OPERATION & MAINTENANCE
General safety
precautions
Maintenance jobs must always be
performed by skilled technicians,
trained to carry out their specific
jobs. In the case of this machine,
these are:
Mechanical maintenance
Electrical maintenance
The Safety Manager has the precise
duty of determining the professional
capacities and skills of such
persons.
Before doing any maintenance job,
the safety manager must:
Make sure there are no unauthorised
persons in the work area.
Make sure the necessary tools are
on hand and that these are in good
condition.
Make sure that lighting is adequate.
Make sure the maintenance
engineer is equipped with all
approved individual protection
devices needed for the specific
operation (gloves, eyewear, shoes,
etc.)
Make sure the maintenance
engineer has carefully read the
instructions contained in this manual
and knows how the vacuum cleaner
works.
Before carrying out a maintenance
job, the maintenance engineer must:
Disconnect the plug from the power
socket.
Work done on motors or other
electrical component parts must only
be performed by a specifically
trained electrician, authorised by the
Safety Manager.
Always use tools that are in perfect
condition and specifically made for
the operation to be done.
The use of unsuitable tools or tools
not in good condition could cause
serious damage.
Maintenance checks
For efficient vacuum cleaner
operation, a number of controls
are best made periodically:
Check to see whether the filter is
worn or has become too permeable.
Using the filter cleaning
system.
These following operations must
only be performed with the machine
switched off once the motor has
come to a complete halt. The filter
cleaning system is best operated
every time before use and after
prolonged operation.
This should be emptied when the
vacuumed material has reached 3/4
of maximum capacity.
On the front of the vacuum cleaner is
a vacuum meter indicating the
degree of vacuum inside the vacuum
cleaner.
If, with the vacuum cleaner working
and the vacuum inlet free, the
vacuum meter lever indicates an
irregular depression level, the filter
will have to be shaken by means of
the special lever.
Make sure the sealing gaskets of the
motor head base and of the
filter - holder ring and of the Hopper
are working efficiently.
The electrical parts (plugs, switches,
cables, etc.) must not be faulty.
The screws and nuts must always be
tight.
Make sure the ENDLESSBAG
section is not overfull.
Check the integrity of the flexible
vacuum hose and accessories to be
used.
If the flexible hose is perforated, the
power of the cleaner will be reduced
and dust and liquids will leak into the
environment.
Dust containment bag
This should be emptied when the
vacuumed material has reached 3/4
of its maximum capacity.
Procedure for revealing a new
section of the dust containment
bag.
Stop the vacuum motors by pressing
the relevant STOP switches and
disconnect from the power socket.
While performing this operation it is
best to wear a dust protection mask.
Use two ties at two points 3 - 5cm
apart just below the filter chamber
Cut the bag between the two ties.
If the arrow of the vacuum meter
stays in the red area even after
cleaning the filter, the hose or
suction accessory could be blocked.
In this case, clean and remove the
blockage.
MAINTENANCE
This section describes the control
and special maintenance operations
crucial for keeping the vacuum
cleaner in perfect working condition.
Any other jobs which might be
necessary to eliminate operating
faults must be expressly authorised
by the manufacturer. In such cases,
always supply the identification
details of the cleaner.
In the case of major repairs, it is best
to contact an authorised dealer.
Pull down a length of new bag from
the chamber until it reaches the
support plate.
Empty the contents of the bag into a
special waste disposal container in
accordance with laws applicable in
the country where the vacuum
cleaner is used.
Remove plastic cap and replace
vacuum hose.
