HOPPER ADJUSTMENTS (continued)
To adjust the cylinder...
1
Hold the hopper switch in the HOPPER UP position just long enough for the hopper to tilt forward.
2
Reach behind the top of the hopper, loosen the lock nut on the hopper cylinder rod and turn the rod
clockwise to increase downward flex of channel “B” or counter clockwise to decrease downward flex of
channel “B”.
3
Close the hopper and check your adjustment. Repeat adjustment if necessary. If adjustment is good, tilt
hopper again and tighten the lock nut on the cylinder rod.
Hopper Dump Door Adjustment
The gasket on the dump door must seal air tight against the front of the hopper for proper machine operation.
Before adjusting the dump door cylinders, check the condition of the gasket and replace it if damaged. To
adjust the hopper door cylinders, loosen the lock nuts on the cylinder rods and turn the cylinder rods.
