User Manual 7
Noise level at the machine
The continuous sound pressure level emanating from the machine is approx. 88.43 dB(A). Depending on
local conditions, a higher sound pressure level can result, causing hearing damage.
In this case, the operating personnel must be protected with appropriate protective equipment or
protective measures.
Notes on the noise specification
The specified values are emission values and therefore do not have to represent safe workplace values at the
same time.
Although there is a correlation between emission and emission levels, it cannot be reliably deduced from this
whether additional precautionary measures are necessary or not.
Factors that influence the current emission level at the workplace include the nature of the workspace, other
sources of noise, e.g. the number of machines and other neigh boring work processes. The permissible workplace
values can also vary from country to country. However, this information should enable users to make a better
assessment of the hazard and risk.

Manual table routing machine
The milling position on the workpiece is
determined by moving the stop elements
and the desired milled groove length is
pre-set using the measuring pin.
The workpiece is clamped by pulling the
hand lever of the machine.
If the hand lever is pulled further down
from this position, the milling unit moves
up.
After the milling unit has reached its end
position on the measuring bolt stop, the
hand lever is returned to its starting
position and the milling process is
complete.

Commissioning and maintenance
Setting up the machine
Remove the transport packaging and clean the machine with a suitable machine cleaning agent
(e.g. WD40).
The machine is set up on a sufficiently stable table. The table plane must be sufficiently large,
evenly flat and level so that the machine is stable.
Electrical connection
Before commissioning, check whether the mains voltage corresponds to the information on the
machine type plate and the type of plate of the milling motor. If all information is correct, connect
the machine plug directly to the socket.
Extraction system connection
The machine type MU-S has an extraction connection on the rear side of the machine.
When working with the machine for a long time, the suction must be connected. The suction
channel leads directly under the milling unit. This means that the suction has a high efficiency,
and the chips are sucked up directly below the milling cutter.
The minimum air speed required for extraction at the extraction nozzle of the machines is 20
m/s for dry chips and 28 m/s for moist chips (humidity >18%).
To do this, an extraction system must be connected that at least achieves the following values:
1.) Minimum flow rate at the intake manifold = 250m³/h
2.) Minimum vacuum at the intake manifold = 14000 Pa

The Hoffmann Frame Joiner system
Due to the extremely precise double wedge shape of the Hoffmann-dovetail, the parts to be connected are pressed together exactly and
permanently due to the forced guidance.
The milling cutter setting dimension must be adhered to exactly for optimal matching.
The correct setting dimension "X" for the
Type W1 be 3,5 mm.
Type W2 be 5,1 mm.
Type W3 be 6,9 mm.
With this setting, the Hoffmann dovetail connector optimally pulls the frame parts together.
The machine is preset at the factory to the customer's router and ensures appropriate
pressure for the types of wood: hardwood and softwood, MDF, chipboard and multiplex.
Incorrect:
If the adjustment is less than the minimum adjustment, no
pressure is generated on the joint surface and a gap is
formed.
That is, the two frame parts are not fully assembled.
Incorrect: Milling depth too great.

Adjusting the routing groove length
The milling groove length of the machine is limited by setting the measuring bolt.
By setting the measuring pin depending on the corresponding workpiece thickness, a
faster work cycle is possible and accidental "milling through" of the workpiece is
prevented.
Groove length adjustment
Open the clamping lever (1) and set the measuring pin to the
desired milled groove length. The set slot length can be read
directly on the ring surface (2) of the motor bracket. Close the
lower clamp lever to fix the setting.

Depiction: machining operation
with the 45° stop plate.
Working with the Hoffmann stop system.
Thanks to the special stop system of the Hoffmann machines, the workpieces
can be precisely milled in different variants. Here, workpieces with different
angles as well as workpieces with radii can be processed without any problems.
The Frame Jointing machines are equipped with a 45° stop plate (1) and a 90°
butt stop (2). By moving the stops, different milling positions can be set on the
workpiece. With the 45° stop plate it is possible "right" and "left" 45° cut
workpieces in a single stop setting to edit. The workpiece dimensions are limited
by the workpiece width, which may not exceed 75mm.
All workpieces that are wider than 75mm or have a different angle or have a
radius are machined with the 90° butt stop. To do this, the 45° stop plate is
loosened and removed from the machine table.
For "right" / "left" processing, the 90° butt stop is positioned alternately on the
right or left side of the machine. The position of the stop at the 90° butt stop
edges is read directly on the measuring tape scales on the machine table. The
milling position(s) on the workpiece depend on the profile and are freely defined
by the operator.
