Samoa LARIUS SIRIO 60:1, Operating And Maintenance Manual, Page: 12 / 46

By “cleaning at the end of the work” is meant the cleaning to
carry out in case of use with a different product or if a long period
of storage 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 the minimum value necessary to
its continuous 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 inactivity, the operations of sucking and leaving
light mineral oil inside the pumping element are suggested.
ROUTINE MAINTENANCE
• Check periodically (and every time the pump is operated
after a long storage) the packing nut is not loosened, causing
otherwise the coming out of the product.
• To tighten the packing nut (L1) use wrench supplied (L2) .
The packing nut must be tightened so as to avoid wastes
of product, but not excessively to avoid the seizure of the
pumping piston and the wear of seals. In case of persistent
coming out of product, replace the seals.
• To prevent the product from drying up on the piston rod, refill
the packing nut
(L3)
with lubricant.
• Check periodically the air supply to the pump. Ensure the
air is always clean and lubricated.

K
Store possible dangerous fluids in proper con-
tainers. Their disposal must be performed in
accordance with the regulations in force about
the industrial waste goods.
L
Always close the compressed air supply and re-
lease the pressure in the plant before performing
any check or maintenance of the pump.
At the start of each working day, make sure that
the ring (L3) nut is filled with hydraulic oil (L4
)
; the
oil facilitates the sliding of the piston and prevents
any material which may have leaked out of the seals
from drying once the equipment has been shut off.
