Restarting
In the Event of a Blockage
If a blockage in the collection hose of the machine occurs, switch it off
immediately by pressing the power switch to the off position and wait for the
machine to come to a complete stop before proceeding further.
Unplug the machine from the power source and remove the blockage from the
collection hose. To re-start the machine press the power switch to the
on position.
In the Event of a Power Failure
In the event of a power failure, first turn the power switch to the off position and
then locate and rectify the source of the failure. If the fault is within the power
circuit of the workshop, there may be an underlying cause (circuit overload
etc.) that should be investigated by a qualified electrician, before attempting to
restore the power source.
Once the power is restored, the machine can be re-started by pressing the switch
to the on position.
8. Electrical Connection & Wiring Diagram
Machines supplied for use in the UK are fitted with a 3 pin plug conforming to
BS1363, fitted with a fuse conforming to BS1362 and appropriate to the current
rating of the machine.
Machines supplied for use in other countries within the European Union are
fitted with a 2 pin Schuko plug conforming to CEE 7/7.
Machines supplied for use in Australia & New Zealand are fitted with a 3 pin
plug conforming to AS/NZS3112.
In all cases, if the original plug or connector has to be replaced for any reason,
the wires within the mains power cable are colour coded as follows:
230 V (Single Phase)
Brown:
Live (L)
Blue:
Neutral (N)
Green and Yellow: Earth (E)
The wire coloured brown must always be connected to the terminal marked ‘L’ or
coloured red.
The wire coloured blue must always be connected to the terminal marked ‘N’ or
coloured black.
The wire coloured green and yellow must always be connected to the terminal
marked ‘E’ or with the earth symbol:
or coloured green / green and yellow.
It is important that the machine is effectively earthed. Some machines will be
clearly marked with the double insulated logo:
In this case there will not be an earth wire within the circuit.
In the case of the BS1363 plug for use in the UK, always ensure that it is fitted
with a fuse conforming to BS1362 appropriate to the rating of the machine. If
replacing the original fuse, always fit a fuse of equivalent rating to the original.
Never fit a fuse of a higher rating than the original. Never modify the fuse or fuse
holder to accept fuses of a different type or size.
Where the current rating of the machine exceeds 13 A at 230 V, or if the machine
is designated for use on a 400 V 3 phase supply a connector conforming to
BS4343 (CEE17 / IEC60309) will be used.
230 V machines will be fitted with a blue 3 pin connector. The wiring for this type
of this connector will be the same as shown above.
400 V, 3 phase machines will be fitted with a red 4 or 5 pin connector. The wiring
for this type of connector is as shown below:
400 V (3 phase)
Brown:
Live (L1)
Black:
Live (L2)
Grey:
Live (L 3)
Blue:
Neutral (N)
Green and Yellow: Earth (E)
The wire coloured brown must always be connected to the terminal
marked ‘L1’.
The wire coloured black must always be fitted to the terminal
marked ‘L2’.
The wire coloured grey must always be connected to the terminal
marked ‘L3’.
The wire coloured blue must always be connected to the terminal
marked ‘N’ or coloured black.
The wire coloured green and yellow must always be connected to the terminal
marked ‘E’ or with the earth symbol
If in doubt about the connection of the electrical supply, always consult a
qualified electrician.
