SNOWBLOWER
SAFETY
Keep Shields in Place
Guards and shields are designed to protect you from being hit by thrown
objectsand 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.
Adjust the snow discharge chute to avoid hitting the operator, bystanders,
windows, and other objects with ejected snow. Stay clear of the snow
discharge chute while the engine is running.
Children and pets must be kept away from the area of operation to avoid injury
from flying debris and contact with the snowblower.
Refuel with Care
Gasoline
is
extremely flammable, and gasoline vapor can explode.
Allow
the
engine to cool if the snowblower has been in operation. Refuel only outdoors
in
a
well-ventilated area with the engine
OFF.
Never
fill
the fuel tank beyond
the maximum fill mark. Never smoke near gasoline, and keepother flames and
sparks away. Always store gasoline in an approved container.
Turn Engine
OFF
When Not Operating the Snowblower
If
you need to leave the snowblower for any reason, even just to inspect the
area ahead, always turn the engine
off.
Operation on Slopes
To
avoid overturning, be careful when changing the direction of the snowblower
while operating it on a slope.
Do
not use the snowblower
to
remove snow from
roofs. The snowblower may overturn on steep slopes if left unattended
causing injury to the operator
or
bystanders.

SNOWBLOWER SAFETY
Operating Conditions
Do
not use the snowblower when visibility is poor. Under conditions of poor
visibility, there is a greater risk of striking an obstacle or causing injury. Adjust
the snow discharge chute to avoid hitting passing bystanders or vehicles. Stay
clear of the snow discharge chute while the engine is running.
Operating Near Roads
Always watch for vehicle traffic when operating the snowblower near roads
and driveways. Never operate the snowblower on public roads.
Operator Responsibility
Know how to stop the snowblower quickly in case of emergency. Understand
the use of all snowblower controls.
Never permit anyone to operate the snowblower without proper instruction.
Do
not let children operate the snowblower.
If
people or pets suddenly appear
in front of the snowblower while it is in operation, immediately release the
auger and drive clutch levers to stop the snowblower and avoid possible injury
from rotating auger blades.
While operating the snowblower, hold the handle firmly, and walk, don't run.
Wear suitable winter boots that resist slipping.

Objects
Anything which can be picked up by the augers and thrown is a potential
hazard to you and others. Look for things like stones, sticks, bones, nails, and
wire, and remove them from the work area.
People
and
Pets
People and animals near the work area can move into your snowblowers path
or into a position where they could be struck by thrown objects. Clear the area
of people, especially children and pets. Their safety is your responsibility.
Work Area
Check the condition of the snow. Adjust your snowblower ground speed (not
engine speed)
and
snowblowing swath accordingly.
Check the skid shoes for proper adjustment. Adjust the skid shoes to obtain
the auger ground clearance for the type of surface the snowblower will be

51).
20
OPERATION
SNOWBLOWING PRECAUTIONS
Before operating the snowblower for the first time, please review both the
SNOWBLOWER SAFETYchapter (page
5)
and the BEFORE OPERATION
chapter (page
18).
Even
if
you have operated other snowblowers, take time to become familiar
with how this snowblower works, and practice in a safe area until you build up
your skills.
Never tamper with, or alter any
of
the controls or safety devices on the
snowblower.
For your safety, avoid starting or operating the engine in an enclosed area
such as a garage. Your snowblower’s exhaust contains poisonous carbon
monoxide gas which can collect rapidly in an enclosed area and cause illness
or death.
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.

Operating tips for clearing hard or deep snow:
Reduce forward speed.
If
that is not sufficient, use the shift lever to clear
snow with a back and forth motion.
Clear a narrower swath. Make several passes with the auger overlapping
the cleared areas.
If
the snow is deeper than the height of the auger, remove it in several steps,
as shown below, or install
the drift-breaker
kit (optional part) that is available
from authorized Honda snowblower dealers.

SERVICING YOUR HONDA SNOWBLOWER
THE IMPORTANCE
OF
MAINTENANCE
Good maintenance is essential for safe, economical, and trouble-free operation.
It will also help reduce air pollution.
To help you properly care for your snowblower, the following pages include a
maintenanceschedule, routine inspection procedures, and simple maintenance
procedures using basic hand tools. Other service tasks that are more difficult,
or require special tools, are best handled by professionals and are normally
performed by a Honda technician or other qualified mechanic.
The maintenance schedule applies to normal operating conditions.
If
you
operate your snowblower under unusual conditions, consult your servicing
dealer for recommendations applicable to your individual needs and use.
Remember that your servicing dealer knows your snowblower best and is fully

MAINTENANCE SAFETY
Some of the most important safety precautions follow. However, we cannot
warn you of every conceivable hazard that can arise in performing maintenance.
Only you can decide whether or not you should perform a given task.
Failure to properly follow maintenance
instructions and precautions can cause
you to be seriously hurt or killed.
Always follow the procedures and
precautions in the owner’s manual.
Safety Precautions
Make sure the engine is off before you begin any maintenance or repairs.
This will eliminate several potential hazards:
-
Carbon monoxide poisoning from engine exhaust.
Be sure there is adequate ventilation whenever you operate the engine.
-
Burns from hot parts.
Let the engine and exhaust system cool before touching.
-
Injury from moving parts.
Do
not run the engine unless instructed to do
so.
Read the instructions before you begin, and make sure you have the tools
and skills required.
To
reduce the possibility of fire or explosion, be careful when working
around gasoline. Use only a nonflammable solvent, not gasoline, to clean
parts. Keepcigarettes, sparks, and flames away from all fuelre
-
lated parts.

FUEL RECOMMENDATIONS
Use unleaded gasoline with a pump octane rating of
86
or higher.
These engines are 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.
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 abuse.

Fuel
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 snowblower 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 deteriora-
tion. 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
Distributor’s Limited 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 fuel stabilizer that is formulated
for that purpose, or you can avoid fuel deterioration problems by draining the
fuel tank and carburetor.

Add fuel stabilizer following the manufacturer's instructions.
After adding a fuel stabilizer, run the engine outdoors for

STORAGE PRECAUTIONS
If
your snowblower 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 in the
OFF
position to reduce the possibility of fuel leakage.
Place the snowblower on a level surface. Tilting can cause fuel or oil leakage.
With the engine and exhaust system cool, cover the snowblower 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 engine, promoting rust and corrosion.
REMOVE FROM STORAGE
Check your snowblower as described in the
BEFORE
OfERATlONchapter
(page
18)
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.
I
If
the cylinder was coated with oil during storage preparation, the engine may
smoke briefly at startup. This is normal.

Carburetor Modification 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 a specific modifications to the
carburetor.
If
you always operate your pump 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 the 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.
LNOTlCE
I
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.

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 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
-
(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 containscosolvents 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.
Fuel system damage or performance problems resulting from the use of an
oxygenated fuel containing more than the percentages of oxygenates men-
tioned above are not covered under warranty.

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 impor-
tant 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 uses 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 Act
EPA and California regulations require all manufacturers to furnish written
instruction describing the operation and maintenance of emission control
systems.
The following instructions and procedures must be followed in order to keep
the Honda engine emissions within the emission standards.
Tampering and Altering
Tampering with or altering the emission control system may increase emis-
sions beyond the legal limit. Among those acts that constitute tampering are:
Removal or alteration of any part of intake, fuel, or exhaust system.
Altering or defeating the governor linkage or speed-adjusting mechanism
to cause the engine to operate outside its design parameters.
68

&
CONSUMER INFORMATION
Problems That May Affect
Emissions
If
you are aware of any of the following symptoms, have your engine inspected
and repaired by your authorized Honda servicing dealer.
Hard starting or stalling after starting.
Rough idle.
Misfiring or backfiring under load.
0
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 genuine Honda parts whenever you have mainte-
nance 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 afailure of the engine
-
to comply with emission regulations.
Maintenance
Follow the Maintenance Schedule on page
37.
Remember that this schedule
is based on the assumption that your machine will be used for its designed
purpose. Sustained high-load operation, will require more frequent service.
