Congratulations to the purchase of the Brunner Industrial Food Processor IR
250. This robust and high-performance machine will achieve you good services
in various applications. The design in total stainless steel makes it especially
durable. It can easily be cleaned after every use. We are sure that the Industrial
Food Processor IR 250 will render you good services for many years and will
confirm the rightness of your investment.
Yet with construction of the industrial grater a lot of safety has been integrated
it is necessary that attention should be paid to certain safety instructions during
operation. Read these precautions attentively.
• While setting up and attaching:
The machine should be placed on an even, firm terrain! Always make sure that
both front wheels are safely blocked. It should be installed preferably near to a
power socket. To avoid a trip over do not lay the cable over a passageway.
• While changing the alternating parts for all applications:
Primarily, always turn off the industrial grater. Before opening the grating box
wait until the drum and blade have stopped moving! To avoid getting finger
caught the alternating parts should be gripped with both hands at the suggested
surfaces. The closed top is to be secured with fastening screw.
• While loading of goods for processing:
Never should foreign objects get into the supply opening. Under no
circumstances, never ever grip into the supply opening! Neither to distribute
grating goods nor to take out foreign objects. In this case the machine is to be
switched off and the grating box completely to be emptied.
• While cleaning:
Dismantle only so far as intended for the operator. The machine is splash water
proofed. If available, the housing may be washed with a high pressure cleaner.
• In case of disturbances: Emergency stop
This should be the first reaction to possible disturbances of any kind: Switch off
the machine ! The power plug must be pulled out of the socket if unpleasant
smells should arise.

The emergency stop button is identical with the normal on-off switch.
It is easily to reach at the right hand side of the motor housing.

Equipment
The equipment contains together with the machine with power cable according
to the individual order the following parts:
• grating- / granulating drum • grating- / granulating wing • set of spanners
• strain drum and wing • ejector • cutting disc
• cutting element • operating instructions

operating instructions
The mobile machine should be placed on an even, firm and not sloping ground
and must be arrested. Therefore the clip has to be pushed down with the foot
until it catches. Sufficient space should be existent for the preparation and supply
of grating goods and the pick up container. The machine can also be disposed
for automatically loading. Therefore the funnel cover with circular port is to be
used. The grating good can such wise continuously be supplied such as through

a channel. The power plug must be installed by an authorized electrician. The
power plug must be plugged into a high voltage current socket. ( 400 V )
According to the application the suitable grating or granulating drum with the
wing has to be installed or to be checked wether the right part is prepared

already. Loosen the fastening screw and swivel the funnel with the cover
backwards as far as the stop. The suitable grating or granulating drum can now
be installed. The drums are marked at the inner top edge of the grating sheet.
Fig. 16
The grating drum is inserted best with two hands. The
designation is for example A-10D.
Fig. 17
The grating drum is fixed with two socket head screws.
It is fixed with two hexagon socket screws and the appropriate spanner.
Afterwards the suitable grating or granulating wing is inserted and fixed with
the central hexagon screw. Make sure that no loose parts remain in the grating
drum or housing. Swivel the top forward to close the grating box. The locking

screw is to be fitted into the fork of the lid and to be fastened by hand. To pick up
the grated goods place a suitable container under the outlet. The machine can
now be switched on. According to the grating goods and availability you can

switch up to level II. The grating goods can now gradually be filled into the
loading mouth. Arrange feeding in case of continuous loading.

The grating wing is inserted and slightly turned until the tappet
snaps in.

The grating wing is fixed by the central hexagon screw.
Open the working area as for grating and granulating. The ejector is installed
first so that the protruding plastic part is facing downwards. Secure these with
two socket head screws and the enclosed spanner. To insert the cutting disc
hold it by the hub. A slight turning ensures a secure click into place of the cams.

Finally, the cutting element is inserted. You hold it most safely on its wings and
insert the stopper in the area of the outlet. The cutting element is attached with
the central hexagon screw. Close the working area by swiveling the top forwards.
Turn up the fastening screw and tighten it by hand. Provide a bowl to pick up

filled in. Arrange feeding in case of continuous loading. According to the good
to be cutted and the availability, the machine can be switched up to level II.
First of all, you have to switch of the industrial grater on the main switch. Unplug
the power plug for safety reasons. Release the fastening screw to open the
grating box and swivel the top backwards to the stop. Dismount the grating /
straining wing or cutting element according to the latest application. All of them

will be released. In case of cutting applications the cutting disc can now be
lifted out on the hub. Depending the foregoing application, the grating / straining
drum or ejector are dismounted as next. All three are secured with two socket

The mounting of the parts after cleaning is to be made analogous in reverse
order. Put the top onto the grating box and push the hinge shaft from the right
through the drilling. Secure the shaft with the knurled thumb screw on the left
end. The further steps corresponds to the setting up of the industrial grater for
a particular grating- or cutting good like described in the chapters «Thus you
grate or granulate» on page 6 or «Thus you cut your cutting good» on page 7.
