3. As shown in the image, pinch the belt with medium force. The gap
between the belts must be a ½” gap (+ - 3/16”).
Note, that if a belt is brand new, it may be tighter. To verify correct
tension with a new belt, replace belt cover, and run the 4090 chipper
at full RPM for 10 mins. Then recheck belt tension. The 10-minute
run will break in the belt and will show a more accurate tension.
4. If the belt is not tensioned correctly, loosen the 4 engine mount
bolts. Then slide the engine back and forth as needed.
Note, only a small movement on the engine changes the belt tension
quickly. Move the engine at 1/8” increments for best results.
5. Retighten engine, double check the belt for the correct tension.
6.
Once the belt gap is showing in the correct 1/2” gap spec, the belt
guard can be reinstalled, and the chipper is ready for operation.
