Functional parts
PH211 model
In order for the user to move towards a full understanding of how the machine
works, which is described in detail in the chapter 5, this chapter deals with the
main units and their locations.
Cutting head
The cutting head is the unit that cuts the material. It consists of a cast iron head
on which the following are mounted: the band saw, the blade guide components,
the blade tensioner components, the transmission box and the spindle motor. The
cutting head is limited in its movements by the joint on the work table, and its
cutting stroke is manually guided by the operator.

Use and maintenance manual PH211
Vice
The vice is the unit that clamps the workpiece in place during cutting; it consists
ofavicesupport,commonlyknownasaleadnut,fixedtotheworktable,anda
lead screw with a slideway on which the mobile jaw is mounted. The vice is
operated manually by a handwheel, or by a pneumatic cylinder in the MA version
(optional).
Control Panel
The control panel has a protection rating of IP 54 and contains the electrical
equipment. Access is gained by removing the screws fastening a safety panel,
while the operator’s safety is guaranteed by a key---operated safety switch,
designed to prevent any intentional interference with the unit. In order to remove
the panel from its mounting, the main switch has to be shifted to 0 (OFF), which
automatically cuts off the electrical supply.

Use and maintenance manual PH211
The o perator must not perform any risky operations or operations not
required for the machining operation under way (e.g. remove swarf or
metal shavings from the machine while cutting).
Remove equipment, tools or any other objects from the cutting zone; always keep the working area as clean as possible.
Before starting any cutting operations, ensure that the workpiece is securely held in the vice and the machine has been set correctly. A number of
examples of how to clamp different profiles correctly in our machines are
shown below.
Do not use the machine to cut pieces that exceed the capacity of the machine as listed in the machine specifications.
Never move the machine while it is cutting.
Do not use blades of different sizes to those recommended in the machine specifications.
When cutting very short pieces, make sure that they are not dragged behind the support shoulder, where they could jam in the blade.
When working on the band saw, wear gloves only when handling materials and for tool changing or adjustment operations. Only perform one
operation at a time and do not hold more than one item or operate more
than one device simultaneously. Keep hands as clean as possible.
Warning: if the blade jams in the cut, press the emergency stop push--button immediately. If this does not free the blade, slowly loosen the
vice, remove the piece and check the blade or blade teeth for breakage.
Replace the blade if necessary.
Before carrying out any repair work on the machine, consult the Technical Assistance Service: this can be done through a re presentative in the
country of use of the machine.

Safety and accident prevention
Emergency devices
In accordance with Standard CEI 204 ---1:
H Chapter 5 Section 6 Sub--section 1 “Emergency stop device”: «the emergency
stop device immediately stops all the dangerous and other functions of the machine»;
H Chapter 6 Section 2 Sub--section 4 Point 7 “Protective guards”: «the removal
of protective guards designed to prevent access to dangerous parts or zones causes
the machine to stop immediately; replacing the guards does not restart the functions, which must be reset».
...Emergency devices applicable to the PH211:
1. Emergency stop: a non---return mushroom---head pushbutton, colour red on
yellow background, is located on the control panel of the machine. To release
the pushbutton, the actuator must be rotated 45˚. After the emergency situation has been resolved, the machine must be reset.
2. Automatic thermal---magnetic cutout switch with thermal--- magnetic relay:
the machine auto switch, located on the control panel, has two protection systems against voltage drops. In the case of a voltage drop, all electrical components are disengaged, the machine stops immediately, and automatic restart
when the power supply returns is inhibited. Another function is that of resetting the thermal relay provided to protect against overcurrents.
3. Pressure contact for monitoring blade tension: the machine stops immediately if the blade breaks or if the tensioner cylinder pressure drops.
4. Protective guard for blade: a coded key microswitch is operated if the blade
cover is accidentally or intentionally opened during the machine operating
cycle, immediately shutting down all functions.

Noise level of the machine
Noise can cause hearing damage and represents one the problems faced by many
countries who adopt their own standards. In accordance with the EEC MA-
CHINES DIRECTIVE 98/37/CE , we are listing the standards that specify noise
levels for machine tools. This chapter also reports the noise levels produced by
the PH211 during its various operating phases and the methods used for measuring these levels. The Italian standard governing this aspect is D.M.n.277/91 drawn
from EEC Directives 80/1107, 82/605, 83/477, 86/188, 88/642, UNI EN ISO 4871
(1998).
Noise level measurement
Noise levels are measured using an i nstrument known as an Integrator noise--meter which registers the equivalent continuous acoustic pressure level at the
work station.The damage caused by noise depends on three parameters: level,
frequency and duration. The equivalent level concept Leq combines the three
parameters and supplies just one indication. The Leq is based on the principle of
equal energy, and represents the continuous stationary level containing the same
amount of energy, expressed in dBA, as that actually fluctuating over the same
period of time.This calculation is made automatically by the integrator noise --meter. The measurements are taken every 60 seconds, in order to obtain a
stabilised value. The reading stays on the display for a sufficient time to enable a
reading to be taken by the operator.Measurements are taken by holding the
instrument at approximately 1 metre from the machine at a height of 1.60 metres
above the platform at the operator’s work station.
Two measurements are taken: the first while the machine operates without cutting
anything, the second while cutting in manual mode.

Electromagnetic compatibility
As from 1 January 1996 all electrical and electronic appliances bearing the CE
marking that are sold on the European market must conform to Directive
89/336/EEC and 70/23/CEE and 98/37/CEE. The prescriptions regard two specific
aspects in particular:
1. “EMISSIONS: during its operation, the appliance or system must not emit spurious
electromagnetic signals of such magnitude as to contaminate the surrounding
electromagnetic environment beyond clearly prescribed limits”;
2. “IMMUNITY: the appliance or system must be able to operate correctly even when
it is placed in an electromagnetic environment that is contaminated by disturbances
of defined magnitude”.

The base of the machine is anchored to the floor by two permanent studs located
on the sides of the base. The studs are screwed into nuts previously sunk into the
concrete, and tightened from above with lock nuts. The schematic specifications
set out in Chapter 1 should be taken into account when positioning the machine.

Balancing the cutting head
Before making the electrical connections, the head return springs must be
tensioned to balance the cutting head weight. Using a 10 mm. wrench, tighten the
screws until the distance between the first coil of the spring and the bracket is 8
mm.
Connection to the power supply
Before connecting the machine to the power supply, check that the socket is not
connected in series with other machines. This requirement is fundamental for the
good operation of the machine.
To connect the machine to the power supply, proceed as follows:
" connect the power supply cable of the machine to a plug which matches the
socket to be used. (EN 60204 ---1; par. 5.3.2)

When using systems with a neutral wire, special care must be taken when connecting the blue neutral wire, in that if it is connected to a phase wire it will discharge the phase voltage to the equipment connected for voltage: phase--
neutral.

" Power up machine by rotating the main switch located on the right side of the
control panel (The STAND BY LED lights up).
Check that the motor is rotating in the correct direction. For this check the
following operations must be carried out:
" set the blade tension to 70 BAR;
" make sure the cover is properly closed: at the back of the cutting head there is
a bayonet limiter for correct cover closure;
" make sure that the machine is not in an emergency condition (red mush-
room ---head pushbutton released);
" select a cutting speed using the polarity change switch;

" operate the jog button on the manual head control lever;
" if all the above operations have been carried out correctly, the blade motor
will start up and the blade will start rotating.
Ensure that the blade moves in the correct direction as shown in the above figure. If it does not, simply reverse two of the phase wires on the machine
power supply input.
The sawing machine is now ready to start the work for which it was designed.
Chapter 5 provides a detailed description of the various functions of the machine
and its operating cycles.
