14. Procedure to Open/Close the Disintegrator
PROCEDURE TO OPEN THE DISINTEGRATOR
• Allow all material to run out of the cutting chamber.
• Shut OFF and LOCKOUT all power including the main disconnect switch.
• Open the machine by loosening the hex coupling nut(s) at the front of the machine enough to allow for rotation of
threaded swing bolts out of the clamp(s).
• NOTE: It is never necessary to loosen the spring-block locknuts located on the front of the cutting chamber. The spring
blocks are factory set and require no adjustment.
• Apply a lifting pressure to the hopper in order to swing the machine up and back to the fully open position.
• For machines equipped with hydraulic jacks: Utilizing the jack handle, ensure the jack needle valve is fully closed by
turning it clockwise until fully seated. Insert the jack handle into the pump pivot and pump the jack piston until the
cutting chamber is fully up and back to the extreme open position (refer to the instruction label on the machine base).
• NOTE: In the fully open position, the machine is designed to remain open without the use of any devices; however, a
safety latch has been provided to prevent accidental closing of the machine. The safety latch is located on the right
side of the cutting chamber and should always be checked to verify that it has fallen into position upon opening the
machine.
• CAUTION: The knives mounted on the rotor and also located at the edges of the cutting chamber are extremely sharp.
Always wear heavy gloves and use extreme care when working in the cutting chamber.
PROCEDURE TO CLOSE THE DISINTEGRATOR
• Ensure that all tools, rags, screws, etc. are removed from the inside of the cutting chamber and screen chamber.
• If previously removed, place the screen back into its original position, ensuring it is fully seated within the cradle.
• The machine is designed to remain open by using the counter balance springs and safety latch. To close the chamber,
apply hand pressure to the hopper to allow the safety latch to release, by way of the pull-cable mechanism. The
cutting chamber can now be easily lowered to close the machine.
• For machines equipped with hydraulic jacks: The safety latch pull cord, located on the right side of the machine,
should be pulled to disengage the safety latch. Utilizing the jack handle, slowly turn the jack needle valve 1/8-1/4 turn
counter clockwise to slowly lower the cutting chamber.
• The closing speed of the cutting chamber can be regulated by turning the needle valve clockwise or counter clockwise
as needed (refer to the instruction label on the machine base).
• Securely close the machine by rotating the threaded swing bolts up into the clamps and tightening the hex coupling
nut(s) at the front of the machine.
• Recheck all components to ensure that they are properly fastened.
