SHREDDING
Turn shredder on. Insert paper squarely into
Feed Opening (3). A light barrier will automatically activate the shredding mechanism.
Continue feeding paper into the Feed Opening
until the shredding mechanism begins to
draw the paper in. At this point, allow the paper
to feed into the shredder on its own. Once the
paper has passed completely through the shredding mechanism, the electronic
controls will automatically stop the machine.
To shred a piece of paper too small to break the light barrier, press the
FORWARD button (7) once to o verride the auto ON/OFF f unction. The shredder
will continue to run until the FORWARD button is pressed again.
Microfiche and transparencies can also be shredded in the same manner as
paper, however, you should s hred a piece of paper after ever y 8 or 10 sheets of
plastic. This helps clean plastic particles out of the shredding mechanism.
CAPACITY
Capacity is the number of sheets of 8½” x 11” paper that can be shredded at on e
time. These figures are approximate and machines may vary slightly due to
various conditions. It is not recommended that you try to run your shredder at
maximum capacity, as this increases the chance of a paper jam.

CLEARING A PAPER JAM
If too many sheets of paper are f ed into your shredder at one t im e, it m ay cause a
paper jam. Running your s hredder at maximum c apacity increases the chanc e of
a paper jam. If a paper jam occurs, it is easy to clear by following thes e simple
steps:
The Auto-Reverse feature, built into the electronic versions of DAHLE High
Capacity Shredders, helps prevent paper jams. If the Auto-Reverse feature is
activated an audible alarm sounds and the Paper Jam Indicator (6) lights up. If
this situation occurs, follow these simple steps:
1. Remove paper from Feed Openi ng. The REV ERSE button ( 7a) m ay be used
if excess paper rem ains in the Feed Opening. Clear shredding mechanism
by pressing the FORWARD button (7).
2. Separate some of the sheets and continue shredding.
CHANGING THE SHRED BAG
When the Shred Bag is full, the shredder will automatically shut down. On the
electronic models an LED indicator will light and an audible alarm will sound.
Changing the Shred Bag is quick and easy if you follow these simple directions.
1. Turn shredder off
2. Open Door (11) using Door Handle (10) to ex pose Waste Bin (9) an d Shred
Bag.
3. Slide Waste Bin and full Shred Bag from shredder.

CARING FOR YOUR SHREDDER
Clean covers with a clean dr y cloth. Do not use water or solvents. Mak e sure you
disconnect your shredder from its power source before cleaning.
Paper shredders, like all mechanical equipment, need proper maintenance to
ensure efficient oper ation. Peri odic lu brication of the c utting bla des is im portant t o
offset the friction ge nerated within the cutting hea d. Frequency of lubrication will
vary depending on the s hred size and the amount of usage. A strip-cut shr edder
receiving light use (1 – 2 hours per week) will require lubrication only once or
twice a month, while the same machine used 1 – 2 hours per day will require
lubrication weekly. A cross-cut shredder should be lubricated every ½ hour of
shredding time to maintain maximum capacity and efficiency.
The procedure for lubricati ng your shredder is simple, and can be perform ed by
any operator. The oil is pack aged in a sque eze bot tle and is appl ied direc tl y to the
cutting blades through the f eed opening (3). Run a fine stream of lubricant fr om
one side of the feed ope ning to the other. Run the shredder in REVERSE for a
few seconds to help distribute the lubricant evenly. You can now continue
shredding as usual.
