4.2 Assembling the Saw and the Base
- Join panels A, B, and C by inserting tenon into mortise as
shown in circle diagram 1 and 2.
- Fasten bottom panel D into the joined panels A, B, and C
using setscrews that are provided
- Attach panel F to panel C with provided setscrews.
- Attach control box with two provided setscrews.
- Mount the saw unit on the base as shown in drawing 5.
- Fasten the saw unit to the base with provided set screws.
If the machine needs to be moved in its own packing, use
a forklift truck or sling it with straps as illustrated in
drawing above.
4.3 Minimum requirements for housing the machine
- Main voltage and frequency must comply with the
machine’s motor requirements.
- Environment temperature should fall within –10 ºC to
+50 ºC.
- Relative humidity cannot be over 90%.
4.4 Anchoring the machine
Position the machine on a firm cement floor, maintaining,
at the rear, a minimum distance of 800 mm from the wall;
anchor it to the ground as shown in the diagram, using
screws and expansion plugs or tie rods sunk In cement,
ensuring that it is sitting level.

4.5 Instructions for assembly of the loose parts and
accessories
Fit the components supplied:
Detail 1 Mount bar-stop rod
Detail 2 Mount and align the roll-supporting arm as per the
counter-vise table.
4.6 Deactivation of machine
- If the sawing machine is to be out of use for a long period, it
is advisable to proceed as follows:
1) Detach the plug from the electric supply panel
2) Loosen blade
3) Release the arch return spring
4) Empty the coolant tank
5) Carefully clean and grease the machine
6) If necessary, cover the machine.
4.7 Dismantling (due to deterioration and/or obsolescence)
General rules
If the machine is to be permanently demolished and/or
scrapped, divide the material to be disposed of according to
type and composition, as follows:
1) Cast iron or ferrous materials, composed of metal
alone, are secondary raw materials, so they may be taken to
an iron foundry for re-smelting after having removed the
contents (classified in point 3).
2) Electrical components, including the cable and electronic
material (magnetic cards, etc.), fall within the category of
material classified as being assimilated to urban waste
according to the laws of your local, state, or federal
government, so they may be set aside for collection by the
public waste disposal service;
3) Old mineral and synthetic and/or mixed oils, emulsified oils
and greases are considered hazardous or special refuse, so
they must be collected, transported and disposed of at a
special waste disposal service.
NOTE: The standards and legislation concerning refuse is in
a constant state of evolution, therefore is subject to changes.
The user must keep informed of the regulations at the time of
disposal as these may differ from those described above.

5.3 Vise adjustment
- The device does not require any particular adjustment;
in case of excess play of the sliding guide, tighten slide
screw more.
To move the vise in either direction, the vise jaw must be
unlocked at two points.
- Release the track support by turning handle (1) counterclockwise.
- Release the vise by moving the lever (2) to the left.
- The vise (5) may now be moved to right position (7) or
left position (6) by pushing it with one hand on the vise
and the other hand on the track handle (1).
- Once in position, move the lever (2) to the right to lock it
into position.
- Lock the track support (1) by turning handle clockwise.
Clamping the Work Piece
- Place work piece between the jaws.
- Use the hand wheel to approach the vise jaws to the work
piece, make the vise jaw to against the material. Lock the
work piece by push down the lever (4).
Push start cutting button (D). When the cutting cycle is
finished, release vise by pulling lever (4) up. Upon releasing
the lever (4), the vise jaw will open. This allows for rapid
loading of same size material.
5.4 Cutting angle adjustment
Cutting at angles
- Using the right side, angles can be cut up to 60 degrees.
This requires that vise jaw to be set on the left side (6).
- Using the left side, angles can be cut up to 45 degrees.
This requires the vise jaw to be set on the right side (7).
- Unlock lever (3) and rotate the saw frame arm until you
reach mechanical stop and check if the index corresponds to
45 degrees; if not, operate on the set screws to make
measures meet.
5.5 The base
- A structure supporting the SAW ARM (revolving arm for
gradual cutting and respective blocking system), the VISE,
the BAR STOP, the ROLLER for the support of the material.
The base houses the cooling liquid TANK and PUMP.

The hydraulic cylinder is ideal for the cutting of thin or
stainless steel section bars that determines a constant
lowering and consequently a good efficiency of the blade
throughout the work phase.
By adjusting the flow control valve (A), this device can be
accommodated to the different situations and applications.
(B) level is on/off switch to control hydraulic flow.
5.7 The operation cycle
Before operating, all the main organs of the machine must be
set in optimum conditions.
