General Instruction for 230V Machines
7
These machines are supplied with a moulded 16 Amp
plug and 3 core power cable. Before using the machine,
inspect the cable and the plug to make sure that neither
are damaged. If any damage is visible, have the damaged
item inspected/repaired by a suitably qualified person.
If it is necessary to replace the plug, it is preferable to
use an ‘unbreakable’ type that will most resist damage.
Only use a 16 Amp plug, and make sure the cable clamp
is tightened securely. Fuse as required. If extension leads
are to be used, carry out the same safety checks on them,
and ensure that they are correctly rated to safely supply
the current that is required for your machine. Remember,
most machines or tools have handles or holding
positions, the power cable is not one of them.
Good Working Practices/Safety
Mains Powered Tools and Machines
Primary Precautions
Workplace/Environment
The following suggestions will enable you to observe
good working practices, keep yourself and fellow
workers safe and maintain your tools and equipment in
good working order.
WARNING!! KEEP TOOLS AND EQUIPMENT OUT
OF THE REACH OF YOUNG CHILDREN
KEEP THE WORK AREA AS UNCLUTTERED AS
IS PRACTICAL,THIS INCLUDES PERSONNEL
AS WELL AS MATERIAL. UNDER NO
CIRCUMSTANCES SHOULD
CHILDREN BE ALLOWED IN WORK AREAS.
The machine is not designed for use outside. Keep the
machine clean; it will enable you to more easily see any
damage that may have occurred. Clean the machine with
a damp soapy cloth if needs be, do not use any solvents
or cleaners, as these may cause damage to any plastic
parts or to the electrical components. It is good practice
to leave the machine unplugged until work is about
to commence, also make sure to unplug the machine
when it is not in use, or unattended.To avoid inadvertent
‘start up’, if your machine is not fitted with a NVR system,
ensure the switch is always returned to the OFF position.
Once you are ready to commence work, remove any
tools, objects or items that could inadvertently get
‘sucked up’ by the machine and place safely out of the
way. Re-connect the machine, ensuring the power cable
is not ‘snagged’ or routed where it could be tripped over
as you move about the workshop; it is not too close to
an unguarded heat source, or is laid over or around a
sharp edge. If the work you are carrying out is liable to
generate flying grit, dust or chips, wear the appropriate
safety clothing, goggles, gloves, masks etc. If the work
operation appears to be excessively noisy, wear
ear-defenders. If you wear your hair in a long style,
wearing a cap, safety helmet, hairnet, even a sweatband,
will minimise the possibility of your hair being caught
up in the rotating parts of the machine, likewise,
consideration should be given to the removal of rings
and wristwatches if these are liable to be a‘snag’ hazard.
Consideration should also be given to non-slip footwear,
etc.
Do not use this machine if you are tired, your attention is
wandering or you are being subjected to distraction.
Do not use this machine within the designated safety
areas of flammable liquid stores or in areas where there
may be volatile gases.There are very expensive, very
specialised machines for working in these areas. Above
all, OBSERVE…. make sure you know what is happening
around you, and USE YOUR COMMON SENSE.
Specific Safety for Dust
Extractors
Do not use this machine as a vacuum cleaner, try to keep
the waste medium to wood by products.
Do not uplift workshop floor debris (stones, nails, screws,
paper etc., etc). Be aware that wood dust is an explosive
medium.
Do not allow any‘naked light’ source to occur anywhere
near the machine.This includes cigarettes, matches, etc,
and do not place the machine near any unprotected
light bulbs, that could possibly get broken.
The suction force is generated by a high speed fan unit.
This has the potential to amputate fingers, grab loose
clothing (ties etc.,) and‘bat’ large chips etc, at high
speeds. Keep all guarding in place, and if access to the
fan becomes necessary (due to blockage etc.,)
Disconnect the machine from the mains supply and
ensure the fan has come to a complete stop before
putting your hands anywhere near to it.
If you are not using ‘clear’ extraction hose, periodically
remove the hose to check that the inlet to the machine
is not getting restricted. (The safety guard grill of the
inlet duct can be particularly irksome in this way, as long
strand shavings etc., can wrap around the grill fret.)
Keep the particle filter clean.The machine relies on its
ability to ‘blow’ air through the filter, to generate good

Specific Safety for Dust Extractors
8
suction. If the particle filter starts to clog, this reduces the
air flow and hence the machine becomes less efficient.
The particle filter can be cleaned, by using an ‘M’ class
vacuum cleaner, clean the inside of the filter.
Be aware that in dry air periods or areas, the movement
of the air through the machine can generate static
electric fields.These are not normally a problem as the
machine is bonded together via its construction and
the whole is earthed back through the electrical supply;
problems can occur with isolated items, such as stands
or hosing that are insulated from the ground (standing
on rubber feet?, suspended in the air etc).
If possible, try to connect everything together electrically,
to eliminate static shocks.
(Use the integral metal coil in flexible plastic hosing to
connect units together).
Try to route the power cable and the hosing away from
busy walkways.
Do not allow the inlet to become‘dead ended’, or block
or restrict the outlet, this puts undue strain on the motor
and can lead to overheating.
NOTE: DO NOT FIT PLASTIC WASTE BAGS TO THIS MACHINE!

Maintenance
Many manufacturers will state the volume of air required for each machine in their manual. If
not, note the size of the extraction port and use the chart below
Basic design
• Keep it simple, don’t over complicate the system.
• Keep it straight, ducting runs should all be straight with as few bends as possible.
• Keep transfer duct as big as required by the extractor, this should get larger towards the
extractor.
• Keep fl exible duct to a minimum. If the machine cannot be connected to the system by
solid ducting only then should flexible ducting be used for the final connection.
• Keep branches joining the duct to a maximum of 45° When branches join the main duct
ideally they must enter at the side or the top at an angle of a maximum of 45° towards the
direction of flow.
• Fit Blastgates to maximise effi ciency and balance the system.
The negative pressure inside the ducting draws air into the system. Incorrect sizing of the
duct, too many bends coupled to lots of flexible hose induces losses into the system and in
badly designed systems this is akin to leaving the hand brake on in a vehicle.
Example: for a single machine with a 100mm port an extractor of a minimum of 700m³/hr
will be sufficient. For multiple machines count the number of extraction ports per size,
multiply the number of each size by the volume of air required.Then add the results
per outlet size to give you a total volume of air required.This total is for all the machines
operating at the same time.You then must decide which and how many machines will be
used at the same time. Divide the total volume of air required by this number and add 500m³/
hr. Choose an extractor that gives the airflow required by your calculations. Look at the main
inlet size of the extractor, this is the size of the main duct to be used. In larger systems the
ducting should get larger towards the extraction unit as more machines that are in use are
added to maintain the correct air speed in the duct.This is very important; if the airflow is too
low a build up of dust and debris will occur and is a fire and explosion risk. If the air speed is
high then the system will be noisy but there will be no deposits in the ducting. Always use
blastgates to close off airflow to machines that are not in use.
