CARING FOR YOUR SHREDDER
Clean covers with a clean dry cloth. Do not use water or solvents. Make sure
you disconnect your shredder from its power source before cleaning.
Paper shredders, like all mechanical equipment, need proper maintenance to
ensure efficient operation. Periodic lubrication of the cutting blades is
important to offset the friction generated within the cutting head. Frequency of
lubrication will vary depending on the shred size and the amount of usage. A
strip-cut shredder 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 lubricating your shredder is simple, and can be performed
by any operator. The oil is packaged in a squeeze bottle and is applied
directly to the cutting blades through the feed opening (3). Run a fine stream
of lubricant from one side of the feed opening 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.
DAHLE Shredder Oil is the only lubricant you should use in your paper
shredder. It has been specially formulated so as not to leave any residue that
could attract dust and clog the shredding mechanism. You can order DAHLE
Shredder Oil (item # 740) from your local dealer.
Repairs on your paper shredder should only be performed by qualified
technicians. If you need service, contact your local dealer, or you can
contact DAHLE USA Customer Service between 8:30 am and 5:00 pm EST at
(800) 995-1379.

SHREDDING
Turn shredder on. Press Forward Button (4) to begin shredding operation.
The shredder can be fed either from the top or the front. For this purpose, a
feed opening is provided on the top for emptying waste paper baskets (paper
only) and at the front for feeding cut stock and continuous forms.
Three (3) EDP shelves can be folded up to facilitate the shredding of
continuous forms.
The shredder will not operate unless the Waste Door (9) and Access Door (13)
are completely closed.
Microfiche and transparencies can also be shredded in the same manner as
paper, however, you should shred a piece of paper after every 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
one 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.
