ASSEMBLY

Your Snow Thrower will require some assembly. Please complete the following steps before using your Snow Thrower. For easy assembly, we recommend attaching the components in the order listed in this manual.

Chute Assembly

1. Install the discharge chute onto the chute

flange on the housing. The chute only rests on the flange.

WARNING! Never use your hands to clear a clogged chute assembly. Shut off engine and remain behind handles until all moving parts have stopped before unclogging.

J. Chute Assembly

The chute provides a discharge path for snow being thrown. The chute is adjustable.

2. Attach the chute rotation bar to the mount bracket onto the chute housing using two hex screws, washers and locknuts. Tighten fasteners securely.

NOTICE: Make sure all fasteners are tightened before starting the machine.

Handle Assembly

1. Attach the lower handles using four (4) bolts. Each side will require two (2) bolts.

3. Slide the upper chute crank rod through the mounting hole under the control panel and into the lower chute crank rod.

4. Align the holes and connect the crank rods using the Phillips head screw and hex nut.

2. Attached the upper handle to the lower handle using four (4) knobs, washers and bolts.

NOTICE: Do not bend or kink the control cables. The cables should be routed under the handle assembly and not wrapped around the handle or knobs. The cables must move freely and not bind.

3. Secure the speed control cables to the handle with provided clips.

Note: Do not secure the auger or drive control cables with the clips.

Wheel Installation

1. Raise and support the rear of the snow thrower to allow the installation of the wheels.

Skid Shoe Installation and Adjustment

1. Locate the pair of skid shoes from parts bag and remove the bolts.

2. Loosely install the skid shoes using the bolts, washers and hex nuts as shown on each side of the auger housing.

2. Slide the wheels onto the axle (one on each side) and align the hole on the wheel hub with the hole in the axle.

3. Install a retaining pin through each wheel to secure. Insert the pin then pivot the ring over the axel hub.

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 just scrapes 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.

3. Move the Snow Thrower to a solid, smooth, and level surface.

4. 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.

5. With the two (2) nuts loose allow the skid shoe to slide to the ground then tighten the nuts to secure the skid shoe.

Pre-Operation Inspection IMPORTANT!!!

Review the SAFETY section in this manual and the ENGINE manual before operating the engine and snow thrower.

WARNING! 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, 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.

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 in the ENGINE manual?

• Has the engine been filled with oil 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 auger, drive and speed controls cables routed properly so that are not kinked and controls operate smoothly?

• Are the auger, drive and speed controls cables adjusted correctly?

• 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 customer service department.

Auger and Drive Controls

1. To engage the auger, press down on the auger control handle (left side handle).

2. To engage the drive, press down on the drive control handle (right side handle). The machine should start moving in the direction and speed that the speed control lever is set to.

Drive Speed Control Lever

Move the drive speed control lever to the desired speed. There are six (6) settings: four (4) forward speeds and two (2) reverse speeds. 1 is the slowest forward speed and 4 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.

3. When finished clearing a snow path, release the auger control handle and the drive control handle.

Note: Release (disengage) the auger and drive control handles before adjusting the drive speed control lever. Never change the drive speed while your snow thrower is moving, it could damage the drive mechanism and void the warranty.

Chute Discharge Direction Adjustment

WARNING - 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 left; counterclockwise to move the chute to the right.

Chute Discharge Angle Adjustment

WARNING! Always disengage the drive and auger control handles before making adjustments. Make sure the augers are stopped and the machine is not moving.

The angle of the chute deflector controls the discharge distance of the snow. Raising the angle will increase the distance. Lowering the angle will decrease the distance.

Adjust the chute outlet to the desired direction. Turn the chute rotation handle clockwise or counter-clockwise until the desired position is reached.

WARNING! 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 handle to start the augers and impeller turning.

2. Set the desired direction and speed using the speed control lever.

3. Engage/depress the drive control handle and direct the snow thrower into the snow to be cleared.

NOTICE: Do not change speed positions while the drive is engaged. Disengage the drive control handle BEFORE changing speeds or directions.

1. Loosen the knobs on the chute deflector and adjust the chute deflector to the desired angle.

2. Retighten the knobs. Do not over-tighten.

WARNING! An opening between the discharge chute and the chute deflector may allow foreign objects to be picked up by your Snow Thrower and be thrown in the direction of the operator causing severe bodily injury. Do not advance the chute deflector too far forward causing an opening to appear between the deflector and discharge chute. Do not over tighten the knobs on the chute deflector.

OPERATING YOUR SNOW THROWER

Starting

Please refer to ENGINE manual (separate document) for engine operation instructions.

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.

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

Clearing Snow

Start the engine (see ENGINE manual) 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.

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 by releasing the left control handle.

3. Set the engine switch to the OFF position. See ENGINE manual for stopping procedures.

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, and make sure that all rotating parts have come to a complete stop. Remove the spark plug cap from the spark plug.

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

WARNING! Never perform maintenance while your Snow Thrower is running. Turn OFF the engine before performing any maintenance tasks on your Snow Thrower.

Proper maintenance of your Snow Thrower will help prolong its life. Please perform the following maintenance procedures as required.

Maintenance Procedures

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 an small or pressure regulated air compressor.

WARNING! 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 housing.

Check the bolts at frequent intervals for proper tightness to ensure that the equipment is in safe working condition.

After each snow removal session, run the Snow Thrower for a few minutes to prevent the collector/impeller from freezing. Stop the engine, wait for all revolving parts to stop completely, and wipe residual ice and snow off the unit. Rotate the chute rotation handle several times to remove any excess snow.

Auger or Impeller Jams

WARNING! 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.

The chute clean-out tool is fastened to the top of the auger housing with a mounting clip and a cable tie at the factory. Cut the cable tie before operating the snow thrower.

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.

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

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 hex nut. Do not over-tighten the hex nut.

Auger Shear Pin Replacement

Shear pins are used to attach the auger shaft to the auger blades. 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 to 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.

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

Drive Control Cable Tension Adjustment

WARNING! Entanglement Hazard - Before performing any adjustment procedures, make sure the engine is off and remove the spark plug wire from the spark plug to ensure the engine cannot accidently start. Never adjust cable tension with the engine running.

The drive control cable is located on the right side (when standing behind the snow blower) and is made up of an upper and lower cable connected by an adjustment plate. The adjustment plate is located in-line with the cable below the control handle and is covered by a black plastic slip cover. The adjustment plate is used to adjust the drive control cable drive wheel friction tension.

1. Stop the engine.

2. Disconnect the upper cable from the drive control handle.

3. Slide up the slip cover to access the adjustment plate.

Note: The upper cable end must be in the upper single center hole of the adjustment plate. Do not change the position of the upper cable.

5. Connect the upper cable to the control handle.

6. Start the engine and engage the drive control handle to test the operation of the drive engagement.

Note: With the drive control handle at the full released position, the cable should be barely tight. Some slack in the cable may be required to ensure the drive control is not engaging the drive friction wheel. There should be no drive movement with the drive control handle released. If the drive is engaged when the drive control handle is released, loosen the cable tension by readjusting the cable as necessary. Do not over tension the cable.

Drive Speed Control Cable Adjustment

WARNING! Entanglement Hazard - Use caution when performing the speed control cable adjustment.

1 – Upper Drive Control Cable (Always in upper center

hole) 2 – Adjustment Plate 3 – Lower Drive Control Cable 4 – Slip Cover 5 – Adjustment Plate Lower Cable Opening

4. Adjustment is made by changing the position of the lower cable in the adjustment plate holes (1 to 9). Only move the lower cable diagonally one hole at a time from its original position.

The speed control lever is connected to two cables that work in tandem to control machine speed and direction. As the speed control lever is moved from forward to reverse gears (right to left) one cable is pulled and one is pushed.

Depending on if the cable setting is biased towards forward or reverse, adjustment of the cables will vary.

To adjust the cables one cable should be moved up and the other down equally in their respective brackets until there is a positive direction change when the lever is shifted between F1 and R1. The middle position between these two settings is neutral (there is no actual neutral "notched" position on the control panel)

1. With the engine running engage the drive control handle and move the speed control lever between F1 and R1 to determine which way the cables need to be adjusted. Release the drive control handle when shifting between gears.

2. Loosen the jam nuts on each cable (only one or two threads) and move each cable up and down as required until a positive direction change is achieved when the lever is shifted between F1 and R1. This may take multiple attempts to find the exact setting.

Over time, the auger cable tension may loosen and or the auger belt may stretch. The auger cable will require periodic adjustment to compensate for these changes. Ideally, the cable should just be barely tight when the auger handle is in the released (disengaged) position.

Note: The proper operating tension for a typical Vbelt drive is - the lowest tension at which the belt will not slip under a loaded condition.

3. Tighten the cable jam nuts once the proper setting has been achieved.

Auger Belt Tension Adjustment

Note: During operation the augers turn at a slower speed than the impeller, this is normal. The augers are used to chop and cut the snow and direct it into the impeller which is rotating at a high speed to throw the snow up and out of the chute.

(1 to 9). Only move the lower cable diagonally one hole at a time from its original position.

Note: The upper cable end must be in the upper single center hole of the adjustment plate. Do not change the position of the upper cable.

5. Connect the upper cable to the control handle.

6. Start the engine and engage the auger to test the operation of the auger.

Note: With the auger control handle at the full released position, the cable should be barely tight. Some slack in the cable may be required to ensure the auger pulley tension pulley is not engaging the belt. There should be no auger movement with the auger handle released. If the auger is turning when the auger handle is released, loosen the belt tension by readjusting the cable as necessary. Do not over tension the cable.

A loose belt will cause:

• Premature belt wear / damage /cracking /fraying

• Belt slipping ("squealing may also be heard")

• No or erratic/slow auger operation - poor performance

A tight belt will cause:

• Premature belt wear / damage / breaking/stretching

• Belt overheat / burning

• Loss of auger engagement control (always engaged)

• Tension pulley damage

• Pulley bearing damage

Auger Belt and Related Component Inspection

When replacing your snow blower auger belt it is important to determine the cause of the failure (if applicable) and take corrective action to avoid repeated failure.

1 – Drive Pulley 2 – Tension Pulley 3 – Auger Pulley

• Foreign material on pulleys, oil, grease, dirt, etc.

• Misaligned tension pulley

• Tension pulley loose or damaged

• Tension pulley and arm assembly operation

• Does the tension arm move freely both engage and disengage directions without binding?

• Misaligned tension pulley, the pulley should move parallel to the belt centered to the belt

• Check return spring operation and tension

Inspect the auger engagement handle and cable:

• Cable and connection damage

• Free movement (from engage to disengaged positions)

• Binding or improperly routed cable

• Cable pulley(s) damage, misalignment and binding

• Cable adjustment plate damaged or improper installation

• Handle damaged or binding at pivot

Inspect the belt:

• Correct size and type

• Fraying or peeling apart

Storage

WARNING! Never store your Snow Thrower for extended periods of time with fuel in the tank. Fuel stabilizer can be added to the fuel to extend its shelf life for storage.

Store the unit, in a locked, dry place out of the reach of children to prevent unauthorized use or damage. Cover loosely with a tarp for added protection.

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.

Note: 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.
