Model 0305 & 0304 Operation and Maintenance Manual Turn machine on and run machine in forward for five minutes. Stop machine and turn power off. Draw a mark on each adjustment nut with asharpie to track changes made in next step. Make all adjustments in small increments. By design, the conveyor belt should have1/16” or less clearance between it and the side frames. Remove shroud if neededto check the alignment position. Adjust alignment by tightening adjustment nut one quarter turn at a time on theside of conveyor where the belt is rubbing the side frame. Tightening will move thebelt away from the nut being tightened. Fully tighten jam nuts up to plate. Replace bearing covers. Turn power on and run machine in forward for five minutes.If additional alignment is required, repeat the above steps.Note: When the machine is run in reverse the belt may run slightly off center to theeither side. This is normal. The belt will stretch during the first few days of operation.This will affect alignment since the belt alignment relies in part on proper tensioning foreffective tracking.Air Filtration SystemThe air filtration system (AFS) on this device is designed to help reduce possible odorsand possible contaminants from escaping into the atmosphere during the process ofhard drive destruction. The AFS is a low maintenance system that only requires periodicinspection, filter cleaning, and filter changes. The frequency of the inspections isdependent on usage.HEPA FilterPre-Filter18SEM www.semshred.com
