3-6 Initial Start-up
This machine has been run under power and tested at the factory prior to shipment. The
necessary settings and adjustments have been made so that a minimum amount of setting up

1. Access the cutting chamber as described in Section 3-4 on page 16.
2. Thoroughly clean the rust preventative materials or grease from the inside of the
cutting chamber and screen.

4. Use a feeler gauge to check the clearance between the rotor and bed knives by
turning the rotor backwards. Rotating the rotor backwards gives a better feel and does
