Adjusting or Replacing Rotor 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 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.

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.

The hydraulic cylinders or jackscrews, which open the machine, should not operate until the rotor is completely stopped. If you discover that the hydraulic cylinders or jackscrews DO operate while the rotor is still turning, immediately shut down the machine and call for maintenance to adjust it.

Wear gloves to protect against injury from the rotor or bed knives.

OPEN THE CUTTING CHAMBER INTERLOCK

Disengage the interlock actuator screw with a box wrench or a ratchet wrench.

Make sure the end of the interlock actuator screw is visible and clear of any contact.

When disengaged, the interlock opens the electrical control circuit to the motor and prevents the machine from running.
