Anleitung Zusammenfassung
If the auger/impeller does not come to a complete stop in the required time, check and adjust belt tension. Inspect belts frequently for signs of excessive wear. Observe drive belts for slippage due to wear when operating machine. If slippage does occur, adjust/replace as follows. 4.1.1. AUGER and WHEEL DRIVE CABLE ADJUSTMENT 1. Measure control cable extension from a relaxed position to full extended position. Move control lever against handle. Measure the overall length of the spring. The length of the cable spring should increase by 3/8” when the clutch control lever is depressed. See Figure 4.1. CABLE MUST BE SLACK WHEN CLUTCH HANDLE IS RELEASED CABLE CONNECTOR JAM NUT CABLE SPRING SPRING SHOULD STRETCH 3/8” WHEN LEVER IS DEPRESSED FIGURE 4.1 2. Adjust control cable by loosening jam nut at the upper end of cable. Hold threaded end of cable and then turn cable clockwise or counter clockwise until correct extension is achieved. Retighten jam nut. IMPORTANT: DO NOT over tighten the control cables. The cables must have slack for the auger/impeller brake to function properly and for the wheel drive to de-clutch properly. If the auger control cannot be properly adjusted, belt adjustment and/or replacement will be required. Refer to Section “Auger Belt Idler Pulley Adjustment”. If the wheel drive control cannot be properly adjusted, the rubber drive tire will require replacement. 4.1.2. AUGER BELT IDLER PULLEY ADJUSTMENT NOTE: To adjust the idler pulley and properly tension the auger belt, the auger control cable adjustment must first be loosened as described in the following step. Cable adjustment must be checked after completing the idler pulley adjustment. 1. Loosen jam nut at the end of cable. Hold threaded end of cable and then turn metal housing of cable counter clockwise until threaded portion of cable is extracted from metal housing. Reinstall 1/2” of the threaded portion of cable back into metal housing. Retighten jam nut. 2. Remove belt cover. See Figure 4.2 REMOVE BELT COVER FIGURE 4.2 3. Loosen nut and bolt that secures the idler pulley. Move idler toward belt for more tension or away from belt for less tension. See Figure 4.3. Retighten bolt and nut securely.

Stop auger. Stop engine. Remove key. Disconnect spark plug wire and secure wire away from spark plug. Before tilting machine, drain all the fuel from fuel tank. Allow engine to run, outdoors where fumes can be safely dissipated, until all fuel is removed from carburetor. 4.1.2. AUGER DRIVE BELT ADJUSTMENT (IDLER PULLEY ADJUSTMENT) (Continued From Previous Page) 4. Recheck cable for proper extension (3/8”). 5. Reinstall belt cover. 4.1.3. AUGER DRIVE BELT REPLACEMENT Inspect belt frequently for signs of excessive wear. Visually check engine drive belt for cracking, fraying, severed or exposed belt strands. 1. Remove belt cover. See Figure 4.2. 2. Remove discharge chute. 3. Unhook both idler springs. 4. Loosen auger/impeller belt guide. See Figure 4.4. IMPORTANT: Wheel drive belt will have to be removed from around engine drive pulley and engine shaft to install auger drive belt. 5. Remove auger drive belt from around engine pulley. See Figure 4.4. WHEEL DRIVE BELT BELT GUIDE AUGER DRIVE BELT UNHOOK IDLER SPRING UNHOOK IDLER SPRING 6. Tilt machine forward to gain access to drive system area. Secure machine in the tilted position to prevent tipping over. Remove drive system cover plate. See Figure 4.5. SELF-TAPPING SCREWS REMOVE COVER FIGURE 4.5 7. Remove auger drive belt from drive disc pulley. Route auger belt through drive system in between rubber drive tire and drive disc. 8. Route new auger drive belt through drive system. NOTE: New belt has to be routed in between rubber drive tire and drive disc to position it around auger pulley. 9. Reinstall wheel drive belt onto engine wheel drive pulley. Make sure belt is also positioned in the drive disc pulley groove. 10. Route auger drive belt around engine auger drive pulley. Make sure belt is also positioned in the drive disc pulley groove. 11. Position belt guide against auger drive belt and tighten securely. 12. Reinstall both idler springs. 13. Reinstall discharge chute, belt cover and drive system cover. Tighten screws securely. 14. Adjust idler for proper belt tension and control cable for proper spring extension. Refer to Section “Auger Belt Idler Pulley Adjustment”. FIGURE 4.4 14 Section 4 - REPAIR & ADJUSTMENTS WARNING DO NOT attempt any adjustments, maintenance, service, or repairs, with engine running. Stop auger. Stop engine. Remove key. Disconnect spark plug wire and secure wire away from spark plug. Before tilting machine, drain all the fuel from fuel tank. Allo...
