4. GENERAL DESCRIPTION
OF THE FR1156T TRIMMER
The main function of the machine is the finishing of PVC,
melamine and wooden edges. These may be straight and
angled or curved, depending on the bit used. Shaped
finishes can also be obtained using different VIRUTEX bits
with bearings. The machine is fitted with a dust collector
connection for attaching our AS182K and AS282K dust
collectors or any other industrial dust collector, using
the standard dust collector attachment (Ref. 6446073).
The dust collector connection incorporates a sprung
brake pivot R (Fig. 8), whose purpose is to slow down
the outer bearing ring, preventing it turning with the
bit and possibly damaging the surface of the panel when
placing the trimmer in the working position.
5. ADJUSTMENTS
Unplug the machine from the electrical
outlet before making any adjustments.
To adjust the bit outlet, loosen knob B on the head and
turn the machine as appropriate up or down until the
desired bit outlet is achieved. Fasten knob B in place
again (Fig. 3).
6. STARTING UP THE MACHINE
To start the machine, press button E forward (Fig. 1) 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 K (Fig. 2).
7. CHANGING THE BIT
Disconnect the machine from the power
supply before this operation.
Loosen knob B (Fig. 3) and remove the head. To change
the bit (Fig. 4), block the motor shaft using key C, unscrew
the chuck with key D and remove the bit.
Insert the new bit into the housing and hold it in place
using the service keys, then fit the head back in position.
Make sure that the collet diameter mat-
ches the shank of the bit to be used.
Never use the machine without fitting
the head first.
8. CHANGE OF THE TRIMMING HEAD BASE
Disconnect the machine from the
power supply before this operation.
The machine is delivered from factory with the
trimming head base d.20 for bits of 3 mm radius. When
working with a bit 6 mm radius it will be necessary
to change this base for the one d.26. If a bit 8 mm
radius is used the standard base must be replaced for
the one d.30. Both extra bases are included as standard
equipment with the machine.
To change base M, first remove the dust collector
connection L, by unscrewing knob N (Fig. 7). Once
connection L has been removed, unfasten screws P to
remove base M and fit the appropriate base for the
bit you are going to use. Next, fit the dust collector
connection L by screwing in knob N.
9. TRIMMING CORNERS
The support accessory 5646343 included with FR1256T
enables the corners of boards to be trimmed with the
same tool. (Fig. 10)
10. MAINTENANCE. CARBON
BRUSHES AND COMMUTATOR
Disconnect the machine from the power
supply before any maintenance operation.
Remove screws F (Fig. 5) that fasten the side covers and
detach both. Remove the brush-holder I (Fig. 6) with
small screwdriver H, using one of the brush-holder side
tabs to lever it out. Push back the end of spring J. Keep
it in this position to extract the brush and replace it
with a new genuine VIRUTEX brush. Reinsert the brush-
holder, ensuring that it is firmly positioned in the casing
and that each of the brushes exerts a small amount of
pressure on the collector. Re-attach the covers G with
the corresponding screws, making sure that no wires
get caught in the process. Mount the springs and cap
as already indicated above. It is advisable to run the
machine for 15 minutes after changing the brushes.
Should the commutator show burnings or scratches it
