INSPECTION, ORDINARY & EXTRAORDINARY MAINTENANCE, SERVICE & CLEANING
3.7.1
PRECAUTIONS
Before proceeding to the periodic procedures of inspection, maintenance, repairs & cleaning it is necessary to
discharge the internal pressure, through a duct converged in a safe area, to avoid damage to persons or things and
to verify the occurred discharge phase by means of control devices (pressure gauges).
It is always necessary to verify the non-existence of potential explosive atmospheres and the impossibility to trigger
off.
The user must certify that the operator is opportunely instructed to carry out all the safety procedures & hygiene in
the work areas according to the protocol in order to avoid any eventual risks deriving from the operations mentioned
above.
3.7.2
ORDINARY MAINTENANCE AND CLEANING
After a normal daily usage, wash the inside of the head with clean water without any additives. Carry out an internal
check after 100 hours and check the conditions of the internal parts (gears, bearings, dynamic seals). The incorrect
choice of the O-ring material (dynamic seals) can cause an irregular function and a rapid deterioration of these parts.
In presence of dimensional alterations (swelling) of the dynamic seals (OR+PTFE), control the compatibility of the O-
rings with the liquid used; if they result non-compatible, contact our Technical Department.
The cleaning stages are to be carried out regularly in view of the function and compulsory in the presence of matter
a/o explosive powders on the head and nozzles (independently from the settled thickness)
For internal and external cleaning, it is necessary to use non corrosive products or solutions, suitable to remove the
work residue, and that do not damage the O-ring surfaces and internal gears. For the cleaning operations do not use
aggressive chemical detergents a/o mechanical systems that can cut or deform the head.
