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.

Check Oil Level

1. Remove the dipstick (A, Figure 3) and wipe with a clean cloth.
2. Install and tighten the dipstick (A, Figure 3).
3. Remove the dipstick and check the oil level. Correct oil level is at the top of the full indicator (B, Figure 3) on the dipstick.

Add Oil

1. If the oil level is low, slowly add oil into the engine oil fill (C, Figure 3). Do not overfill. After adding oil, wait one minute and then check the oil level.
2. Reinstall and tighten the dipstick (A, Figure 3).

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 0.8gallons.
   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 (872)314 0005.

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 CONTROL
Move the drive speed control lever to the desired speed. There are forward and reverse speeds.

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.

OPERATING YOUR SNOW THROWER

MANUAL START THE ENGINE
To manual start the engine, perform the following steps:

1. Check the engine oil. See theCheck Oil Level section.
2. Make sure equipment drive controls, if equipped, are disengaged.
3. Move the throttle control (A, Figure 5), if equipped, to the fast position. Operate the engine in the fast position.
4. Move the fuel shut-off (B, Figure 5), if equipped, to the open position.
5. Insert the key (C, Figure 5), and turn to the on position.
6. Move the choke control (E, Figure 5) to the choke position.
   Note: Choke is usually unnecessary when restarting a warm engine.
7. Push the primer (F, Figure 5) two times.
   Note: Priming is usually unnecessary when restarting a warm engine.
8. Rewind Start, if equipped: Firmly hold the starter cord handle. Pull the starter cord handle slowly until resistance is felt, then pull rapidly.

ELECTRIC START THE ENGINE
Connect the extension cord to the power cord receptacle 120V and then into a wall receptacle. Depress the push button. After you start the engine, disconnect the extension cord from the wall receptacle and then from the power cord receptacle.
As the engine warms up, move the choke control (E, Figure 5) to the run position.

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. 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 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. Key, if equipped: Turn the key (C, Figure 5) to the off position. Remove the key and keep in a safe place out of the reach of children.
4. After the engine stops, move the fuel shut-off (B, Figure 5), if equipped, to the closed position.
5. 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.

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 lock nuts are provided with your snow thrower.
For additional replacement shear pins, please call the customer service department at (872)314 0005.

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.
