4.1  AUGER/IMPELLER and WHEEL DRIVE BELT 
ADJUSTMENT/REPLACEMENT 
When operating machine release the auger/impeller 
clutch control. The auger/impeller should come to a 
complete stop in 5 seconds. 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. 
 
 
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. 
Refer to Section “Rubber Drive Tire 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 
 
 
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.
