2.3. 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 the course (e.g. remove swarf shavings from the machine while
cutting). Never move the saw while the machine is operating.
Always keep the workplace 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 from falling
or jamming during the cutting cycle.
Bro b o G ro up brobo.com.au
Ensure that the specimen being cut is secured firmly in the vice clamps & the
machine has been correctly set. Figure A shows 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.
Figure A. 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 & 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.

8. STAND
3.1.1. Cutting Head
Figure 8. Saw Main Components
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 & tooth pitch are all critical factors that determine the overall performance & quality of the final cuts. In addition, the use of the correct saw blade provides minimum burr to the workpiece while maximizing the safety of the operator during each cutting procedure.
3.1.2. Saw Safety Guard
The primary purpose of the saw safety guard (Figure 9) 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 highvelocity particles that might be
dislodged by the cutting process.
Figure 9. Saw Safety Guard
Bro b o G ro up brobo.com.au
3.1.3. Hydrocheck Unit
The hydrocheck unit (Figure 10) is a precision built self-contained hydraulic
control unit designed to smooth out pneumatic cylinder movement for cold
cutting: The piston speed is controlled on the stroking stroke by pushing oil
from one side of the piston to the other via a transfer tube and needle valve
which adjusts checking rate.
3.1.4. Pneumatic Vice Clamp
Operating at 600kPa, the vice clamps (Figure 11) firmly secure the workpiece
in preparation for cutting. The pressure of each vice clamp could be modified
using the pressure regulator located on the main electrical unit door. Each
vice must be adjusted manually to accommodate various cross-sectional
profiles.
Optional Upgrade Heavy Duty Pneumatic Vice (Figure 12). This upgrade will
provide increased stability and holding capacity, allowing for more efficient
and precise cutting of metal materials. The pneumatic functionality ensures a
strong and reliable grip on the workpiece, minimizing any potential slippage
or displacement during cutting.

3.1.5. PLC ENCLOSURE
Figure 13. PLC Control Box
Cutting Speed Selection The Brobo Group SA350/400 Semi-Automatic Saw comes
with a fully adjustable feeding speed. The feeding speed is adjusted at the
Feed Rate control valve (Figure 13). The hydrocheck unit feeds at constant
force hence the cutting speed will vary also according to the thickness of the
cut section. The recommended cutting RPM for Mild Steel is 40 to 60 RPM, for
galvanized & stainless steels the recommended cutting speed is 20 to 25 RPM.
Dual Start Button The primary purpose of the dual start buttons is to prevent
the user from accidentally activating the machine. Assuming that the power is
connected to the machine, both buttons must be depressed simultaneously before
the cutting cycle will activate. End Cut Detect Button The SA350/400 Saw
completes a cut using an auto-detect system for determining when it has cut
through the piece. This ensures that the saw completes the cut in the fastest
possible time. This system works reliably on all RHS & round sections,
however, for some profile sections, it will fail to detect the end of the cut
& finish cutting too early. The operator can turn this on/off using the END
CUT DETECT button. When switched off the saw makes the deepest possible cut
It is also possible to limit the cut depth while END CUT DETECT is on by unscrewing the depth adjustment screw while tightening the screw increases the cut depth. (Figure 14)
Emergency Stop Press the Emergency Stop Button during any operation to immediately stop the
saw.
The saw must be recalibrated after the emergency stop.
(Please refer to section 3.2 Preparation for Operation) When the Emergency Stop Button has been pressed the ‘ON’ light will turn off.
Figure 14. Adjustment Screw
Wait 5-10 seconds then release the emergency stop button.
To release the emergency stop button from the depressed position simply twist it in the clockwise direction.
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.
Bro b o G ro up brobo.com.au
3.2. Preparation for Operation
The following procedure is recommended for the correct cutting using the Brobo
Group SA350/400 Semi-Automatic Saw
WARNING SAFETY GEAR Protective clothing, safety glasses and gloves should
always be worn while loading parts, operating the machine, or undertaking any
maintenance work on the saw.
PROCEDURE
1. Cleaning Using a non-flammable & toxic-free solvent, clean the machine to
remove any corrosion protective coating before use.
2. Power On Ensure that both the air & electric power systems are turned on,
where applicable. The electrical power source must be available before any
pneumatic functions will operate.
WA RNING – BLA DE C HA NG E
Calibration of the saw must be done after every blade change. Not doing so may
result in the blade cutting into the base of the saw or actuator jamming.
Ensure that the saw is turned off during blade changes.
3. Angle Adjustment
To adjust the cutting angle, untighten the quick action handle, as shown in Figure 15. Fine-tune the angle required, then re-tighten the quick action handle.
4. Vice Clamp Setting
Place the cutting specimen you wish to cut into the vice clamps. With a pneumatic vice, manually adjust the clamps so that the jaws are clamped firmly to the workpiece or with a clearance of 3 – 7mm. (Figure 16) (For correct clamping of material, please refer to section 2.3 Advice for the Operator).
Figure 15. Quick Action Handle
Position the vice clamps & 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.
Figure 16. Clamp Clearance 3-7mm
5. Vice Clamp Pressure For pneumatic vices, set the vice clamping pressure from the pressure regulators located on the main control unit door. The vice clamps advance with an approximate 10mm pneumatic stroke to apply a clamping pressure of 6 bar (87 psi).
If for any reason this pressure is not available continuously, the regulator on the air service unit must be set slightly below the available line pressure, & the safety low-pressure indicator valve needs to be reset to
Bro b o G ro up brobo.com.au
correspond with the newly available pressure. The need to change the pressure
is necessary to allow for lighter materials with hollow cross sections to be
claimed without deforming the material.
6. Toggle Switch UP & Down
To manually adjust the saw head position, you will need to toggle the Toggle
Switch up and down position. Toggling the switch up will raise the saw head
while toggling it down will lower it (Figure 17)
7. SET TOP POSITION
Toggle the saw head down to be 10mm above the cutting material. Press the SET
TOP button to set the top position of the saw head
(Figure 18).
Figure 17. Toggle Switch
8. SET END CUT POSITION
Make sure the cutting material is not under the saw blade. Toggle the saw head
down where the blade just passes thru the
cutting material. Press the SET BOTTOM button to set the end cut position
(Figure 19). The saw will then move up to the Set Top Position, ready for
cutting
operation.
Figure 18. SET TOP Figure 19. SET BOTTOM
9. Dual CUT Button When ready to cut, place the material under the blade in the desired cutting position Press the two CUT buttons simultaneously, (Figure 20) The vices will clamp the workpiece, the blade will start rotating & the saw head will lower to cut the piece. Once the cut is complete the vices will release the workpiece & the saw head will return to the set-top position, ready to cut the same piece again. To continue cutting this piece, simply place more cutting materials in the vice & press two CUT buttons simultaneously.
Figure 20. Dual Cut Bottons
WA RNING – BLA DE MO TO R O VERLO A D
Saw is equipped with overload monitoring system which detects main motor overload in case
of blade jam or inadvertent misuse. In case of overload saw reverses feed, re- establishes
correct running of motor & continues the cut. If the saw overload system is reversing feed
regularly during a cut, it indicates the blade is worn. Replace the blade promptly at this
occurrence changes.

10. Spindle RPM
By pressing the spindle RPM button, you can increase or decrease the speed at
which the spindle rotates, depending on your needs and the requirements of the
specific task you are performing (Figure 21)
Low-medium speed (21-42 RPM) for stainless / galvanised steel applications
Medium-high speed (42-85 RPM) for mild steel applications
Figure 21. Spindle RPM
11. Feed Rate
Adjust the feed rate to control the saw head speed coming up & down (Figure
22)
3.3. Operation Recommendations
Figure 22. Speed Rate
Select the correct saw blade with the correct tooth pitch & form to suit the
material to be cut to provide minimum burr & maximum blade lifespan. o SA350
Blade Sizes 320-350 mm o SA400 Blade Sizes 350-400 mm
Use the smallest diameter blade & coarsest pitch that is practical within the
required speed & 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 & blade life. This
varies also by the material & crosssectional 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.
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 & tough materials
& higher speeds for soft, ductile materials. Note that nonferrous materials
such as brass, copper, aluminium, etc. require much faster speeds than those
provided on this machine. If these are the majority of materials cut, a Brobo
NF Series machine should be considered.

CHAPTER 5 – Adjustments to the Saw Unit
5.1. Changing the Blade
To replace a worn saw blade:
DA NG ER ELEC TRO C UTIO N
Make certain that the power to the saw is turned off before proceeding with
changing the saw blade.
- Disengage the linkage arm that is between the guard linkage system & pivot block (at the pivot block by compressing the spring & moving the bolt through the slot).
- Slide the saw guard up as far as possible (as if it was opening during a cutting cycle) to gain access to the spindle nose.
- Loosen the spindle screws (LH thread), using the 14mm hexagonal wrench provided, & remove the counter plate. To loosen the spindle screw, insert the wrench (short end) into the socket head cap screw & firmly knock the wrench with the palm of your hands until the screw is loosened. If this method fails to free the screw, place a piece of timber under the blade of the machine, & loosen (or tighten) the screw while holding the saw head of the machine down (blade against the timber).
- Remove the worn saw blade away from the spindle hub. Using a soft brush, clean the face of the spindle, counter plate & mounting faces of the blade of any dirt or swarf that was trapped by the previous cutting cycles.
- Place the old saw blade into the new blade packaging & disposed of it safely. Carefully mount the new blade onto the spindle hub, ensuring that the blade is rotating into & towards the back fence, & replace the counter plate utilizing the drive pins as guides as it passes through the pinholes on the blade.
- Rotate blade back against the drive pins in a counter-clockwise & finger-
tighten the spindle screw. 7) Firmly retighten the spindle screws, ensuring
that the saw blade spins uniformly & aligned parallel with the
safety guard. 8) Lower the outer guards & make certain the pin of the linkage arm is re-engaged with the track on the inner
guard & reconnect the guard linkage. 9) The new blade is ready for use. To check that the blade is performing correctly, carry out a sample cut on
a piece of off-cut. 10) If optional devices are supplied, mount the stock support & rollers on either side of the clamping table.
Normally stock should feed the left to right, but it can be fed from right to left if required.

5.2. Adjusting the Cutting Angle
The back jaw wear plates on the Brobo Group SA350/400 Semi-Automatic Saw are
typically fitted in the following manner. For angular cutting, the wear plates
should be repositioned to provide maximum support on one side & clearance on
the other (Figure 23).
Standard Cut
Angular Cut 450
Figure 23. Angular Cut Positions
i. To adjust the cutting angle, untighten the quick action handle, as shown in
Figure 15. ii. Adjust the angle on the rotary table to suit. (Self-locating
pin locates at 900 & 450 left & right) iii. Re-tighten the quick-action
handle. The saw is now ready for use.
5.3. Cutting & Feeding Speeds
As previously highlighted, the rate of feed largely affects the quality of the
final cut. As such, the blade life is also dependent on the feed at which it
is cutting the sample material – in particular, the type of material & also
the crosssectional dimensions. Thus, to extend the life of the blade, maintain
a firm & steady pressure whilst allowing the blade teeth to cut at an optimum
rate. Do not force the blade through the material! This could cause numerous
problems including breaking the blade teeth, jamming the blade with the
cutting part, or fracturing the blade spindle. The cutting action also
generates a large amount of heat within the cutting sample due to frictional
contact. Should this heat affect the material you are cutting in any way, the
heat should be dissipated using the coolant system.
5.4. Refilling the Lubricator
To refill the lubricator bowl, twist the bowl anti-clockwise & slide it down
to detach it from the lubricator unit (There is no need to disconnect the air
supply to the unit). The unit can now be refilled to the line positioned near
the top of the bowl, which is approximately 10 millimeters from the top edge
of the bowl. Do not fill the bowl above this line, as the lubricator unit will
not function properly. Replace the lubricator bowl in a reverse manner by
sliding the bowl upwards, ensuring that the feed tube is located inside the
bowl, & twist it clockwise to lock it into position.

5.5. Adjusting the 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. There are 2 control variables available for the operator:
Air Flow (Volume) Delivery Regulated with the tap (needle valve), this can be
adjusted from initial, completely closed to fully open states. It is highly
recommended that the upper end of the flow range be utilized to allow adequate
airflow to deposit & evenly distributed the lubricant onto the blade while
maintaining a fine lubricant mix. If the needle valve is not open
sufficiently, the air to lubricant ratio may vary & may result in a
substandard distribution of lubricant to reach the blade teeth.
Lubricator Flow Rate This controls the fluid flow rate & is adjustable via the
slotted needle valve situated on top of the lubricator. The consumption of
Brobolube is factory set to 4 drops per minute. This has been examined to
produce a sufficient mix of air & lubricant, & it is recommended to use this
initial setting. In this setting, approximately 55 cubic centimeters
(lubricator capacity) should last for 20 hours of continuous cutting. If for
some reason the setting needs to be altered, the needle valve should be turned
clockwise to reduce or anti-clockwise to increase the fluid flow respectively.
NOTE i. 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 a swarf that will be wet (oily)
& harder to clean up than dry swarf
produced from the correct supply of Brobolube. ii. The amount of Lubricant
(when set correctly) delivered by the lubricator is not easily visible to the
naked
eye. If in doubt that lubricant is being delivered, first check to see if the
lubricator itself is delivering droplets at its sight glass. If still unsure
whether lubricant is being delivered, disconnect the supply tubing to the tap
(needle valve) & hold the tube against some blotting paper for a few seconds
while the lubricator is operating.

5.5.1. Lubricating Oil Precautions – Health Hazard Information
The Brobolube lubricating fluid has no known adverse health effects.
“Brobolube” is non-toxic, odourless, nonflammable below approximately 350ºC, &
non-corrosive, although it may affect some types of rubber. There are no
traces of sulfur, 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 the 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 & 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.

Check to ensure that other operators of the machine are always aware of and
comply with the relevant safety instructions & standards as specified in
Chapter 2 – Safety & Accident Prevention. Therefore, check that the safety
devices are operational & work perfectly and that personal safety requirements
are complied with.
Ensure that the working cycle is efficient & guarantees maximum productivity,
inspect the: o Functions of the main components of the machine o The sharpness
of the blade & coolant flow o 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.
6.2. Maintenance Requirements
All maintenance must be carried out with the power switched off & the machine
in emergency stop condition.
To guarantee 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 the use & maintenance of the
machine, and those on the product itself.
6.3. General Maintenance of Functioning Components
The general maintenance operations that should be carried out regularly are as
follows:
-
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.
-
Observe the oil level on the gearbox. The first oil change should be performed after the initial 60 hours of operation & 500 hours of operation thereafter. Use Brobo Gearbox Oil (Part No. 9501090)
The refilling point is situated in the handle bar mounting threaded hole. The required quantity to refill is 800 ml for the S315/S350/400 gearboxes.
Bro b o G ro up brobo.com.au -
Change coolant as required, or whenever the coolant starts to get dirty or emits a stale odour. The coolant compensation tank should be checked regularly. Coolant levels would expect to naturally decrease over time due to natural evaporation. Use premium quality coolants such as CoolTech 500 or SlideTech 68. Coolant is available from BROBO GROUP Pty. Ltd. in 2 litre & 20 litre packs (Part No. 9301570 & 9501080): Concentrate, Ratio 1:20
-
Lubricate the saw head pivot shaft & 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.
-
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 them 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. 9) Test that the blade is at right angles to the workpiece back fence.
If not, contact Brobo Group engineering department. 10) Check that the 0 notch on the fixed worktable is aligned with the graduation on the turntable. If not, adjust
as described in Section 5.2. 11) Examined that the precision of the 15, 30, 45 left & right stops are correct & accurate. If they are not
adjusted properly, proceed as described in Section 5.2. 12) Regularly empty out the swarf catcher, resting directly above the compensation tank, of any offcuts & swarf
that have collected during the numerous cutting cycles.
