chute every 45−60 seconds, depending on size of the items being destroyed and the screen size. For
screens smaller than 1/8”, and larger media such as enterprise devices, feed rates may double.
a. Warning: Do not insert rotational media into this unit. Doing so will damage the unit and void
your warranty.
b. Caution: Feeding drives too quickly may cause a jam or damage the screen.
2.) When the collection bin is full, the BIN FULL light and the STOP pushbutton will illuminate. The stage 1
chamber will stop, and the stage 2 chamber will initiate a timed shutdown.
a. After timed shutdown has completed, open the collection bin door and empty the contents of
the collection bin.
b. Re-insert the bin before starting the unit again.
c. When the BIN FULL light is illuminated the collection bin will weigh approximately 25 lbs.
i. Disclaimer: If destroying lighter material in volume the BIN FULL light may not
illuminate when the bin is filled. SEM recommends that the operator gauge how much
material is run to avoid overflow and potential damage to the unit.
3.) If STAGE 1 experiences a jam, the unit will automatically reverse up to five times to clear the jam. If the
jam is not “automatically’ cleared, the unit will go into a timed shutdown mode illuminating both the
11
508.366.1488 | www.semshred.com
RESET pushbutton and the STOP pushbutton.
4.) To restart the unit, press the RESET pushbutton. When the unit is ready to run, the RESET button will
extinguish.
5.) Next, press the START pushbutton to restart the unit. If the unit is still jammed, the media may have to
be removed manually.
