CHAPTER 2 - Safety and Accident Prevention
The Brobo Group S315/S350/S400 Series Metal Cutting Saw has been designed and manufactured in
accordance to Australian Standards. It is HIGHLY RECOMMENDED that the instructions and warnings contained
in this chapter be carefully followed for correct usage of the machine.
2.1. Operation of the Machine
The BW S315/S350/S400 Series Metal Cutting Saw is specifically design to cut ferrous and non-ferrous metal
cross sections with solid or thin-walled profiles. Other types of material and machining are not compatible for use
with the specifications of the saw. This machine involves a high-speed blade rotation; therefore extreme
caution is required when operating the device.
The employer is responsible for instructing the personnel who, in turn, are obliged to inform the operator of any
accident risks, safety devices, noise emission and accident prevention regulations provided for by national and
international laws governing the use of the machine. The operator must be fully aware of the position and
functions of all the machine’s controls.
All those concerned must strictly adhere to ALL instructions, warnings and accident prevention standards
in this manual.
The following definitions are those provided for by the EEC DIRECTIVE ON MACHINERY No. 98/37/CE:
 Danger Zone - any zone in and/or around a machine in which the presence of a person constitutes a
risk for the safety and health of that person.
 Person Exposed - any person finding him or herself, either completely or partly in a danger zone.
 Operator - the person or persons given the responsibility of installing, operating, adjusting, maintaining,
cleaning, repairing, and transporting the machine.
2.1.1. Noise Level
The noise level of an idling metal saw, fitted with a 180-tooth blade (supplied as standard by Brobo Group) has
been measured to be below 85 dBA. This complies with the Australian Occupational Health and Safety (Noise)
Regulations 1992.
Please note that peak impulse noise levels will be experienced due to variables including blade characteristics, type,
and condition. This will also vary accordingly depending on the size and type of sample being cut. Under these
circumstances, management should make available to the operator(s) the appropriate hearing protection equipment
as prescribed under the above stated act.
WARNING – UNAUTHORISED MODIFICATIONS/REPLACEMENTS/USE
The manufacturer declines any responsibility whatsoever, either civil of criminal, in the case of
unauthorised interference or replacement of one or more parts or assemblies on the machine, or if
accessories, tools and consumable materials used are different from those recommended by the
manufacturer, or if the machine is inserted in a plant system and its proper function is altered.
!
Page 12
Instruction Manual for VS315D (S040)
04/04/2019

Brobo Group
2.1.2. Power Supply
The 415/240V power supply requirements for this machine are of a high level and unauthorised interference and or
inadequate maintenance could result in a situation that could put the operator at risk. A qualified electrical engineer
should always be assigned to maintain and repair the system.
2.1.3. Compressed Air Supply
Various functions of the saw are carried out via the use of 6kPa compressed air. During these operations, situations
would arise where machine parts and materials are clamped together and would potentially pose a serious safety
issue to an inexperienced operator. Operators should be thoroughly instructed about these hazards.
Only a qualified electrician should carry out regular maintenance of this system.
2.2. General Requirements
Lighting
Insufficient lighting during the operation of the saw unit would constitute a safety hazard for the people concerned.
For this reason, the user of the machine must provide adequate lighting in the working area to eliminate areas in
shadow, whilst also preventing dazzling illumination sources
(Reference standard ISO 8995 - 2002 ‘Lighting of Indoor Workplaces’).
Connection
Check that the power supply cables, compressed air supply (if applicable) and coolant system complies with, and
are operating within the acceptable range of the saw capabilities.
Faulty, damaged or worn components must be replaced immediately.
Earthing Systems
The installation of the earthing system must comply with the requirements stated in the:
IEC Standards Part 195: Earthing and Protection Against Electric Shocks 1998.
Position of the Operator
The user controlling the machine saw operations must be positioned as shown in the figure 5 below.
Figure 5. Correct Position for Operating Saw Unit
Page 13
Instruction Manual for VS315D (S040)
04/04/2019

Brobo Group
2.3. Advice for the Operator
Protective eyewear or goggles must be worn at all times while attending and operating the
metal saw.
Do not attempt to operate the machine unless all safety guards are in operation.
The guard must fully cover the blade when the head is in the uppermost position.
Ensure that hands and arms are kept clear of the cutting zone when the machine is operating.
Do not wear loose clothing with long sleeves and oversize gloves, bracelets, necklaces or any
other loose object that may become entangled in the machine’s blade during cutting. Long hair
must be tied back or placed in a hair net.
Always disconnect the power supply to the machine before carrying out any maintenance
work or adjustments. This includes cases of abnormal operations of the machine.
Any maintenance work performed on the hydraulic, pneumatic or coolant systems must be carried
out only after the pressure in the system has been released.
The operator MUST NOT conduct any risky operations or those not required for the cutting in course
(e.g. remove swarf shavings from the machine while cutting).
Never move the saw while the machine is operating.
Always keep the workplace are as clean as possible.
Remove equipment, tools or any other objects from the cutting zone.
Support the work piece on both sides of the machine to prevent it falling or jamming during the
cutting cycle.
Page 14
Instruction Manual for VS315D (S040)
04/04/2019

Brobo Group
Ensure that the specimen being cut is secured firmly in the vice clamps and the machine has been
correctly set. Figure 7 show some examples on how to correctly clamp different specimen profiles.
Before commencing the cut, be sure the vice(s) is securely clamped and the machine set-up is
correct.
Figure 7. Correct Clamping of Cutting Specimens
Do not use cutting blades of different sizes to those recommended to the machine’s
specifications. Always follow safe practices and inspection procedures when installing blades
(Please refer to section 5.1 Changing the Blade).
When cutting very small specimens, ensure that the workpiece is not dragged behind the back
fence support, where it could get lodged behind the blade.
If the blade jams during a cut, activate the emergency stop function immediately. Do not
continue forcing the blade through. This could damage the blade, the specimen or be a cause for
potential injury to the operator.
Always turn off the machine before carrying out any repair work. Consult the Brobo Group
Engineering Department in the country in which the machine was initially purchased.

CHAPTER 3 - Main Functions and Operation of the Machine
3.1.1. Cutting Head
As the name suggests, the cutting head is the focal area where most of the specimen cutting takes place. Thus,
correct saw blade selection such as size, number of teeth and tooth pitch are all critical factors that determines the
overall performance and quality of the final cuts. In addition, the use of correct saw blade provides minimum burr to
the work piece while maximising the safety to the operator during each cutting procedure.
3.1.2. Saw Safety Guard
The primary purpose of the saw safety guard is to
protect the user from the spinning blade. It also
functions as a safety device to protect the operator
from any broken tooth, swarf or high-velocity
particles that might be dislodged by the cutting
process.

The following procedure is recommended for the correct cutting using the BW S315/S350/S400 Series Metal
Cutting Saw.
PROCEDURE
Using a non-flammable and toxic free solvent, clean the machine to remove any corrosion protective coating prior
to use.
1) Ensure that both the air and electric power systems are turned on, where applicable. The electrical power
source must be available before any pneumatic functions will operate.
2) To adjust the angle of the cutting surface, if necessary, loosen the 4
bolts, as shown in Figure 10. Fine-tune the angle required, then replace
and re-tighten the 4 bolts.
3) Place the cutting specimen you wish to cut into the vice clamps.
Manually adjust the clamps so that the jaws are clamped firmly to the
workpiece. With a pneumatic vice, manually adjust the clamps to a
clearance of 3 - 7mm. (For correct clamping of material, please refer to
section 2.3 Advice for the Operator). NOTE -The vice clamps advance
with an approximate 10mm pneumatic stroke to apply a clamping
pressure of 6 bar (87 psi).
4) Position the vice clamps and component as close to the blade as possible without interfering with the travel
of the blade or guard. Vice relocation is required whenever the head angle is altered.
5) For pneumatic vices, set the vice clamping pressure from the pressure regulators located on the main control
unit door. If for any reason this pressure is not available on a continuous basis, the regulator on the air
service unit must be set slightly below the available line pressure, and the safety low-pressure indicator
valve needs to be reset to correspond with the new available pressure. The need to change the pressure
is necessary to allow for lighter materials with hollow cross sections to be cut without deforming the walls
thicknesses.
6) To initiate the cutting process, either turn the switch to 1 or 2 settings, or press the START buttons.
 Vice jaws automatically close and applies clamping pressure.
 Position blade to commence cutting through component and maintaining a constant forward feed
cutting rate until the end of the stroke.
 Return saw cutting head to the initial rest position.
 Vice clamps release workpiece
7) Machine is ready for the next cutting cycle.
WARNING - BLADE JAMMING
If the saw blade jams during a cut, engage the EMERGENCY STOP immediately. Remove the part,
check that the blade is not damage and if need be, replace the blade.

3.3. Operation Recommendations
 Select the correct saw blade with the correct tooth pitch and form to suit the material to be cut to provide
minimum burr and maximum blade lifespan.
 Use the smallest diameter blade and coarsest pitch that is practical within the required speed and material
limitations.
 Generally use a tooth pitch to give 2 - 4 teeth engagement with the material during cutting.
 Ensure that sufficient coolant is flowing over the cutting teeth.
 Do not allow the machine’s gearbox to run idle in the upright position for more than 3 minutes otherwise,
damage can occur to the drive system.
 The rate of feed affects the quality of the final cut and blade life. This varies also by the material and cross-
sectional dimensions. When cutting stainless steel or high carbon steel (Brinell hardness above 200), the
slowest speed machine should be used together with a cobalt type high speed steel blade.
 When manually feeding the saw head, keep in mind to maintain a steady, continuous pressure, thus
avoiding work hardening on the cutting piece. Avoid ‘forcing’ the blade through the material as this might
damage or break the blade.
 As a rule of thumb the softer the component, the faster the rate of speed. Thus, it is recommended that
slower speeds be used for hard and tough materials and higher speeds for soft, ductile materials. Note that
for non-ferrous materials such as brass, copper, aluminium etc. require much faster speeds than provided
on this machine. If these are the majority of materials cut, a Brobo NF Series machine should be considered.
