area. The same applies for general rules of occupational  
health and safety.  
8. Use safety accessories. Safety glasses and earmuffs  
should always be worn. A face or dust mask is also  
required if the sanding operation creates dust.  
9. Do not abuse the power cord. Never pull the cord to  
disconnect the tool from the power point. Keep the cord  
away from heat, oil and sharp edges.  
10. Secure the work piece. Use clamps or a vice to hold  
the work piece. It is safer than using your hand and

WARNING. When using power tools, basic safety precautions  
should always be taken to reduce the risk of fire, electric  
shock and personal injury. Also, please read and heed the  
advice given in the additional important safety instructions.  
11. Do not overreach. Keep your footing secure and  
balanced at all times.  
12. Look after your tools. Keep tools sharp and clean for  
better and safer performance. Follow the instructions  
regarding lubrication and accessory changes. Inspect tool  
cords periodically and, if damaged, have them repaired  
by an authorised service facility. Inspect extension cords  
periodically and replace them if damaged. Keep tool  
handles dry, clean and free from oil and grease.  
1. Keep the work area clean and tidy. Cluttered work  
areas and benches invite accidents and injury.  
2. Consider the environment in which you are working.  
Do not use power tools in damp or wet locations. Keep  
the work area well lit. Do not expose power tools to rain.  
Do not use power tools in the presence of flammable  
liquids or gases.  
13. Disconnect idle tools. Switch off the power and  
disconnect the plug from the power point before  
servicing, when changing accessories and when the  
tool is not in use.  
3. Keep visitors away from the work area. All visitors and  
onlookers, especially children and infirm persons, should  
be kept well away from where you are working. Do not

15. Avoid unintentional starting. Always check that the  
switch is in the OFF position before plugging in the tool  
to the power supply. Do not carry a plugged in tool with  
your finger on the switch.  
5. Do not force the tool. The tool will do the job better and  
safer working at the rate for which it was designed.  
6. Use the correct tool for the job. Do not force small  
tools or attachments to do the job best handled by a  
heavier duty tool. Never use a tool for a purpose for  
which it was not intended.

Introduction  
Attaching the hose  
C
The dust collection system is specifically designed to  
capture sawdust and woodchips. NEVER use as a vacuum.  
1. Fit the hose clamp (8) over the  
end of the hose (7) but do not  
tighten the clamp (fig. C).  
CAUTION. The dust collector housing features a high  
speed fan that can amputate fingers, grab loose clothing  
and neckties, or propel dust at high velocities.  
2. Fit the hose onto the inlet (2)  
(fig. D).  
CAUTION. This dust collector does not eliminate the need  
to wear a protective dust mask. Always follow the safety  
recommendations from the manufacturer or supplier of the  
material being cut and collected in the dust collector.  
3. Ensure it is pushed all the  
way on and is secure on the  
inlet cover.  
D
E
DO NOT OPERATE WITHOUT ALL PARTS  
IN PLACE!  
Do not attempt to clean, remove dust bags or service unit  
while in operation. Disconnect from the power source.  
Attaching the wheels  
The wheel castors allow the dust collector to be moved  
easily around the work area.  
4. Tighten the hose clamp using a flat end screwdriver to  
secure the hose on the inlet (fig. E).  
1. Place the dust collector on its side.  
2. Screw one castor wheel (5) into each corner of the base  
(fig. A).  
Attaching the 2 way adaptor  
The 2 way adaptor (9) allows up to 2 tools to be operated at  
the same time.  
1. Fit the hose clamp (8) onto the end of the hose (7) but do  
not tighten (fig. F).  
3. To secure the wheels onto the base tighten the hex nut  
on each wheel using a 14mm wrench (fig. B).  
Note. When fitting the last castor wheel, screw the wheel in  
sufficiently to allow all four wheels to be in contact with the  
floor surface.

Operation  
1. Fit the hose onto the inlet.  
2. If the dust outlet on the power tool is 100mm in diameter  
the hose can be connected directly onto the power tool.  
Attaching the dust bag  
1. Fit the dust bag over the outlet (3) (fig. J).  
3. If the power tool has a smaller outlet fit the 2 way adaptor  
onto the end of the hose. Connect a smaller diameter  
hose (not supplied) onto the adaptor and connect this to  
your power tool.  
2. Place the dust bag strap through the metal clamp.  
3. Pull the strap to secure the dust bag on the outlet cover  
(fig. K).  
Note. The 2 way adaptor is designed for fine dust ie.  
sanding dust. If larger particles are being collected and  
blocking occurs remove the cap to draw air into the hose  
and increase airflow.

Emptying the dust bag  
The dust bag can be emptied either on or off the dust  
collector. The bag should be emptied when the dust bag is  
approximately half full, performance will deteriorate as the  
dust in the dust bag exceeds this level.  
Turning on and off  
Ensure that the zip is not opened or the dust bag is not  
removed from the dust collector until the dust collector  
is turned off and the impellor has completely stopped  
rotating. Failure to do this can result in dust particles being  
distributed in the air.  
L
1. Insert the switch disabling  
insert and ensure the switch  
(1) is in the OFF position  
(fig. L).  
It is best to place the dust bag into a large garbage bag and  
then empty the dust directly into the garbage bag.
