Similarly, to trim edges using the D.18 straight bit, also
supplied with the machine, turn the head to the maximum
91.5°, so that the cutting edge of the bit is 1.5° below the
head horizontal (Fig. 9).
6.2 ADJUSTING THE HEAD
WITH REGARD TO THE CUTTER
Disconnect the machine from the power
supply before adjustment.
For the cutter head: The head is set at the required height
by loosening knob D (Fig. 7), turning wheel Y (Fig. 7) until
the required position is reached and it is then fixed there
using knob D (Fig. 7).
The head is also supplied with a high-precision micrometric
adjustment system on its shaft for making fine adjustments
to cutting depth with screw A (Fig. 7). To adjust it in this
way, loosen knob D (Figs. 7 and 2) and using screw A
slowly turn until the required measurement is obtained.
On the side of the machine there is a reference guide in
millimetres G1 (Fig. 7).
For the cutter edge: It also has a fine adjustment system for
the position of the head using screw B (Fig. 7). To use this
adjustment, loosen screw E (Fig. 7) and slowly turn screw
B to the required position.
6.3 AJUSTING THE COPYING SHAFT TO TRIM
Disconnect the machine from the power
supply before adjustment.
In order to set the wheel on the copying device at a suitable
distance from the base of the head, loosen screws H (Fig.
8), raise or lower the copying device to the required height
and fix it again in this position.
To locate the cutter, set the distance to the edge of the
copying device wheel, loosen screw M1(Fig. 8) and set the
position of the wheel using adjustment nut F (Fig. 8).
7. STARTING
To start the machine, press button R forward (Fig. 10) to the
on position. To stop the machine, simply press the back of
the switch and it will return to the off position.
The electronic control enables you to work at the ideal
speed for each type of job and bit. Adjust the speed using
button A1 (Fig. 2).
8.APPLICATIONS
The many options with the tilting head and the included
accessories give the FR1292T a great deal of versatility
to perform such jobs as trimming, slotting, chamfering,
moulding, copying, etc.
8.1 TRIMMING SURFACES AND EDGES
WITH THE 90° CONICAL BIT
Trimming the coating of a surface (Fig. 11-a1), and
(Fig. 13):
• First set the head to 46° (Fig. 13), as described in section
6.1.
• Loosen screw E (Fig. 13), raise the head so it just reaches
the top limit without forcing, by turning knob B (Fig. 13)
clockwise, and fix it in this position.
• Position the base of the head approximately in the middle of
the bit edge by loosening knob D (Fig. 13) and with the help
of control Y and the fine adjustment knob A (Fig. 13).
• Position feeler M (Fig. 13) so that the bearing is near the
bit and fix it in place using the screws H (Fig. 13).
• Adjust the position of the bearing, aligning it with the
bit, using nut F (Fig. 13) and fix in place with screw M1
(Fig. 13).
• If the board is made of particularly coarse fibreboard,
you can use a large support surface lateral square instead
of the bearing feeler. This will prevent irregularities in the
board extending to the trim.
• Trim the excess covering from the surface.
Straight edge trimming (Fig. 11-b1) and (Fig. 14):
• Loosen screw E (Fig. 14) and lower the head by turning
knob B (Fig. 14) anti-clockwise, until its base is aligned with
the bit. Then tighten it in the new position. If knob B (Fig.
14) has been turned as far as it will go and the bit is still
not aligned with the base, do not force the knob; loosen
knob D (Fig. 14) and lower the base of the head, with knob
A (Fig. 14), until aligned.
• Trim the excess edge.
Trimming chamfered edges:
• Chamfered edges may be trimmed to any angle from 5°
to 45°. To do this, loosen the screws N (Fig. 14) and turn the
body to the angle marked on the indicator, i.e. 45°, plus the
required chamfer. Then tighten the screws N.
E.g.: To trim a 30° chamfer, the head must be inclined until
the indicator marks 75°, or 90° for a 45° chamfer.
• Loosen screw E (Fig. 14) and lower the head by turning
knob B (Fig. 14) anti-clockwise, until its base is approxi-
mately in the middle of the bit edge. Then tighten it in
the new position.
• Adjust the position of the feeler bearing, using nut F (Fig.
13) to obtain the required chamfer depth. Hold in place
with screw M1 (Fig. 13).
• Trim the edge chamfer.
8.2 TRIMMING SURFACES AND EDGES
WITH THE D.18 STRAIGHT BIT
Trimming the coating of a surface (Fig. 11-a2): First attach
the D.18 cylindrical bit, as described in section 5.1.
Attach the required cutter, using knobs D and Y the fine
adjustment A (Fig. 7).
Set the height of copying device M (Fig. 7), until the wheel
is on the edge and fix this position using nut F (Fig. 7), so
that the cutting edge of the cutter is flush with the edge
of the piece (Fig. 7).
With particularly coarse fibreboard, you can use the large
