14 14 15 16 15 16 17 18 Auger Shave Plate Shear Pin 17 18 19 19 Skid Shoe Auger Housing Tire Drive Control Handle The Drive Control Handle is used to engage and disengage the drive wheels. Pull up on the Drive Control Handle to engage the wheels; release to disengage. Speed Control Lever The Speed Control Lever is located in the right side and is used to set the drive speed and direction of travel. It can be moved into any of six positions.
Position the shoes based on the surface conditions. Adjust upward for hard-packed snow. Adjust downward when operating on gravel or crushed rock surfaces. Auger When engaged, the augers rotate to cut snow and direct it into the impeller housing to be discharged out the chute. Clean-out Tool The chute Clean-out Tool is conveniently fastened to the rear of the auger housing with a mounting clip. It is used to clean the chute assembly and chute opening when snow and ice become lodged.
ASSEMBLY AND ADJUSTMENTS The following section describes steps necessary to prepare the snow thrower for use. If after reading this section, you are unsure about how to perform any of the steps please call (800) 791-9458 Mon-Fri 9-5 EST for customer service. Failure to perform these steps properly can damage the snow thrower or shorten its life. Unpacking Unpack the snow thrower and all its parts, and compare against the list below. 1. Snow Thrower 2. Discharge Chute Assembly 3.
Step 2 – Attach Auger and Drive Cables 1. Push drive control handle inward to detach from the upper handle. 2. Attach drive cable to the hole on drive control handle bar. 3. Re-attach drive control handle to the upper handle. 4. Repeat step 1-3 to attach the auger cable. 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.
Step 3 – Chute assembly 1. Loosen and remove the three sets of screws, locknuts and washers on the discharge chute. 2. Hold the discharge chute and handle to align the mounting holes to chute base mount holes. Insert the screws and washers and secure with locknuts. Do not over-tighten the screws. Note: Make sure all fasteners are tightened. Step 4 – Skid shoes installation and adjustments 1. Locate the pair of skid shoes from parts bag and remove the bolts. 2.
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.
AUGER AND DRIVE CONTROLS 1. To engage the auger, push back the auger control handle; release to disengage. 2. To engage the drive, pull up on the drive control 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.
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. 1. Loosen the knobs on both side of the chute deflector and adjust the chute deflector to the desired angle. 2. Retighten the knobs. Do not over-tighten.
OPERATING YOUR SNOW THROWER STARTING Please refer to ENGINE manual (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.
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.
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. AUGER SHEAR PINS REPLACEMENT Shear pins are used to attach the auger shaft to the auger blades.
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. 3. Tighten the cable jam nuts once the proper setting has been achieved.
AUGER BELT INSTALLATION WARNING! Entanglement Hazard – Before performing any service procedures, make sure the engine is off and remove the spark plug wire from the spark plug to ensure the engine cannot accidently start. 1. Push the auger tension pulley arm to move the auger brake to allow access for installation of the belt into the auger pulley. 2.
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. Inspect the belt: • Correct size and type • Missing pieces • Burning • General damage • Fraying or peeling apart • Cracks and tears • Uneven wear patterns • Foreign material on belt, oil, grease, dirt etc.
TROUBLESHOOTING Problem Causes Remedy WARNING - 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.
Problem Drive system No forward or reverse drive movement when drive handle engaged Causes Remedy Drive belt loose or damaged Check drive belt tension pulley for damage or incorrect tension, repair as necessary. Replace drive belt.
Problem Auger System Auger belt broken, or repeated failure Auger rotating when auger control handle released Causes Remedy Auger tension pulley arm return spring broken or missing Replace tension arm return spring Auger tension pulley arm stuck or binding Repair or replace tension arm as necessary Auger tension pulley arm or pulley misaligned or damaged Repair, replace or align tension arm and or pulley as necessary Foreign material on pulleys and belt, oil, grease, dirt etc.
