ROUTINE MAINTENANCE
PACKING NUT CHECK
•
Check periodically
(and each time the pump is operated after a long downtime)
that the packing nut is not loosened, causing
otherwise the coming out of the product. To tighten the packing nut, use the clamping wrench
(ref. 20144).
The packing nut must
be tightened so as to avoid wastes of product, but not excessively to provoke pumping piston seizure and seals wear. In case
of persistent coming out of product, replace the seals.
•
To prevent the product from drying up on the piston rod, refill the cup with lubricant
(compatible with the product used)
.
•
Check periodically the air supply to the pump. Ensure the air is always clean and lubricated. In case of installation of a lubricator
on the air supply to the pump, it is advisable to keep its cup full of a mixture of water and antifreeze liquid
(dilution ratio 4:1)
.
