SAFE HANDLING OF GASOLINE

To avoid personal injury or property damage use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Serious personal injury can occur when gasoline is spilled on yourself or your clothes which can ignite, therefore wash your skin and change clothes immediately.

• Use only an approved gasoline container.
• Extinguish all cigarettes, cigars, pipes and other sources of ignition.
• Never fuel snow thrower unit's engine indoors.
• Never remove gas cap or add fuel while the engine is hot or running.
• Allow engine to cool at least two minutes before refueling.
• Never over fill fuel tank.
• Replace gasoline cap and tighten securely.
• If gasoline is spilled, wipe it off the engine and equipment. Move machine to another area. Wait 5 minutes before starting the engine.
• Never store the machine or fuel container inside where there is an open flame, spark or pilot light (e.g. furnace, water heats, space heater, clothes dryer etc.).
• Allow machine to cool at least 5 minutes before storing.
• Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before filling.
• If possible, remove gas-powered equipment from the truck or trailer and refuel it on the ground.
• If this is not possible, then refuel such equipment on a trailer with a portable container, rather than from a gasoline dispenser nozzle.
• Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock open device.

OPERATION

• Do not put hands or feet near rotating parts, in the auger impeller housing or chute assembly. Contact with the rotating parts can amputate hands and feet.
• The auger (impeller) control lever is a safety device. Never bypass its operation. Doing so makes the machine unsafe and may cause personal injury.
• The control levers must operate easily in both directions and automatically return to the disengaged (vertical) position when released.
• Never operate with a missing or damaged chute assembly. Keep all safety devices in place and working.
• Never run an engine indoors or in a poorly ventilated area. Engine exhaust contains carbon monoxide, an odorless and deadly gas.
• Do not operate machine while under the influence of alcohol or drugs.
• Muffler and engine become hot and can cause burning. Do not touch. Keep children away.
• Exercise extreme caution when operating on or crossing gravel surfaces. Stay alert for hidden hazards or traffic.
• Exercise caution when changing direction and while operating on slopes.
• Plan your snow-throwing pattern to avoid snow discharge towards windows, walls, cars etc., thus avoiding possible property damage or personal injury caused by a ricocheting debris.
• Never direct discharge at children, bystanders and pets or allow anyone in front of the machine.
• Do not overload machine capacity by attempting to clear snow at too fast of a rate....
  Remember! Slow and steady operation is best to avoid clogs of snow being impelled too rapidly.
• Never operate this machine without good visibility or light. Always be sure of your footing and keep a firm hold on the handles. Walk, never run.
• Disengage power to the auger system (auger/impeller) by releasing the auger control (lever) when transporting or not in use.
• Never operate machine at high transport speeds on slippery surfaces. Look down and behind and use care when backing up.
• If the machine should start to vibrate abnormally, stop the engine, disconnect the spark plug wire and ground it against the engine. Inspect thoroughly for damage. Repair any damage before starting and operating.
• Disengage all (drive and auger) control levers and stop engine before you leave the operation position (behind the handles).
• Wait until the auger /impeller comes to a complete stop before unclogging the chute assembly, making any adjustments or inspections.
• Never put your hand in the discharge or collector openings. Always use the clean-out tool provided to unclog the discharge opening. Do not unclog chute assembly while engine is running. Shut off engine and remain behind handles until all moving parts have stopped before unclogging.
• Use only attachments and accessories approved by the manufacturer (e.g. wheel weights, tire chains, cabs etc.).
• When staring engine, pull cord slowly until resistance is felt, then pull rapidly, Rapid retraction of starter cord (kickback) will pull hand and arm toward engine faster then you can let go. Broken bones, fractures, bruises or sprains could result.
• If situations occur which are not covered in this manual, use care and good judgment contact customer support for assistance.

MAINTENANCE & STORAGE

• Never tamper with safety devices. Check their proper operation regularly. Refer to the maintenance and adjustment sections of manual.
• Before cleaning, repairing, or inspecting machine disengage all control levers and stop the engine.
• Wait until the auger impeller comes to a complete stop. Disconnect the spark plug wire to prevent unintended starting.
• Check bolts and screws for proper tightness (EVERY TIME before & after use) as engine vibration could cause hardware to loosen...consider using a Loc-Tite product to keep hardware secure. This process will keep the machine in safe working condition. Also, visually inspect machine for any damage.
• Verify that the auger gearbox, located between your right and left auger blades, has substantial lubricant in the casing. The gearbox fill and drain plugs (bolts) are the only "vertical" plugs (bolts) on the gearbox assembly when viewed in the standing position. The top plug (bolt) is used for filling...the bottom plug (bolt) is for draining. Simply remove the top plug (bolt) for verification of lubricant, as it should be inside. To drain, simply remove bottom plug (bolt).
• Do not change the engine governor setting or overspeed the engine. The governor controls the maximum safe operating speed of the engine.
• Snow thrower auger belts, shave plates, shear pins and skid shoes are subject to wear and damage, therefore it is expected that the owner assume personal responsibility for the maintenance (removal & installation) of these items.
• For your safety protection, frequently check all components and replace with original equipment manufacturers (OEM) parts only. Use of parts which do not meet the original equipment specifications may lead to improper performance and compromise safety.
• Check (drive & auger) control lever (handles) and cables periodically to verify they engage and disengage properly and adjust, if necessary. Refer to the adjustment section in this operator's manual for instructions.
• Maintain or replace safety and instruction labels, as necessary.
• Observe proper disposal laws and regulations for gas, oil, etc. to protect the environment.
• Prior to storing, run machine a few minutes to clear snow from machine and prevent freeze up of auger impeller and completely wipe down unit, while inspecting for frozen components.
• Never store the machine or fuel container inside where there is an open flame, spark or pilot light such as water heater, furnace, clothes dryer etc.
• Always refer to the operator's manual for proper instructions on off-season storage. A YouTube video is available, which illustrates this process: https://www.youtube.com/watch?v=X4KYcFEfeY4
• Check fuel line, tank, cap and fittings frequently for cracks or leaks. Replace if necessary.
• Do not crank engine with spark plug removed.
• Have the machine inspected annually by an authorized service dealer to ensure that all mechanical and safety systems are working properly and have not worn excessively*. Failure to do so can result in accidents, injuries or death.

*Please note that an annual inspection is not covered within the warranty program...only REPAIR service.

CLEANING

1. To clean your Snow Thrower, use a damp cloth and mild detergent on the surfaces only. Never get soap or water inside the working mechanisms of your Snow Thrower. Do not clean with water. Water will freeze due to low temperature and damage the machine.
2. Clean the Snow Thrower of snow and ice buildup before storing or transporting. Be sure to secure the unit while transporting.
3. Inspect the Snow Thrower carefully for worn, loose, or damaged parts. Check connections and screws and tighten if necessary.

DO NOT MODIFY THE ENGINE

SNOW THROWER PREPARATION

ADD OIL

The snow thrower is shipped without oil. User must add the proper amount of oil before operating the snow blower for the first time. The oil capacity of the engine crankcase is 20.29 fl. oz. For general use, we recommend 5W-30, 4-stroke engine oil.

ENGINE OIL RECOMMENDATIONS

Select good quality detergent oil bearing the American Petroleum Institute (API) service classifications SJ, SL, or SM (synthetic oils may be used). Use the ASE viscosity grade of oil from the following chart that matches the starting temperature anticipated before the next oil changes.

To add oil, follow these steps:

1. Make sure the snow thrower is on a level surface. Tilting the snow thrower to assist in filling will cause oil to flow into engine areas and will cause damage. Keep snow thrower level!
2. Remove the dipstick from the engine.
   
3. Add oil slowly as to not overflow the unit.
4. To check the oil level, wipe the dipstick with a clean rag. Insert the dipstick into the oil fill opening without screwing it in. Remove the dipstick to check the oil mark.
5. Slowly add more oil and repeat step 4 until the oil mark reaches to the top of the dipstick. Do not overfill the crankcase.
6. Check for oil leaks. Tighten dipstick firmly.

ADD GASOLINE

Use fresh (within 30 days from purchase), lead-free gasoline with a minimum of 87 octane rating. Do not mix oil with gasoline.

To add gasoline, follow these steps:

1. Make sure the snow thrower is on a level surface.
2. Unscrew fuel tank cap and set aside. NOTE: The fuel cap may be tight and hard to unscrew.
3. Slowly add unleaded gasoline to the fuel tank. Be careful not to overfill. The capacity of the fuel tank is 0.5 gallons. NOTE: Do not fill the fuel tank to the very top. Gasoline will expand and spill over during use even with the fuel cap in place.
4. Reinstall fuel cap and wipe clean any spilled gasoline with a dry cloth.

• Never use an oil/gasoline mixture.
• Never use old gasoline.
• Avoid getting dirt or water into the fuel tank.
• Gasoline can age in the tank and make starting difficult. Never store snow thrower for extended periods of time with fuel in the tank or the carburetor.

NOTE: After completing the above preparation, the engine is ready to be started.

Keep the area of operation free from foreign objects that can be thrown by the auger and/or impeller blades. Perform a thorough inspection of the area since some objects may be hidden from view by surrounding snow. If the snow thrower hits an obstruction or picks up a foreign object during use, stop the snow thrower immediately, remove the obstruction, and inspect it for damage. Repair or replace any damaged parts before restarting and operating you snow thrower.

• Keep children, pets, and bystanders away from the area of operation. Be aware that the normal noise of the snow thrower when turned on may make it difficult for you to hear approaching people.
• Start your clearing path by throwing snow in a back and forth motion. To clear in the opposite direction, stop your snow thrower and pivot it on its' wheels to face the opposite direction. Make sure to overlap clearing paths.
• Determine the direction of the wind. If possible, move in the same direction as the wind so that the snow is not thrown against the wind, back into your face and on the just cleared path.

DO NOT USE YOUR HANDS TO UNCLOG CHUTE. Stop the motor before removing debris. Use the supplied Clean-out tool to unclog the chute. Do not walk in front of your running snow thrower. Do not direct discharged snow towards bystanders.

• Do not apply additional man-made load to the engine since this may damage the engine.
• Some parts of your snow thrower may freeze under extreme temperature conditions. Do not attempt to operate your snow thrower with frozen parts. If the parts freeze while your snow thrower is in use, stop the unit and inspect it for frozen parts. Thaw all parts before restarting and operating your snow thrower. Never force parts or controls that are frozen. Never use an open flame of any sort to thaw frozen parts.

Pre-Operation Inspection

Before using your snow thrower for the first time, check the following:

• Have you read and followed all setup and operation procedures for the engine as outlined?
• Has the engine been filled with oil and gasoline to the proper level?
• Are all snow thrower components properly attached and assembled?
• Are there any broken or damaged parts?
• Are all fasteners tight?
• Are the tires inflated to the proper pressure?

NOTICE: If you are unsure about the assembly or condition of any of your snow thrower parts, please call our customer service department at (800)791 9458.

AUGER AND DRIVE CONTROLS

1. To engage the auger (blades), press down on the auger control lever (left side handle).
2. To engage the drive, press down on the drive control lever (right side handle). The machine should start moving in the direction and speed for the respective setting on the speed/gear control.

When finished clearing a snow path, release the auger control lever (handle) and the drive control lever (handle)Attention: Release (disengage) the auger and drive control lever (handles) before adjusting the drive speed control lever. NEVER change the drive/gear speed while your snow thrower is in motion, as it will damage the drive mechanism and void the warranty.

DRIVE SPEED/GEAR CONTROL

Move the drive speed control lever to the desired speed. There are eight (8) settings: six (6) forward speeds and two (2) reverse speeds. 1 is the slowest forward speed and 6 is the fastest forward speed. R1 is the slowest reverse speed and R2 is the fastest reverse speed.

Note: There is no neutral drive setting since the drive control handle must be engaged for movement. Neutral is achieved when the drive control handle is disengaged.

CHUTE DISCHARGE DIRECTION ADJUSTMENT

Never direct the snow discharge chute at the operator, bystanders, vehicles, or nearby windows. Discharged snow and foreign objects accidentally picked up by the Snow Thrower can cause serious damage and severe bodily injury. Always point the discharge chute in the opposite direction from potential hazards. The discharge chute can be adjusted 180º by rotating the chute rotation handle. Rotate the chute rotation handle clockwise to move the discharge chute to the right; counterclockwise to move the chute to the left.

SKID SHOES ADJUSTMENT

Adjustment of the skid shoes sets the height above the ground at which the auger shave plate operates. For clearing snow from concrete, asphalt, and other smooth surfaces, set the auger shave plate so that the bottom of the plate is just above the ground.

For clearing snow from gravel, dirt, and other rough surfaces set the auger shave plate slightly above the ground to avoid dirt and gravel from entering the auger.

The optimal height of the plate will vary depending on the type of surface being cleared. Surfaces with larger gravel or stones require a higher shave plate setting.

1. Move the snow thrower to a solid, smooth, and level surface.
2. Place a spacer board on the ground underneath the auger shave plate between the skid shoes. The thickness of the board should be the same as the height above the ground you wish to raise the auger shave plate. The skid shoes should not touch the board.

With the two nuts loose allow the skid shoe to slide to the ground then tighten the nuts to secure the skid shoe.

8. Once the engine has started. Slowly move the choke lever all the way to the "OPEN" position. Allow the engine to run for several minutes before attempting to clean snow.

CLEARING SNOW

Start the engine once your snow thrower has been running outside for several minutes, it is now ready for use. Make sure the path in front of your Snow Thrower is free from people, animals, objects, and all other obstructions except for snow.

Adjust the chute outlet to the desired direction.

Turn the chute rotation handle clockwise or counter-clockwise until the desired position is reached.

Never direct the chute outlet toward people or animals. While snow may seem harmless, it can contain rocks or other debris that can cause serious injury when projected through the chute.

1. Engage/depress the auger control lever (handle) to start the augers and impeller turning.
2. Set the desired direction and speed using the speed/gear control lever.
3. Engage/depress the drive control lever (handle) and direct the snow thrower into the snow to be cleared.

NOTICE: NEVER change speed/gear positions while the drive control lever (handle) is engaged. Disengage the drive control handle BEFORE changing speeds or directions. If the snow is deeper than the height of the auger, remove it in several steps taking narrower swaths. Make several passes with the auger overlapping the cleared areas and reduce forward speed.

For the best clearing efficiency, clear snow before it melts, refreezes and hardens. Hard packed and wet snow can be very difficult to clear.

Clearing wet heavy snow can be a challenge, depending on ambient temperature, humidity levels, and overall climate conditions including actual snow conditions, there may be no 100% solution as snow may be too wet or compacted to move or throw. Wet snow will tend to clog and stick more to the augers and chute. Keep the auger engaged as much as possible when clearing wet snow to help prevent clogging.

If snow is filled with foreign material, damage to the snow thrower may result. Avoid snow with foreign materials.

STOPPING

When finished using your snow thrower, perform the following steps to shut it down.

1. Engage the auger and impeller for 30 seconds to clear any remaining snow inside your snow thrower
2. Stop the auger blade rotation by releasing the (left) auger control lever (handle).
3. Remove Engine Safety Switch Key to stop engine operation.
4. Remove snow from all snow thrower surfaces including the auger housing and chute areas.

CLEARING RESTRICTIONS

If the snow discharge chute or auger housing becomes clogged, STOP the engine. Remove the Engine Safety key and make sure that all rotating parts have come to a complete stop. Use the supplied snow clean out tool to clear the obstruction. After unclogging, wipe the tool clean, and place it in the holder on top of the auger housing.

MAINTENANCE

TIRE INFLATION

Before each use of your Snow Thrower, check the tire pressure. The pressure in each tire should be in the range of 20-24 psi for the best performance. The pressure can be checked using an ordinary tire pressure gauge. Fill the tires using a small or pressure regulated air compressor.

DO NOT OVER-INFLATE THE TIRES. Over-inflating could cause a tire to burst and cause severe bodily injury.

SHAVE PLATE REPLACEMENT

Remove both skid shoes and hardware including carriage bolts and nuts which attach shave plate to snow thrower housing. Reassemble new shave plate, making sure heads of the carriage bolts are to the inside of the auger housing.

AUGER OR IMPELLER JAMS

The auger and impeller rotate at fast speeds which can cause harm or even amputation to a person's body parts. Even if you do not see the auger or impeller rotating, it may start at any time if the engine is running. Remove the Safety Key before cleaning the jams. The chute clean-out tool is fastened to the upper tube.

1. Always turn OFF the engine before attempting to clear any clogs or jams.
2. Keep hands and feet away from rotating parts while the engine is running.
3. Do not wear loose fitting clothing that can become entangled in rotating parts.
4. Wait until the auger and impeller have come to a full stop.
5. Clear any visible jams using the clean out tool attached to your machine.

DO NOT try to clear jams with your hands or feet.

AUGER SHEAR PINS REPLACEMENT

Shear pins are used to attach the auger shaft to the auger blades. Stop the engine by removing the safety key. A clog or jam in the augers may cause one or multiple shear pins to break. The shear pins are a safety mechanism and designed to break under high load or impact and protect the auger drive system from damage. Replacement shear pins and nylon locknuts are provided with your snow thrower.

For additional replacement shear pins, please call the customer service department at (800)791 9458.

1. Turn off the engine and wait for all moving parts to come to a complete stop. Remove any remnants of the broken shear pin. It may be necessary to unscrew the nut from the broken shear pin and drive out the broken pin.
2. Insert a new shear pin through the hole in the auger shaft and tighten using the shear pin nylon lock nut. Do not over-tighten the nylon lock nut.
   Note: Never replace the shear pins with standard pins or fasteners. Damage may occur to the snow blower and drive systems.

NOTICE: Never replace the shear pins with standard pins or fasteners. Damage may occur to the snow blower and drive systems.

TROUBLESHOOTING

Before attempting to make any inspections, repairs or adjustments, stop the engine, wait for all moving parts to stop moving and carefully disconnect the engine spark plug wire. If tipping or turning the snow blower is required for any inspection or repair, first wait until the engine is cool to the touch and then drain the engine of all fuel and oil into suitable containers and store or dispose of in a proper manner.
