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 specified 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 floor. 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.



Clearing a Jam

• In the event of a jam, ensure that all personnel are clear of both the input chute and the cutting head.

• Hold the SHREDDER REVERSE button for 5-7 seconds. This will cause the cutters to run backwards for as long as the reverse button remains pressed.

• Release the reverse button. The machine will come to a stop. After the machine has completely stopped, press the forward button and try to shred material.

• If machine jams again, reverse shredder, LOCK OUT POWER, and manually remove the jammed material.

• Restart machine in the forward direction to resume operation.

Warning: NEVER hold the forward button as damage to the machine and the elec-trical system may occur.

Shut-Down Procedure

• Allow input chute and output conveyor to clear all material before shutting down. Wait approximately 30 seconds.

• 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 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 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 the either 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 for effective tracking.

Air Filtration System

The air filtration 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, filter cleaning, and filter changes. The frequency of the inspections is dependent on usage.

HEPA Filter

Pre-Filter



Warning: Always de-energize the unit using proper LOTO procedures before cleaning, lubricating, maintaining, removing any guards, and after shredding operation is complete.

Note: See maintenance schedule for inspection, cleaning, and replacement frequencies.

Steps for checking Air Filtration System:

1. De-energize the unit using proper Lock Out Tag Out (LOTO) procedures.

2. Tools Required: 1/2” wrench or socket wrench

3. Inspect the air inlet of the AFS by removing the two bolts in the conveyor access panel on top of the conveyor on the rear of the unit and pulling up the cover to look inside. Inlet will be on the left from the rear of the machine.

4. Replace the prefilter. This can be accessed from the front of the shredder by removing the maintenance access panel below the control station. With panel removed, the prefilter will be exposed, and the prefilter can be removed. Note: Handle the prefilter with care. Do not jar or drop the prefilter as it is covered with dust from shredded media/drives.

5. Be sure to thoroughly clean the inside of the prefilter compartment, pulling out any strips or tape.

IMPORTANT: Prefilter must be installed so that the arrow is pointing towards the fan. The arrow on the frame of the prefilter points in the direction of the air flow. The air flow for the AFS goes from left to right.

Conveyor Access Bolts



6. The final inspection point is at the back of the shredder at the HEPA filter. Simply inspect the HEPA filter by visual observation. The side of the HEPA filter you can see should be an even white color across the entire surface. The HEPA filter will also have an airflow indicator arrow. Install the filter so that the arrow is pointing outwards from the machine.

a.) Clean the HEPA filter by placing in an empty bag with the airflow arrow facing up.

b.) Lift the filter approx. 1’ (0.3 m) from the ground and drop it several times.

c.) Vacuum both sides of the filter.

.

Note: If the HEPA filter does not appear to be white, then your prefilter could potentially be damaged and should be replaced. If there is an area on the surface of the HEPA filter that appears dark or dirtier than the rest of the filter, then your HEPA filter is potentially damaged and should be replaced.

Cutting Head Adjustment

Be sure to de-energize the unit using proper LOTO procedures before adjusting the cutting head. SEM recommends using certified service personnel to adjust the cutting head if necessary.

• Over tightening of cutting head can result in excessive wear to wear plates and cutters. This may also shorten cutter and bearing life.

• Cutting head adjustments MUST be made on a COLD cutting head that has not been run within at least twelve hours.

• Ensure that the cutting head has been thoroughly cleaned and that the cutters move freely on the shafts.

Cutter clearance should be checked if any of the following conditions exist:

• Shred capacity drops noticeably.

• Media is passing through cutters without being completely shredded.

• Cutting head becomes extremely hot.

• Abnormal noise being generated from cutting head.

• Noticeable large gap between two cutters.

To Check/Set Cutter Clearance:

• Tools Required:

• 1/2” – 9/16” Wrench

• 3/16 Allen Wrench

• Lock out machine power to prevent injury.

• Remove rear guard.

• Clean and oil the cutting head ensuring that there are no obstructions.

• Locate the set screws on the chain side of the cutting head.

• Loosen the jam nut and using an Allen wrench to turn the screws clockwise to close the gap.

• Once the wear plate touches the cutter, back the screw off half a turn. Tighten the jam nuts and replace all guards and covers.
