Inspections prior to starting

1. Inlet
Prior to starting, check that:
■ The filter is installed and in good conditions;
■ All latches are tightly locked;
■ The vacuum hose and tools have been correctly fitted
into the inlet (1).
■ The polyliner is installed, if applicable.
■ The filter is intact before using the machine as follows:
vacuum fine inert dust (e.g.: talc, chalk, scagliola...) and
make sure it isn't blown out of the outlet.
■ The motor cooling air filters (2, Fig. 5) are cleaned.
■ The filter chamber gasket is properly sealing (see "Filter
chamber seal check" section on page 11).
Do not use the device if the filter is faulty.

WARNING!

Starting and stopping

WARNING!
Lock the caster brakes (1) before starting the vacuum
cleaner.
Standard version
■ Turn the manual motor starter (2) to the "I" position to
start the vacuum cleaner. Turn the manual motor starter
(2) to the "O" position to turn the vacuum cleaner off.

Vacuum cleaner operation

Check that the data on the machine's identification plate
correspond to the Zone classification and to the maximum
allowable temperature to avoid dust ignition in the work area.
Check that the vacuum cleaner specifications have not been
modified, otherwise the Declaration of Conformity is no longer
valid.
Static electricity can cause sparks, with the consequent risk of
explosion! Therefore, make sure the electrical socket and plug
are connected to earth.
Use an insulation tester to check the resistance of the earth
connection from the inlet to the end of the vacuum pipe (and
the antistatic hose connecting to the electrical mains on air
compressed models): the resistance must be lower than 1 MΩ
(106) Ohm.
Check the continuity of the ground view (green-yellow
protective conductors) and make sure that they are in perfect
conditions.
Check for loose electrical or mechanical connections.
Be sure that the machine is turned off before connecting it to
an energy source. Connect the machine to an energy source
outside the ATEX Zone (unclassified zone). If the machine
has an ATEX electrical plug certified for the area it is used in,
it can be connected to an ATEX certified socket in the same
type of zone with the same rating.
The operator shall take care not to generate dust clouds while
cleaning the area, mostly around the vacuum cleaner itself.
Do not remove hoses during operation, always wait until the
machine has stopped.
If a preseparator must be used, check that it is well grounded.
Only use antistatic hoses, both for suction and connecting the
preseparator. Do not use the machine to suck up large objects
or particles because they can knock against each other,
causing sparks.
Do not rub or hit the floor with steel tools, as they can produce
sparks under friction. Only use collectors and suction caps
that can be replaced with original Nilfisk antistatic spare parts
to clean the floor.
