GENERAL MAINTENANCE
DAILY
• Clean the filters;
• Clean the nozzles;
• Clean all the paint circuit with a specific product;
PERIODICALLY
• Check the pump gaskets tightening
(replace the gaskets, if
necessary).
• Clean the movable parts from the paint deposits
(spray guns,
etc.)
;
• Check that the tubes and all the fittings are correctly tightened.
OPERATION
•
Dip the material pumping hose (
K1
) into the product tank
(
K2
)
(if the pump is fixed on the air hoist, follow the procedure
described in the manual of use and maintenance of the air
hoist)
CLEANING AT THE END OF
THE WORK
By "cleaning at the end of the work" we mean the cleaning to
carry out in case of use with a different product or if a long period
of downtime is foreseen.
•
Stop the air supply to the pump.
•
Dip the material pumping hose into the washing solvent
tank
(check its chemical compatibility with the product being
used)
.
•
Make compressed air flow into the pump. It is advisable to
adjust the air pressure to minimum necessary to its conti
-
nuous working.
•
Point the spray gun or the delivery valve at a container and
drain all the product left inside the pump till a clean solvent
comes out.
•
Now, stop the air supply to the pump and drain the residual
pressure.
•
In case of long downtime, we suggest to duly suck and
leave light mineral oil inside the pumping unit.
•
Make the compressed air flow into the pump. It is advisable to
adjust air pressure to minimum necessary for its continuous
working.
•
When the product chamber is full, pump will start working
and stopping. Pump will start working again any time the
trigger of the spray gun is pressed or the delivery valve is
open.
• The pump has been adjusted at our factory with light mineral
oil and a part of it could be left inside the pumping element.
Point the spray gun (
K3
) or the delivery valve at the collecting
tank (
K4
) and drain the product left inside the pump till the
material to be used has come out.
•
In case of long downtime during the use with the plant
(for
example, all night long at the end of the working day)
, ensure
the product you are using can be left inside the pump and
the different pipes without drying.
In this case, it is enough to stop the air supply to the pump
and drain the residual pressure in the circuit acting on the
delivery valve or on the pump bleeder valve.
Check all the fittings for connection of the different
components
(pump, flexible hose, spray gun, etc.)
before using the equipment.
Always avoid pump idling: this operation could
damage the pneumatic motor and the sealing
gaskets.
Store possible dangerous fluids in proper
containers. Their disposal must be performed in
accordance with the regulations in force about
the industrial waste goods.
Discharge the pump pressure
(opening the
discharging valves
) before any maintenance
operation.
