CHAPTER 1 - Installation of the Machine
1.1. Unpacking & Handling the Machine
Upon receiving the Brobo Group PEDESTAL GRINDERS PG350, the machine should be standing upright &
positioned centrally on top of a wooden pallet.
Carefully remove the packaging surrounding the pedestal grinder. Position the grinder to the desired location,
ensuring that a power outlet is available and within reach of the grinder power cord. Loosen the base bolts restraining
the grinder and sling a harness around the body of the unit while being mindful that equal weight distribution is
required to prevent it from tipping. Raise the pedestal grinder, slide the pallet away from the machine and re-lower
the grinder to the final location.
Prior to powering up the grinder, place the desired wheel/buff mop onto the machine spindles. Note that if the bore
sizes on the grinding wheels and/or buffering mops do not fit the spindle, taper adapters and buff adapters are
readily available for purchase from most hardware and tool outlets.
Once the wheels/buffs are securely fastened to the machine, connect the grinder to the mains electrical supply and
power up the machine.

WARNING – OPERATING VOLTAGE VARIATION
Each grinder model has an inbuilt safety system to protect it against voltage variations.
However, for the machine to perform efficiently, ensure that the grinder unit operates within
10% limits of the recommended voltage of the motor.

1.4. 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 grinder 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.
