GENERAL SAFETY RULES
WARNING: Do not attempt to operate the machine until you have read thoroughly and understood
completely all instructions, rules, etc. contained in this manual. Failure to comply may result in
accidents involving fire, electric shock, or serious personal injury. Keep this owner's manual and
review frequently for continuous safe operation.
1. Know your machine. For your own safety, read the owner's manual carefully. Learn
its application and limitations, as well as specific potential hazards pertinent to this
machine.
2. Make sure all tools are properly earthed.
3. Keep guards in place and in working order. If a guard must be removed for
maintenance or cleaning, make sure it is properly replaced before using the
machine again.
4. Remove adjusting keys and spanners. Form a habit of checking to see that the
keys and adjusting spanners are removed from the machine before switched it on.
5. Keep your work area clean. Cluttered areas and workbenches increase the chance
of an accident.
6. Do not use in dangerous environments. Do not use power tools in damp or wet
locations, or expose them to rain. Keep work areas well illuminated.
7. Keep children away. All visitors should be kept a safe distance from the work
area.
8. Make workshop childproof. Use padlocks, master switches and remove
starter keys.
9. Do not force the machine. It will do the job better and be safer at the rate for
which it is designed.
10.Use the right tools. Do not force the machine or attachments to do a job for which they
are not designed. Contact the manufacturer or distributor if there is any question about
the machine's suitability for a particular task.
11.Wear proper apparel. Avoid loose clothing, gloves, ties, rings, bracelets, and jewellery
which could get caught in moving parts. Non-slip footwear is recommended. Wear
protective hair covering to contain long hair.
12.Always use safety glasses. Normal spectacles only have impact resistant lenses. They
are not safety glasses.
13.Do not over-reach. Keep proper footing and balance at all times.
14.Maintain the machine in good condition. Keep the machine clean for best and safest
performance. Follow instructions for lubrication and changing accessories.
15.Disconnect the machine from power source before servicing and when changing the
blade.
16.Never leave the machine running unattended. Turn the power off. Do not leave the
machine until it comes to a complete stop.
17.Do not use any power tools while under the effects of drugs, alcohol or medication.
18.Always wear a face or dust mask if operation creates a lot of dust and/or chips. Always
operate the tool in a well ventilated area and provide for proper dust removal. Use a
suitable dust extractor.

ADDITIONAL RULES FOR DUST EXTRACTORS
1. Dust extractors are frequently moved around the workshop. Make sure that mains cables and
extractor hoses are positioned in such a way that they do not present a trip hazard.
2. Do not pick up pieces of metal or chunks of wood.
3. Switch off and unplug the extractor before removing the collection bag and/or filter.
4. Do not allow the collection bag to become over full.
5. When necessary, wash, thoroughly rinse and completely dry the filter bag. Using a wet or damp
filter bag will reduce its efficiency as it will quickly become clogged.
6. Dispose of waste in accordance with local regulations.
7. DO NOT use without the filter bag and collection bag in place.
8. Keep hair, loose clothing, fingers, and all parts of the body away from the end of the suction hose.

Tighten with a 12mm spanner
Lift the Motor and Collector Body unit
above the support legs and then lower
it so that the brackets fit over the upper
end of the Leg.
Secure the Collector Body to the

Tighten with a 12mm spanner
Fit the Filter Bag Support
Push the Filter Bag Support into the 2
holes located in the rim of the collector
drum.
Firmly press down until it is fully seated
on both sides.
Fit the Handle
Attach the Handle using 2 Cross Head
Screws.
Fit 2 Foam Sealing Strips
Take a roll of Self Adhesive Foam, peel
off the backing paper and stick it to the
outside upper rim of the Collector Body.
Use a pair of scissors to trim off any
excess.
Repeat for the lower rim.
The foam helps to create an airtight
seal for the bags.
7
Fit the plastic Collection Bag
Open the bag and fit it over the outside
of the Collector Body rim.
Tip: If you find this step tricky, use a
couple of pieces of tape to secure the
plastic bag in place whilst fitting the
strap.
Fit the Bag Strap over the plastic bag,
so it sits on the foam strip.
Engage the spring latch into one set of
hooks and fasten it with the lever.
Ensure the plastic bag is sitting higher
than the Bag Strap all around the rim.
Fit the Filter Bag
Locate the rectangle opening on the
open end of the Filter Bag.
Feed the Bag Strap into the pocket all
the way around the full circumference
of the bag, until it can be seen in the
opening again.
Engage the spring latch into one set of
hooks and fasten it with the lever.
8
Fit the Hose
Place a Hose Clamp over the outside
of one end the Hose.
Push it onto the inlet, on the underside
of the Collector Body.
Use a cross head screw driver to close
the Hose Clamp until it is tight.
The second Hose Clamp can be used
on the other end of the hose to secure
it to a hose fitting or the dust hood of a
machine.
The Extractor is now ready to use.
Using the Extractor
Always start the extractor running before starting the dust producing machinery. Also allow the
extractor to run for 10 seconds after the other machine is switched off to allow dust in the hose
system to clear.
Empty the collection bag before it is overfull and dispose of the waste in accordance with the
current requirements of your local authority.
Please Note: Maximum recommended total hose length in use at any time is 3 metres. Longer
hose lengths may be used, but will reduce the performance.
When using the extractor with machines or power tools which have a smaller diameter connection,
it is recommended to run the 100mm diameter hose from the extractor up to the machines dust
outlet and fit the appropriate sized reducer at that point. This will maintain the airflow rate of the
unit. For some applications it may be more convenient to use a smaller diameter hose. This will
inevitably reduce the performance of the machine and the length of small diameter hose should be
kept to a minimum.
Optional Items
1 Micron Cartridge Filter Upgrade
The standard cloth filter, filters down to 2 microns.
This optional cartridge replaces the cloth bag and filters down to 1
micron without any loss in performance.
Reducers
Used to connect the extractor to power tools or
machinery with outlets smaller than 100mm diameter.

Troubleshooting
Reduced Performance
Rattling noise and vibration
Extractor will not start
Extractor does not run but buzzing noise
heard from motor
Extractor cuts out whilst running
Check the collection bag is not full.
Empty or replace the bag as required.
Check the filter bag is not clogged. Turn the
bag inside out and scrape the inside clean.
The filter bag can also be washed, ensure it
is completely dry before refitting.
Examine the hose system looking for
blockages. Remove the hose and clear out
the blockage.
Examine the hose and fittings for splits or air
leaks. Secure the leaks and replace any
worn hose.
Large pieces may be blocked by the inlet
grill. Remove the hose and Y-shaped
connector from fan housing and check for
pieces of wood or foreign bodies that are
unable to pass through the grill. Remove
them and reattach hose.
Check circuit breaker. Reset as required.
Loose wire. Remove the On/Off switch,
check the wires are pushed firmly onto the
terminals.
Failed switch. Replace the on/off switch.
Capacitor failure.
(For confirmation, spin the motor shaft by
hand. Press the start button whilst the shaft
is still rotating. If the motors now runs
normally, the start capacitor has failed.)
Replace the start capacitor.
Overheating. Leave the motor to cool and try
again.
