Once clearance is established, fully tighten the adjustment cam screws. 6. Repeat steps 1 through 5 for all bed combs. 7. Fully tighten all bed comb adjustment screws to 12 ft/lbs. 5-5 Adjusting the Sensitivity of the Optional Bin LevelMonitor !!! DANGER !!! Because electrical power must be supplied to the sensor to permit testing andadjustment, it is EXTREMELY VITAL that you secure the machine for normaloperations. Do so by closing the cutting chamber and hopper access door, which returns thesafety limit switch to the closed position, PRIOR to beginning any sensoradjustments to ensure the safety of personnel. Although the bin level sensor was installed and tested at the factory to ensure reliable operation, variations in the physical properties of the material run through the granulator require that you adjust the sensor to suit your particular requirements. Follow these steps during initial pre-operational electrical testing and whenever you change the type of material run through the granulator. Page 30 Step 1: Fill the bin with granulate of the material you intend to run through the granulator. Make sure the bin is filled to a level that covers the front face of the latex sensor covering located on the rear wall of the bin. Step 2: Make sure that power is supplied to the machine by turning the main disconnect switch to the ON position and connecting the control enclosure to the main power source. DO NOT START THE MACHINE. Step 3: Locate the sensor on the rear wall of the machine base. Using a small screwdriver, locate and turn the potentiometer located on the rear face of the sensor. • Turning the potentiometer clockwise (CW) increases sensitivity and activates the alarm. • Turning counterclockwise (CCW) decreases sensitivity and shuts off the alarm. With the bin in place, turn the potentiometer so that the alarm sounds, then rotate counterclockwise (CCW) until the alarm just goes off. Now rotate clockwise (CW) one-half to one ( . to 1) turn. The sensor is now set and the unit is ready to granulate new material 5-6 Recommended Spare Parts List A Recommended Spare Parts List is part of the operation and installation package that arrives with your new machine.

Shut machine down and check. Vacuum line may be clogged. Clean as needed. Stringy granulate Comb gap is too large. Adjust to proper gap specification. Combs are dull. Reverse bed comb or replace combs and re-install. Fines Combs are dull. Reverse bed comb or replace combs and re-install. Excessive power required; blown fuses Overloading of the machine. Reduce amount/size of feedstock put into the machine. Combs are dull. Reverse bed comb or replace combs and re-install. Comb gap is too large. Adjust to proper gap specification. Machine stalls Overloading of machine. Reduce amount/size of feedstock put into the machine. Pieces of feedstock jammed in the rotor. Clear the jammed material then visually inspect the rotor to insure it is not damaged and that the comb gaps are correct. Bearings sound noisy or are hot Lack of lubrication. Lubricate per maintenance instructions. Overloading of the machine. Reduce amount/size of feedstock put into the machine. Bearings have exceeded their rated life.
