Mode d’emploi
- 33 -
When fitting the blade, ensure that the
hard metal teeth do not come into contact
with the metal parts and that the direction
of the teeth corresponds to the direction
indicated by the arrow on the fixed guard.
Refit the outer flange, as follows:
Turn blade shaft
A
(fig. 7) so that the hole for
insertion of the outer ring nut pin is in a visible
position.
Position the outer ring nut, making sure that pin
B
(fig. 7) fits into the hole on the shaft.
Reposition and fasten the blade casing.
Refit the blade guard in closed position.
Tighten backstop
C
for the end of the opening
stroke (fig. 5).
Refit the head of the rod in its seat and secure it
in place with backstop
A
(fig. 5).
Refit the sawdust conveyor (fig. 4).
CAUTION!
Make sure the upper guard is in
an operating condition before starting any
operations. It is recommended to carry out
a no-load test (without any pieces) by lift-
ing and lowering the cutting head whilst
the machine is running.
CAUTION!
Wear work gauntlets when
handling materials and tools.
CAUTION!
Never fit cracked tools. Use
only tools for wood-working complying with
the EN 847-1 standard, whereas for alu-
minium and PVC use special tools.
8.2 Adjusting tightness of transmission
belts
CAUTION!
This operation must be per-
formed with the machine halted and un-
plugged.
To replace or tighten the belt, proceed as follows:
Remove the belt casing fixing screw (fig. 9).
Loosen the nuts that secure the motor in place.
The slots on the support arm allow for the belts
to be slackened or tightened.
Place the belt onto the pulleys.
Check tightness of the belt by applying, halfway
along the belt section, a force of 1 kg. Make sure
that the belt bends by 4 mm (fig. 11).
Refit the belt casing and secure it in place with
the self-locking nut.
8.3. Adjusting blade stopping time
The brake lining
A
(fig. 13) is subject to wear de
-
pending on machine use. When the gap between the
magnets
B
(fig. 13) and
C
(fig. 13) is excessive, the
machine is braked even when operating, which may
cause overloading and damage the motor, in addition
to excessive wear of the brake lining.
If the blade does not stop within the established
time, adjust as follows:
Remove the fan cover paying attention not to
lose the screws.
Using a hexagonal wrench, tighten the screw at
the centre of the fan until the gap between the
magnet and the keeper is around 0.2 ÷ 0.4 mm.
Refit the motor fan cover by pushing it towards
the motor. Make sure that the blade stops in 5 ÷
7 seconds.
CAUTION!
This operation must be per-
formed only after disconnecting the ma-
chine from the power supply line.
CAUTION!
Replace the keeper when the
consumption of friction material exceeds
1.5 mm. This operation must be performed
by trained personnel.
8.4 Adjusting the arm return spring
If the spring device is working correctly, the arm will
return to its top-most position (end-of-cut position)
without the aid of the operator and at a reasonably
low speed so as to prevent the risk of overturning.
CAUTION!
Adjustments must be made by
trained personnel that has been authorised
by COMPA TECH. S.r.l.
If the blade arm does not return to its top-most
position as described above, check that:
The suction pipe is not preventing movement.
The mobile parts of the saw arm are not colliding
with external structures (positioning conditions
hould be respected).
The suction pipe maintains its flexibility.
All mechanical parts are clean and that there are
no build-ups of shavings.
CAUTION!
Overloading the spring could
generate sudden and unexpected stress
that may irreparably damage the latter.
Compa Tech S.r.l. will accept no responsibility in the
event of improper adjustment or adjustment per-
formed by unauthorised persons.
