WARNING
DO NOT attempt any adjustments, maintenance, service, or repairs with engine running. Stop auger. Stop engine. Remove key. Remove spark plug wire and secure wire away from spark plug.
4.1AUGER BELT ADJUSTMENT/REPLACEMENT When operating machine release the auger clutch control. The auger should come to a complete stop in 5 seconds. If auger 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 BELT 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 1/2” to 3/4” when the clutch control is depressed. See Figure 4.1.
