Sterling 2000, 1200, SMS 850, 1500 manual Setting the Cutting Knives

WARNING! Danger of cutting caused by sharp cutters at all times—even when rotor is at standstill. Serious Injury especially to the hands and fingers can occur. Wear protective gloves!

Setting the Cutting Knives

Cutters for the SMS series shredder do not have to be adjusted. All adjustments have to be done with the bed cutters. To simplify cutter setting and shorten standstill periods when replacing cutters, bed cutters have 4 adjusting screws, 2 each for pushing and pulling the cutter. Having several cutter sets helps to avoid standstill periods. Correct and careful setting of the gap between the cutters and bed knives (cutting gap) is important for productive capacity of the shredder. Factors for the size of the cutter gap are the size of the rotor, the design of the rotor, and the material to be ground.
