3 INSTALLATION AND ASSEMBLY
3.1 LIFTING AND HANDLING
The machine arrives at its destination packed in a wooden crate, or wooden case or support.
Lifting and handling operations can be carried out using a fork lift truck or pallet jack.
Before beginning any manoeuvres, free the machine of all parts that have not been firmly fixed to it
due to transport or packaging requirements.
Check that the load bearing capacity of the lifting equipment used is suitable to the gross weight of
the machine (see data in the TECHNICAL SPECIFICATIONS).
For storage purposes, keep the machine in a dry place, away from rain, snow or humidity.
Use a fork lift truck or pallet truck for machine handling operations:
- if the machine is installed on a pallet, or inside a crate or case (4 M10 holes are available at the
base for anchoring the machine to a wooden pallet), insert the lifting forks on the fork lift truck (or
pallet truck) underneath the pallet until they protrude at the rear by at least 15 cm;
- lift slowly and handle with maximum care, avoiding oscillations to a minimum, and position the
machine in the pre-established work area.
-
Lifting and handlingoperations must be carried out by qualified,
speciallytrainedpersonnel.
- Makecertain the surrounding area is free of obstacles and that no oneis
in the immediate vicinity of the machine, or within the radius of the
equipmentbeingused for lifting, handling and/or transporting the
machine.
- Duringall lifting and handlingprocedures, use extremecaution to
avoidhazards to the machine people and property.

15
3.2 MACHINE PLACEMENT
The machine must be installed inside an industrial building that is well lit and ventilated, and has a
solid and level floor capable of supporting the machines weight, and not on a sloping floor.
The working environment should not be humid.
Set the machine in the most suitable position, according to production needs, positioning it in a
place where there is an easy connection to the mains line, and where there is sufficient lighting to
ensure that all parts of the machine are visible.
The lighting must comply with the laws in force in the country where the machine is installed, and
should provide good visibility at every point, without creating dangerous reflections, allowing a
clear view of the control panel and identification of the emergency buttons, without interfering with
any equipment installed on board the machine.
Make sure the machine is perfectly set on the floor.
Do not use solvents such as gasoline and diesel fuel when cleaning the machine, since these
substances can damage the paintwork and render it opaque, or produce rust on different parts.
3.3 INSTALLATION
- Remove the packing and check for any damage on the machine incurred during transport.
- Position the machine in a non-humid environment, on a stable non-sloping floor.
- Set a minimum clearance of 1 meter in order to allow for correct operation in safety conditions.
- Install the 4 anti-vibrating support feet supplied with the machine.
- Carefully clean the machine, removing grease from all non-painted parts.
- Lubricate the upper rocker arm guide support 3027 and greasers 3051.
- Assemble the machines lighting unit provided.
- Check to make sure the machines voltage corresponds to the power supply and connect to a
disconnecting switch.
- If the supply voltage does not match the machines voltage, change the connections on the motor
terminal block and transformer.
- Turn the main switch 3092 to the ON position.
- Press the pedal 361.
- Check the motors correct direction of rotation by making sure the grindstone 3282 turns in the
direction indicated by the arrow on the grinding wheel casing 113.
- If the direction of rotation is incorrect, invert two phase wires on the power cable.
- The machine is now ready for operation.

16
3.4 CONNECTING THE MACHINE TO THE POWER SUPPLY
The manufacturer recommends not connecting the machine to the power line until it has been
correctly set in its working location. Prior to connecting the machine to the power line, check to
make sure the electrical system meets the following power and safety requirements:
- Check to make sure the production plants grounding and trunk line to which the machine will be
connected are perfectly efficient.
- Make sure the trunk line to which the machine will be connected is protected upstream by a
differential switch.
- The mains must be provided with an efficient neutral and ground line (equipotential grounding).
- Ensure the presence of fuses or circuit breakers against short circuits on every RTD cable
conductor, except for the grounding.
- The electrical system must comply with CEI 64.8 (CENELEC HD 384, IEC364-4-41).
- Make sure the line voltage (V) and frequency (Hz) correspond to the machines design
specifications.
- If the voltage on the mains line is not identical with the machines voltage, change the
connections on the motor terminal and transformer.
Refer to the wiring diagrams annexed to this user manual for references.
After correctly connecting the machine to the mains line, start up the machine and check the
motors correct direction of rotation by making sure the grindstone 525 turns in the direction
indicated by the arrow on the grinding wheel casing 518.
If the direction of rotation is incorrect, invert two phase wires on the power cable (R-S-T or L1-L2-
L3); do not intervene on the Neutral and Ground connections when cutting off the voltage.
The machine is supplied with an electric cable without a plug; this allows the machine to be set to
the requirements of each country it is exported to.
WARNING: THE ELECTRICAL CONNECTION, OPERATING CHECKS AND
MAINTENANCE TO THE ELCTRICAL SYSTEM MUST BE PERFORMED BY
QUALIFIED AND TRAINED PERSONNEL ONLY
The manufacturerisnotliable for damage due to the machinesincorrect connection to the
mains line or problemsderiving from malfunctions to the mains line.

4 STARTING UP THE MACHINE
4.1 SETTINGS
To start up the machine:
- check to make sure the operating pressure is at 4 bar (check the gauge 516);
- turn the main switch 3092to the ON position;
- position an upper or shoe to be trimmed in the area of the punch tool
guide 624 and press the pedal 504 to half its stroke;
(the movable arm 559/569 will rise to the operating position).
- set the height of the movable arm 559 according to the thickness
of the material to be trimmed;
- proceed with the trimming operations, pressing the pedal 504 down completely and keeping the
upper set against the counter-punch tool 622.
Simultaneously with the machines start-up, the orange pilot light next to the main switch and the
lighting spots illuminating the machines cutting area will light up.
To stop the machine:
- turn the main switch 3092 to the OFF position.
The machine has a fixed cutting speed.

1. SAFETY DEVICES AND RESIDUAL RISKS
5.1 PREMISE
The machines risk analysis and related considerations, included in this section of the manual, are
based on the following notions:
- knowledge of normal operating conditions and the machines expected usage, as specified in this
user manual.
- the premise that the machine is designed to be used for trimming linings on holes and eyelets on
uppers and/or lasted footwear.
- the premise that machine operators have been suitably trained and made aware of specific risks.

20
Protective measures provided by the production manager to workers are: collective and individual.
5.2 INFORMATION ON RESIDUAL RISKS
In spite of the validity of the protection systems adopted by the manufacturer, the machine operator
is nonetheless exposed to the following hazards:
Contact with the machines operating tool.
Contact with moving parts (drive belts, cutting tools, gears, etc.).
Ejected inserts from the tool.
Electrocution due to contact with live parts.
Hazard related to an incorrect tool assembly.
5.3 PERSONAL PROTECTIVE EQUIPMENT
The manufacturer recommends the use of the following personal protective equipment to prevent
risks during installation, adjustments, operation, routine and extraordinary maintenance:
gloves (e.g. in handling machine parts and replacing the cutting tools);
protective non-slip safety footwear;
eye goggles or a face shield against possible splinters during processing or subsequent machine
cleaning;
dust masks.
! The use of eye goggles or a visor is mandatory during the
sharpening of the punch tool 621 and counter-punch tool 622 on the
grindstone 525.
Nevertouchanymoving part on the machine duringitsoperation, for
anyreason, whetherdirectly or indirectly.
Always makesurethat the machine isdisconnected from
allelectricalpowersourcesbeforecarrying out anycleaning, lubrication,
maintenance, repairs, adjustments or part replacements.
The operator mustntever, for whateverreason, leave the machine
unattendedwhen in use.
