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. 3-6. 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.
4 Controls and Features Figure 4-1 Snow thrower controls and features are described below and illustrated in Fig. 4-1. Choke Control NOTE: For detailed information on all engine controls, refer to the separate Tecumseh Engine Operator’s Manual. Shift Lever The shift lever is located in the right side of the handle panel and is used to determine ground speed and direction of travel. Forward There are six forward (F) speeds. Position one (1) is the slowest and position six (6) is the fastest.
Throttle Control Auger Control The throttle control is located on the rear of the engine. It regulates the speed of the engine and 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.
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. 6. Recoil Starter 1. Make certain both the auger control and drive control are in the disengaged (released) position. Move throttle control up to FAST position. Insert ignition key into slot. Make sure it snaps into place. Do not attempt to turn the key. 2.
To Engage Drive 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. To Engage Augers 1. To engage the augers and start throwing snow, squeeze the auger control against the left handle.
6 Maintenance & Adjustments Maintenance Lubrication Engine Gear Shaft Refer to the Tecumseh 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.
Auger Shaft Adjustments At least once a season, remove the shear pins from the auger shaft. Spray lubricant inside the shaft and around the spacers and the flange bearings found at either end of the shaft. See Fig. 6-3. Shift Cable If the full range of speeds (forward and reverse) cannot be achieved, refer to the figures to the right and adjust the shift cable as follows: 1. Place the shift lever in the fastest forward speed position. 2. Loosen the hex nut on the shift cable index bracket. See Fig.
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.
7 Service Belt Replacement 3. Auger Belt Carefully pivot the snow thrower up and forward so that it rests on the auger housing. 4. Remove the frame cover from the underside of the snow thrower by removing four self-tapping screws which secure it. See Fig 7-3. To remove and replace your snow thrower’s auger belt, proceed as follows: 1. To prevent spillage, place a piece of plastic wrap under the gas cap and tighten securely. 2.
6. Remove the belt from around the auger pulley, and slip the belt between the support bracket and the auger pulley. See Fig. 7-5. Drive Belt To remove and replace your snow thrower’s drive belt, proceed as follows: 1. Place a piece of plastic under the gas cap. 2. Remove the plastic belt cover on the front of the engine by removing the two self-tapping screws. Refer to Fig. 7-1. 3. Remove the belt as follows. See Fig. 7-6.: a.
