Advice for the Operator

• Protective eyewear or goggles must be worn at all times while attending & 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 & arms are kept clear of the cutting zone when the machine is operating.

• Do not wear loose clothing with long sleeves & oversized 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 workpiece on both sides of the machine to prevent it falling or jamming during the cutting cycle.

• Ensure that the specimen being cut is secured firmly in the vice clamps & the machine has been correctly set. Figure A show some examples of how to correctly clamp different specimen profiles. Before commencing the cut, be sure the vice(s) is securely clamped & the machine set-up is correct.

• Do not use cutting blades of different sizes to those recommended to the machine’s specifications. Always follow safe practices & inspection procedures when installing blades.

• 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.

  • Functions of the main components of the machine
  • The sharpness of the blade & coolant flow
  • Correct working parameters for the type of material being cut
• Verify that the quality of the cut meets the requirements & the final product is free from any machining defects.

Maintenance Requirements

• All maintenance must be carried out with the power switched off & the machine in emergency stop condition.
• To guarantee for optimum operation, all spare parts must be Brobo Group originals.
• On completion of maintenance works, ensure that the replaced parts or any tools used have been removed from the machines before starting it up.
• Any behavior not in accordance with the instructions for using the machine specified in this manual may create hazards and/or safety risks for the operator.
• Therefore, read & follow all the instructions for use & maintenance of the machine, and those on the product itself.

General Maintenance of Functioning Components
The general maintenance operations that should be carried out regularly are as follows:

1. Keep the vice clamps, overall machine & path of the cutting blade free of any offcuts, accumulated swarf & coolant using compressed air or preferably thread-free cloth.
2. Change oil lubricant as required, or whenever the coolant starts to get dirty or emits a stale odour. The oil lubricant compensation tank should be checked regularly.
3. Recommended Brobolube Aluminium Cutting Oil, Part No:-
   • 9601480 Brobo Fluid – Aluminium Cutting Oil (2 Litres)
   • 9601481 Brobo Fluid – Aluminium Cutting Oil (20 Litres)
4. Lubricate the rotary table regularly (after every 40 hours of operation, or weekly) with an NLGI 2 extreme pressure grease, Shell Alvania No.1 grease or equivalent.
5. Clean the vice & lubricate any moving joints or sliding surfaces with good quality oil.
6. Clean the machine regularly & keep any unpainted surfaces lightly oiled to protect from rust & corrosion.
7.  The air supply for the pneumatic air vices should be checked regularly such that it is free of any condensed water molecules & the filter should be drained frequently.
8. Ensure that the machine performs cuts perpendicular to the work surface.
   If not, contact Brobo Group engineering department.

Brobolube Unit
When assembled, the Brobolube unit is a precise instrument that supplies an accurate quantity of lubricant directly to the saw blade before it contacts the workpiece.
Although the lubricator is capable of delivering a much higher flow rate of lubricant, it is suggested that you do not increase the flow rate excessively because:

• No significant increase in blade life or lubricating efficiency will be achieved (confirmed by test results).
• Excessive application of Brobolube will only result in a waste of fluid.
• The excessive application will produce swarf that will be wet (oily) & harder to clean up than dry swarf produced from the correct supply of Brobolube.

Lubricating Oil Precautions – Health Hazard Information

• The Brobolube lubricating fluid has no known adverse health effects. “Brobolube” is non-toxic, odourless, non-flammable below approximately 350ºC, & non-corrosive, although it may affect some types of rubber. There are no traces of sulphur, chlorine, phenol or nitrates found in Brobolube. When comes into contact with skin, the oil may be removed by wiping away the excess, then washing the contaminated area with detergent & water. If the oil is utilized at high temperatures, appropriate protective apparel should be worn as the oil could cause burns to skin or eyes. If splashed by hot oil, immediately run cold water over the burn area & apply first aid burn treatment.
• If the Brobolube delivery line breaks or becomes disconnected during operation, ensure that the air supply to the system is disconnected before repairing the problem.
• It is recommended that footwear with anti-slip soles be worn at all times. Any spills will result in potentially hazardous slippery surfaces & should be dealt with promptly to prevent physical injury resulting from falls. Do not use coarsely, combustible material like sawdust to soak up oil due to the potential risk of spontaneous combustion. Spilled oil should be transferred into non-porous containers of suitable strength. Any remaining oil should be cleaned up with sand or other non-combustible, absorbent material. Place the sand and oil mixture into containers & disposed of by an EPA approved landfill or alternatively, by a suitable non-polluting method.
• In addition, rags soaked in oil should not be burned. Do not pour oil down the drain, which would ultimately contaminate the water supply & pollute the environment.

For firefighting purposes, either use CO2, dry chemical or foam retardant to extinguish the flames.
