INSTALLATION
SECTION 3-3
Removal of Protective Coating
The pneumatic cylinder, which opens the machine, should not operate until the rotor is
completely stopped. If you discover that the pneumatic cylinder DOES operate while the rotor is
still turning, immediately shut down the machine and call for maintenance to adjust it.
Wear gloves to protect against injury from the rotor or bed knives.
REMOVE THE PROTECTIVE COATING
The machine is shipped with a protective wax coating, which must be removed prior to start-up.
The coating can be removed with an acceptable solvent, such as mineral spirits.
Clean the following areas:
Inside the feed hopper
Inside the cutting chamber (knives, rotor, etc.)
Inside the discharge area.
Be sure that the screens are properly installed into the cutting chamber and that nothing has
fallen into the cutting chamber during transportation and/or installation. Refer to Section 6,
Maintenance, for the procedure entitled Screen Replacement and Cutting Chamber Access.
Check to be sure the bed knife and rotor knife hold-down screws are tight and knife clearances
are correct. Refer to Section 4, Settings and Adjustments.
Before operating the granulator, it is extremely important that a licensed electrician correctly
wires the machine into the plant power source. See Section 8, for wiring diagram.
All electrical equipment must be properly grounded in accordance with local and national codes
to protect personnel from electrical shock.
A fusible, lockable disconnect between the plant power source and the machine electrical
cabinet is highly recommended.
