3.1 Pre-Operation Checklist 

After all electrical and mechanical machine elements have been inspected and any defects corrected, the 
following pre-operational checklist should be used to ensure the disintegrator is ready for operation: 

•

 

Have all installation and preparation instructions been read and followed? 

•

 

Have the disintegrator operator and all other necessary personnel been fully trained on 
machine operation and all machine safety mechanisms? 

•

 

Have sufficient location clearances been allowed? 

•

 

Has the equipment been grounded as required by local codes and/or Article 250 of the National Electric 
Code? 

•

 

Have all motors been checked for rotation? 

•

 

Have all machine controls, buttons, and limit switch safeties been checked for proper functioning? 

•

 

Have the cutting and screen chambers been checked for foreign matter? 

•

 

Have the drive belts been checked for alignment and tension? 

•

 

Is the machine properly closed with all visible fasteners tight? 

•

 

Are all accessory components electrically and mechanically connected with proper support and with all 
fasteners tight? 

•

 

Are the cyclonic air separator and filter bags empty? (optional equipment) 

•

 

Has the fan/cyclone been verified for proper rotation direction? 

•

 

Are all electrical enclosure boxes tightly closed and clamped shut? 

•

 

Are all personnel clear of the machine? 

•

 

Does the machine have the correct size security screen for the desired particle outcome? 

•

 

Have the dust filter tubes been shaken? (Do this with the fan motor off.)
