When the vacuum is powered, suction is created at the pipe
inlet and this sucks in the waste material.
This waste material passes through the pipe and accessories
through the inlet "4" until it reaches container "6".
A manufacturer's dustbag can be used in the standard machine.
To release the container, unfasten the stainless steel clamp
and lift off the upper part with the motor/filter section.
Fix the dust bag as follows:
Pierce the dust bag´s perforation and place it in the lower
container.
Pull the blue dust bag plastic plate over the suction inletwith
both hands.
Unfold the dust bag carefully.
Replace the top containerand lock the stainless steel clamp.
Note
The suction efficiency depends on the size and quality of the
dust bag.
Use original manufacturer's bags only.
If non-manufacturer's dust bags are used, and airflow re-
stricted, overheating of the motor and subsequent damage
may occur.
"H" class only:
A "Safe Bag" system is used for the "H" class machine.
The Safe Bag system consist of a dust bag approved by BIA
for class "M".
The dust bag is reinforced with a mesh and incapsulated in a
plastic bag.
Insert the dust bag into the container. Its flange must point at
the inlet.
Now push the flange onto the inlet until it fits tight.
The plastic bag has to fit the bottom and walls of the contai-
ner.
Tear the edge of the bag above the edge of the container and
smooth it down.
"Safe Pack" only:
Ensure that the motor and top container fits correctly on top of
the safe pack unit before starting the machine.
The safe pack unit is a "throw away" unit, which is manufactu-
red to hold dust hazardous to health.
8.2 - Cleaning the main filter (standard Machine)
To keep suction power at a constant level the filter must be
kept as clean as possible by shaking it at regular intervals.
Dismount the motor unit by opening the stainless steel clamp.
Take the bottom plate of the filter and pull it upwards and
shake slightly.
Don't remove the hose while shaking.
The filter must not be washed or brushed!
"H" class only
The system is fitted with a vacuum gauge / manometer that
allows you to monitor the minimal airflow in order to guaran-
tee an optimal air speed within the suction hose.
When you lift the floor nozzle of the surface that is being clea-
ned and the manometer's needle moves from the green zone
into the red one, the dust bag is full and needs to be replaced.
Attention: The level of material inside the dust bag has to be
checked at regular intervals.
C316
are used, and airflow re-
Monitoring the level strictly by means of the manometer is not
a 100 per cent guarantee that the bag is not full.
Attention: There is no device for cleaning the main filter.
When the dust bag has been replaced and the manometer's
needle does not return to the green zone, the main filter ne-
eds to be replaced as well.
8.3 - Emptying the container / changing the bag (fig. 9)
First of all, switch the motor off and wait a moment until the dust
inside the machine has settled down. Then you can separate the
dust collecting container from the upper part of the machine:
Switch the motor on in order to prevent dust falling down from
the filter.
Open the stainless steel clamp, now lift off the upper part and
let it rest on the support frame.
Replace the disposal system, the bag.
Lift the upper part above the machine.
Switch the motor off.
Put the upper part on the machine and secure by locking the clamp.
"H" class only: (fig. 10)
Using a Dust Safe Bag system, Dust class H
Once the dust bag is full
Open the clamps and lift the upper part.
Switch the motor on in order to prevent dust falling down from
the filter.
Leave the hose connected or close by shutter cap!
Now lift off the upper part and replace the safe bag disposal
system.
After opening the appliance detach the plastic bag lying across
the bin rim carefully, press the opening together and seal it.
Detach the back of the connecting flange by briefly and firmly
pressing downwards at an angle, holding the front firmly on
the connection piece as you do so. The flexible plastic-pipe
joint is now visible and can be tied off securely with the plastic
cable tie simply by pulling it together.Having ensured that no
dust can escape, now also detach the front part of the flange
from the connection piece.
Fitting the Dust safe Bag
Place the special dust bag flat in the bin with its opening poin-
ting towards the bin inlet. Now slide the opening in the special
dust bag on to the bin inlet as far as it will go – without any
turning. Then fold the plastic bag down over the bin rim.
Now pull the part of the plastic bag overlapping the bin rim
tight against the flange (before reattaching the top and bottom
sections of the vacuum cleaner).
Lift the upper part above the machine.
Switch the motor off.
Put the upper part on the machine and secure with locking
clamp.
9 - Dustclasses
Use in compliance with the standards. Check which dust-
class your machine is suited for (seeidentification plate). The
