“The quoted values for noise are emission levels and not necessarily safe working
levels. While there is a correlation between emission levels and exposure levels, this
cannot be reliably used to determine whether or not additional precautions are
required. Factors affecting the actual exposure level of the worker include the
duration of exposure, the characteristics of the environment, other emission sources,
e.g. the number of machines and other adjacent processes. Permitted exposure
levels may also vary from country to country. However, this information enable the
user of the machine to make a better assessment of the dangers and risks ".

3- GENERAL SAFETY RULES
3.1 PREMISE
Although the rigid and massive assembly offers the maximum guarantee for solidity
and robustness, a good placement is always advisable to increase the solidity and
eliminate unnecessary and harmful vibrations. The manufacturer is exempt from
any responsibility for any damage caused by negligence.
SAFETY RULES
1) Before connecting to the electrical network, it is necessary to check that there is
adequate protection upstream of the line, with differential magnetothermic
protection and equipped with an earth conductor.
2) Check that the voltage and frequency indicated on the plate correspond to those
of the net.
3) Do not use cables, extensions, or plugs that are defective or not compliant with the
regulations.
4) Make sure that work is always carried out in safe conditions.
5) Always start work with the machine in a stable position.
7) Do not use or expose the tool to rain.
8) Position the cable correctly when working, that it always remains away from
the work area and that it is long enough to allow you to work.
9) Remove always current from the net connection during maintenance.
10) Use of the machine is allowed to adults and competent people.
11) During work, scrupulously follow the instructions on the machine.
12) The machines from our production are built with the required technical and
safety measures. Customers are therefore advised to strictly follow the rules
described in this booklet.

safety footwear and work gloves, do not work with loose clothing.
3.2 POSITIONING THE MACHINE (fig. 1)
A space of at least 1.5 meters must be left around the machine for the passage of
people and things, without creating the risk of collisions and allowing normal
maintenance operations.
A DANGEROUS AREA is to be considered any area inside and / or near a machine
in which the presence of an exposed person constitutes a risk for the safety and
health of that person.
Any person who is wholly or partially in a dangerous area is to be considered an
EXPOSED PERSON.

4 - HANDLING AND INSTALLATION
4.1 TRANSPORTATION BY TRUCK
Due to its particularly sturdy monolithic structure, the machine can be easily
transported without any disassembly operations; however, it is important to pay
attention to the following rules:
–make sure that the lifting ropes are correctly hooked to the four lifting eyes;
–We recommend avoiding shocks or sudden shocks both in the lifting phase and in
the support phase of the structure;
–in the case of long journeys with routes that are not necessarily straight, it is very
important to tie the structure well to the means of transport, because the center of
gravity is very high and accidents can occur due to speed both when cornering and
on bumps or slopes;
–all machines are equipped with special lifting hooks, so please use them in order
to avoid inconveniences.
4.2 LOADING UNLOADING AND HANDLING
The machine must be transported leaving it resting on the feet on a level surface.
The movement is carried out by lifting it from the crossbeams of the bench, then
placing it gently on the ground, without knocks.
Or by lifting it by means of a harness with special textile straps for lifting (Fig. 2)
Fig. 2
IMPORTANT: Lift the machine by hooking it to all four lifting
eyes, so that the load is balanced.

VERS. 2022.10.14 CWT 315_MAN_EN
18
4.3 PRELIMINARY CHECKS
To move, repair, maintain or inspect, make sure
the machine is unplugged from the power socket.
Before inserting the power plug you need to:
- Place the machine on a stable and level
surface to ensure optimal support.
- Check that the state sharpness of the cutting
disc is in good condition conditions.
- The blade must be free of cracks or cracks
have all teeth at the same length; to be perfectly close and
connected.
- Check that the tightening of the nut that fixes the cutting
blade between the two flanges is sufficient to guarantee
the blocking of the blade itself.
- The belts are tensioned by releasing the motor screw (Fig.
3), and turning the motor clockwise (Fig. 4). While holding
the straps under tension, re-lock the screw.
- Make sure that the power socket has the same phase
characteristics as the electric motor, and that the power
supply line is equipped with a differential switch and
magneto-thermal protection (or with a fuse for short circuit
max 15 Amp).
- After these preliminary operations, the electrical
connection can be made.
LIGHTING
The saws are not equipped with lighting and therefore must
be used in adequately lit outdoor environments.
If it is not possible to have perfect visibility of the cutting line,
the use of the saw should not be authorized.

5 - STARTING AND STOPPING
5.1 STARTING AND STOPPING THE MACHINE
The switch is placed in a convenient position and accessible from the operator's
workplace. It is of the motor protection type with thermal protection, against current
surges and with release coil in the absence of voltage.
For starting
(only after having carried out all the preliminary
operations), press the green button (1 Fig. 5).
For normal shutdown
press the red button (2 Fig. 5).
For Emergency stop
press the red button (2 Fig. 5).
The stopping time from the blade is less than 10 seconds, therefore Directive
2006/42 / EC does not provide for an additional emergency device as it does not
allow to reduce the risk.

5.2 INSTRUCTIONS FOR USING THE ELECTRICAL EQUIPMENT
Please observe the following warnings:
Do not operate the appliance if the power cable, motor cable or switch show
visible damage.
Turn off the switch before carrying out any maintenance, adjustment or repair
work and unplug the power cord from the socket. Wait until the blade has
completely stopped.
GICs equipped with an electronic brake maintain voltage on the motor even
after it has been switched off.
- Check it out the power cord before connecting. Incorrect connections can
cause the destruction of the electrical system.
- Observe the mains voltage. The data indicated on the motor identification
plate must correspond to the data of the electrical network.
- Only connect electronic equipment to a power cord with sufficient overload
protection.
In the event of a prolonged break from work without the operator being absent
or if the machine is switched off, the plug of the power supply cable must be
removed from the socket (main switch function).
- Connecting the GIC to the motor can only be done by a qualified specialist.
In the event of a power failure, the electric brake does not work. Therefore, the
machine cannot be put into operation without an operator. Do not insert your
hands into the danger zone.
Avoid short switching cycles. The high thermal stress that occurs in the event of
frequent starting and braking operations can damage the motor. The switch and
the
electronic brake.
For the mod. single phase:
- Please note that use is not continuous, therefore the machine must be used
in alternating times: 10 minutes of work and 15 minutes of pause.
Operation with a generator is not recommended in principle. Strong voltage
fluctuations and spikes are a particular danger to switches that contain
electronic components.
We decline all responsibility for damage caused by failure to comply with
what specified above.
Explanation of terms:
GIC = plug switch assembly
= failure to comply with the warning can cause damage to people
and the machine as well as material damage.
