Replacing the absolute filter
When installed, the absolute filter is replaced in the following
way:
–
loosen the clamp fixing the filter assembly on the
machine;
–
remove suction pipe from the lower spigot;
–
loosen the clamp fixing the top cover of the absolute filter
chamber;
–
it will now be possible to remove the absolute filter "1"
and to replace it with a new one;
–
remount the top cover and fix the clamp;
–
fix the suction pipe;
–
fix the filter assembly back into position and tighten the
clamp.
The dismounted and replaced absolute filter must be covered
with a nylon bag and disposed of in the appropriate way.
Replace the primary filter and the absolute filter with particular
care, above all use the P3-type mask.
NOTE
The absolute filter is toxic waste and must be
treated as such. Hand it over to one of the
authorities authorized to dispose of such
materials.
General recommendation.
Please pay special attention to the grounding
connections when disassembling and
assembling the machine, when replacing filter
etc.
Checking the condition of the hoses
To ensure the vacuum operates in the best possible way, the
entire air suction circuit must be perfectly tight.
It is necessary to check the condition of hose "1" that
connects the main filter with the absolute filter chamber.
Check that it is correctly fixed. Check the hose "2" connecting
the absolute filter chamber to the suction motor, and the
hose"3" connecting the suction motor to the exhaust.

INSTRUCTIONS FOR USE
Checking the condition of the suction fan
Dust deposits could unbalance the fan, creating abnormal
vibrations and quickly wearing the bearings.
Ask for technical assistance from Nilfisk-Advance or one of
the manufacturer's authorized after-sales service centre in
these cases.
Remember to remove the suction unit from the casing, it will
be necessary to proceed with the aid of lifting means and safe
anchoring.
The unit may weigh as much as 50 Kg.
Periodically check to make sure that there are no dust
deposits on the turbine casing "2" when work is carried out in
particularly dusty environments.
If there is dust or oil mist in the environment, make sure that
the cooling holes of cap "1" do not become clogged. This
could prevent the motor from being efficiently cooled and lead
to activation of the thermal protector or, worse still, cause the
motor to actually break down.
