TILLER SAFETY
IMPORTANT SAFETY INFORMATION
Most accidents with this product can be prevented if you follow all instructions in this manual and on the
product. The most common hazards, according to accident statistics, are discussed below, along with the
best way to protect yourself and others.
Honda Tiller Usage
Honda tillers are designed to give safe and dependable service if operated according to instructions and
intended use.
Honda tillers are intended to be used by an experienced, trained, operator who is familiar with the use of
power equipment. Do not allow a child or an inexperienced, untrained operator to use this tiller. Operating
this equipment requires special effort on your part to ensure your safety and the safety of others. Read and
understand this owner’s manual.
Avoid Rotating Tines
The rotating tines can cause injury. Keep away from the tine shield whenever the engine is running. If you
need to adjust the tines or work around the tines for any reason, always stop the engine. Disconnect the
spark plug cap if you need to clean or handle the tines.
Clear Tilling Area
The tiller tines can throw rocks and other objects with enough force to cause injury. Before tilling, carefully
inspect the area and remove all large debris.
Keep Shields in Place
Guards and shields are designed to protect you from being hit by thrown objects. They also help protect
you from hot engine parts and moving components. For your safety and the safety of others, keep all
guards and shields in place when operating the tiller.
Refuel with Care
Gasoline is extremely flammable and gasoline vapor can explode. Refuel only outdoors, in a
well-ventilated area, with the engine off. Never smoke near gasoline, and keep other flames and sparks
away. Always store gasoline in an approved container.
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 will help protect your feet and give you
better traction on slopes or uneven ground. Clothing worn by the operator should be close-fitting. Loose
clothing should not be permitted because it may get caught in moving parts. Tie up or restrain long hair.
Turn Engine Off When Not Tilling
If you need to leave the tiller for any reason, even just to inspect the area ahead, always stop the engine.

FG100 TILLER
TILLER SAFETY
ATTACHMENTS AND MODIFICATIONS
Do not make any modifications to your tiller. Modifying your tiller, or installing non-Honda attachments, can
make your tiller unsafe.
If you need attachments for your tiller, use only genuine Honda attachments. These products have been
designed for your tiller and are covered by the Accessories, Replacement & Parts and Appeal Warranty
(Page 41).
Non-Honda attachments are usually designed for universal applications. Although aftermarket attachments
may fit on your tiller, they may not meet factory specifications and could make your tiller unsafe.
IMPORTANT MESSAGE TO EMPLOYERS
As an employer, you have special responsibilities to the people who work for you.
Before you ask anyone to operate this tiller, you need to determine whether the person is old enough,
large enough, and strong enough to safely handle and control the tiller.
If you decide the person is, make sure the employee reads and understands all instructions and warnings
in this manual, and on the labels before operating the tiller.
Allow adequate time for hands-on training by a qualified instructor, and personally supervise practice
sessions until you feel sure the employee is ready to operate the tiller.
Also be sure employees wear proper clothing and have eye protection and any other gear that may be
required by local ordinances or your insurance company.
Remember, too, that you are responsible for keeping the tiller properly maintained and in safe operating
condition.
Your commitment to safety on the job can help prevent accidents and result in longer and more productive
years of service.
IMPORTANT MESSAGE TO PARENTS
Your child’s safety is very important to Honda. Read this message if you decide to permit your youngster to
operate this tiller. Tillers are tools, not toys. As with any equipment, bad judgments can result in serious
injuries. You can prevent accidents by making good decisions about if, when, and how your youngster
operates this equipment.
The first question you’ll need to ask is whether your youngster is capable of operating this tiller safely.
Remember, young people vary widely, and AGE IS NOT THE ONLY FACTOR. Physically, a youngster
must be LARGE ENOUGH AND STRONG ENOUGH to easily start the tiller and control its direction. The
youngster also needs enough size, strength, and coordination to comfortably reach and operate the controls.
Another, tougher question you need to ask is if your youngster has enough MATURITY AND
RESPONSIBILITY to safely operate this tiller. Does the young person think through problems and come to
logical solutions? Be honest! Anyone who takes unnecessary risks and doesn’t obey rules should not
operate this tiller.
If you decide that your son or daughter can handle the tiller safely, carefully read the owner’s manual with
your youngster. Make sure you both understand all instructions and safety information. Also, be sure your
youngster wears sturdy shoes and other protective clothing when operating or handling the tiller.
SUPERVISION is also very important. Walk with your youngster during the first few minutes of tilling. Even
after the youngster has become confident with the tiller, do not let the young person use the tiller without
good adult supervision. An adult should also be present during refueling and maintenance. In fact, it’s up
to the parents to make sure the tiller is properly maintained and kept in safe operating condition.
By always placing safety first, your youngster will acquire useful skills and a sense of accomplishment. And
you’ll both get the best results from your tiller.

CONTROLS
DESCRIPTION OF CONTROLS
ENGINE SWITCH
Throttle Lever
The throttle lever controls engine speed and tiller
tine rotation.
Pulling the throttle lever towards the grip increases
the engine speed which causes the tines to turn.
Releasing the throttle lever reduces engine speed
and stops the tiller tines from turning.
The tiller will have the greatest tilling force at
maximum engine speed. At idle, the tilling tines
should stop rotating.
THROTTLE LEVER
Engine Switch
The engine switch controls the ignition system.
The engine switch must be in the ON position for
the engine to start and run. Moving the engine
switch to the OFF position stops the engine.
Choke Lever
PRIMIMG
BULB
The choke lever opens and closes the choke valve
in the carburetor.
The CLOSED position enriches the fuel mixture for
starting a cold engine. The OPEN position
provides the correct fuel mixture for operation after
starting, and for restarting a warm engine.
Priming Bulb
Pressing the priming bulb pumps fuel from the fuel
tank to the carburetor. This procedure is necessary
for starting a cold engine and after refueling an
engine that has run out of fuel.
To ensure that fuel has reached the carburetor,
press the priming bulb repeatedly until fuel can be
seen in the clear-plastic fuel-return tube.

FG100 TILLER
BEFORE OPERATION
IS YOUR WORKING AREA READY?
Objects thrown by the tiller can cause serious injury. Be especially careful when crossing gravel drives,
walks or roads. Before operating the tiller, carefully inspect the area, and remove all objects that could be
thrown by, or entangled in, the tilling attachment, such as rocks, broken glass, nails, wire, or string.
Never operate the tiller without good visibility or light.
Clear the area of children, bystanders, and pets. Keep all children, bystanders, and pets at least
50 feet (15 meters) away from where the tiller is being operated.
If anyone approaches you while you are operating the tiller, release the throttle lever and stop the engine.
IS YOUR TILLER READY TO GO?
For your safety, and to maximize the service life of your equipment, it is very important to take a few
moments before you operate the tiller to check its condition. Be sure to take care of any problem you find,
or have your servicing dealer correct it, before you operate the tiller.
B WARNING
Improperly maintaining this tiller, or failing to correct a problem
before operation, could cause a malfunction in which you could be
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.
Tiller Tine Inspection
• Look for signs of damage to the tilling tines (or any accessory installed). Replace any tiller tines and
parts that are worn out, bent, cracked, chipped, or damaged in any way.
• Make sure the tiller accessory is properly installed and securely fastened (see attachment installation
instructions).
• Check that the debris shield is securely installed and in good condition.
Maintenance Inspection
Check the oil level (see page 19). Running the engine with a low oil level can cause engine damage.
Check the air filter (see page 20). A dirty air filter will restrict air flow to the carburetor, reducing engine
and tiller performance.
Check throttle operation (see page 24). The throttle must operate smoothly for good throttle control.
Check the fuel level (see page 25). Starting with a full tank will help to eliminate or reduce operating
interruptions for refueling.
FG100 TILLER

OPERATION
SAFETY PRECAUTIONS
Before operating the tiller for the first time, please review the IMPORTANT SAFETY INFORMATION (see
page 4) and the chapter titled BEFORE OPERATION (see page 10).
Even if you have operated other tillers, take time to become familiar with the operation of this tiller’s
controls and handling.
For your safety, avoid starting or operating the engine in an enclosed area, such as a garage. Your
engine’s exhaust contains poisonous carbon monoxide gas which 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.

OPERATION
TILLER OPERATION
1. Install the drag bar (see page 12). Honda recommends using the drag bar when tilling. The tiller can be
difficult to control without the drag bar installed.
2. Adjust the handlebar to a comfortable position around waist height for normal tilling (see page 12).
3. Set the tilling depth by moving the drag bar up or down (see page 12).
The ideal height of the drag bar will depend on the type of soil being tilled, and soil conditions at the
time of tilling. In general, however, the drag bar should be adjusted so that the tiller is tilted slightly
backward.
4. Start the engine (see page 13).
5. Tilt the tiller back until the tines are off the ground. Squeeze the throttle lever to full speed position
(lever tight against the grip).
6. Lower the front of the tiller until the tines begin to dig into the ground.
7. Lower the handle slightly so the front of the tiller is raised about 6 - 8°. To get the maximum advantage
from the tiller, hold the tiller at this angle while you are tilling the ground.

Handling Tips
• If the tiller tends to move forward rapidly, push down on the handlebars to allow the drag bar to
penetrate the soil and slow the forward motion of the tiller. Continue to press down until the tiller tines
have dug to a desired depth that allows easy tiller handling.
• If the tines dig in but the tiller will not move forward, ease up on the handlebars and move the
handlebars from side-to-side. If the tiller still digs in, but will not move forward, raise the drag bar up a
hole.
• When turning, push down on the handlebars to bring the tiller’s weight to the rear; this will make turning
easier.

LEVEL
If the fuel level is low, refuel in a well-ventilated
area with the engine stopped. If the engine has
been running, allow it to cool first.
To refuel, set the tiller on level ground. Remove
the fuel tank cap, and fill the tank with gasoline to
the bottom of the filler neck. Refuel carefully to
avoid spilling fuel. Do not overfill. There should not
be fuel in the filler neck. After refueling, tighten the
fuel tank cap securely.
B WARNING
Gasoline is highly flammable and explosive.
You can be burned or seriously injured when
handling fuel.
• Stop the engine and keep heat, sparks, and
flames away.
• Handle fuel only outdoors.
• Wipe up spills immediately.
Never refuel the engine inside a building where
gasoline fumes may reach flames or sparks. Keep
gasoline away from appliance pilot lights,
barbecues, electric appliances, power tools, etc.
Spilled fuel is not only a fire hazard, it causes
environmental damage. Wipe up spills immediately.
Move at least 10 feet (3 meters) away from the
fueling source location before starting the engine.

Fuel Recommendations
Use unleaded gasoline with a pump octane rating of
86 or higher.
This engine is certified to operate on unleaded
gasoline. Unleaded gasoline produces fewer engine
and spark plug deposits and extends exhaust
system life.
Never use stale or contaminated gasoline or an
oil/gasoline mixture. Avoid getting dirt or water in the
fuel tank.
Occasionally you may hear a light “spark knock” or
“pinging” (metallic rapping noise) while operating
under heavy loads. This is no cause for concern.
If spark knock or pinging occurs at a steady engine
speed, under normal load, change brands of
gasoline. If spark knock or pinging persists, see an
authorized Honda servicing dealer.
NOTICE
Running the engine with persistent spark knock or
pinging can cause engine damage.
Running the engine with persistent spark knock or
pinging is misuse, and the Distributor’s Limited
Warranty does not cover parts damaged by misuse.

STORAGE
Proper storage preparation is essential for keeping
your tiller troublefree and looking good. The
following steps will help to keep rust and corrosion
from impairing your tiller’s function and
appearance, and will make the engine easier to
start when you use the tiller again.
Cleaning
Wash the tiller, including the area around the tiller
tines.
Wash the engine by hand, and be careful to
prevent water from entering the air cleaner.
NOTICE
Using a garden hose or pressure washing
equipment can force water into the air cleaner.
Water in the air cleaner will soak the filter and can
enter the carburetor or engine, causing damage.
34
Water on a hot engine can cause damage. If the
engine has been running, allow it to cool for at least
1/2 hour before washing.
If using a garden hose or pressure washing
equipment to clean the tiller, be careful to avoid
getting water into controls and cables, or anywhere
near the engine air cleaner or muffler opening.
After washing the tiller, wipe dry all accessible
surfaces.
Start the engine outdoors, and let it run until it
reaches normal operating temperature to evaporate
any water remaining on the engine.
Stop the engine and allow it to cool.
After the tiller is clean and dry, touch up any
damaged paint, and coat other areas that may rust
with a light film of oil. Lubricate the throttle cable
core with a silicone spray lubricant.

TRANSPORTING/STORAGE
Fuel
Gasoline will oxidize and deteriorate in storage.
Old gasoline will cause hard starting, and it leaves
gum deposits that restrict 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, 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 Distributors Limited Warranty does not cover fuel
system damage or engine performance problems
resulting from neglected storage preparation.
Adding Fuel Stabilizer To Extend Fuel Storage
Life
Draining the Fuel Tank and Carburetor
Drain the fuel from the fuel tank to a suitable container
(see page 26).
Start the engine (see page13) and allow it to run
until the engine stops.
B WARNING
Gasoline is highly flammable and explosive.
You can be burned or seriously injured when
handling fuel.
• Stop the engine and keep heat, sparks, and
flames away.
• Handle fuel only outdoors.
• Wipe up spills immediately.
Engine Oil
Change the engine oil (see page 19).
Carburetor & Air Cleaner
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.
Clean the air filter (see page 21) and move the
choke lever to the CLOSED (E) position.
When adding a fuel stabilizer, fill the fuel tank with
fresh gasoline. If only partially filled, air in the tank
will promote fuel deterioration during storage. If
you keep a container of gasoline for refueling, be
sure that it contains only fresh gasoline. Add fuel
stabilizer following the manufacturer’s instructions.
Remove the spark plug (see page 22). Pour a
1/4 tablespoon (1 ~ 3 cc) of clean engine oil into the
cylinder. Pull the starter rope several times to
distribute the oil in the cylinder. Reinstall the spark
plug. Pull the starter rope slowly until resistance is
felt then return the starter grip gently. This closes
the valves so moisture cannot enter.
After adding a fuel stabilizer, run the engine
outdoors for 10 minutes to be sure that treated
gasoline has replaced the untreated gasoline in the
carburetor.

TRANSPORTING/STORAGE
STORAGE PRECAUTIONS
REMOVAL FROM STORAGE
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.
Check your tiller as described in the BEFORE
OPERATION chapter of this manual (see page 10).
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 possible, avoid storage areas with high humidity,
because that promotes rust and corrosion.
If the cylinder was coated with oil during storage
preparation, the engine will smoke briefly at startup.
This is normal.
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, promoting rust
and corrosion.

TECHNICAL & CONSUMER INFORMATION
OXYGENATED FUELS
Some conventional gasolines are being blended with alcohol or an ether compound. These gasolines are
collectively referred to as oxygenated fuels. To meet clean air standards, some areas of the USA and
Canada use oxygenated fuels to help reduce emissions. If you use an oxygenated fuel, be sure it is
unleaded and meets the minimum octane rating requirement. Before using an oxygenated fuel, try to
confirm the fuel’s contents. Some states/provinces require this information to be posted on the pump.
The following are the EPA approved percentages of oxygenates:
ETHANOL -------- (ethyl or grain alcohol) 10% by volume
You may use gasoline containing up to 10% ethanol by volume. Gasoline containing
ethanol may be marketed under the name “Gasohol.”
MTBE --------------- (Methyl Tertiary Butyl Ether) 15% by volume
You may use gasoline containing up to 15% MTBE by volume.
METHANOL ------ (methyl or wood alcohol) 5% by volume
You may use gasoline containing up to 5% methanol by volume, as long as it also
contains cosolvents and corrosion inhibitors to protect the fuel system. Gasoline
containing more than 5% methanol by volume may cause starting and/or performance
problems. It may also damage metal, rubber, and plastic parts of your fuel system.
If you notice any undesirable operating symptoms, try another service station, or switch to another brand of
gasoline. Fuel system damage or performance problems resulting from the use of an oxygenated fuel
containing more than the percentages of oxygenates mentioned above are not covered under warranty.
CARBURETOR MODIFICATIONS FOR HIGH ALTITUDE OPERATION
At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will decrease, and
fuel consumption will increase. A very rich mixture will also foul the spark plug and cause hard starting.
Operation at an altitude that differs from that at which this engine was certified, for extended periods of
time, may increase emissions.
High altitude performance can be improved by specific modifications to the carburetor. If you always
operate your tiller at altitudes above 5,000 feet (1,500 meters), have your servicing dealer perform this
carburetor modification. This engine, when operated at high altitude, with carburetor modifications for high
altitude use, will meet each emission standard throughout its useful life.
Even with carburetor modification, engine horsepower will decrease about 3.5% for each 1,000-foot
(300-meter) increase in altitude. The effect of altitude on horsepower will be greater than this if no
carburetor modification is made.
NOTICE
When the carburetor has been modified for high altitude operation, the air-fuel mixture will be too lean for
Iow altitude use. Operation at altitudes below 5,000 feet (1,500 meters) with a modified carburetor may
cause the engine to overheat and result in serious engine damage. For use at Iow altitudes, have your
servicing dealer return the carburetor to original factory specifications.

TECHNICAL & CONSUMER INFORMATION
EMISSION CONTROL SYSTEM INFORMATION
Source of Emissions
The combustion process produces carbon monoxide, oxides of nitrogen, and hydrocarbons. Control of hydrocarbons
and oxides of nitrogen is very important because, under certain conditions, they react to form photochemical smog
when subjected to sunlight. Carbon monoxide does not react in the same way, but it is toxic.
Honda utilizes lean carburetor settings and other systems to reduce the emissions of carbon monoxide, oxides of
nitrogen, and hydrocarbons.
The U.S and California Clean Air Acts
EPA and California regulations require all manufacturers to furnish written instructions describing the operation and
maintenance of emission control systems.
The following instructions and procedures must be followed in order to keep the emissions from your Honda engine
within the emission standards.
Tampering and Altering
Tampering with or altering the emission control system may increase emissions beyond the legal limit. Among those
acts that constitute tampering are:
•
Removal or alteration of any part of the intake, fuel, or exhaust systems.
•
Altering or defeating the governor linkage or speed-adjusting mechanism to cause the engine to operate outside
its design parameters.
Problems that may Affect Emissions
If you are aware of any of the following symptoms, have your engine inspected and repaired by your
servicing dealer.
•
Hard starting or stalling after starting.
•
Rough idle.
•
Misfiring or backfiring under load.
•
Afterburning (backfiring).
•
Black exhaust smoke or high fuel consumption.
Replacement Parts
The emission control systems on your new Honda engine were designed, built, and certified to conform with EPA and
California emission regulations. We recommend the use of genuine Honda parts whenever you have maintenance
done. These original-design replacement parts are manufactured to the same standards as the original parts, so you
can be confident of their performance. The use of replacement parts that are not of the original design and quality may
impair the effectiveness of your emission control system.
A manufacturer of an aftermarket part assumes the responsibility that the part will not adversely affect emission
performance. The manufacturer or rebuilder of the part must certify that use of the part will not result in a failure of the
engine to comply with emission regulations.
Maintenance
Follow the maintenance schedule on page 18. Remember that this schedule is based on the assumption that your
machine will be used for its designed purpose. Sustained high-load or high-temperature operation, or use in unusually
wet or dusty conditions, will require more frequent service.
