Many motor failures have as immediate consequence an abrupt and important drain leakage increase both in
terms of flow rate and impurities present in the fluid.
If the motor case is flushed, before performing the drain leakage check, pls. remember
to exclude the flushing system first.
7.3 – Warranty Conditions
Parker Calzoni guarantee the motors for failures due to material defect and erroneous machining for 12
months after the unit installation; the period of 12 months is evaluated considering the motor running 8
hours per day.
For repaired motors the warranty period is reduced to 6 months.
For units used in a multiple shifts working condition, the warranty period is reduced proportionally (i.e.
the motor works for two shifts of 8 hours per day, the warranty period is reduced to 6 months).
Anyhow, the warranty period ends after 18 months from the consignment of the motor to the end user
customer.
The examination of the warranty claim by Parker Calzoni is based upon the assumption the customer has
fulfilled all the contract duties.
For the examination of a warranty claim Parker Calzoni need to check the complete motor. Any kind of
service operation performed by the customer on a unit object of warranty claim (i.e. disassembly of the
motor components) causes the warranty loss.
