OPERATION & MAINTENANCE
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.
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.
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.
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.
Make sure the sealing gaskets of the
motor head base and of the
filter - holder ring and of the container
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 container 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.
The filter cleaning system is best
operated every time before use and
after prolonged operation.
On the side of the vacuum cleaner
near the On/Off switch 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.
If the needle of the vacuum meter
stays in the low even after cleaning
the filter, the hose or suction
accessory could be blocked. In this
case, clean and remove the
blockage.
