Pre-start check
Check all bolts and screws for
tightness. Ensure that all fittings are
secure.
This specific vacuum cleaner model
has been designed, built and
protected for vacuuming dusts and
solid materials only. SEE BELOW
To ensure the correct operation of
the vacuum cleaner, this must be
positioned protected against
atmospheric agents (rain, hail, snow,
fog, dusts in suspension, etc.) with
a n e n v i r o n m e n t a l r u n n i n g
temperature between 5°C and 45°C
and relative humidity not above 70%.
The work environment must be
clean, well-enough lit and devoid of
an explosive atmosphere.
The vacuum cleaner must not be
used in environments containing
substances in the form of liquids that
could vaporise at room temperature
and flammable dusts and gas.
All cables should be fully uncoiled
and never left wrapped around cable
reels or tied in loops.
OPTIONAL FILTERS
Besides the optional HEPA filter
(303.5263), and depending on the
dust to be vacuumed, the following
filters and accessories are also
available:
OPERATION
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.
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 checks are
best made periodically:
Check to see whether the filter is
worn or has become too permeable.
Make sure the gaskets of the motor
head base, the filter holder ring and
of the container are sealing correctly.
The electrical parts (plugs, switches,
cables, etc.) must not be faulty.
The screws and fastenings must
always be secure.
Make sure the container is not
overfull.
Check the integrity of the flexible
vacuum hose and accessories.
If the flexible hose is perforated, the
power of the cleaner will be reduced
and dust may leak into the
environment.
When contacting Trelawny SPT Ltd
or their agents, always quote the
details shown on the vacuum
cleaner serial plate.
FLOOR PICKUP ATTACHMENT
To change the filter, switch off the
vacuum cleaner and remove the
plug from the power socket, release
and remove the upper cap and then
loosen nut (A) in picture below.
The HEPA filter permits the trapping
of fine dust particles which have not
been contained by the primary
polyester filter.
If the vacuum cleaner features this
specific filter, its filtering capacity will
have to be periodically checked.

a plastic bag and dispose of
according to applicable local laws for
the type of dust recovered.
