Maintenance - dentalfarm BASE Evo D.O.S. User And Maintenance Manual

The microprojectors are ideally positioned in the centre of the working chamber to facilitate
use with both hands. We recommend to put back them in place on their support at the end
of the work.
The window is made of anti-scratch polycarbonate material, resisting to the rebounding
abrasive grains. We recommend to use a soft cloth to clean it and to remove the dust from
inside and the use of ptotection screens (code 1000532).

6. MAINTENANCE

Many of the components of any sandblasting machine are subject to wear: this is
caused by the circulation of abrasive media; the instructions for a careful maintenance of
the machine as well as the operations to replace the damaged or worn out parts are
specified here below.
/!\
ATTENTION:
Cleaning of the 5my filter
A 5my filter, fitted on the right side of the sandblaster, prevents fine dust from damaging
internal components. Remove the inspection cap every 2-3 months and blow the filter with
compressed air to clean it from dust sediment.
Replacement of the polycarbonate window
Although the window is anti-scratch, it may be damaged by an extensive use (or a bad
maintenance). Replacement is very simple: locate the screws which fix the window to the
hinges and unscrew them.
Replacement of the plastic protection screens of the glass window: remove the fixing
clips, clean accurately the glass and place a new protection screen.
Replacement of gloves
The gloves are made of highly resistant rubber, but are subject to the natural ageing of
rubber and to the action of sweat (produced by hands). This cause them to dry up. To
replace them, unscrew the flange screws and fit a new pair of gloves into the proper seat.
Replacement of the devesting nozzle
The devesting nozzle, even if made of tungsten carbide, known as a very hard material,
will inevitably wear out, due to the continuous flow of abrasive and will therefore need to
be replaced periodically. Remove the nozzle cap and insert a new group, paying attention
to thoroughly fit it into the plastic body.
Replacement of nozzles
Nozzles of the microblasting tanks are also subject to wear and need to be replaced. To
do this, unscrew the ring nut and assemble the new nozzle.
Before carrying out any maintenance operation inside the working
chamber or technical repair of the connections, remove the feeding
cable both from network socket and from the rear of the machine; in
such a way, both the electric and pneumatic installation of the unit will
be fully disconnected.
