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 and from hot engine parts and moving components. For your safety and the safety of others, keep all 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 fairly tight and belted. Loose clothing should not be permitted because of the danger of getting into 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 .

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 warranty.

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 they are, 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 important. Walk behind your youngster during the first few minutes of tilling. Even after the youngster is confident, do not let them use the tiller without supervision. An adult should also be present during refueling and maintenance. Be 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.

DESCRIPTION OF CONTROLS

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.

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.

THROTTLE LEVER

HANDLE BAR ADJUSTMENT (2-positions)

Handle Bar Adjustment

There are two positions that the handlebars can be adjusted to best suit the height of the operator.

Choke Lever

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.

BEFORE OPERATION

ARE YOU READY TO OPERATE THE TILLER?

Your safety is your responsibility. A little time spent in preparation will significantly reduce your risk of injury.

Knowledge

Read and understand this manual. Know what the controls do and how to operate them. Familiarize yourself with the tiller and its operation before you begin to use it. Know what to do in case of

emergencies.

Physical and Mental Readiness

You must be alert and in good physical condition to operate the tiller. Do not operate the tiller if you are tired, ill, or under the influence of alcohol, medication, or any substance that might impair your vision, dexterity, or judgment.

If you have any physical problem that may be aggravated by strenuous work, consult your physician before operating the tiller.

Protective Clothing

Wearing protective clothing will reduce your risk of injury. Do not wear loose clothing, jewelry, short pants, sandals, or go barefoot. Secure hair so it is above shoulder level.

Eye, Face, and Head Protection

Always wear safety glasses or goggles that comply with ANSI standard Z87.1 to protect your eyes from thrown objects. Prescription glasses may be worn under the safety glasses or goggles.

Wearing a dust mask will help to reduce the amount of pollens and dust inhaled.

Hearing Protection

Hearing protectors will help to protect your ears from noise. Earmuff-style hearing protectors can also protect your ears from thrown objects.

10 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 accessory operators

manual).

• 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 11

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 accessory), 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 (see page 12) (waist height for normal tilling operation).

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.

6 - 8°

• 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.

14 FG100 TILLER

Tilling In Rocky Soil

If you are tilling in stony or rocky soil, and experience continual rock jams between tines, set the tiller tines in the rocky soil pattern to help alleviate the problem.

1. Stop the engine (see page 13).

2. Disconnect the spark plug wire (see page 22).

3. Tip the tiller forward on the carrying handle as

shown.

4. Remove the lock pins from the left and right tine shafts by turning them UP [a] and pulling them OUT [b].

5. Clean the tine shafts.

6. Wearing heavy gloves, remove the tines. Note

thatthetinesetsarestamped“A”,“B”,“C”,and “D” just inside the raised inner area of the tine set.

7. Reinstall the tine sets in the rocky soil pattern shown. When reinstalling the tines, make sure the tine shaft and tine hubs are clean and free of foreign material. The tines should easily slide onto the shaft. Do not force the tines onto the shaft.

8. Install the lock pins throught the round side of the tine shaft hole [a], then turn it over [b] to lock it it in place.

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.

• 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 and site before starting the engine.

NOTICE

Fuel can damage paint and plastic. Be careful not to spill fuel when filling your fuel tank. Damage caused by spilled fuel is not covered under warranty.

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.

Secure the tiller by tying around the lower handles just in front and back of the engine as shown.

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

UPPER HANDLEBARS

TIE HERE

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.

TIE HERE

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.

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.

34 FG100 TILLER

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.

Draining the Fuel Tank and Carburetor

Drain the fuel from the fuel tank to a suitable container (see page 26).

Start the engine (see page 13) 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).

Adding fuel stabilizer to extend fuel storage life

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.

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.

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.

Carburetor & Air Cleaner

Clean the air filter (see page 21) and move the choke lever to the CLOSED (E) position.

Engine Cylinder

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.

FG100 TILLER 35

TRANSPORTING/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.

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.

REMOVAL FROM STORAGE

Check your tiller as described in the BEFORE OPERATION chapter (see page 10) of this manual. 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 will smoke briefly at startup. This is normal.

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.

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.

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 low 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 low 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.
