1.1 Safety warnings (warning notes)
1.1.1 Classification of hazards
We classify the safety warnings into various levels. The table below gives an overview of the
classification of symbols (pictograms) and warnings for the specific danger and its (possible)
consequences.
Pictogram Alarm expres-
sion Definition/Consequences
DANGER! Imminent danger that will cause serious injury or death to
personnel.
WARNING! Risk: A danger that might cause serious injury or death to
personnel.
CAUTION! Danger or unsafe procedure that might cause injury to
personnel or damage to property.
ATTENTION!
Situation that could cause damage to the machine and
product and other types of damage.
No risk of injury to personnel.
INFORMATION
Application tips and other important or useful information
and notes.
No dangerous or harmful consequences for personnel or
objects.
In the case of specific dangers, we replace the pictogram by
or
general danger with a warning
of injuries to hands, hazardous elec- trical voltage, rotating parts.

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.
Caution
slide risk! Activation forbid-
den! Pull the mains plug! Use protective goggles! Use ear protec- tion!
Use protective
gloves! Use protective boots! Wear a safety suit! Protect the envi- ronment! Contact address

Safety
Page 7
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 Colovos Company 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 Colovos Company 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 16
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
working with
• electrical voltage and currents
• a running circular metal saw blade.
We have used construction resources and safety techniques to minimise the health risk to per-
sonnel resulting from these hazards.
If the circular metal saw is used and maintained by staff who are not duly qualified, there may be
a risk resulting from incorrect operation or unsuitable maintenance.
INFORMATION
All staff involved in assembly, commissioning, operation and maintenance must
• be duly qualified,
• follow this operating manual.
In the event of improper use
• there may be a risk to the staff,
• there may be a risk to the circular metal saw and other material property,
• the proper operation of the circular metal saw may be affected.
Disconnect the circular metal saw whenever cleaning or maintenance work is being carried out.

Safety

WARNING!
THE CIRCULAR METAL SAW MAY ONLY BE USED WITH THE SAFETY DEVICES ACTI-
VATED.
Disconnect the circular metal saw whenever you detect a failure in the safety devices or
when they are not fitted!
All additional installations carried out by the operator must incorporate the prescribed
safety devices.
Being the machine operator, this will be your responsibility!
 “Safety devices“ on page 9
1.4 Qualification of personnel
1.4.1 Target group
This manual is addressed to
• users,
• operators,
• maintenance staff.
The warning notes therefore refer to both operation and maintenance of the circular metal saw.
Determine clearly and irrevocably who will responsible for the different activities on the machine
(use, maintenance and repair).
Vague or unclear assignment of responsibilities constitute a safety hazard!
Always disconnect the circular metal saw from the power supply and secure the circular metal
saw against restarting.
1.4.2 Authorised personnel
WARNING!
Incorrect use and maintenance of the circular metal saw constitutes a danger for the
staff, objects and the environment.
Only authorised personnel may operate the circular metal saw!
The only staff authorised to use this machine and perform maintenance on it are trained and
instructed technical staff working for the operator and manufacturer.
The operator must
Obligations
of the opera-
tor
• train staff,
• instruct staff regularly (at least once a year) on
- all safety standards that apply to the machine,
- operation,
- accredited technical guidelines,
• check staff‘s understand,
• document training/instruction,
• require staff to confirm participation in training/instruction by a signature,
• check whether the staff are aware of safety and of dangers in the workplace and whether
they observe the operating manual.

Safety
Page 9
The user must
Obligations
of the user • have received training in operation of the circular metal saw,
• know the function and principle of operation,
• before the machine is first used
- have read and understood the operating manual,
- be familiar with all safety devices and regulations.
Additional
qualification
require-
ments
For work on the following machine components there are additional requirements:
• Electrical components or devices: This work must only be carried out by a qualified electri-
cian or person working under the instructions and supervision of a qualified electrician.
Before carrying out work on electric components or operating units the following measures
must be taken, in the order given.
- Disconnect all poles
- Ensure that the machine cannot be turned on again
- Check that there is no voltage
1.5 User positions
The user must stand in front of the circular metal saw.
INFORMATION
The mains plug of the circular metal saw must be freely accessible.
1.6 Safety measures during operation
CAUTION!
Risk due to inhaling of health hazardous dusts and mist.
Dependent on the material which need to be processed and the used auxiliaries dusts
and mist may be caused which might impair you health.
Make sure that the generated health hazardous dusts and mist are safely sucked off at
the point of origin and is dissipated or filtered from the working area. Use an appropriate
suction unit.
CAUTION!
Risk of fire and explosion by using flammable materials or cooling lubricants.
Take additional preventive measures in order to safely avoid health hazards before
processing flammable materials (e.g. aluminum, magnesium) or before using flammable
additives (e.g. spirit).
1.7 Safety devices
Use the circular metal saw only with properly functioning safety devices.
Stop the circular metal saw immediately if there is a failure in the safety device or if it is not func-
tioning for any reason.
It is your responsibility!
