4.6 Noise emission
The specified values are emission values and therefore
do not represent safe workplace values. Even though a
relationship exists between particle emission and noise
emission levels, an inference cannot be made about
whether additional safety measures need to be imple-
mented. Factors which can significantly affect the emis-
sion level that presently exists at the workplace include
duration of the effect, characteristics of the workspace,
and other ambient influences. The permissible workplace
values may also differ from country to country. Neverthe-
less, this information is provided to help the operator
better assess hazards and risks. Depending on the loca-
tion of the machine and other specific conditions, the
actual noise emission values may deviate significantly
from the specified values.
Note: To keep the noise emission as low as possible, always use sharpened tools and operate the
machine at the correct speed.
Ear protection must always be worn; however, such
protection cannot be considered a substitute for properly
sharpened tools or the correct speed.
As per ISO 3744/94 - ISO 7960/95 Annex norms:
Idle functioning without
dust extractor:
Medium level of
acoustic pressure
Level of acoustic pressure of

Operating mode 74 Decibel (A) 73 Decibel (A) 74 Decibel (A)
4.5 Particle emission
The machine was tested for particle emissions according
to DIN 33893. The Wood Authority ascertained,
according to the “Principles for Testing Particle Emis-
sions” (workplace-related particle concentrations) of
woodworking machines, that the particle emission values
for this machine are notably below the currently valid
atmospheric limit of 2.0 mg/m³. This is certified by the
blue label “BG Wood Particle Tested”.
Note:
Flush trimming is the only operation which produces dust emission. Connecting the machine to an efficient
dust extractor system, which guarantees a speed of at least 20m/min. to the suction outlet, results in dust
emission values below the limit of 2mg/m³ as prescribed by current legislation.

5.4 Compressed air supply connection
The filter/pressure regulator with outflow of condensation
and a lubricator together with quick fitting are located
on the right-hand side of the machine. The fitting is for
10 mm ext. diameter pneumatic hoses (Type RISLAN).
Ensure that the compressed air reaches the connecting
area at least 7–8 bars and that the pressure is free from
humidity and has been suitably filtered.
The length and the inside diameter of the pneumatic
hoses must be proportioned for a correct functioning of
the CRM.
Adjust the air pressure to 6.5 bars.
The machine is adjusted and tested with this pressure.
Minimal power of the compressor: 3 HP
Note: Before proceeding to any maintenance operation, it is necessary to disconnect the
compressed air system.
Attention!
NEVER supply the CRM using a pneumatic
hose with an internal diameter measuring
less than 4 mm.
Attention!
Never add lubricant oils in the condensation collecting cup C.
Fill up periodically the oil cup D fig. 2.3.1 with the
following kind of oil: -SAE #10
Adjust the lubricator F at 2 drops per minute. To outflow
the condensation it is sufficient to push upwards the tap
C with the filter/regulator under pressure.

6.3 Panel positioning
Raise the panel locking unit T by slackening the handle
S.
Place the panel against the fence C and against the
adjustable stop U.
Lower the panel locking unit T leaving it 5 mm higher
than the panel to allow to move it.
Tighten the handle S.
The working stroke of the panel locking cylinder is
10 mm. If the panel locking unit is set too high then the
panel is not locked correctly.
The panel locking unit locks the panel when the pedal H
is pressed and it unlocks the panel when the pedal H is
released.
The adjustable side stop U can be moved to place the
panel in the right position in accordance to the cutter-
head.
The adjustment can be changed by setting the knob E.
Turn the knob clockwise to push the panel off the cutter-
head, in this way the flush trimming decreases.
Turn the knob anticlockwise to put the panel near the
cutterhead, in this way the flush trimming increases.
This adjustment is equipped with a numerical indicator.
Attention! If the cutterhead is changed with a new one it is necessary to set the numerical indicator again!
When the corner rounding process is satisfactory,
slacken the locking grain of the index ring of the indica-
tor. Turn the index ring until the numbers of the indicator
correspond to the corner rounding process.
For example, corner rounding on 2 mm edge, the
numerical indicator has to show “002.0”.
Figures 3.3.3 and 3.3.4 explain the function of the „U“
side stop.

6.4 Corner rounding unit adjustment
The unit flush trims the excess of edge from straight or
shaped profiled panels.
By pressing the pedal H, the following sequence starts:
1. The flush trimming pneumatic motor starts and the
cylinder O moves the trimmer to the panel. The pneu-
matic flush trimmer motor uses a 2-knife cutterhead
that trims off the excess of edge and a copying ball
bearing that traces the surface of the panel. The pres-
sure of the cylinder O is set to avoid the copying ball
bearing from damaging the panel.
2. the cylinder M allows the flush trimming unit to rotate
from the top of the panel to the bottom executing the
corner rounding function.
3. releasing the pedal H, the flush trimmer moves away
from the panel, the cylinder M moves back into start-
ing position and the clamp releases the panel.
4. The ERM is ready for a new cycle.
By moving the handle L2 to the left, the rotation will be
limited to the top side of the panel. By moving the handle
L1 to the right, the rotation will be limited to the bottom
side of the panel. Before setting the handles L1 and L2,
always switch off the compressed air.
The fine adjustments LA and LB allow you to adjust the
starting and end point of the rounding. In this way it is
possible to join properly the radius of the milled edge
with the radius of the rounded corner. L1/L2 Release,
LA/LB Set, L1/L2 clamp again.
LA: Starting point
LB: End point
Look at the figures above for examples of handle settings
depending on the profile to be machined. Points A and
B represent the start and the end of the corner rounding
process. The speed of the rotation of the flush trimming
unit can be adjusted in accordance to the thickness of
the edge. To attain the best results, it is recommended
to reduce the speed of rotation when working with edge
material 2 or 3 mm thick. The speed of rotation can be
reduced with the regulator, loosen to decrease the speed
and tighten to increase it.

7. Maintenance
7.1 Cleaning
7.2 Lubrication
Machines needs to be cleaned periodically.
Always disconnect the compressed air power supply
hose.
● Clean glue residuals from the cutters of the
cutterhead.
None of the mechanical movements require lubrication.
The pneumatic flush trimmer motor requires daily lubrica-
tion.
● Clean fence C and stop U.
● Remove any dust and shavings from the extraction
hood, if necessary.
Note: Adjust the lubricator F at 2 drops per minute.
The pneumatic flush trimmer motor does not need to be
dismounted for lubrication but it is sufficient to fill the
lubrication cup D with this oil: -SAE #10
