TILLER SAFETY
IMPORTANT SAFETY INFORMATION
Tillers are designed to cultivate earth outdoors. Other uses can result in
injury to the operator or damage to the tiller and other property.
Most injuries or property damage can be prevented if you follow all
instructions in this manual and on the tiller. The most common hazards are
discussed below, along with the best way to protect yourself and others.
Operator Responsibility
• Know how to stop the tiller quickly in case of emergency.
• Understand the use of all tiller controls.
• Keep a firm hold on the handlebars. They may tend to lift during clutch
engagement.
• Be sure the drag bar is in place and properly adjusted.
• Be sure that anyone who operates the tiller receives proper instruction.
Do not let children operate the tiller. Keep children and pets away from
the area of operation.
Carbon Monoxide Hazard
• Exhaust contains poisonous carbon monoxide, a colorless, odorless gas.
Breathing carbon monoxide can cause loss of consciousness and may
lead to death.
• If you run the tiller in a confined or even partially enclosed area, the air
you breathe could contain dangerous amounts of carbon monoxide. To
keep carbon monoxide from building up, provide adequate ventilation.
2
TILLER SAFETY
Fire and Burn Hazards
• The exhaust system gets hot enough to ignite some materials.
— Keep the tiller at least 3 feet (1 meter) away from buildings and other
equipment during operation.
— Keep flammable materials away from the tiller.
• The muffler becomes very hot during operation and remains hot for a
while after stopping the engine. Be careful not to touch the muffler while it
is hot. Let the engine cool before storing the tiller indoors.
Refuel With Care
Gasoline is extremely flammable, and gasoline vapor can explode. Allow the
engine to cool if the tiller has been in operation. Refuel only outdoors in a
well-ventilated area with the engine OFF. Do not overfill the fuel tank. Never
smoke near gasoline, and keep other flames and sparks away.
Always store gasoline in an approved container. Make sure that any spilled
fuel has been wiped up before starting the engine.
Avoid Rotating Tines
Rotating tines can cause serious cuts and even amputate body parts. Keep
away from the tine area whenever the engine is running. If you need to work
around the tines to clear object accumulation or for any other reason, always
shut off the engine. Disconnect the spark plug cap, and wear heavy gloves
when you need to clean the tine area or handle the tines.
Clear Tilling Area
A tine can throw rocks and other objects with enough force to cause serious
injury. Before tilling, carefully inspect the area and remove all stones, sticks,
bones, nails, pieces of wire, and other loose objects. Be aware if children are
in the area, stop the tiller. Never operate the tines over gravel.
3
TILLER SAFETY
Keep Shields in Place
Guards and shields are designed to protect you from being hit by thrown
objects and to keep you from touching hot engine parts and moving
components.
For your safety and the safety of others, keep all shields in place when the
engine is running.
Wear Protective Clothing
Wearing protective clothing will reduce your risk of injury. Long pants and
eye protection reduce the risk of injuries from thrown objects. Sturdy shoes
with aggressive soles provide better traction.
Turn the Engine Off When Not Operating the Tiller
If you need to leave the tiller for any reason, even just to inspect the area
ahead, always turn the engine off.
Slope Operation
• When tilling on slopes, keep the fuel tank less than half full to minimize
fuel spillage.
• Till across the slope (at equally spaced intervals) rather than up and down
it.
• Be very careful when changing the direction of the tiller on a slope.
• Do not use the tiller on a slope of more than 10°. Before starting the
engine, check that the tiller is not damaged and is in good condition. For
your safety and the safety of others, exercise extreme care when using
the tiller on a slope.
Tilling Conditions
Operate the tiller only in daylight or good artificial light. Do not operate the
tiller at night or under poor light conditions.

seriously injured.
Always perform a pre-operation
inspection before each operation,
and correct any problem.
Safety Inspection
Look around the engine for signs of oil or gasoline leaks. Wipe up any spills
before starting the engine.
Replace any damaged parts.
Check that all fasteners are in place and secure. Tighten as necessary.
9
BEFORE OPERATlON
Tiller Tine Inspection
Look for signs of damage to the tilling tines (or any necessary installed).
Replace any tiller tines and parts that are worn out, bent, cracked, chipped,
or damaged in any way.
When using an accessory, make sure it is properly installed and securely
fastened.
Check that the debris shield is securely installed and in good condition.
Maintenance inspection

or reduce operating interruptions for refueling.
10
OPERATION
SAFE OPERATING PRECAUTIONS
Before operating the tiller for the first time, please review both the TILLER
SAFETY chapter and the chapter titled BEFORE OPERATION.
For your safety, do not start or operate the tiller in an enclosed area such as
a garage. Your tiller’s exhaust contains poisonous carbon monoxide gas that
can collect rapidly in an enclosed area and cause illness or death.
If the tiller starts to shake or vibrate, stop the engine immediately. After the
tiller tines have completely stopped, inspect them to determine the cause of
the vibration. Sudden vibration is a sign of a hazardous problem, such as
loose or damaged tilling tines ( or tiller attachment), hidden objects in the
soil, or the ground that is too hard to till. Do not operate the tiller until the
problem is corrected.
Carbon monoxide gas is toxic.
Breathing it can cause
unconsciousness and even kill you.
Avoid any enclosed areas or
activities that expose you to carbon
monoxide.
STARTING THE ENGINE
Tines are sharp and spin fast.
Spinning tines can cut you severely
and can amputate body parts.
• Wear protective footwear.
• Keep your hands and feet away
from the tines while the engine is
running.
• Stop the engine before performing
any adjustment, inspection, or
maintenance.

Depending on the region where you operate your equipment, fuel formulations may
deteriorate and oxidize rapidly. Fuel deterioration and oxidation can occur in as little
as 30 days and may cause damage to the carburetor and/or fuel system. Please
check with your servicing dealer for local storage recommendations.
Gasoline will oxidize and deteriorate in storage. Old gasoline will cause hard
starting, and it leaves gum deposits that clog the fuel system. If the gasoline
in your tiller deteriorates during storage, you may need to have the
carburetor and other fuel system components serviced or replaced.
The length of time that gasoline can be left in your fuel tank and carburetor
without causing functional problems will vary with such factors as gasoline
blend, your storage temperatures, and whether the fuel tank is partially or
completely filled. The air in a partially filled fuel tank promotes fuel
deterioration. Very warm storage temperatures accelerate fuel deterioration.
Fuel deterioration problems may occur within a few months, or even less if
the gasoline was not fresh when you filled the fuel tank.
The Warranty does not cover fuel system damage or engine performance
problems resulting from neglected storage preparation.
You can extend fuel storage life by adding a gasoline stabilizer that is
formulated for that purpose, or you can avoid fuel deterioration problems by
draining the fuel tank and carburetor.
Adding a Gasoline Stabilizer to Extend Fuel Storage Life
When adding a gasoline stabilizer, fill the fuel tank with fresh gasoline. If only
partially filled, air in the tank will promote fuel deterioration during storage. If

STORAGE
you keep a container of gasoline for refueling, be sure that it contains only
fresh gasoline.
1. Add gasoline stabilizer following manufacturer’s instructions.
2. After adding a gasoline stabilizer, run the engine outdoors for 10 minutes
to be sure that treated gasoline has replaced the untreated gasoline in the
carburetor.
3. Stop the engine.
Draining the Fuel Tank and Carburetor
1. Place an approved gasoline container below the carburetor, and use a
funnel to avoid spilling fuel.
2. Loosen the carburetor drain screw.
Gasoline is highly flammable and
explosive.
You can be burned or seriously
injured when handling fuel.
• Stop the engine and keep heat,
sparks, and flame away.
• Refuel only outdoors.
• Wipe up spills immediately.

DRAIN SCREW
3. After all the fuel has drained into the container, tighten the drain screw
securely.
Engine Oil
1. Change the engine oil (see page 21).
2. Remove the spark plug (see page 25).
3. Pour a teaspoon (5 cc) of clean engine oil into the cylinder.
4. Gently pull the starter grip several times to distribute the oil in the cylinder.
5. Reinstall the spark plug and spark plug cap.
6. Pull the starter grip slowly until you feel resistance, and then return the
starter grip gently. This will close the valves so moisture cannot enter the
engine cylinder.

STORAGE
STORAGE PRECAUTIONS
If your tiller will be stored with gasoline in the fuel tank and carburetor, it is
important to reduce the hazard of gasoline vapor ignition. Select a well
ventilated storage area away from any appliance that operates with a flame,
such as a furnace, water heater, or clothes dryer. Also avoid any area with a
spark-producing electric motor, or where power tools are operated.
If possible, avoid storage areas with high humidity, because that promotes
rust and corrosion.
Unless all fuel has been drained from the fuel tank, leave the fuel valve
tightened enough to reduce the possibility of fuel leakage.
Place the tiller on a level surface. Tilting can cause fuel or oil leakage.
With the engine and exhaust system cool, cover the tiller to keep out dust. A
hot engine and exhaust system can ignite or melt some materials. Do not
use sheet plastic as a dust cover. A nonporous cover will trap moisture
around the tiller, promoting rust and corrosion.
REMOVAL FROM STORAGE
Check your tiller as described in the BEFORE OPERATlON chapter of this
manual (see page 8).
If the fuel was drained during storage preparation, fill the tank with fresh
gasoline. If you keep a container of gasoline for refueling, be sure that it
contains only fresh gasoline. Gasoline oxidizes and deteriorates over time,
causing hard starting.
If the cylinder was coated with oil during storage preparation, the engine may
smoke briefly at start-up. This is normal.
32
TRANSPORTING
BEFORE LOADING
If the engine has been running, allow it to cool for at least 15 minutes before
loading the tiller on the transport vehicle. A hot engine and exhaust system
can burn you and can ignite some materials.
LOADING AND UNLOADING
If a suitable loading ramp is not available, two people should lift the tiller on
and off the transport vehicle while holding the tiller level.
Position the tiller so it sits flat on the bed of the transport vehicle. Tie the tiller
down with rope or straps. Keep the tie-down rope or straps away from the
controls, adjustment levers, cables, and the carburetor.
