Object Hazard
Objects hit by the rotating tines can be thrown from the tiller with great force,
and may cause serious injury.
l
Before tilling, clear the tilling area of sticks, large stones, wire, glass, etc.
Till only in daylight.
l
Always inspect the tiller for damage after striking a foreign object. Repair
or replace any damaged parts before continuing use.
l
Pieces thrown from worn or damaged tines can cause serious injury.
Always inspect the tines before using the tiller.
5
Fire and Burn Hazard
6
Gasoline is extremely flammable, and gasoline vapor can explode. Use
extreme care when handling gasoline. Keep gasoline out of reach of children.
l
Refuel in a well-ventilated area with the engine stopped.
l
Allow the engine to cool before refueling. Fuel vapor or spilled fuel may
ignite.
l
The engine and the exhaust system become very hot during operation and
remain hot for a while after stopping. Contact with hot engine components
can cause burn injuries and can ignite some materials.
l
Avoid touching a hot engine or exhaust system.
l
Allow the engine to cool before performing maintenance or storing the tiller
indoors.
Carbon Monoxide Poisoning Hazard
Exhaust contains poisonous carbon monoxide, a colorless and odorless gas.
Breathing exhaust can cause loss of consciousness and may lead to death.
l
If yourun the engine in an area that is confined or even partially enclosed,
the air you breathe could contain a dangerous amount of exhaust gas. To
keep exhaust gas from building up, provide adequate ventilation.
Operation on a
l

Slope
spillage.
l
Till across the slope (At equally spaced intervals) rather than up and down
it.
l
Be very careful when changing the direction of the tiller on a slope.
l
Do not use the tiller on a slope of more than 10”.
The maximum safe grade angle shown is for reference purpose only and
should be determined according to the type of the soil. Before starting the
engine, check that the tiller is not damaged and in good condition. For your

ENGINE OIL
1. Place the tiller on a level surface.
2. Remove the oil filler cap and wipe the dipstick clean.
3. Insert the dipstick into the oil filler neck, but do not screw it in.
4. If the level is low, fill to the top of the oil filler neck with the recommended
oil.
Running the engine with a low oil level will cause serious engine
damage.
Use 4-stroke motor oil that meets or exceeds the requirements for API service
classification SF or SG. Always check the API SERVICE label on the container
to be sure it includes the letters SF or SG.
Using nondetergent oil can shorten the engine’s service life, and using
P-stroke oil will damage the engine.
SAE 1 OW-30 is recommended for general use. Other viscosities shown in the
following chart may be used when the average temperature in your area is
within the indicated range.

Refueling
Remove the fuel tank filler cap, and check if the fuel is up to the level mark.
If the fuel level is low, refill with regular gasoline up to the level mark.
Fuel tank capacity: 2.6 I? (0.69 US gal, 0.57 Imp gal)
Gasoline is highly flammable and explosive.
You can be burned or seriously injured when handling fuel.
l
Stop the engine and keep heat, sparks, and flames away.
l
Handle fuel only outdoors.
l
Wipe up spills immediately.
Refuel in a well-ventilated area before starting the engine. If the engine has
been running, allow it to cool. Refuel carefully to avoid spilling fuel. Do not fill
above the “LEVEL” mark in fuel strainer. After refueling, tighten the fuel tank
cap.
Never refuel the tiller 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
spills immediately.

LEVEL MARK
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.
1 NOTICE 1
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.
13
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 United States 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 -
MTBE (Methyl Tertiary Butyl Ether) 15% by volume
METHANOL -
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.
(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”.
You may use gasoline containing up to 15% MTBE by
volume.
(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.

4. STARTING THE ENGINE
Start the engine outdoors. If you run the engine in an area that is confined, or
even partially enclosed, the air can become contaminated with a dangerous
amount of exhaust gas.
Exhaust contains poisonous carbon monoxide, a colorless and odorless gas. Breathing exhaust can cause loss of consciousness and may
lead to death. To keep exhaust gas from building up, provide adequate
ventilation.
1. Turn the fuel valve lever to the ON
position.
