Release to stop the augers. Replacing Shear Pins The augers are secured to the spiral shaft with two shear pins and cotter pins. If the auger should strike a foreign object or ice jam, the snow thrower is designed so that the pins may shear. If the augers will not turn, check to see if the pins have sheared. See Fig. 5-3. CAUTION: NEVER replace the auger shear pins with anything other than OEM Part No. 738-04124A replacement shear pins. Any damage to the auger gearbox or other components as a result of failing to do so will NOT be covered by your snow thrower’s warranty. WARNING! Always turn off the snow thrower’s engine and remove the key prior to replacing shear pins. Figure 5-3 sectiOn 5 — OperatiOn Maintenance & Adjustments Maintenance Engine Refer to the Engine Maintenance section. Shave Plate and Skid Shoes 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. To remove skid shoes: 1. Remove the four carriage bolts and hex flange nuts which secure them to the snow thrower. 2. Reassemble new skid shoes with the four carriage bolts (two on each side) and hex flange nuts. Refer to Fig. 6-1. To remove shave plate: r Figure 6-1 3. Remove the carriage bolts and hex nuts which attach it to the snow thrower housing. 4. Reassemble new shave plate, making sure heads of carriage bolts are to the inside of housing. Tighten securely. Tire Pressure Before operating, check tire pressure and reduce pressure to between 15 psi and 20 psi. If the tire pressure is not equal in both tires, the unit may pull to one side or the other. Lubrication Gear Shaft The gear (hex) shaft should be lubricated at least once a season or after every twenty-five (25) hours of operation. 1. Allow the engine to run until it is out of fuel. 2. Carefully pivot the snow thrower up and forward so that it rests on the auger housing. 3. Remove the frame cover from the underside of the snow thrower by removing four self-tapping screws which secure it. Refer to Fig 7-3. 4. Apply a light coating of engine oil (or 3-in-1 oil) to the hex shaft. See Fig. 6-2. NOTE: When lubricating the hex shaft, be careful not to get any oil on the aluminum drive plate or the rubber friction wheel. Doing so will hinder the snow thrower’s drive system. Wipe off any excess or spilled oil. Figure 6-2 Wheels At least once a season, remove both wheels. Clean and coat the axles with a multipurpose automotive grease before reinstalling wheels. Auger Shaft Adjustments At least once a season, remove the shear pins from the auger Shift Cable shaft. Spray lubricant inside the shaft and around the spacers and the flange bearings found at either end of the shaft. If the full range of speeds (forward and reverse) cannot be See Fig. 6-3. achieved, refer to the figures to the right and adjust the shift Figure 6-3 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. 6-4. Figure 6-4 3. Pivot the bracket downward to take up slack in the cable. 4. Retighten the hex nut. Auger Control Refer to the Assembly and Set-up section for instructions on adjusting the auger control cable. Chute Assembly Refer to the Assembly and Set-up section for instructions on adjusting the skid shoes chute assembly. Skid Shoes Refer to the Assembly and Set-up section for instructions on adjusting the skid shoes. sectiOn 6 — Maintenance & adjustMents Drive 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. 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. Check the adjustment of the drive control as follows: 1. With the drive control released, push the snow thrower gently forward. The unit should roll freely. 2. Engage the drive control and gently attempt to push the snow thrower forward. The wheels should not turn. The unit should not roll freely. 3. With the drive control released, move the shift lever back and forth between the R2 position and the F6 position several times. There should be no resistance in the shift lever. 4. If any of the above tests failed, the drive cable is in need of adjustment. Proceed as follows: Figure 6-5 5. Loosen the lower hex nut on the drive cable bracket. See Fig. 6-5. 6. Position the bracket upward to provide more slack (or downward to increase cable tension). 7. Retighten the upper hex nut. Chute Directional Control If the chute assembly does not have full range from left-to-right, the chute control cables can be adjusted to take up slack: 1. Using a .” wrench, loosen the upper and lower hex nuts found on one cable adjuster. 2. Grasp the metal cable housing and gently pull downward to take up slack (usually no more than 1.4-inch) in the cable before retightening both hex nuts...
