ning screws Y (Fig. 8) and move it by turning the fine
adjustment knob Z (Fig. 8) until the edge of the bit J
(Fig. 8) is flush with the adjustable lateral guide, turn
the bit 360°. Ensure the precision of this alignment by
using a support ruler A1 (Fig. 8). After determining the
correct position of the bit, once again tighten the two
nuts Y (Fig. 8).
Ensure a perfect finish of the concave radius and the
corner before the final radial trim by first making a
smoothing trim in several runs if necessary, pushing
lateral guide T (Fig. 8) forward to do this.
6.3. Corner trimming (E3, Figs. 5 and 6)
It is recommendable that the corner of the joint between
front and side rims be trimmed before the radius of the
rim with the worktop. Perform corner trimming of the
joint between the worktop and the rim by detaching
the extra feeler U (Fig. 1). Remove the screws X (Fig. 1),
with the aid of a no. 3 allen key.
The machine must be in a 45º position against the base,
with the edge of the bit J adjusted to the base of the ma-
terial V (Fig. 7) and the adjustable lateral guide T (Fig. 8).
Trim the corner with a smooth and gradual descent of
the machine until the previously adjusted trimming
depth rod O (Fig. 4), presses against the step of the
revolving stop turret W (Fig. 4). The maximum run of
the machine is 100 mm.
Before the final corner trimming, lateral guide T (Fig.
8) should be adjusted with the edge of the tool, as
explained in section 6.2.
6.4. Corner-rounding
For better corner protection, fit extra feeler U (Fig. 1),
with the same radius as the rim, using screws X (Fig. 1)
and with the aid of a no. 3 Allen key.
Make successive smoothing runs of the radial material
by first moving nut L (Fig. 4) upwards a few millimetres
and tightening it with the locking nut, loosen locking
lever K (Fig. 4) so that the machine can be raised and
use the fine adjustment knob Q (Fig. 4) to move the fine
adjustment rod to the height of the first smoothing run.
Bear in mind that each full turn of the knob Q from
"0" to "0" represents 1 mm of movement in height of
the stop R (Fig. 4).
With the stop at the required height for the first
smoothing run, move the machine until the stop R (Fig.
4) of the rod O (Fig. 4), presses against the revolving stop
turret W (Fig. 4). Lock the machine in this position with
the locking lever K (Fig. 4) and make the first smoothing
run of the trim radius.
For successive smoothing runs, place the adjustment
knob Q (Fig. 4) in the position for each one and proceed
as described above.
To make the final radial trim, adjust lateral guide T (Fig.
8) with the edge of the tool, as explained in section 6.2,
and place the depth rod O (Fig. 4) back in the previously
12
determined position by using the fine adjustment knob
Q (Fig. 4).
Unlock the bar K (Fig. 4) and move the body of the
machine to the stop. Make sure the machine is secure
in this position for the last trim run by tightening the
two nuts and lock nuts L and M (Fig. 4), one firmly above
and the other below the machine body with the aid of
the two spanners N (Fig. 4).
In this position, the bit will be flush with the base and
the rim and the final radial trim can be performed safely.
Before final trimming of the radius on the worktop,
make a test run to check that the height of the bit and
the position of the adjustable lateral guide have been
adjusted correctly.
7. USE AS A SURFACE ROUTER
The machine can be used as a surface router to repair
the surface of mineral material and for many other
applications such as profiling edges, copy milling, lowe-
ring or engraving surfaces. As a surface router it is an
extremely useful machine as its design allows working
in any position and from different angles.
7.1. Locking the trimming depth
For repetitive work, where the depth of the trim is always
the same and where it is useful to avoid releasing the
head through involuntary movement of the locking lever
K (Fig. 4), the head can be fixed at the desired depth by
placing the two lock nuts L and M (Fig. 4) on the shaft,
threading one above and one below the head and thus
it to be blocked at any point along the depth setting.
When working with the trimming depth
blocked, the tool is permanently off the
surface of the base. This requires the
following actions:
- Wait for the machine to come to a com-
plete stop before placing it on its base on
a flat surface in such a way that the tool
does not come into contact with the surface.
- Remove the nuts to return to normal
locking conditions using the lever K as
soon as the work is completed.
7.2. Making deep cuts
When performing cuts that are too deep to carry out
with in a single run, we recommend making several
successive runs using the six 3-mm steps on the revolving
depth turret W (Fig. 4).
Lower the machine until the cutting bit is level with the
surface on which the trimmer is resting. Use the locking
knob K (Fig. 4) to set the machine in this position. Loosen
fastening knob P (Fig. 4) and lower the depth rod O (Fig.
4) until it presses against the lower step of the revolving
depth turret using fine adjustment knob Q if necessary.
