Operation (dry use)
Setting up
1. Position the vacuum in the working area.
2. Ensure dust collection bag is fi tted to collection
cone.
3. Plug vacuum into power supply and switch on power
supply.
IMPORTANT!
Ensure vacuum is set to OFF position prior to
turning on power supply.
4. Disconnect fi lter link hose from top of secondary
fi lter housing.
5. Switch machine to ON position for 2 seconds and
place hand over fi lter link hose coupling. Feel with
hand whether machine is sucking or blowing.
6. If machine is blowing, wait 1 minute (for motor to
completely stop turning) and switch machine to
other direction using FWD/REV switch.
IMPORTANT!
Always remove key from FWD/REV switch.
This will lock switch and make it impossible
to change direction of motor when machine is
running.
7. Once machine direction is set correctly it is ready
for use with grinding machine.
Cleaning the primary fi lters.
After every 10-20 minutes of operation, the primary
fi lters will need cleaning as dust will buildup on the
inside of the fi lter socks. The easiest and most effec-
tive way to clear the dust buildup on the fi lter sock is
as follows:
Operation (dry use)
1. Switch the machine to the off position.
2. Using a large rubber hammer/mallet, tap the top
surface of the primary fi lter housing 10 times. While
this is happening you will notice all the dust from
inside the unit drop into the plastic bag attached to
the collection cone.
Changing the dust bags.
Once the dust bag has collected around 20 kg of
dust, to avoid lifting hazards caused by overfi lling of
dust bags, the dust bag should be changed.
1. Clear the primary fi lters of dust as outlined previous-
ly and agitate bag so that dust settles in the bottom
of the bag.
2. Switch the machine back into ON position (you will
notice the air is sucked from the plastic bag).
3. Tie bag off below the collection cone using a cable
tie or other bag tie.
4. Release elastic strap and remove sealed bag.
IMPORTANT!
Use extreme caution when releasing and re-
attaching elastic strap.
5. Using elastic strap, attach new empty plastic bag
(you will notice the air is sucked from the plastic
bag).
6. Machine is now ready to be used for duct collection
again.
IMPORTANT!
It is important to keep vacuum running during
the bag changing process. This will keep the
valve in the collection cone closed ensuring
no dust will drop out from within the collection
cone when bag changing is being performed.
This method will greatly reduce operator
exposure to fi ne dust particles when using
the equipment. It is strongly advisable that all
operators use a dust mask/respirator when
changing dust bags or performing mainte-
nance on the machine.
