• 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.
• 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.
• • • • • • • • • • • • • • Check bolts and screws for proper tightness (EVERYTIME 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.

Squeeze the Drive Control Handle against the upper handle to engage the wheels; release to disengage. Drive Speed/Gear Control The Speed/Gear Control is located on the center of the panel and is used to set the drive speed and direction of travel.
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 assistance. Failure to perform these steps properly can damage the snow thrower. Unpacking Unpack the snow thrower and all its parts, and compare against the list below. 1. Snow Thrower 2. Discharge Chute Assembly 3. Upper handle 4.
***Assembling Drive, Auger & Shift Cables over the top of the Frame Handle will cause unnecessary tension in the cables, resulting in the Snow blower propelling forward when starting the engine and may cause damage to the drive & auger control (levers) when trying to engage them. 4. Cut and remove all tie wraps that are on Cables, Frame Handles, Drive Control (Lever) & Auger Control (Lever). 5. Verify that the connection for the Upper & Lower Drive/Auger Cables is accurate.
Figure 4 2. Attach Chute Handle to base of Chute Gear Connection and secure with Cotter Pin, as indicated on Figure 5. Figure 5 Step 4 – Skid shoes installation and adjustments 1. Locate the set of skid shoes from 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.
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 16 fl. oz. For general use, we recommend 5W, 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).
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 immediately, remove the obstruction, and inspect it for damage. Repair or replace any damaged parts before restarting and operating you snow thrower.
L Auger Control Lever (Handle) Drive Control Lever (Handle) R 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 six (6) settings: four (4) forward speeds and two (2) reverse speeds.
OPERATING YOUR SNOW THROWER MANUAL START THE ENGINE To manual start the engine, perform the following steps: 1. Check the oil and fuel levels. 2. Turn the fuel valve to the “ON” position. 3. Move the choke lever to the “CLOSE” position. 4. Make sure insert the switch key. 5. Press the primer bulb 3 times. 6. Pull on the recoil starter handle slowly until a slight resistance is felt, then pull quickly to start the engine. Return cord gently into the recoil starter. Never allow the cord to snap back. 7.
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.
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 a 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.
2. Insert a new shear pin through the hole in the auger shaft and tighten using the shear pin nylon locknut. Do not over-tighten the nylon locknut. NOTICE: Never replace the shear pins with standard pins or fasteners. Damage may occur to the snow blower and drive systems. DRIVE SPEED CONTROL CABLE ADJUSTMENT WARNING! Entanglement Hazard – Use caution when performing the speed control cable adjustment.
Screw Step 1 Step 2 Step3 4. Left Side - Loosen the hex nuts attaching the auger housing to the main frame. 5. Right Side - Remove the hex nuts, lock washers and flat washers attaching the auger housing to the main frame. 6. Remove the belt from the drive pulley while pulling the right side of the auger housing away from the main frame just enough to access the belt and auger pulley. 7. Push the auger tension pulley arm to move the auger brake, away from the belt to allow removal of the belt. 8.
Note: The belt guide pin helps keep the belt in the pulley when the belt is disengaged. The pin should not be tight to the belt. The pin should be loose enough to allow the belt to spin freely but not allow the belt to jump off the pulley. 5. Connect the upper cable to the auger control handle. 6. Install belt cover using (Qty. 2) hex screws. WARNING! Ensure the belt cover is installed and all safety guards are in place before the engine is started and at all times when the engine or machine are operating.
STORAGE & CLEANING PROPER STORAGE PROCEDURES WARNING! Never store your snow shrower for extended periods of time with fuel in the tank or carburetor. Fuel stabilizer can be added to the fuel in can 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.
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.
