- Turn off the engine before topping up the tank with
petrol.
Saws with endothermic engines must be used in the open air. If they
have to be used in closed environments, the openings must be provided
to conduct gases from the engine’s exhaust pipe to the outside using
appropriate non-flammable flexible tubes.
These must be checked for leaks and breakages at the beginning of
every shift.
- Do not start the machine with the blade in the workpiece.
When the saw is not being used, turn the petrol cock to the OFF
position.
10.1 STARTING ROTATION OF THE CUTTING WHEEL.
Gradually move the lever (ref.19; fig.1) so as to bring the motor
revs up to normal working speed and start the wheel turning at
the cutting speed foreseen.
11. STARTING THE MACHINE
Before cutting:
1 – Check that there is enough cooling water in the tank.
2 - adjust the flow of cooling water by turning the cock next to
the blade guard (do not perform cutting without water).
3 - Ensure that blade rotation corresponds to the indications on
the blade guard.
4 – If everything is in order, work can begin.
12. EMERGENCY - STOP
-
In an emergency, stop the machine by pressing the
stop control switch (ref. 7, fig. 1).
13. BLADE INSTALLATION (Fig.5)
By means of a hex wrench no.10, unscrew the 5 screws that lock
the moving blade guard (ref.3). Loosen the locknut (rif.1) by rotating
clockwise (left thread). Remove the mobile flange (rif.2) and check
that the flanges, disc shaft and blade are not damaged.
-
Never use worn blades or blades with missing segments.
- Only use blades that are designed for the number of
revolutions indicated on the machine rating plate.
- Check that blade rotation corresponds to that indicated
on the blade guard.
Centre the blade against the fixed flange, position the mobile flange
and tighten the blade locknut fully down by rotating anticlockwise
(left thread). Refit the moving blade guard, tightening the 5 screws
(ref.3).
- Ensure that the blade guard (ref.3) is locked
securely into position.
- WARNING! An incorrectly installed blade, or a
screw insufficiently tightened can provoke damage to
the machine or injury to persons.
- Note that the blade must have an
external diameter of 500 mm, a central
hole diameter of 25.4 mm and max.
thickness of 3 mm.
- Check that the blade to be used is
suitable for the material to be cut.
- Do not use blades for wood! (fig. 6).
14. USE
- Leave a space of at least 150 cm
around the machine to operate in full safety.
- Do not allow other persons to approach the machine during cutting.
- Never use the machine in fire-risk areas. Sparks can cause fire or
explosions.
- Make sure that the machine is switched off before positioning or
handling.
- Always ensure that the blade is free of any contact before start-up.
- Ensure correct installation of all protective devices.
- Before starting work, fill the water tank. Top up during operation
whenever necessary: N.B.
the pump suction hose must
always remain immersed in water.
- WARNING! For safety purposes the removal of
protective guards from the machine is strictly prohibited.
-
WARNING! Always switch off the machine before
carrying out blade adjustment.
Loading and unloading pieces on the machine cutting table. To avoid
the risk of accidental contact with the cutting wheel, the pieces must
be positioned and removed from the carriage with the cutting wheel
stopped. This is done by adjusting the lever (ref.19; fig.1) so as to
reduce the revs to minimum, thus disengaging the clutch.
14.1 VERTICAL MOVEMENT OF THE DISK.
To raise or lower the cutting wheel, turn the crank (ref.11, fig.1)
until the wheel is at the required height above the cutting table.
The wheel can also be lowered by pressing the pedal (ref.16,
fig.1); when the pedal is released the cutting wheel will return to
the position originally set using the crank.
-
Ensure that the locking handle is tightened fully
before starting work.
14.2 POSITIONING FOR 45° CUTS.
To machine a 45° cut, it is necessary to use the 45° support.
Place the 45° support on the cutting table in the position required,
fix the support to the carriage by locking the flywheel provided,
then position the piece to be cut, after which it is possible to start
the motor and commence cutting operations
14.3 CUTTING
For safe use of the machine when cutting, push the carriage
forwards as the cut advances, placing your hands to the two
sides of the carriage. Never push directly on the piece to be cut.
-
Check that the blade is aligned with the cutting line.
- Place the workpiece on the worktable (ref. 8, fig. 1), resting
firmly against the stop.
- Start the engine.
- Wait until the water reaches the blade.
- Begin cutting.
- Horizontal cutting movement is carried out by pulling the carriage
towards the blade.
-
As cutting thickness increases, the blade is
subjected to greater stress. To avoid overloading the
engine, the operator should continually check blade
feed speed. The speed wi ll also depend on the
characteristics of the material being cut (hardness,
toughness etc.).
14.3.1 CUTTING WITH CUTTING WHEEL LOWERED
FROM ABOVE.
Adjust the vertical height by turning the crank (ref.11, fig.1),
position the piece to be cut, start the panel saw and commence
cutting operations by pressing the pedal (ref.16, fig.1) to lower
the wheel from above.
14.3.2 BLADE CHANGE
To change the blade refer to section 13.
15. USING 550 DIAMETER CUTTING WHEEL.
If an optional cutting wheel diameter 550 mm is used instead of
the standard wheel diameter 500 mm, it is important that the
stop bolt be calibrated to prevent interference between the
wheel and the carriage when the head is in the lowest position.
- Warning. The panel saw is fitted with a stop bolt to
stop the cutting wheel in the lowest vertical position.
This stop is calibrated for a 500 mm cutting wheel. If you
are using a 550 mm cutting wheel, loosen the bolt (ref.
17, fig. 1), lower the wheel to the lowest position, by
turning the crank, then check, with the motor turned off,
that there is no interference between the cutting wheel
and the piece holder carriage when the pedal is pressed.
Adjust the bolt, bring it into contact with the stop and
tighten the lock nut.
- Note that the blade must have an external diameter
of 550 mm, a central hole diameter of 25.4 mm and max.
thickness of 3 mm.
