Using the vacuum
Correct use of the vacuum
WARNING!
Before using this vacuum cleaner the
operators must read and understand all
information and instructions about the vacuum
cleaner and the substances for which the
vacuum cleaner has been designed, including
safety procedures for disposal of vacuumed
materials.
WARNING!
In case of foam or liquid leakages, turn off the
vacuum cleaner immediately!
Before using the machine, connect the suction pipe to the
inlet.
Keep long suction pipes as straight as possible.
Do not allow them to bend or twist as this will cause excessive
wear and clogging.
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", where a
deflector "5" in the filtering chamber subjects it to a centrifugal
action causing the heavier solids to deposit on the bottom of
container "6".
The primary filter will retain the lighter particles in the airflow
"3" as the air passes through it.
Lastly, the filtered air enters impeller "1" of the suction unit, it
is then exhausted through exhaust panel "2".
ATTENTION!
If the machine is used for fluids or wet
materials and fluid emerges from it, the
machine must be immediately switched-off,
cleaned and dried and all filters replaced.
Cleaning the primary filter
Vacuum gauge "1" is installed on the front part of the vacuum
(see fig. 4) and indicates the vacuum created within the
vacuum itself. This vacuum is expressed in millimetres of
water column. If the pointer is in the right (green area), the
filter will be in a good condition.
If the pointer swings to the left (red area), this means that the
filter is clogged and has a reduced filtering capacity.
In this case, it will be necessary to clean the primary filter.
Switch off the vacuum by pressing the OFF button "5" (red)
(fig. 4).
Operate the filter shaker handle "2" (fig. 7) several times in
order to detach the dust from the filter.
Wait a few minutes for the dust to deposit at the bottom of the
container, then empty this.
NOTE
If the vacuum gauge "1" (fig. 7) is still in the red
area, the suction pipe, may be clogged, and not
the filter.
Clean the pipe, if this is the case.

INSTRUCTIONS FOR USE
Emptying the container
WARNING!
Inside the vacuum cleaner there can be toxic
dust. The dust container emptying, servicing
and removal procedures must be performed
only by qualified technicians wearing
appropriate protective clothing. Do not operate
the vacuum cleaner if the filtering system is not
working properly.
Check the amount of waste in the container according to the
job in hand and to prevent it from becoming excessively full.
Before emptying container "1", first switch off the vacuum by
pressing the OFF button (red) then turn the main switch to
position 0 (OFF).
It is also advisable to clean the primary filter by using the
shaker handle.
Wait a few minutes for the dust to detach from the filter and
deposit in container "1".
Lift lever "4" under the inlet.
Container "1" will lower until it rests with its wheels on the
floor.
Grip handle "2" and remove the container, then empty out its
contents.
To make container "1" easier to empty, Nilfisk-Advance
supplies a lifting strap to be used when lifting the container by
use of a forklift or a crane. Insert the strap in the mounting
brackets on the container.
ATTENTION!
The container must not be emptied if it
contains dust classified as a health threat,
(Dust classifications M and H).
A plastic bag must be used for the disposal of
dangerous dust or, alternatively, the ABS
container with a lid.
The corresponding article numbers for these
items are given in Chapter 9.
To remount the container, fit it under filter unit "5".
Now push lever "4" downwards, allowing container "1" to lift
until it seals against filter chamber "5".
ATTENTION!
Check that when back in position, container
"1" is in a perfectly sealed condition.
To facilitate the container emptying and cleaning operations,
it is advisable to use plastic bags "1" as indicated in figure 10.
ATTENTION!
These bags cannot be used when the waste
contains liquids or sharp items.
