To situate the handle of the machine in the working
position, loosen knob C (Fig. 5), swivel the handle
round to a confortable position for mitering and
tighten up knob C.
5.3 UNLOCKING THE HEAD
Lightly press the handle in the direction of the cut and
turn the transport locking catch D (Fig. 8) clockwise
until it reaches the stop, then follow the machine as
it moves up to until it is locked in resting position.
5.4 CHECKS
Before connecting the machine to the mains supply,
make sure the blade guards and safety mechanisms
are in good order.
Also check that the mains voltage and frequency coin-
cide with those indicated on the machine specs. plate.
In the event of using an extension lead, check that
the cross-section of its conductors is appropriate for
the machine's current rating.
6. ADJUSTMENTS
Make sure that the machine is discon-
nected from the mains supply before
making any adjustments to it.
The cross-cut saw is set before it leaves the factory.
However, the mechanisms mentioned below serve for
making any adjustments at a later stage.
6.1 ADJUSTMENT OF THE FOLD-DOWN HEAD
To adjust the saw blade to 90° in relation to the
machine table, place a square between them both
and proceed as follows:
Loosen the handle E (Fig. 15) and correct any possible
deviation by means of screw F. The head may also be
adjusted when folded down 45° in relation to the
base - in this case, use screw G.
6.2 ADJUSTING THE SWIVEL TABLE
The machine is fitted with automatic fixturing at
0°, 15°, 22.5°, 30° and 45°, so will rarely need to be
readjusted in these positions. If necessary, lock the
machine at 0° and, by loosening the screws H atta-
ching the straightedge I, move the latter until it is
absolutely perpendicular to the saw (Fig. 7).
6.3 ADJUSTING THE MAXIMUM CUTTING DEPTH
The maximum cutting depth is determined by the
adjusting screw K (Fig. 8). This should be readjusted
every time the saw blade is changed or sharpened.
- Check that the saw is not touching the
bottom of the plate once the maximum
depth has been adjusted.
- Change the cover on the plate when
it is worn or broken.
6.4 ADJUSTING THE KEEL
To adjust the keel, proceed as follows:
- Loosen knobs L (Fig. 17) and raise the table as high
as it will go, fixing it in place by tightening the knobs.
- Remove cover M using screws N (Fig. 16).
- Loosen the hexagonal-head bolts securing the keel,
adjust it to its new position and tighten again the
bolts U6 (Fig. 6); then replace the cover M (Fig. 16).
- The distance between the sawblade
teeth and the keel should never ex-
ceed 5 mm.
- Use only sawblades whose body is
thinner than the thickness of the keel
(2.5 mm) and whose teeth are wider
than this thickness.
6.5 ADJUSTING THE UPWARD TRAVEL STOP
Screw P (Fig. 15) governs adjustment of the upward
travel stop, although it is necessary to ensure that
the machine locks into the rest position.
7. CROSS-CUTTING APPLICATIONS.
CONDITIONS OF USE
This machine allows efficient, precise cross-cutting
of timber, plastic and aluminium.
The machine's straightedge I includes some threaded
holes R (Fig. 21) which, on the front, allow rapid
positioning of a wooden chock to avoid tearing of
the material to be sawn. Its double use when cut-
ting fragile materials and fine thicknesses is highly
recommended (Fig. 22).
The use of press devices (see section
10) when cross-cutting aluminium
sections, plastic and long pieces, is
absolutely essential.
Do not start cutting until the blade has
reached its full speed of rotation.
