clearance may need to be set to approximately 1/2 the
anticipated thickness of the material to be processed.
NOTE: The above clearance is slightly greater at the center of the
knives. This is a normal condition when the rotor knives are
mounted on a slant rotor.
6. Turn the rotor backwards while checking the clearances to
avoid cutting the feeler gauge.
7. Using the bed knife shield adjusting push screws, adjust the
shield until the bed knife exposure is 0.040” (1.0 mm). If strip
material is to be cut, reduce the knife exposure to less than the
strip thickness to prevent material build-up on the bed knives.
8. With the clearance set, tighten the bedknife/shield screws
evenly and torque the 16 mm screws to 200 Lbs./Ft (271 Nm).
NOTE: All screw tightening torque figures are for unlubricated
thread conditions. Screw threads should be wiped with an oil-
dampened block before installation to prevent galling.
9. Recheck the clearances and re-adjust if necessary.
10. Reset the downstroke cover in position and tighten in place
with the downstroke cover screws, which were removed in
Step 2. Make sure the safety switch actuator arm screw sets the
arm in the correct switch operating position.
11. Replace the line fuses, unlock the power supply, and turn the
Main Power switch to On.
6-2-2 Rotor Knife Clearance:
During use, the clearance between the rotor knives and the bed
knives will increase due to wear. This is a normal condition that
requires re-setting this clearance once or twice before it is
necessary to remove the knives for regrinding.
When new knives are fitted to the machine, adjustment of the bed
knives after approximately eight hours of running time may be
required. (The rotor knives cannot be adjusted; they are fixed in
position.)
Check for wear and clearance of the rotor knives completing the
following procedure:
1. Turn the Main Power switch to Off, lock out the power supply,
and remove the line fuses.
