1.1 FEATURES OF THE MACHINE
In Figure 1 we have provided the UNICO with the designations of
the most important components. Please take a little time to become
with the machine.
1.2 DESCRIPTION OF THE MACHINE
The edge sanding machine UNICO works with a sanding disc wheel,
which is installed in an attachment. Three attachments in various
lengths can be supplied. The housing of the attachment covers the
actual working zone. A machine handle, which is used to guide the
machine when you are working on your knees, can be installed
depending on the length of the respective attachment. Velcro
sealing tape is used to seal off the working zone from the discharge
of dust. The resulting increased flow speed of the air upon entering
the working zone from outside guarantees constant good suction of
the sanding dust. Inside the attachment, there is a running V-belt,
which is driven via the V-belt pulley of the motor installed vertically
on the fan housing. The two guide rollers, which support the rear
of the machine, are also installed on the fan housing. In front, the
machine rests on the sanding abrasive (three-point support). The
fan housing is provided with two additional drilled holes into which
the machine handle can be screwed if and when required. On the
rear side of the fan housing, a rotating pipe bend fitted to a pipe
union conveys the sanding dust into the dust bag. The dust bag is
fastened to the pipe bend by means of a quick fastener.
The dust bag is suspended from the cable support by means of
a textile loop. This textile loop keeps the connection cable away
from the working zone and is inserted in the holder on the pipe
bend of the machine guiding system. This holder also includes
the Allen key, which is required to replace conventional sanding
discs. The pipe bend can be used to guide the machine when you
are working on your knees. An extension including a handlebar is
installed at the front end of the pipe end and can be used to guide
the machine when you are working in a stooped position or in an
upright position. The extension and the handlebar can be adjusted
as soon as the clamping lever has been opened.
The machine guiding system and the switch box are attached to
the motor. An ON/OFF switch including no-volt release as well as
the rotating and swiveling working light is fitted to the upper side
of the switch box.

TECHNICAL DATA
NOTE on noise emission:
The values indicated are emission values
and must not represent safe workplace
values as well.
Although a correlation exists between
emission levels and immission levels, it is
not always possible to determine whether
additional precautionary measures are
required.
Factors that can have an effect on the
immission level existing at the workplace
include the duration of the effects, the
characteristics of the work area and
other sources of noise, e.g. the number of
machines and processing operations in the
vicinity. The permissible workplace values
may also vary from country to country.
This information, however, is intended
to enable the user to better estimate the
dangers and risks.

Fig. 10 Install the Velcro strip carefully to ensure properly
sealing.
Fig. 9 The pressure hose can also be rotated at the lower
plastic pipe stub.
Fig. 8 Inserting the cable support into the proper
bracket.
6Pick up the cable support and hook it into the sling on the
top end of the dust bag (fig. 7).
7Insert the cable support into the proper bracket on the pipe
bend (rear side of the machine) next to the Allen key (fig. 8).
4.2 SWIVELING THE PRESSURE HOSE
For your sanding work, the pressure hose can be rotated toward
the left or right depending whether you standing on the right-hand
side or on the left-hand side of the machine or whether you are
kneeling or bending down. This ensures a constant volumetric flow
of the air being sucked into the machine.
1On the pressure hose, grab the black plastic pipe stub below
the hose piece and rotate it toward the desired side. The dust
bag will swivel with the black plastic pipe stub (fig. 9). Do
not use the upper curved pipe piece to rotate the pressure
hose.
2Whenever appropriate, make sure that the dust bag is
properly positioned without any folds.
4.3 INSTALLING THE VELCRO STRIP
Depending on the thickness of the abrasive in each case, the Velcro
sealing strip on the attachment must be repositioned in order to
improve the airflow conditions at the front end of the attachment
and to seal off the sanding zone from the surrounding area.
1Switch off the machine and pull the power plug out of the
socket!
2Fasten the Velcro strip by one end of the adhesive strip to
the attachment and then place it all the way around the
attachment (fig. 10).
3On the front side of the machine, the Velcro strip should be
about 1 mm away from the floor in order to be able to provide
an air inlet. At all other locations, the strip is supposed to be
resting on the floor.
4The Velcro strip must be renewed whenever it is worn-out.
However, you can, of course, also use the upper edge of the
Velcro strip after turning it over.
