Add Fuel

This engine is certified to operate on regular gasoline with a pump 
octane rating of 86 or higher.

Never use stale or contaminated gasoline or an oil/gasoline mixture. 
Avoid getting dirt or water in the fuel tank.

You may use regular unleaded gasoline containing no more than 10% 
ethanol (E10) or 5% methanol by volume. In addition, methanol must 
contain cosolvents and corrosion inhibitors.

Use of fuels with content of ethanol or methanol greater than shown 
above may cause starting and/or performance problems. It may also 
damage metal, rubber, and plastic parts of the fuel system.

Engine damage or performance problems that result from using a fuel 
with percentages of ethanol or methanol greater than shown above 
are not covered under warranty.

NOTICE

If your equipment will be used on an infrequent or intermittent basis, 
(more than 4 weeks before next use), refer to “AVOIDING 
FUEL-RELATED PROBLEMS” on 

page 19

 for information regarding 

fuel deterioration.

1. Remove the fuel tank cap.
2. Add fuel to the shoulder of the filler neck. Do not overfill. Wipe up 

spilled fuel before starting the engine.

3. Tighten the fuel tank cap securely.

Move the snow blower 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 by the 

DISTRIBUTOR’S LIMITED WARRANTY

OPERATION

Honda snow blowers are designed to clear snow from driveways and 
walkways. Other uses can result in injury to the operator or damage to 
the snow blower and other property.
Most injuries and property damage with snow blowers can be 
prevented if you follow all instructions in this manual and on the snow 
blower. The most common hazards are discussed below, along with 
the best way to protect yourself and others.

Avoid Rotating Auger

The snow blower auger can cause serious cuts and even amputate 
fingers, hands, toes, or feet. Keep away from the auger whenever the 
engine is running. If you need to work around the snow blower to clear 
snow for any reason, always shut off the engine. If the snow 
discharge chute becomes clogged, stop the engine and disconnect 
the spark plug cap. Use a wooden stick to remove the obstruction. 
Never put your hand into the snow discharge chute while the engine is 
running; serious personal injury could result.

Clear Operation Area

The snow blower can throw rocks and other objects with enough force 
to cause serious injury. Before operating the snow blower, carefully 
inspect the area and remove all obvious hazards. Never use the snow 
blower to clear snow from a gravel road or driveway, as rocks may be 
picked up and ejected. They may cause injury to bystanders.

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.
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 snow blower.

Refuel with Care

Gasoline is extremely flammable, and gasoline vapor can explode. 
Allow the engine to cool if the snow blower 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 keep other flames and sparks away. Always store 
gasoline in an approved container.

Turn Engine Off When Not Operating the Snow Blower

If you need to leave the snow blower 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 
snow blower while operating it on a slope. Do not use the snow blower 
to remove snow from roofs. The snow blower may overturn on steep 
slopes if left unattended, causing injury to the operator or bystanders.
Do not operate on slopes greater than 20°.

 WARNING

Gasoline is highly flammable and explosive, and you can be 

burned or seriously injured when refueling.

 • Stop the engine and let it cool before refueling
 • Keep heat, sparks, and flame away
 • Refuel only outdoors
 • Wipe up spills immediately
