Checking the Knife Gap | Sterling BP1012, BP1018 guide

Before undertaking any type of work on the machine, use a feeler gauge to check the distance between the bed knives and the rotor knives (the knife gap).

To access the cutting chamber, follow the same procedure and observe the precautionary steps given in Section 4-4-1. Before proceeding to the checks, it is advisable to block the rotor to avoid any inadvertent rotation.

Once you have safely accessed the cutting chamber, check the current distance between the bed knives and the rotor knives using a feeler gauge. (See Figure 12.)

NOTE: The distance set by the manufacturer for normal application is 0.006”-0.008” (0.15-0.20 mm). If the gap between the bed knives and the rotor knives is found to be greater than that, an adjustment must be made. (See Section 6-4: Inspection and Adjustment of Knives.)

Once you have checked the knife gap, close the hopper, secure it with the appropriate swing bolts, reinsert the bin, and close the front panel.
