A forklift is ideal for the purpose, but take care to properly po sition the fork s between the casters and t he centrally mounted evacuation pi pe from the side of the mach ine.
Page 24 of 53 4 Install ation 4-1 Lif ting Importan t! Before lifting or moving the granula tor, check the relative w eight shown on the shipping pape rs and in Figure 7. To facilitate the lifting o peration using forklift trucks, t he drop box has been removed from the granulator and is packed with an y spare parts.

Page 26 of 53 1. Open the back cover, and i nsert the power cable from underneath the granulator. 2. Pass the power cable thro ugh the appropriate hole, and i nsert it into the control panel thr ough a connector placed at t he base.
Page 27 of 53 4. Pivot back the feed hopper to gain fr ee access to the cutting chamber. 5. Check that there are no f oreign objects in the cutting chamber. 6. Check to be sure the bed knife and rotor knife bolts are at the proper torque and the knife gap is set according to specifications.
Page 28 of 53 If the rotation direction is correct, t he granulator is read y to use. If the rotation direction is incorrect, rev erse the rotor direction as follows: !!Warning !! A LICENSED ELECTRICI AN must carry out this operation. 1. Disconnect and lockout the power to th e machine at the incoming power source.
Page 29 of 53 Before undertaking an y ty pe o f work on the machin e, use a feeler gauge to check the distance betw een the bed knives and the rotor knives (the knife gap). To access the cutting chamber, follow t he same procedure and observe the precautionary steps given in Section 4-4-1.
Page 30 of 53 5 Start Up and Operat ion 5-1 Pre-Opera tional C hecklist To ensure the granulator is ready for operation, perform the tasks listed on the following pre-operati onal checklist. Make sure that all electrical and mechani cal machine elements are inspected and any defects corrected first .
Page 31 of 53 5-2 Operatio n The granulator can be op erated in a vertical top feed pos ition or in a horizontal front feed posit ion. Before starting the granul ator, always check for and remove tools or any other objects placed on t he granulator.
Page 32 of 53 6 Maintenance 6-1 General Re comme ndations Before carrying out an y work on the granulator, carefull y read the instructions contained in thi s manual.
Page 33 of 53 6-2 Monthl y Maintenance Opera tions 6-2-1 Drive Bel t Tension NOTE: Thi s operation should be carried out by an operator / mechanical maintenance engin eer. For the granulator to function correctly, it is extremely important that the drive belt is always tight.

Page 35 of 53 4. Remove the screw knob that hol ds the hopper on top of th e cutting chamber. Carefull y lower the screen cradle assembl y, resting it on the base.
Page 36 of 53 4. Using a feeler gauge, me asure the gap between th e rotor and knife cutting edges. Check each rotor kni fe to find the “high knife” or the knife that m easures the smallest gap. If the gap is substantiall y greater than the specified 0.

Page 38 of 53 8. Install new or sharpened bed kni ves on each knife seat, making sure that the rotor is blocked to prevent it from rotating while installing each knife.
Page 39 of 53 5. Loosen and remove the k nife bolts and lift the knife off the knife seat removing it from t he cutting chamber. 6. Perform the above steps until all the rotor knives are removed. NOTE: Before replacin g the rotor knife with new or sharpened knives, wipe the knife seats on th e rotor, being sure to clean off all process material.
