To adjust the auger belt tension
Note: An assistant is necessary to do this task.
1. Remove the belt cover. See
replacement of the belts on page 21 .
2. Loosen the idler pulley nut (A).(Fig. 82 )
3. Move the idler pulley (B) in the direction of the auger
belt to increase the belt tension. Move it away from
the auger belt to decrease the belt tension.
4. Tighten the idler pulley nut (A).
5. Have the assistant stay 3 m (10 feet) in front of the
product to monitor the movement of the auger.
6. Push and then release the auger engagement to
start and stop the auger.
7. Measure the time for the auger to stop moving. If the
auger stops after more than 5 seconds, release the
belt tension.
8. When the auger stops moving after less than 5
seconds, install the belt cover. See
cover on page 21 .
To adjust the auger control cable
1. Remove the cable cover on the right hand side of the
frame (D).(Fig. 83 )
2. To remove slack from the auger control cable,
unscrew the bottom jam nut (B) and tighten the top
jam nut (B) until the auger belt tension has
increased.
3. Retest the auger engagement. Repeat adjustment
as needed until only a small amount of slack remains
in the cable when the lever is disengaged.
4. Tighten the bottom jam nut to lock in the tension.
Note: You may also tension the auger belt by
adjusting the idler pulley as a secondary option. If
the adjustment does not resolve the problem,
replace the auger belt. See
on page 22 .
