Introduction

This operation instruction manual conforms to the requirements of European Standard
2006/42/EC Machine Directives and subsequent amendments.
In the light of this，special attention has been given to safety aspects and accident
prevention in the work-place for each stage in the machine’s “life”. Information which
could be of particular assistance to the operator has been high lighted.

The “Operating instructions” are an integral part of the machine and should be

consulted before, during and after the start up of machine and whenever else required.
The content of these instructions should always be carefully observed.
The observance of the above is the only way to achieve the two fundamental aims of
this manual:

● Optimization of machine performance

● Prevent damage to the machine and injury to the operator

CAUTION: BEFORE INSTALLING THE MACHINE, READ THE OPERATING
INSTRUCIONS CAREFULLY

1. Accident prevention and safety instruction

This machine has been designed to comply with national and community
accident-prevention regulations, improper use and / or tampering with the safety
devices will relieve the manufacturer of all responsibility.

1.1 Advice for the operator

A. Check that the voltage indicated on the machine motor is the same as the line

voltage.

B. Check the efficiency of your electric supply and grounding system; connect the

power cable of machine to the socket and the ground lead (yellow-green) to the

grounding system.
C. When the saw frame is in suspended mode (or raised), the blade must not move.
D. Only the blade section used for cutting must be kept unprotected. To remove

guards operate on the adjustable head.
E. It is forbidden to use the machine without its shields.
F. Always disconnect the machine from the power socket before blade change or

carrying out any maintenance job, even in the case of abnormal machine operation.
G. Always wear suitable eye protection.
H. Never put your hands or arms into the cutting area while the machine is operating.
I. Do not shift the machine while it is cutting.
J. Do not wear loose clothing like: shirts with sleeves that are too long, gloves that are

too big, bracelets, chains or any other objects that could get caught in the machine

during operation. Tie back long hair.
K. Keep the area free of equipment, tools, or any other objects.
L. Perform only one operation at a time. Never have several objects in your hands at

the same time.
M. Keep your hands as clean as possible.
N. All internal operations, maintenance or repairs, must be performed in a well-lit area

or where is sufficient light from extra sources so as to avoid the risk of even slight

accidents.

1.2 The electric equipments according to European Standard “2006/42/EC”
which some integrating modifications.

A. The electric equipment ensures protection against electric shock as a result of

direct contact.
B. The active parts of this equipment are housed in a box to which access is limited by

screws that can only be removed with special tools; the parts are fed with

4

alternating current as low voltage (24V). The equipment is protected against

splashes of water and dust.
C. Protection of the system against short circuits is ensured by means of rapid fuses

and grounding; in the event of a motor overload, protection is provided by a thermal

probe.
D. In the event of a power cut, the specific start-up button must be reset.
E. The machine has been tested in conformity with European Standard.

1.3 Emergencies according to European Standard “2006/42/EC”.

In the event of incorrect operation of danger conditions, the machine may be stopped
immediately by pressing the red emergency button.
The casual or voluntary removal of the blade cover of the flywheels causes the
stepping-in of a interlock switch that automatically stops all machine functions.

Note: resetting of machine operation after each emergency stop require specific

restart button.

2. Description of machine

2.1 Description of machine and its components

The band sawing machine produced by us has a sturdy frame made from welded and
painted sheet-steel. The upper surface is designed to allow the complete draining
away of the cutting fluid. The band holding bow is made of cast-iron and has generous
dimensions，providing the cutting unit with the necessary strength and precision. The
vice unit is made of cast-iron and clamps the material to be cut securely. The bar-stop
device allows the length required to be preset and a constant level of performance for
repeated cuts. The blade-holding bow is firmly attached to a reduction unit built onto
the motor and to the base by means of a joint which allows 60° and 45° rotation to the
right and left. This joint also allows the cutting movement to advance manually or by
falling.
The coolant pump is fitted to the machine base. The main switch is located on the
front panel. The choice of one of the two motor rotation speeds and therefore cutting
speed is carried out by the main switch. The front panel is also fitted with an
emergency stop button and a START button. The control lever，fitted with an
ergonomic hand-grip and activation button with safety release action, reduces fatigue
during operation to a minimum. The blade is protected by a guard with interlock which
covers the upper area and the hand wheels and by two adjustable lower guards which
protect the operator from ejected shavings and coolant. The machine is supplied with

5

a set of service spanners.

2.2 Intended and unsuitable uses of machine

The band sawing machine has been designed and built to cut bars, structural steel
and ferrous metal pipes in accordance with the instructions contained in this manual.
Therefore, the cutting of other materials is not permitted: if the above
recommendations are not observed，the machine could be damaged and the health
and safety of the operator put at risk. Cutting is not permitted, if the bar has not been
first locked in the vice.

3. Main technical date

4. Handling and transportation

For safe handling and transportation use a lift truck for movement indoors. Keep the
machine in its normal position and avoid turning it upside down. If the machine is
fastened to the pedestal, stability will be greatly reduced and therefore all the
necessary measures should be taken to stop the machine from tipping over.
