TABLE 2. Blade Selection Chart
NOTE - CHART GUIDE ONLY
This chart is issued as a guide only. Many other factors would attribute to the cutting
performance of both the saw blade and the cutting saw machine. BROBO GROUP Pty. Ltd.
will not accept any responsibility for the blade selection and/or machine breakages or
unsatisfactory cutting performance of both the blade and/or the machine as a direct result of
the selection.

Brobo Group

Reduces galling or "pick-up" on sides of the blade,
Reduces brittleness of the steel.
Tooth Form: Bevelled on alternate sides - up to 180 teeth, or
High-rolling, low-finishing teeth, "triple-chip" - above 180 teeth
Drive Pin Holes (Qty. PCD): S315 & S350 Series 2 8mm 55mm

CHAPTER 1 - Installation of the Machine
1.1. Unpacking & Handling the Machine
Upon receiving the Brobo Group S315/S350/S400 Series Metal Cutting Saw, the machine should be standing
upright & positioned centrally on top of a wooden pallet. While the machine is situated on the pallet, position the
forklift arms under the pallet between the runners, keeping in mind that the machine is head heavy. Move the entire
unit to an accessible area as close as possible to the final location.
Carefully remove the wooden frame surrounding the saw unit (Figure 1). Once completed, proceed by elevating the
machine away from the pallet base using a sling harness wrapped around the cutting head of the saw. Ensure that
the floor is as level as possible before finally positioning the machine to the desired location.
FIGURE 1. Handling of Metal Cutting Saw Unit
PLEASE OBSERVE & FOLLOW THE INSTALLATION INSTRUCTIONS ON PAGE 7
WARNING – HEAD HEAVY MACHINES
The metal sawing machines are heaviest where the saw heads are fitted & as such, care must
be taken while relocating or moving the machines.

1.3. Minimum Requirements
For the machine to function correctly, the room in which the saw unit is to be installed must be in the vicinity of, &
satisfy the following conditions:
415/240V Power Supply
Ambient Temperature - From -10
 C to +50  C.
Relative Humidity: Not more than 90%.
Lighting: More than 500 LUX.
WARNING – OPERATING VOLTAGE VARIATION
Each saw model has an inbuilt safety system to protect it against voltage variations. However,
for the machine to perform efficiently, ensure that the saw unit operates within
 10% limits of the
recommended voltage of the motor.

1.4. Anchoring the Saw
Prior to anchoring the saw unit, take into considerations the requirements mentioned in Section 1.3 & Section 2.2,
& other aspects regarding the usage of the machine such as accessibility to cut parts & safe access for the operator.
The base of the fabricated stand (if applicable), in which the saw head rests on, is anchored to the floor by 4 M12
bolts provided. For added stability, it is strongly recommended that the machine stand is fastened to the floor by
using loxins (not provided). When positioning & fastening the unit, please refer to the hole locations shown in Figure
2.

1.5. Connection to Power Source
Before connecting the machine to the power supply, check that the socket is not connected in series with other
machines. This condition is critical for the ideal operation of the saw unit.
Single & Three Phase
a) Single phase machines are provided with three pins, 15 amps rated plugs & leads for connection to 240V,
50Hz power supply in Australia.
Figure 3.1 Connection 3 pins – 1 Phase
b) Three phase machines should be fitted with a suitable, approved four pin plugs
(i.e. three phase & earthing - not provided)
Figure 3.2 Connection for “4-CORE” Wire System with Neutral – 3 Phase
c) Check the power supplied & motor specifications before plugging in the machine. Check the terminal
connection on dual voltage motor terminal box & connect it accordingly to the corresponding voltage supply.
d) If the dual motor is requested, the motor is always connected to the higher voltage, unless otherwise
specified prior to the order being placed.

To connect the machine to the power supply, proceed as follows:
1) Insert the power plug into the socket, while ensuring that the mains voltage is compatible for which the
saw unit is operating at.
2) Switch the saw on by rotating the control switch located on the saw head assembly as shown in Figure 4
below.
Figure 4. Main Control Switch
3) Check that the motor is operating in the correct direction, that is the blade is rotating downwards & into the
direction of the vice clamps.
4) Ensure that all electrical leads & cables (including supply leads) are maintained in a good condition &
away from sharp objects. All leads should be replaced if cut, sliced or damaged in any way.
Brobo Group S315/S350/S400 Series Metal Cutting Saw is now ready for use.
