It is possible to put too much paper in nominal
shredder and automatic shredder simultaneously.
After the paper is wrinkled, there is a virtual position in the touching position of the AUTO bar. The paper cannot touch the AUTO bar,and
the micro switch cannot be closed. Put the paper back in, make sure the paper does not wrinkle when shredding, and the paper can fully touch the AUTO
lever.
Restart the machine to see
whether the machine returns to
normal.

Rated nominal paper used continuously for more than 5 minutes or automatic continuous shredding sheet for more than 20 minutes. If the machine is used continuously for
a long time, automatic protection will be turned on after the motor temperature control overheats. It is recommended that the machine rest for about 90 minutes before
use.
Use rated nominal paper for 3 minutes or
shred single paper for 10 minutes
It is recommended to rest the machine for 90 minutes and confirm
whether the machine can work properly after the machine has cooled
completely.
The shredding power is high. It is recommended that each shredding should comply with the nominal amount of shredding paper on the cover or
lower than the nominal amount of shredding paper, clean the scraps stuck to the cutter regularly, and use a special oil bag.
The machine is not in use, the
overheating light is on.
Overheating of the machine leads to circuit failure or

Problem solved
Whether the medium contains express bags, envelopes, advertising color pages
and other accumulated thickness of more than 6 75g/m2 or paper containing
adhesive.
The paper is too thick or the paper with adhesive paper on the surface makes the machine difficult to run, which leads to too much power
and achieves the condition of blocking load. It is recommended to break the material into small pieces and not break the material with glue.
Check whether there are many scraps of
paper stuck on the cutter from the paper
outlet.
Pull out and push into the trash can or press the positive and negative buttons
for 3-5 seconds to clean, and confirm again whether it is normal after cleaning.
Try to continuously break 2 pieces of special
oil bags to see if they return to normal.

alarm if the paper is not caught for three consecutive times.
Mechanical full paper,AUTO rod stuck or mechanical
full paper, micro switch shrapnel deformation.
Contact customer service to replace the nose.
Disable one of the shredders
and confirm again.
Machine back to normal.
Although this machine has nominal shredding and automatic
continuous shredding two functions, but can not shredding too much
paper simoutaneously.
Confirm whether the friction piece is not pasted in place, causing a bulge, resulting in the fall of the assembly seat between the friction piece and the
friction piece to form a difference step, the top of the step to the edge of the paper can not be broken; Remove the friction seat, make sure that the end
face of the friction sheet into the paper is lower than the upper surface of the friction seat, and paste it again.
Friction sheets are not pasted well resulting in steps,
prevent paper from being shredded, the problem solved.
The light-controlled induction light is
faulty or the circuit is abnormal.
Contact customer service to replace the nose.
Verify that the paper wheel
is properly assembled.
The outer diameter of the paper grab wheel is small,
and the size of the supporting board is not good.
Push the paper wheel to both ends of the guide rod with your fingers to
ensure the middle position of the guide rod in the paper wheel.
Wet paper makes it difficult to cut. It is recommended to reduce the number of
pieces of paper each time to ensure the effect of shredding damp papees.
Check whether it is the long strip of
paper broken out of the edge of the knife.
The tool is bad, replace the whole machine
Due to the extrusion of scraps on both sides of the tool, there are some long strips,
but the maximum scrap area is in line with the new German industrial standard 66399
, which is a normal phenomenon.
