1.1 MACHINE DESCRIPTION
Vertical single shaft milling machine, for machining wooden pieces by chip removal with
rotary tool installed on the shaft.
The machine has manual feeding, with a single vertical shaft, which can be fixed or in-
terchangeable, with fixed position during the machining and a horizontal supporting
plane, fixed during the machining. The shaft passes through the plane, and the driving
motor is positioned below. The machine can have one or more of the following configur-
ations:
•the possibility of choosing up to 5 rotation speeds for the tools depending on
their diameter and type of machining to be made;
•the possibility of adjusting the shaft in vertical position through the plane;
•the possibility of increasing the supporting surface by adding additional planes;
•motor direct starting by push button;
•the reversal of the shaft rotation direction;
•possibility of installing the interchangeable spindle.
1.2 CONFORMITY
The machine has been planned and built according to the norms ANSI 01.1: April 1991

2 WORKING SAFETY
2.1 GENERAL SAFETY RULES
The machine operator and the person in charge must read this instruction handbook
carefully and completely before executing any operation on the machine.
Keep this handbook close to the machine.
The manufacturer is continuously improving the products, so some machine compo-
nents may possibly change.
All the technical information in this handbook are exclusive property of the manufac-
turer and are strictly confidential.
Thus, it is forbidden to reproduce and disclose them, even partially, without a written
authorization by the manufacturer.
It is also forbidden to use this handbook for purposes other than those strictly con-
nected with the installation, use and maintenance.
For detailing shortly and clearly the operation, adjustments and other, some figures
may show the machine without safety guards. DO NOT USE the system under these
conditions, and in case of maintenance or repair interventions follow the indications in
the chapter: MAINTENANCE.
2.1.1 Operator training
It is extremely important that all the operators are suitably trained in the use, adjustment
and utilization of the machine.
Above all:
a) the principles for adjusting and using the machine, including a correct use and ad-
justment of the devices for guiding and holding the piece, guards and tools.
b) The tool correct selection for each operation.
c) The position of the hands with respect to the tool.
2

T120C
8
d) The safe piece handling while machining, following the recommendations for
using templates and similar devices:
•to use roller devices or extension tables when long pieces are machined.
e) The safe storage of pieces before and after the machining.
f) The correct adjustment of the safety devices.
g) To start the machining only when the tools have reached the operating speed.
h) The use of personal protections for the ears, eyes and lower limbs.
This machine has been designed and manufactured to give the user a suitable safety
but, like all machines provided with cutting systems, it may cause dangerous situations
due to incorrect use of the machine, lack of experience or tampering with the safety
devices of the machine; therefore the operators should take these remarks into ac-
count and carefully follow the instructions given in this handbook about safety.
2.1.2 Safety plates
On the machine (Fig. 3) some safety plates, Table 1 have been installed to warn the
operator about the residual risks on the machine, the suitable use of the working equip-
ment and the safety measures that must be followed during the maintenance interven-
tions.

2.1.3 Symbols
To point out the handbook sections concerning personal safety, the following symbols
have been used in the USE AND MAINTENANCE operations of the machine:
ATTENTION
Information or procedure that, if not carefully followed, could cause death or serious
personal injuries.
CAUTION
Information or procedure that, if not carefully followed, could cause light personal in-
juries or machine damages.
ELECTRIC DANGER
Information or procedure that, if not carefully followed, could cause death or serious
personal injuries.
WARNING
Information or procedure that aids the operator in the best use of the machine
or equipment, to lengthen their life, avoid damages or programming losses, op-
timize the work in compliance with safety norms.

T120C
11
NOTE
Important information or procedure
It is recommended to use the personal protection devices for the eyes.
It is recommended to use the personal protection devices for the ears.
It is recommended to use the personal protection devices for the hands.
It is recommended to use the personal protection devices for the lower limbs against
the squeezing due to falling pieces during the operation.
2.2 MACHINE CORRECT AND IMPROPER USE
The machine can carry out milling operations (profiling and tenoning) on deadwood,
veneered wood, plastic materials with features similar to wood.
Any other use or machining on a material other than the indicated ones (for example
metals or materials with similar features) is forbidden, as it can be risky for the operator.
The manufacturer will not be responsible for damages or injuries to people and/or
things caused by a use non-complying with the norms. The risk will exclusively be at
the user’s charge.
This machine cannot operate in explosive environments.
2.2.1 Number and position of the working places
For a correct and safe use of the machine a single operator is expected, whose working
place is located in front of the guard for the guide machining.

T120C
12
Fig. 4: Working place
2.3 INDIVIDUAL RISK FACTORS
Some clothes or accessories worn by the operator can cause accidents. It is advisable
to avoid wearing dangerous objects, such as: rings, watches, bracelets, large-sleeved
overalls, not perfectly fastened belts, ties and, generally, anything sticking out of the
person that may be grasped by a moving part of the machine during its operation:
people with long hair should keep it gathered on the back of the neck, and possibly wear
a cap.
People not belonging to the work place shall absolutely stay far off the operating ma-
chine.
2.4 ENVIRONMENTAL RISK FACTORS
The place of work must be properly illuminated.
The operations performed by the machine produce dust and, in general, the machine
is in a place where other machines spread dust in the environment; to avoid dangerous
dust concentrations it is necessary:
•to make a correct connection with the suction system;
•to periodically carry out the maintenance on the suction system filters;
•further, as the dust deposited on the floor generates danger conditions, it is
necessary to carefully clean the place of work close to the machine periodically.
2.5 RISK FACTORS CONNECTED WITH THE MACHINE USE
•When the machine is connected to the mains, check the correspondence be-
tween the electrical features of the machine and those of the mains; it is also

T120C
13
advisable to check the correct grounding of the machine; these steps must be
recalled to the specialized technician carrying out the electrical connection.
•Before carrying out any maintenance on the machine, switch and cut it off from
power sources, set the main switch on zero and lock it.
•Machining pieces that are too small or too big for the machine capacity may
cause a dangerous situation for the operator or the people near the machine;
always compare the sizes of the pieces being machined with the max. and min.
dimensions that the machine can work.
•Do not remove or change the protection devices to change the operating ca-
pacity of the machine.
•Be very careful when choosing and maintaining the tools.
•Never use cracked, strained or excessively worn tools, as their utilization im-
pairs the machining quality and can involve risks for the people nearby the ma-
chine, as well as further increase the machine noise.
•Always wear gloves when handling the tools; refer to the data in the handbook
for the knife locking and projecting, as well as for the best adjustment of the
knife locking screws.
•A correct maintenance will ensure higher working safety as well as a constant
quality level of the machining.
•The protection devices must be regularly checked for their operation, for
example before every working shift.
2.6 PROTECTION AND SAFETY DEVICES
The machine is equipped with the following protection and safety devices:
