INSTALLING THE CUTTERS
Find shaft "U" of the locking lever (fig. 4) at the front portion
of the machine. Make sure that the notch in the shaft is
aligned with the whole in the locking plate of the spindle
"U". Move the locking lever of the shaft towards the left to
lock the spindle.
Keep the locking lever of spindle "U" correctly positioned at
all times when carrying out the installation or extraction of
the cutters. Do not tighten the clamp's locking nut too much
as this may damage the spindle's locking plate.
To insert the drill, loosen nut "V" from the bushing and insert
the shaft of the cutter into the clamp. Procure that at least 20
mm or half of the length of the cutter shaft is within the
clamp. The cutter may get loose at lesser insertions. Push
the lock of shaft "V" and keep it pushed, and tighten the
clamp's nut "V". Periodically check the tightening of nut "V"
when working.
EXTRACTING THE CUTTERS
Take into account the instructions for "installing the
cutters".
Use the wrench provided to loosen the nut of the bushing
counterclockwise. With the nut loosened, withdraw the
cutter. If the cutter does not fall out by its own weight, pound
the nut softly to release the cutter. Always clean the clamp
and the thread of the shaft of the clamp's nut.
DUST EXTRACTION
It is recommended to use the dust extraction socket; install
the hose at the machine base "S" for a good performance
thereof (fig. 2). (Read the safety instructions in connection
with dust particles that may be hazardous for your health.)
You can purchase a commercial dust extractor that is
suitable for extracting dust particles that are within the
cutting machine.
PARALLEL GUIDE
Position the parallel guide "A" and its guide rods. Take into
account that the two rods have a thread at one of their ends.
The parallel guide is to be secured to the rods by the two
locking nuts (fig. 2).
ROUTER BASE OF THE MACHINE
Router base "O" is connected to the cutter and allows the
machine to follow a special cutting profile. It may be used
with or without the dust extractor.
Remove the three screws which secure the dust suction
outlet. Position the guide bushing at the cutter's base "S".
Secure it by tightening the 3 screws.
All the cutters must be fitted in the guiding platform slot,
whose diameter limits that of the cutter to use.
WARNING: When using the cutter on delicate surfaces as
decorations or finishes, remind covering the decorative
surfaces or those of the cutter base well with adhesive tape
or another protection means.

5.- CARBON BRUSH REPLACEMENT
A. Replace carbon brushes when the machine does not
work, works irregularly or after many sparks.
B. Carbon brushes with less than 5 mm must be replaced.
C. Always replace both carbon brushes; at the same time
use the brush provided by the manufacturer.
D. Rotate covers "E" using a screw driver (black-colored
covers which can be found beside the tool).
E. Take out the worn-out carbon brushes (fig. 17) and
clean the compartments using compressed air.
F. Position the new carbon brushes in the reverse order.
G. Put covers "E" by turning smoothly.
H. After having placed the new brushes, let the tool run for
some minutes to allow the brushes to adjust.
6.- STARTING
Hold the cutter firmly with both hands at the grips.
1.- Push button "M" to start.
2.- For continuing work, lock button "M" by pushing button
"T".
3.- To stop and unlock the machine, push "M".
4.- Wait for the machine achieving full speed before any
works.
5.- To stop, simply release button "M" (fig. 5).
VARIABLE SPEED
Located at the right upper portion of the machine there is the
variable speed button (fig. 6). To increase or reduce the
speed, it is only necessary to rotate the knob. The smaller
the cutter is, the higher is the speed and vice versa. A cutter
rotating to fast or advancing to slowly may burn the work
piece entailing the hazard of fire.
DEPTH ADJUSTMENT
This machine is equipped with a depth stop "H" and a depth
scale "G" allowing a quick selection of the depth. The
magnifier at the register line can also be slid upwards or
downwards to facilitate adjustment and lecture of the depth
scale.
The depth stop and the scale can be moved upwards and
downwards by rotating the knurled adjustment screw "K"
(fig. 7) clockwise or counterclockwise to set the position of
the cutter regarding the work piece or the required cutting
depth, relative to the depth scale by using the locking button
to lock the distance (fig. 7).
