Section 4 - REPAIR & ADJUSTMENTS
WARNING
Before attempting any adjustments, maintenance, service, or repairs, stop engine and auger/impeller, always remove key from ignition switch, remove spark plug wire and secure wire away from spark plug.
4.1AUGER/IMPELLER and WHEEL DRIVE BELT ADJUSTMENT/REPLACEMENT
When operating machine release the auger/impeller clutch control, auger/impeller should come to a complete stop in 5 seconds. If auger/impeller does not come to a complete stop in the required time, check and adjust belt tension. Inspect belt frequently for signs of excessive wear. Observe drive belt for slippage due to wear when operating machine. If slippage does occur, adjust as follows.
4.1.1.AUGER and DRIVE BELT ADJUSTMENT (CABLE ADJUSTMENT)
1.Measure control cable extension from a relaxed position to full extended position. Move control lever against handle. Measure from the top of spring (The top is in relation to where spring connects into connector). The cable spring should stretch 3/8” when the auger clutch control lever is depressed. See 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 rotate cable beyond the point to where all of the slack is out of cable. Cables have to have a certain amount of slack: When control lever is in the released position the cable slack allows: 1) Auger brake to stop auger/impeller. 2) Wheel drive to disengage. If all of the adjustment is utilized at the cable connector go to Section 4.1.2. for alternate adjustment.
4.1.2.AUGER BELT ADJUSTMENT (IDLER PULLEY ADJUSTMENT)
NOTE: Wheel drive belt idler pulley is not adjustable. If upper cable adjustment performed in Section 4.1.1. and correct cable extension can not be accomplished, adjustment can be made at the idler pulley. All adjustment made in Section 4.1.1. will have to be reversed from the upper end of cable.
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.

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.
