switch to turn off the machine.
- follow the cutting head until it is in the resting position.
SaW BenCH MODe
OPERATOR
The normal operator position is in front of the machine, with both hands pushing the
piece towards the blade while exerting slight pressure on the table. During the final
stage, the operator uses the piece pusher with one hand only (fig. L).
Warning! Keep your hands and face far from the blade and cutting area. Serious
injury hazard!
WORK SURFACE
The work surface (pos. 17) must be positioned correctly before starting any operation,
for this reason it can be moved upwards or downwards:
- to the highest position in cutting off mode
- to the lowest position in saw bench mode
It is forbidden to position the surface at an intermediate height.
Lock or release the movement of the work surface by using the screw (pos. 14), during
operations the screw should be well tightened.
Follow the indications reported in the “Operational procedures” chapter carefully
in order to move the surface correctly.
WORK PIECE
The shape, size and weight of the piece to be cut must be compatible with the machine.
Trace the cutting line on the piece with a ruler; place the piece on the machine’s table
(pos. 17) in front of the blade without touching it and rest it sideways against the sup-
porting guide (pos. 19), which you previously adjusted according to the scale on the
work surface. The wider side of the piece must rest on the base; do not cut pieces with
the wider side upright. Do not attempt to cut pieces that are thicker than the machine’s
cutting capacity, the piece would get stuck underneath the guard.
Specifically sized pieces can be used on this machine (thickness H, see Technical
Data). Do not attempt to cut pieces that are thicker than the machine’s cutting capacity,
the piece would get stuck underneath the guard. In order to support long pieces, you
must be equipped with a pedestal to be placed at the back of the machine, this would
prevent the two pieces from tipping over, posing an hazard to the operator. Align the
line traced previously with the theoretical surface the piece shall create with its straight
motion through the blade.
WarnInG! For your safety, it is important that the machine is secured to the bench
or stand.
WarnInG! For your safety, it is important that the piece is correctly locked. Do not
cut circular sections, old or fragile wood, irregular wood, cracked wood, wood with
nails or screws, branches or trunks. always carefully inspect the piece.
WarnInG! always remember that a kickback causes the rejection of the piece,
which is ejected towards the operator.
TOOL
Make sure the blade is integral, without cracks or deformations before use. Periodically
check blade sharpness.
When necessary, replace it following the instructions in the next chapters.
Warning! Blade efficiency and perfect integrity provide better results and minimize
accident risks.
CHIP AND DUST VACUUM
The machine can be equipped with a manifold (pos. 24) for the suction of chips/
sawdust. Please remember that the part of material removed while cutting will also be
thrown around the machine and on the piece. Connect the manifold to a wood chip/
dust vacuum using a flexible plastic hose (neither supplied with the machine); your
local dealer can recommend the best product.
Warning! Do not start the machine if the vacuum tube is not installed. Do not insert
your fingers or tools in the manifold in the attempt to remove material. Serious
injury hazard!
PUSH STICK
Before performing the cutting maintain the pusher at hand. If not used, store it away
from moving parts.
KNIFE DIVIDER
It is a comp onente important for safety and must be adjusted with respect the disc
blade (Fig. N). The thickness of the riving knife must be less than the width of the cut
groove and supeiore to the thickness of the metal disc of the blade.
OPERATIONS, CUTTING AND MOVEMENTS
The blade is fixed to the machine, while the piece moves manually in a straight and
parallel line in relation to the blade.
The engine provides power to rotate the tool, using a set of gears.
Observe the following warnings that apply to all types of cuts:
- make sure that levers and screws are tightened to firmly secure mobile parts
- keep the work piece firmly
- the piece must rest against the work surface (pos. 17) and the piece guide (pos. 19)
- do not cut several pieces simultaneously
- keep safety distance from the cutting area
- gradually and cautiously near the piece to the blade
- cut in a single stroke
- do not force the piece against the blade so as not to strain the blade and the engine
- excessive strains cause the blade and/or piece to suddenly break
- do not strain the blade laterally
- the idle blade should not touch the piece
- do not start the machine if the blade is in contact with the piece
- do not start the machine if the higher guard is not covering the blade (pos.15)
- do not start the machine if the removable guard is not positioned over the blade
(pos. 16) underneath the work surface
- to clean the cutting area, use a brush with a long handle
CUT ALONG THE AXIS OF THE PIECE (fig. L)
Initial position:
- set the machine in “saw bench” mode
- the rotary table (pos. 9) is locked at 0° with the screw (pos. 11)
- the cutting head is fixed at 0° by the lever (pos. 22)
- the piece guide (pos. 19) must be installed on the work surface as shown in fig. L.
Cutting:
- press the switch (pos. 2) to start the machine
- using both hands, push the piece against the blade (enclosed in the guard) at a uniform
speed and, at the same time, press the piece onto the work surface and on the piece
guide. The part will cause the upper guard to lift (pos. 15) and to rest onto the piece
keeping the blade protected
WarnInG! Keep hands away from the cutting area.
- when your hands get closer to the blade, use the piece pusher to complete the cut
- turn off the machine.
BLADE
WarnInG! the cutting part can cause serious injuries – use protection gloves!
- Use good quality blades with the same characteristics as the machine based on its
technical data – your retailer will be able to help you make the correct choice. Also
observe any instructions provided with the equipment.
- Do not use blades if you do not know where they are from or without technical specifi-
cations. They must show the nominal dimensions, the number of teeth, the maximum
number of revolutions and the arrow indicating the rotation direction.
- The number of revolutions and the dimensions are the basic elements for making
your choice. The number of revolutions must always be higher or equal to that shown
on the machine. The dimensions must be equal to those shown on the machine.
- Use blades which conform to the regulations in force in the country of use.
- Do not use HSS (high speed steel) blades or abrasive truncating discs.
- Always carry out a simple visual check: there must be no deformations, breakages
or damages.
- Use only sharp blades.
Our company provides a complete series of blades suitable for your machine, which
you can buy from your retailer.

WarnInG! Before conducting any replacement, turn the switch to the OFF “O”
position and unplug the machine from the electric power supply.
WarnInG! after cutting the blade reaches high temperatures: Wait for it to cool
down before replacing it.
WarnInG! even if the blade has stopped, it is still very sharp: Use gloves to prevent
serious injuries.
WarnInG! the assembly of the blade must be carried out with absolute precision.
Incorrect assembly causes very serious danger.
When replacing the blade, proceed as follows. The operation must be carried out by
an expert; if in doubt please contact an authorised service centre.
1) Unplug the machine from the electric power supply and set the machine in cutting
off mode.
2) For correct reassembly, observe carefully the various components before proceeding.
3) Unscrew the screw ( Fig. M1) that secures the lever protections.
4) With 2 keys supplied, unscrew the screw securing the blade. Attention: the screw
has lefthand thread ; turn clockwise to unscrew it ( fig.M2 ).
5) Open the protections ( fig.M3 ), remove the outer flange and pull the blade down
(the inner flange must be mounted on the motor shaft). Be careful if there are rings
of adaptation or shimming.
8) Clean the components and the new blade.
9) Install the new blade being careful to follow the direction of rotation: the arrow of
the blade must be the same as that printed on the machine.
10) Replace the outer flange paying attention to the same shaped hole that will be stuck
on the contoured shaft of the motor.
11) Tighten the screw counterclockwise without hitting the key with hammer or other
tools ( fig. M2).
12) Replace the lever guards and secure it with the screw (Fig. M1).
13) Carefully check that all blade guards are operating properly.
14) Make sure that the blade spins freely without irregularities.
15 ) Carry out a test of unloaded run.
