8 WORKING WITH THE MACHINE
Only qualified employees older than 16 years of age may operate the machine
Never put hands into a moving hopper
The results obtained with this machine can only be guaranteed when machine is regularly
cleaned and maintained (see various chapters)
Only use vegetable oils for lubricating the hopper, hopper plate and table. OVAM 25 from the
company Zeelandia is also acceptable. Do not use “squeezed oils” like salad oil because these
often contain resins which build up on and in the machine and will negatively influence both the
operation of the machine and the frequency of cleaning. Also the machines life maybe adversely
affected.
8.1 Basic working order of the machine
1. Oil the hopper and the upper plate lightly
2. Fill the hopper with dough; Fresh dough will give the best weighing results
3. Set the dough weight by turning the weight adjustment wheel
4. Turn on the main switch
5. Check the emergency button is not activated
6. Press the start button
7. Check the weight of the first three pieces while running the machine and adjust the weight
using the weight adjustment wheel accordingly.
8.2 Using the counter
With the help of the counter a specific amount of required pieces can be set. When the counter has
reached the set amount the machine will stop.
1. Current count
a. Press the “->” button, the current status of the amount of pieces is shown while
the led “X” will light up.
b. Resetting this value to zero can be done by pressing the “C” button.
2. Pre-set value
a. The amount of pieces which must be counted; by pressing the “->” button again
the led “P” will light up.

9 WEIGHT ACCURACY
The accuracy of the weight of the dough pieces is dependent on the following items:
- The consistency of the dough. The fresher the dough the better the weight result
- The speed of the machine. The lower the speed the better the result will be.
- Cleaning. If the filter and O-ring are maintained and cleaned properly the results will better.
Table to check the vacuum system
Behind the cover a gauge is mounted where the vacuum pressure can be seen.

10 MAINTENANCE
10.1 Cleaning
The numbers in the text refer to those in figure 3.3 which is to be found on page 7.
Always turn the main switch to “0” (off) before starting any kind of maintenance.
Never clean the machine with water. The use of water will cause oxidation and electrical
problems.
Only qualified employees may clean the machine. Other persons should keep their distance.
Daily:
Cleaning the hopper
1. Remove the 4 bolts from the block with the supplied key 13 and 17 mm
2. Clean the inside of the hopper only with a plastic scraper or sponge
Never use a steel scraper; it will damage the Teflon coating
3. Clean the bottom of the hopper block with a plastic scraper until the surface feels
smooth to the touch.
Cleaning the upper piston and filter
1. Use the special tool supplied with the machine for to unscrew the bolt and upper
piston. Remove the bolt from the upper piston
2. Now use the tool to screw into the bolt hole left by the removal of this bolt, DO NOT
screw this all the way in.
3. Now by pulling on the tool, remove the upper piston from the cylinder.
4. Clean the piston, also not forgetting to clean the sides. Make sure they are smooth and
free from dough pieces.
5. Now remove the filter from the cylinder and, using water in this case, remove any
dough. Soak the filter in a solution of ammonia and warm water for about 4 hours.
6. After soaking rinse the filter thoroughly with warm water to remove any remaining
ammonia.
7. Dry the filter thoroughly and put this back into the machine. Never grease the filter.
8. Replace the upper piston and assemble this using the tool and the bolt.
Cleaning the middle piston
1. Firstly remove the hopper by undoing the four bolts. This makes it easier to access the
middle piston.
2. Disassemble the three bolts visible on the top of the middle piston and the insert the
tool into the centre of the middle piston.
3. Remove the middle piston in the same manner as the upper piston. (See point 2
onwards).
4. Remove the “O-Ring” from the piston with a small pointed object. Be careful NOT to
damage the “O-Ring”.
5. Clean the parts thoroughly with warm water.

Re-assembly of the middle piston
1. Assemble the “O-Ring” to the middle piston and put the middle piston back into the
cylinder BY HAND.
2. Ensure that the “O-Ring” is in the lower piston and that the arrow on the top of the
middle piston points to the out feed belt (the middle piston can only be mounted
one way.
3. Put the bolts back into the piston but do NOT tighten them yet.
4. Ensure that all other loose parts are removed from the machine and let the machine
run for a few cycles. This will centre the piston in the cylinder. We recommend the
lowest speed for this.
5. Once the machine has again been stopped and switched off, tighten the middle
piston bolts down. These should be tightened to “hand tight”. If the bolts are
tightened too much this could damage the threads.
6. Put the filter back and re-assemble the upper piston as already shown above.
7. Re-assemble the hopper and your machine is ready for use.
10.2 Maintenance
Maintenance should only be performed by qualified technicians. Please contact your supplier for
maintenance instructions and assistance.
10.3 Instructions changing out feed belt
The out feed belt should only be changed by qualified technicians. Please contact your supplier
for maintenance instructions and assistance.
