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
container. 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
manufactured 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. Donʼt 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 guarantee an optimal air speed within the suction
hose. When you lift the floor nozzle off the surface that
is being cleaned and the manometerʼs 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. 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
manometerʼs needle does not return to the green zone,
the main filter needs 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 pointing 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 dustclass your machine is suited for (see
identification plate).
The machine must not be used for several categories at
the same time, unless suitable accessories are used.
Dust Class “L”
(Light hazard - defined by EN 60335-2-69).
This industrial vacuum is approved according to
EN 60335-2-69 for category of use “L” and is fit to
suck dry, non flammable and non-toxic dust with
MAK>1mg/m? values; the clean air is conveyed back
into the place of work.
