Usage
WARNING!
Improper use of the circular metal saw
• will endanger personnel,
• will endanger the machine and other material property of the operator,
• may affect proper operation of the machine.
The circular metal saw is designed and manufactured to be used in environments where there is
no potential danger of explosion.
The circular metal saw is designed and manufactured to saw cold metals, cast materials and
other plastic materials that are not harmful to health and do not generate dust.
The circular metal saw must not be used on wood.
The pieces to be cut need to be of a shape that will allow them to be securely attached in the
work holder vice and ensure that the piece does not come loose when it is being sawed.
The circular metal saw must only be installed and operated in a dry and well-ventilated place.
Improper
use
If the circular metal saw is used in any way other than as described above, modified without the
authorisation of supplier or operated with different process data, then it is
being used improperly.
We do not take liability for damage caused by improper use.
We would like to stress that any modifications to the construction, or technical or technological
modifications that have not been authorised by supplier will also render the
guarantee null and void.
It is also part of proper use that
• the maximum values of the circular metal saw are complied with,
• the operating manual is observed,
• inspection and maintenance instructions are observed.
“Technical data“ on page 14
In order to achieve the required cutting performance and the angular tolerance the correct
choice of the saw blade, the cutting speed and the coolant are decisive.
WARNING!
Very serious injury.
It is forbidden to make any modifications or alterations to the operating values of the cir-
cular metal saw! These could endanger personnel and cause damage to the machine.
1.3 Possible dangers caused by the circular metal saw
The circular metal saw is state-of-the-art, but there is a residual risk, as the circular metal saw is
