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.

CHAPTER 1 - Installation of the Machine
1.1. Unpacking and Handling the Machine
Upon receiving the Brobo Group S315/S350/S400 Series Metal Cutting Saw, the machine should be standing
upright and 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 AND FOLLOW THE INSTALLATION INSTRUCTIONS ON PAGE 7
WARNING – HEAD HEAVY MACHINES
The metal sawing machines are heaviest where the saw heads are fitted and as such, care must be
taken while relocating or moving the machines.

For the machine to function correctly, the room in which the saw unit is to be installed must be in the vicinity of, and
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.

1.4. Anchoring the Saw
Prior to anchoring the saw unit, take into considerations the requirements mentioned in Section 1.3 and Section 2.2,
and other aspects regarding the usage of the machine such as accessibility to cut parts and safe access for the
operator.
The base of 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 be fastened to the floor by
using loxins (not provided). When positioning and 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 and Three Phase
a) Single phase machines are provided with three pins, 15 amps rated plugs and 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 and earthing - not provided)
Figure 3.2 Connection for “4-CORE” Wire System with Neutral – 3 Phase
c) Check the power supplied and motor specifications before plugging in the machine. Check terminal
connection on dual voltage motor terminal box and connect it accordingly to the corresponding voltage
supply.
d) If dual motor is requested, the motor is always connected to the higher voltage, unless otherwise specified
prior to order being placed.
