.  
Failure to follow these instructions can result in serious personal injury or property damage.  
REPLACING WORN TINE SECTIONS  
OFF-SEASON STORAGE PROCEDURE  
STORAGE  
The tines are excessively worn if tilling  
takes much longer than before and soil is  
not being mixed thoroughly enough.  
Protect the engine and perform recom-  
mended engine maintenance by fol-  
lowing the engine storage instructions  
found in the separate Engine Owners  
Manual.  
WARNING  
Never store your equipment when there  
is fuel in the fuel tank.  
1. Prop the machine forward so it rests  
on the front of the tubular carrying  
handle. The work surface should be flat  
and firm.  
Never place your equipment near any  
source of sparks or open flame (such  
as from a hot water heater, a space  
heater or clothes dryer).  
NOTE: Be sure to protect the fuel lines,  
carburetor and fuel tank from gum de-  
posits by removing the fuel or by  
treating the fuel with a stabilizer. See  
Engine Owners Manual for more infor-  
mation.  
2. Remove the ring lock pin (A, Figure 12)  
from both sides of the unit. Remove the  
old tine sections and replace them with  
new tine sections. Refer to Figure 12 and  
the tine position shown in the Parts List  
for tine positioning details. Insert the ring  
lock pins through the rounded side of the  
tine shafts and snap the ring over the  
shaft (see DETAIL - Ring Lock Pin, Figure  
10, in Section 4).  
Failure to comply can result in serious  
personal injury or property damage.  
Remove tines. Clean all soil and debris  
from dust covers and tine shaft. Lubri-  
cate tine shaft with light oil. Replace  
tines.  
IMPORTANT: It is important to prevent  
gum deposits from forming in essential  
fuel system parts such as carburetor, fuel  
filter, fuel hose, or tank during storage.  
Also, experience indicates that alcohol-  
blended fuels (called gasohol or 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.  
Cover engine and store equipment in a  
dry, sheltered location.  
TROUBLESHOOTING  
Before performing any of the corrections in this Troubleshooting Chart, refer to the appropriate information contained in this Manual
