4.Using a feeler gauge, measure the gap between the rotor and knife cutting edges. Check each rotor knife to find the “high knife” or the knife that measures the smallest gap. If the gap is substantially greater than the specified 0.006” - 0.008” (0.15 mm – 0.2 mm), the knives need readjustment.
5.Loosen the bed knife locking bolts. (See Figure 16.)
6.Leave the two outside bolts just tight enough to allow the bed knife to move.
7.Loosen the adjustment screws and lock nuts. (See Figure 16.)
8.Insert a 0.006” – 0.008” (0.15 mm – 0.2 mm) thickness gauge between the cutting edge of the bed knife and that of the high rotor knife.
9.Adjust the bed knife into the rotor knife using the adjustment screws, so as to leave enough space for the thickness gauge to move.
NOTE: Check that the distance between the fixed and rotating knife is the same at both ends of each knife. Move the bed knife using the push adjusting screws a little at a time on each end.
10.When adjustment is complete, tighten the lock nuts on the adjustment screws.
11.Torque the bed knife bolts to 95 lbs./ft. (13 Kgm., 128 Nm) using a torque wrench.
12.Repeat the steps
13.Close the hopper and replace the screen and screen cradle, securing them in place using the swing bolts provided.
14.Close the front and rear doors, and unlock the power or replace the fuses in the control panel. Turn the disconnect switch to “ON”.
