time.
Chute Blocker: If this unit is equipped with a chute blocker, be sure that it is covering
the correct chute. To change chutes, lift the knob and slide it towards the chute that is
not in use.
Reminder: DO NOT SHRED ROTATIONAL HARD DRIVES USING THE SSD CHUTE.
New Operators: New operators should be given a minimum 2-3 hour equipment
training time, beginning with a slow feed rate, approximately one drive every 10-15
seconds. The operator will soon be able to judge how quickly the shredder can be fed.
Debris Drawer Lock (Optional): The debris drawer is equipped with a lock and blue
key if CE or specied at purchase. Turn the key before opening the drawer. Do not
attempt to force the drawer open or open drawer while unit is running.
Important/Warning: The debris drawer is attached to keep excess material from col-
lecting on oor. Drawer must be emptied frequently (approx. every 100 drives) or dam-
age to the belt and unit may occur. Debris drawer should be emptied at the beginning
and end of each operator’s shift regardless of the number of drives shredded.

• Turn machine on and run machine in forward for ve minutes.
• Stop machine and turn power off. Draw a mark on each adjustment nut with a
sharpie to track changes made in next step.
• Make all adjustments in small increments. By design, the conveyor belt should have
1/16” or less clearance between it and the side frames. Remove shroud if needed
to check the alignment position.
• Adjust alignment by tightening adjustment nut one quarter turn at a time on the
side of conveyor where the belt is rubbing the side frame. Tightening will move the
belt 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 ve 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 the
either side. This is normal. The belt will stretch during the rst few days of operation.
This will affect alignment since the belt alignment relies in part on proper tensioning for
effective tracking.
Air Filtration System
The air ltration system (AFS) on this device is designed to help reduce possible odors
and possible contaminants from escaping into the atmosphere during the process of
hard drive destruction. The AFS is a low maintenance system that only requires periodic
inspection, lter cleaning, and lter changes. The frequency of the inspections is
dependent on usage.
