Unpacking

Unpack the snow thrower and all its parts, and compare them against the list below.

1. Snow Thrower
2. Discharge Chute Assembly
3. Lower Handle
4. Chute Rotation Handle
5. One Pair of Skid Shoes with hardware
6. 4 Extra Shear Pins and Locknuts

ASSEMBLY

• Your Snow Thrower will require some assembly. Please complete the following steps before using your Snow Thrower.

Step 1 – Handle assembly

1. Attach the lower handle using four (4) bolts. Each side will require two (2) bolts.
2. Attach the upper handle to the lower handle using (4) knobs, washers and bolts.

Step 2 – Chute assembly

1. Remove the bolt and nut from the chute base.
2. Slide the chute into the chute base.
   • Note: The chute slides into the base, if the chute fits tightly use a light lubricant to assist installation. In some cases, the chute lip may have excess material from manufacturing, it is acceptable to carefully remove some material from the chute lip in order to allow the chute to slide into the chute base.
3. Securely install the supplied bolt and nut

Step 3 – Chute rotation handle assembly and installation

1. Insert the chute rotation handle eyebolt into the hole located halfway up the left handle. Secure with 2 cupped washers and hex nut.
2. Connect the chute rotation handles (upper and lower) using the screws provided.

Step 4 – Skid shoe installation and adjustments

1. Locate the pair of skid shoes from the parts bag and remove the bolts.
2. Loosely install the skid shoes using the bolts and hex nuts as shown on each side of the auger housing. Make sure the skid shoe tip faces out. 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.
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.

SNOW THROWER PREPARATION

PLEASE REFER TO ENGINE MANUAL (SEPARATE DOCUMENT) FOR ENGINE OPERATION INSTRUCTIONS.

• The following section describes steps to prepare your Snow Thrower for use. If after reading this section, you are unsure about how to perform any of the steps please call 1-800-791-9458 for customer service. Failure to perform these steps properly can damage your Snow Thrower or shorten its life. Review the SAFETY section in this manual and the ENGINE manual before operating the engine and 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.
• WARNING! 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 your Snow Thrower and inspect it for frozen parts. Thaw all parts before restarting and operating your Snow Thrower. Never force parts or controls that have frozen. Never use an open flame of any sort to thaw frozen parts.

Pre-Operation Inspection – IMPORTANT

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

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.

OPERATING YOUR SNOW THROWER

STARTING

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

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

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. 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.

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 the ENGINE manual for stopping procedures.
4. Remove snow from all Snow Thrower surfaces including the auger housing and chute areas

MAINTENANCE

• Proper maintenance of your Snow Thrower will help prolong its life. Please perform the following maintenance procedures as required. Please read the ENGINE manual for engine maintenance procedures.
• Do not attempt to repair your Snow Thrower unless you have the proper tools and instructions for disassembly and repair. 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
