-Unscrew screws K1 and remove cover M1 (Fig. 8).
-Loosen screws N1 (Fig. 6), adjust the blade and
retighten the screws which hold it, then remount the
cover M1.
ATTENTION!
-The space between the saw blade teeth and the
separator blade should never exceed 5 mm (Fig. 6).
-Use only saw blades with a body thinner than the
blade thickness (2.5 mm) and teeth thicker than this
thickness.
7. CUTTING OFF APPLICATIONS,
REQUIRED WORKING CONDITIONS
This machine model efficiently and accurately cuts off
wood and plastic workpieces, and aluminium profile.
ATTENTION!
-It is essential to use clamps (see Section 10) for
cutting off of aluminium profile, plastic and long
workpieces (Fig. 24).
-Do not start cutting until the blade is spinning at its
full speed.
7.1 CUTTING AT 0° x 90°
Set the rotating plate to 0° using the S index on the
table and the head to 0° using the index on the rear
swivelling side (Fig. 9 and 11).
7.2 CUTTING AT 0° x 45°
Set the rotating plate to 0° using the index on the table,
loosen knob P and set the head to 45° with the index
on the rear swivelling side (Fig. 11 and 12).
Retighten knob P at the setting selected.
7.3 CUTTING AT 45° x 90°
With the head in a vertical position, raise trigger R
(Fig.13) and turn the plate until index S of the table
indicates 45° or any other intermediate angle desired
(Fig. 13 and 14).
7.4 CUTTING AT 45° x 45°
Raise trigger R (Fig. 13) and turn the left plate to 45°.
Release the trigger to lock the machine. To set the plate
at intermediate settings without a fixed lock, tighten
knob G1 (Fig. 16) at the desired setting. Loosen knob
P (Fig. 10) and swivel the head to 45° or to any inter-
mediate angle desired and retighten the knob.
ATTENTION!
-Do not turn the plate towards the right with the head
swivelled as the machine is equipped with an internal
mechanism that prevents this movement.
-Make sure that the swivelling head is perfectly set in
position when chamfering.
7.5 FINE PRECISION CUTS
When cutting off thin or brittle wood, the use of an
auxiliary wood ruler is recommended (Fig. 17). The
machine is equipped with a ruler M (Fig. 7) for this
purpose, as well as nuts N with M4 threads to hold the
auxiliary ruler. This provides a proper support base in
the cutting area of the saw blade in order to prevent
the material from breaking and cutting residue from
flying out behind the saw blade.
7.6 CUTTING WORKPIECES IN SERIES
To perform repetitive cuts of a fixed length, mount the
adjustable side stop assembly F (Fig. 2) on the ruler
guide on the desired side of the machine, adjust and
set its position with knob G. The stop for the length to
be cut can be set with the knobs on this assembly.
8. CUTTING ON THE UPPER TABLE,
REQUIRED WORKING CONDITIONS
(TM72C and TM73C models only)
ATTENTION! Only wood or plastic can be cut on the
upper table. Do not use for aluminium or profiles.
To use the machine in this cutting mode, the machine
must first be fitted with the lower screen D (Fig. 5) to
prevent any accidental contact with the saw disc below
the table. Fit the right-hand side of the fairing on to
the machine first, followed by the left-hand side. Once
both parts are fitted on, proceed to join them using
closure clamps D1 (Fig. 5). Then lock the machine
in transport setting with knob E (Fig. 4), making sure
that the cutting screen is perfectly fitted and station-
ary. Loosen knob Y, remove the upper ruler U (Fig.
4) that houses the blade protective cover and use it
as a side cutting guide, locking it at the desired blade
distance (Fig. 20).
Use the upper ruler as a side cutting guide to obtain
a maximum strip width of 148 mm. This ruler contains
a slit on the side which has two nuts V (Fig. 18) and
can be used to hold a wooden strip that reaches the
vertical axis of the middle of the saw blade. It is a
good idea to mount this strip (Fig. 20) when cutting
short workpieces (dowelling and stubs) since, with
this kind of cut, the cut piece is held by the rotation of
the blade which could cause the piece to be expelled
forcefully as it exits the blade centre if there is insuf-
ficient clearance at the outlet.
Use the adjustable square X (Fig. 19) to cut any angle
by placing the square in the guides on the table.
The blade outlet with respect to the table can be
adjusted by loosening knob T (Fig. 4) and raising or
lowering the table to the desired cutting height, making
sure that the blade exceeds the material to be cut by
the height of the tooth. Tighten knob T tightly at the
selected cutting height.
Once cutting on top of the table has been finished,
place the upper ruler U once again in its protective
position, prior to using the cutting off function of the
machine.
ATTENTION!
-Do not use the upper table without putting the suction
fairing in place.
-Never work without the upper protective cover.
-Replace the separator blade when it is worn.
-Do not use the machine to make grooves or blind cuts.
-Use the pusher Z1 (Fig. 18) to feed the workpiece
through the saw blade.
-Use the upper blade protective cover correctly.
