SAFETY INFORMATION Most accidents with snowblowers can be prevented if you follow all instructions in this manual and on the snowblower. The most common hazards are discussed below, along with the best way to protect yourself and others. Always make a pre-operation check (pages 14 thru 18 ) before you start the engine. You may prevent an accident or equipment damage. Honda snowblowers are designed to give safe and dependable service if operated according to instructions.
l l l l l l 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 avoid injury from flying debris and contact with the snowblower. to 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.

CONTROLS Engine Switch Use the engine switch to STOP the engine. to turn the ignition system ON for starting, and ENGINE SWITCH Fuel Valve The fuel valve opens and closes the fuel line leading from the fuel tank to the carburetor. Make sure that the valve is positioned exactly at either the ON or OFF position. When the snowblower is not in use, always leave the fuel valve in the OFF position to reduce the possibility of fuel leakage.
Choke Lever Close the choke when the engine is cold or difficult to start. Starter Grip See page 19 for starting procedures. Pull this grip to start the engine.

Chute Guide The chute guide controls the snow discharge angle and direction. CHUTE GUIDE CHUTE GUIDE Drive Clutch Lever Use the drive clutch lever to propel or stop the snowblower.
Auger Clutch Lever Squeezing the auger clutch lever also operates the drive clutch lever; the snowblowing mechanism starts and the snowblower moves forward. Releasing the auger clutch lever stops both the snowblowing mechanism and the forward motion of the snowblower.

To change handlebar height, remove the right and left adjusting bolts, align the bolt holes for the desired handlebar height, and reinstall the bolts. Tighten the nuts securely.
Engine Oil Inspection With the snowblower on a level surface, remove the oil filler cap and wipe the dipstick clean. Insert the dipstick into the filler neck, but do not screw it in. Remove the dipstick and check the oil level.

Fuel Refueling Fuel tank capacity: 3.5 0 (0.92 US gal, 0.77 Imp gal) Check the fuel level gauge, and refill the tank if the fuel level is low. Gasoline is highly flammable and explosive. You can be burned or seriously injured when handling fuel. l l l Stop the engine and keep heat, sparks, and flames away. Handle fuel only outdoors. Wipe up spills immediately. Refuel in a well-ventilated area before starting the engine. If the engine has been running, allow it to cool.
Fuel Recommendations Use unleaded gasoline with a pump octane rating of 86 or higher. This engine is desi ned to operate on unleaded gasoline. Unleaded gasoline produces Pewer engine and spark plug deposits and extends exhaust system life. Never use stale or contaminated gasoline Avoid getting dirt or water in the fuel tank. or an oil/gasoline mixture. hear a light “spark knock” or “pinging” Occasionally you ma (metallic rapping noise Y while operating under heavy loads. This is no cause for concern.
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 minimum octane rating requirement. and meets the Before using an oxygenated fuel, try to confirm the fuel’s contents.
Auger Bolts Check the auger for loose or broken bol,ts. If broken, new ones (page 39 ). replace them with NUT AUGER SHEAR BOLT Other Checks 1. Check all bolts, nuts and other fasteners for security. 2. Check each part for operation. 3.Check the entire machine for any other been caused in previous operation.

Stay clear of the snow discharge chute while the engine is running. If the snow discharge chute becomes clogged, stop the engine and use a wooden stick to unclog it.
Clearing Snow For best efficiency, clear snow before it melts, refreezes, and hardens. Do not use the throttle lever to adjust your forward speed. The throttle lever must remain in the FAST position for good snow-clearing performance. Tips for clearing deep or hard-packed l Clear narrow snow widths.

l l Clear with back-and-forth motions If the snow is so hard that the snowblower tends to ride over the surface, move it back and forth to remove snow gradually. Clear in layers If the height of the snow is greater than the height of snowblowing mechanism, remove it in several layers as shown.
High Altitude Operation At high altitude, the standard 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 snowblower at altitudes above 6,000 feet (1,800 meters), have your servicing dealer perform this carburetor modification.
