Important Safe Operation Practices 2 WARNING! This symbol points out important safety instructions which, if not followed, could endanger the personal safety and/or property of yourself and others. Read and follow all instructions in this manual before attempting to operate this machine. Failure to comply with these instructions may result in personal injury. When you see this symbol.
Safe Handling of Gasoline 5. To avoid personal injury or property damage use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Serious personal injury can occur when gasoline is spilled on yourself or your clothes which can ignite. Wash your skin and change clothes immediately. Never run an engine indoors or in a poorly ventilated area. Engine exhaust contains carbon monoxide, an odorless and deadly gas. 6.
Clearing a Clogged Discharge Chute Hand contact with the rotating impeller inside the discharge chute is the most common cause of injury associated with snow throwers. Never use your hand to clean out the discharge chute. To clear the chute: 1. SHUT THE ENGINE OFF! 2. Wait 10 seconds to be sure the impeller blades have stopped rotating. 3. Always use a clean-out tool, not your hands. Maintenance & Storage 1. Never tamper with safety devices. Check their proper operation regularly.

3 Assembly & Set-Up Contents of Carton • One Snow Thrower • Two Replacement Auger Shear Pins • One Snow Thrower Operator’s Manual • One Briggs & Stratton Engine Operator’s Manual Assembly Handle 1. Place the shift lever in the Forward-6 position 2. Observe the lower rear area of the snow thrower to be sure both cables are aligned with roller guides before pivoting the handle upward. See Fig. 3-1.
3. Finish securing chute control assembly to chute support bracket with wing nut and hex screw removed earlier. See See Fig. 3-4. Set-Up Shear Pins A pair of replacement auger shear pins and bow tie cotter pins are included with your snow thrower. Store them in your snow thrower’s dash panel until needed. See Fig. 3-5. Figure 3-4 4. Check that all cables are properly routed through the cable guide on top of the engine. See Fig. 3-5.
Tire Pressure Adjustments Before operating, check tire pressure and reduce pressure in both tires to between 15 psi and 20 psi. Skid Shoes NOTE: If the tire pressure is not equal in both tires, the machine may not travel in a straight path and the shave plate may wear unevenly. The snow thrower skid shoes are adjusted upward at the factory for shipping purposes. Adjust them downward, if desired, prior to operating the snow thrower.
Auger Control Warning! Prior to operating your snow thrower, carefully read and follow all instructions below. Perform all adjustments to verify your snow thrower is operating safely and properly. Check the adjustment of the auger control as follows: 1. When the auger control is released and in the disengaged “up” position, the cable should have very little slack. It should NOT be tight. 2. In a well-ventilated area, start the snow thrower engine. Refer to Starting the Engine on page 12.

NOTE: For detailed information on all engine controls, refer to the separate Briggs & Stratton Engine Operator’s Manual.
Stop Switch Auger Control The stop switch is located on the rear of the engine. It will shut off the engine when moved into the STOP position. Primer Pressing the primer forces fuel directly into the engine’s carburetor to aid in cold-weather starting. Oil Fill Engine oil level can be checked and oil added through the oil fill. Skid Shoes Position the skid shoes based on surface conditions. Adjust upward for hard-packed snow. Adjust downward when operating on gravel or crushed rock surfaces.
Chute Directional Control Chute Clean-Out Tool 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. The chute clean-out tool is conveniently fastened to the rear of the auger housing with a mounting clip.
5 Operation Starting The Engine 1. 2. 3. Attach spark plug wire to spark plug. Make certain the metal loop on the end of the spark plug wire (inside the rubber boot) is fastened securely over the metal tip on the spark plug. 7. Recoil Starter 1. Make certain both the auger control and drive control are in the disengaged (released) position. Insert ignition key into slot. Make sure it snaps into place. Do not attempt to turn the key. 2.
To Engage Drive Replacing Shear Pins 1. With the throttle control in the Fast (rabbit) position, move shift lever into one of the six forward (F) positions or two reverse (R) positions. Select a speed appropriate for the snow conditions and a pace you’re comfortable with. 2. Squeeze the drive control against the handle the snow thrower will move. Release it and drive motion will stop. The augers are secured to the spiral shaft with two shear pins and cotter pins.
6 Maintenance & Adjustments Maintenance Lubrication Engine Gear Shaft Refer to the Briggs & Stratton Engine manual packed with your machine for all engine maintenance. The gear (hex) shaft should be lubricated at least once a season or after every twenty-five (25) hours of operation. Shave Plate and Skid Shoes 1. The shave plate and skid shoes on the bottom of the snow thrower are subject to wear. They should be checked periodically and replaced when necessary.
Adjustments Auger Shaft At least once a season, remove the shear pins from the auger shaft. Spray lubricant inside the shaft and around the spacers along the shaft. Using a grease gun, apply two strokes of grease (Part Number 737-0168A) to the fitting found at each end of shaft. See Fig. 6-3. Vent Plug Shift Cable If the full range of speeds (forward and reverse) cannot be achieved, adjust the shift cable as follows: 1. Place the shift lever in the fastest forward speed position. 2.
Drive Control Chute Directional Control When the drive control is released and in the disengaged “up” position, the cable should have very little slack. It should NOT be tight. If the chute assembly does not have full range from left-to-right, the chute control cables can be adjusted to take up slack: NOTE: If excessive slack is present in the drive cable or if the snow thrower’s drive is disengaging intermittently during operation, the cable may be in need of adjustment. 1.
