4.1 AUGER BELT ADJUSTMENT/REPLACEMENT
When operating machine release the auger clutch
control. The auger should come to a complete stop in
5 seconds. If the 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.

cable must have slack for the auger brake to function
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”.
