SETTINGS AND ADJUSTMENTS

SECTION 4-1

Adjusting or Replacing Bed Knives

BASIC FACTS ABOUT THE KNIVES

All of the rotor knives are ground in sets to equal dimensions. Mount and service them as sets. The rotor knives must be mounted tightly against the backs of the knife seats, in order to make it

possible to achieve consistent knife clearances.

Rotors with adjustable rotor knives require setting of the knife length prior to installation on to the

rotor. Knife length setting is accomplished by using the fixture supplied with the machine, see Section 4-35.

Accurate cutting clearance is obtained by setting the bed knives to a 0.006 in. to 0.008 in. (0.15

mm to 0.20 mm) gap from the rotor knives.

The bed knives are adjusted by turning captive adjusting screws. For best results, start with the bed

knives adjusted to a wide gap from the rotor knife, and slowly adjust them to the required gap by turning the screws in the same direction; avoid reversals. Reversals introduce inaccuracies due to backlash.

CHECK ALL SETTINGS AND ADJUSTMENTS BEFORE GRANULATING ANY MATERIAL

Proper adjustments and settings are made prior to shipment, however the machine may require readjustment. The standard knife gap setting is between six and eight thousandths of an inch (0.006 in. to 0.008 in. or 0.15 mm to 0.20 mm).

NOTE: These instructions apply to both the upstroke (the bed knife furthest from you when you service the cutting chamber) and the down-stroke bed knives.

A malfunction of the machine, such as a jam, may cause undue strain or damage to any part. Do not restart the machine after such a malfunction without checking to see whether damage was done or whether settings were changed by the malfunction.

TURN OFF AND LOCKOUT the power per OSHA 1910.147 OR ANSI Z244.1-1982 (Lockout/Tag-out of Energy Sources).

If it is not possible to lock out the power, have an electrician remove the fuses. Make sure the rotor has come to a complete stop.
